Airtightness from a<br />
contractor’s perspective<br />
Air leakage through cracks, gaps, holes and improperly sealed elements such as doors and windows can cause a<br />
significant reduction in the performance of even thermally insulated building envelopes. Contractors have a key role<br />
to play in the installation of effective air barrier systems which have become essential in achieving the most effective<br />
means of controlling and reducing air leaks.<br />
As thermal insulation requirements have increased over the last few years, the proportion of energy lost<br />
through air leakage has become more evident. The ever-increasing thermal insulation required will, however,<br />
be rendered largely ineffective unless the airtightness of the structure itself is addressed. Air leakage greatly<br />
reduces the effect of thermal insulation; therefore if energy efficiency is to be improved within buildings, this is<br />
the most critical area to focus on.<br />
The two main ways to achieve airtightness in the building envelope are internally or externally, or in other<br />
terms, “inside of the services zone’ or ‘outside of the services zone’. For the contractor, the use of traditional<br />
internal air barriers can be more complex and costly to install, due to the need to accommodate building<br />
services such as electrical, lighting, heating and drainage systems. An internal air barrier is only as good as it’s<br />
installation. If all the service penetrations are not adequately sealed, performance will be compromised.<br />
For many years, external air barriers have been commonly used in North American building design and<br />
construction. By moving the air barrier to the external side of the structural frame, external air barrier<br />
systems such as Wraptite ® from A. Proctor Group allow for an almost penetration-free airtight layer, which<br />
can be installed faster and more robustly. This offers an effective but simple system comprising a self-adhesive<br />
vapour permeable air barrier membrane, plus vapour permeable sealing tape, Wraptite Corners and Wraptite<br />
Liquid Flashing, and provides effective secondary weather protection while preventing trapped moisture and<br />
air leakage. Far simpler than internal options an external air barrier system like Wraptite will maintain the<br />
envelope’s integrity, with less building services and structural penetrations to be sealed, and less room for error.<br />
The Wraptite air barrier system from the A. Proctor Group is the only self-adhering vapour permeable air<br />
barrier certified by the BBA and combines the important properties of vapour permeability and airtightness in<br />
one self-adhering membrane. This approach saves contractors costs on both the labour and materials required<br />
to achieve the demands of energy efficiency in buildings.
Wraptite ® - Trinity, Manchester<br />
An example in use is the administrative headquarters building of the Royal College of Pathologists in London<br />
where the Wraptite system was installed as a solution for airtightness, weather protection and breathability.<br />
Cladding contractor Windell installed the Wraptite System as an external air barrier and alternative to a<br />
traditional standard breather membrane. The use of a standard membrane would have required mechanical<br />
fixing and provided some challenges given the concrete structure of the building. As an alternative, the<br />
Wraptite self-adhesive membrane was applied, quickly and easily to the external envelope in continuous<br />
pieces.<br />
George Marcantonio, the Site Manager of Windell, commented: “The application of the self-adhesive Wraptite<br />
System has proven really easy to use, and quick to apply, with no requirement to return for additional<br />
fixing or accessories. We will certainly be using the system for future projects and recommend it without<br />
hesitation.”<br />
By reducing the likelihood of potential failures to meet designed airtightness levels, the Wraptite System helps<br />
contractors to ensure compliance with building regulations, achieving an effective airtight barrier, whilst saving<br />
time and cost on site.<br />

With time and work pressures, we all know how easy it is to get<br />
caught up in the cycle of ticking off the ‘to-do list’ and going from<br />
one job to the next.<br />
For roofing and cladding operatives in particular, justifying time away<br />
from jobs can be difficult but sometimes it’s important to stop and take<br />
stock, see what’s new in your sector and perhaps learn about the latest<br />
developments that will assist you as an individual or business going<br />
forward.<br />
That’s why, alongside the NFRC, we’ve brought together the leading<br />
manufacturers and suppliers of roofing, cladding, and associated<br />
products and materials for one-day only at Old Trafford football club,<br />
Manchester, on 2nd October <strong>2019</strong>. At Contractor’s Day – sponsored by<br />
Quantum Insulation – you’ll be able to get up close to the latest<br />
launches, pick the brains of technical experts, network with likeminded<br />
individuals, and listen to and take part in seminars and<br />
debates on the key issues affecting the roofing and cladding sectors.<br />

CONSOLIDATION<br />
GOOD FOR CLADDING<br />
Vivalda Group has acquired the cladding<br />
manufacturer MSP Scotland.<br />
Vivalda Chairman Peter Johnson is delighted<br />
with the acquisition of MSP, which will<br />
continue to trade under the brand that was<br />
established in 1966. Speaking from Glasgow,<br />
he said: “The MSP name is well known<br />
across the UK as a provider of both branded<br />
fascia boards, as well as its bespoke coated<br />
aluminium façade solutions. I’ve been<br />
impressed with the level of skilled<br />
technicians and engineers based here at<br />
Cumbernauld – which I am sure will prove to<br />
be a great asset to the Vivalda Group. We<br />
intend to invest in people and technology<br />
here at MSP, to create a world-class façades<br />
manufacturing and fabrication facility.<br />
There’s a great fit between Vivalda and MSP,<br />
both strategically and culturally, and I am<br />
confident that this acquisition will bring<br />
further growth to our business.”<br />
Johnson added that the sale of MSP was a<br />
further sign of consolidation within the UK<br />
cladding market, following the Grenfell Tower<br />
disaster of 2017: “While the jury is still out on<br />
the culpability of those responsible for the<br />
failings at Grenfell, the cladding sector has<br />
seen big changes in the past two years, with<br />
many low quality, smaller suppliers exiting the<br />
market. The days of supplying untested fascia<br />
board for high rise buildings is thankfully a<br />
thing of the past, with the use of ACM and HPL<br />
on tall buildings now effectively outlawed.<br />
While not directly related to Grenfell, this deal<br />
shows that there is consolidation happening<br />
within our market – something I see as a<br />
positive sign in terms of safety and efficiency.<br />
This will all be good news for contractors and<br />
architects. In terms of products, we see a big<br />
future in fully fire-resistant 3mm aluminium<br />
cladding, the type of which is manufactured<br />
here at MSP.”<br />

DRYDEN’S MIND ON<br />
CHARITY CLIMB<br />
An intrepid member of the SIG Design<br />
and Technology team is limbering up to<br />
climb one of the world’s highest<br />
mountains, all in the name of charity.<br />
Ian Dryden, National Specification<br />
Manager for the roofing supplies<br />
specialist, will be climbing Kilimanjaro,<br />
the highest mountain in Africa, to raise<br />
vital funds for the Samaritans and MIND<br />
and to raise awareness of the huge<br />
challenge of mental health issues in the<br />
UK construction industry.<br />
Inspired to sign-up for the climb after<br />
learning of the construction industry’s<br />
mental health crisis, Ian was shocked to<br />
discover skilled construction workers<br />
were ten times more likely to die from<br />
suicide than an accident while in-work.<br />
Beginning his epic mission on Boxing<br />
Day, which will see him climb more than<br />
5,895 metres above sea level, Ian<br />
commented: “There is a huge focus on<br />
physical safeguarding in the construction<br />
industry, which is crucially important,<br />
but it’s essential to look after your<br />
mental wellbeing too.<br />
“Approximately one in four people in the<br />
UK are affected by a mental health issue<br />
each year, and services such as the<br />
Samaritans and MIND play a pivotal role<br />
in getting help to those in need. Scaling<br />
Kilimanjaro will be a mammoth<br />
undertaking, but I can think of no more<br />
worthwhile cause for which to do it!”<br />
Ian’s journey to Africa will begin on 26th<br />
December and he is set to summit<br />
Kilimanjaro on New Year’s Day. To learn<br />

CHARITY RACE DAY<br />
RAISES £52,000<br />
Richard Soan Roofing Services announced<br />
that its <strong>2019</strong> Charity Race Day event<br />
raised an incredible £52,000 for Teenage<br />
Cancer Trust.<br />
Held annually<br />
at Brighton<br />

the event<br />
included an<br />
auction,<br />
champagne<br />
reception,<br />
lunch and an<br />
afternoon’s racing, with all proceeds going to<br />
the charity.<br />
The marquee, perfectly located beside the<br />
final furlong of the course, was bustling with<br />
320 guests from the roofing and construction<br />
industry, attending what has become a regular<br />
highlight on their summer social calendar.<br />
With a glass of fizz in hand, attendees settled<br />
down to a sumptuous three course meal<br />
punctuated by fundraising games before the<br />
racing began. Richard has been hosting these<br />
events now for many years and knows how to<br />
work the crowd! As a seasoned auctioneer,<br />
he created what can only be described as a<br />
frenzy during the 18 auction lots held<br />
throughout the afternoon. This became an<br />
entertainment in itself, causing much hilarity<br />
to those looking on. By the end of the day,<br />
over £52,000 had been raised, which in the<br />
words of Richard “blew him away”. “It is the<br />
most we have ever raised” he went on to<br />
explain, “but I can only thank the amazing<br />
generosity and support of all those who<br />
attended. It is such a worthy cause and every<br />
penny goes into making a difference.”<br />

ECIC is warning roofing contractors working have separate cover – which was not in place.<br />

case was due to appeal the High Court’s decision<br />
in early <strong>2019</strong> but instead settled out of court,<br />
This could leave them exposed if they are found<br />
prior to the appeal hearing.<br />
to be at fault in an insurance claim. The warning<br />
follows an out of court settlement which has left Ian Hollingworth, Technical Claims and<br />
insurers and contractors in the dark about the Relationship Manager, ECIC, commented: “The<br />
extent of cover offered by Project Policies in the out of court settlement has left insurers<br />

urgent clarity over policyholder and subcontractor’s<br />

READYFIX EXPANDS<br />
ITS CAPACITY<br />
Readyfix has further invested in a second<br />
warehouse at its premises on Croft Street.<br />
The business, which employs 35 staff, added<br />
an extra 350 pallet spaces, equivalent to the<br />
size of a football pitch, allowing the 27-yearold<br />
firm to hold onto their ‘huge stocks’<br />
promise as they continue to grow.<br />
Established in 1992 by Richard Burwood,<br />
Readyfix supplies construction site<br />
materials, fixings and consumables to some<br />
of the country’s largest housebuilders and<br />
contractors, as well as sub-contractors and<br />
independent tradespeople throughout the<br />
North of England. The company says it sets<br />
itself apart by offering impeccable customer<br />
service and next day/same day deliveries by<br />
their own drivers.<br />
MD Greig Burwood, who runs the company<br />
with his father and four brothers, added:<br />
“Our primary focus is to keep to our<br />
promises; prompt response, and on-site,<br />
on-time deliveries. We have an excellent<br />
team to enable us to do this and the<br />
warehouse extension is proof that we are<br />
willing to invest to make sure our customers<br />
continue to be fully supported and their<br />
needs met.”<br />
Sales Director Mark Burwood commented:<br />
“This new warehouse extension will enable<br />
us to offer an even better service throughout<br />
the North of England. We’re proud to serve<br />
the construction sector with our<br />
commitment to responsiveness. Our large<br />
inventory now allows us to deliver orders of<br />
stocked items even quicker to meet<br />
customer demand.”<br />
RIDING4DREAMS TEAM’S HARSH REALITIES!<br />
As if being overweight (their words not ours!),<br />
50+ years old, and first-time cyclists with<br />
less than 6 months to prepare for a 217-mile<br />
3-day ride from Thorpe Park to Disneyland<br />
Paris wasn’t enough of a challenge, the UK<br />
weather decided to get in on the act when the<br />
Riding4Dreams team set off on Thursday 27th<br />
July <strong>2019</strong>.<br />
Radmat’s Mark Harris enjoys a well earned drink!<br />
Officially the hottest day on record in the United<br />
Kingdom, with the temperature reaching 38.7°C the support vehicles was less than 200 foot away.<br />
(101.7°F) in the shade, this fundraising cycle ride<br />
The rest of the day’s 5 hours of cycling, and<br />
in support of the Dreamflight charity’s annual trip<br />
3,000ft of climbing, continued with a mix of cloud<br />
to the Orlando theme parks for 192 Children with<br />

With ‘feels like’ temperatures of 41°C, the 14 experiencing repeat punctures within 100 yards of<br />
riders needed every one of the four 15-mile pit the previous one! A journey of 78 miles ended<br />
stops on the 73-mile journey to refill their water with a much-needed beer and bike cleaning<br />
bottles and rehydrate. After a gruelling 5 hours of session, followed by rider cleaning which resulted<br />

a few much-needed cold beers.<br />
was much appreciated, as was the jubilant<br />
Friday was a massive contrast, starting very welcome from the five support crew. A quick<br />
overcast and cool, and for good measure the first celebration, photo session and popping of<br />
of three tyre changes due to punctures. The first champagne corks preceded the need to load all<br />
15 miles ended with the French weather throwing the vehicles up, have a wet wipe and hit the road<br />
as much water as it could at the team, including for the Eurotunnel trip back to a welcome home<br />
a significant thunder storm that saw a lightning party in Shepperton where the team were met by<br />
strike hit a metal roof less than 8 feet from three family and friends giving a hearty (if somewhat<br />
of the riders! Fortunately, respite in the shape of off key) rendition of ‘We are the Champions’!<br />

CONSTRUCTION: A LICENSE TO BUILD<br />
Extra paperwork can be a hassle – whatever industry you are in – but Jackie Biswell<br />
(below), of Apex Roofing, explains why she’s pleased plans to introduce a mandatory<br />
licensing scheme for all UK construction firms is being widely embraced across the sector.<br />
Cowboy builders; rogue traders; rip-off<br />
roofers. They all give our profession a bad<br />
name.<br />
So much so, in fact, that last year a study by the<br />
Federation of Master Builders revealed that these<br />
charlatans are causing a third of homeowners to<br />
put off making home improvements.<br />
This came swiftly in the wake of another scandal<br />
exposed by BBC journalists who were able to set<br />
up a fake handyman profile on MyBuilder.com, a<br />
website which helps consumers find tradesmen.<br />
The reporter was also able to pretend to be one of<br />
his customers, submitting glowing reviews to give<br />
his profile extra credibility.<br />
It’s little wonder that the FMB, which estimates<br />
that the UK economy is missing out on £10 billion<br />
of work every year because of the problem, has<br />
campaigned for the Government and industry to<br />
back the introduction of a licensing scheme for<br />
the UK construction sector.<br />
What does it mean?<br />
Currently, too few builders and contractors are<br />
subject to meaningful checks to ensure<br />
competence. This is because, unlike the gas and<br />
electrical trades, anyone in the UK can set<br />
themselves up as a builder.<br />
On top of this, there are plenty of builders who<br />
take on labourers – also known as their mates<br />
from the pub – uninsured, untaxed and with no<br />
scaffold or hoisting for cash in hand.<br />
The proposal is to make licensing mandatory<br />
across the construction industry – essentially<br />
barring anyone shown to be incompetent or who<br />
undermines the standards of the industry.<br />
A report, Licence to build: A pathway to licensing<br />
UK construction, which follows<br />
independent research by Pye<br />
Tait, was officially launched<br />
at the House of Lords in June<br />
explaining its implementation<br />
and how it aims to improve<br />
both the quality and reputation<br />
of the sector.<br />
The model put forward recommends that the<br />
licence is administered by a central body and that<br />
the licence itself would not be a prohibition in<br />
terms of cost nor bureaucracy. The fee would be<br />
set according to turnover, with the largest firms in<br />
our sector paying something in the region of<br />
£1,000 every three years and the smallest firms<br />
would pay around £150 every three years.<br />
Brian Berry, Chief Executive of the FMB, said: “The<br />
vast majority of builders and homeowners want to<br />
see the construction industry professionalised and it<br />
is time for the government to act. It’s unacceptable<br />
that more than half of consumers have had a<br />
negative experience with their builder. However,<br />
we shouldn’t be surprised by this given that in the<br />
UK, it is perfectly legal for anyone to set up a<br />
building firm and start selling their services<br />
without any prior experience or qualifications.<br />
This cannot be right given the nature of the work<br />
and the potential health and safety risks when<br />
something goes wrong. In countries like Australia<br />
and Germany, building firms require a licence and<br />
we want to see the UK government regulate our<br />
industry in a similar manner.”<br />
What happens now?<br />
Construction is often accused of falling behind<br />
other industries – in terms of its uptake of new<br />
technologies, its diversity record and its working<br />
practices.<br />
Some of this might be unfair. But what<br />
has never been in dispute is that it<br />
lags behind hugely in terms of<br />
ensuring competence and<br />
consumer protection.<br />
This explains why it is<br />
consistently shamed by widespread<br />
media reports of rogue traders.<br />
A mandatory licensing scheme is the only way to<br />
stamp this out and a group of major construction<br />
industry bodies has now joined forces to create a<br />
Construction Licensing Task Force which will be<br />
chaired by Liz Peace, former Chief Executive of<br />
the British Property Federation.<br />
On the board will be representatives from a series of<br />
professional bodies in our industry which want to<br />
transform our industry into a world-leading sector.<br />
But it is not just the large organisations which are<br />
striving for change here.<br />
In an unusual display of support for additional<br />
‘red tape’, almost 80% of small and mediumsized<br />
(SME) construction firms want to see a<br />
licensing scheme introduced.<br />
And we are one of them...<br />
We welcome advancements within the sector and<br />
are proud members of the National Federation of<br />
Roofing Contractors (NFRC), Safe Contractor and<br />
CHAS, who all push for competency within the<br />
industry. After all, by increasing consumer<br />
protection and driving up quality, we can ultimately<br />
improve the image of the whole industry.<br />

7 WAYS ROOFERS CAN NETWORK &<br />
LEARN AT UK CONSTRUCTION WEEK<br />
As any busy roofing professional will admit, it can be difficult to justify time away from the job. But<br />
learning, networking and discovering are all essential to help keep on top of the latest industry<br />
insights, research, services and products. At UK Construction Week (UKCW), roofing<br />
professionals get the best of all worlds, with bespoke content on a selection of topical issues, but also<br />
exposure to a wider range of construction, regeneration and specialist technical learning. So if you’re<br />
still not signed up, here are seven reasons why you should attend the largest construction event of the<br />
year on 8-10th October, at Birmingham’s NEC.<br />
“This year UKCW is<br />
shining a spotlight on<br />
the serious changemakers<br />
in<br />
construction”<br />
1Discover new products New products are<br />
always being developed to meet different<br />
and emerging needs. Staying up to date<br />
with all the latest technology is essential to find<br />
the right product for the job. So, if you need to<br />
source new tools, or a new sustainable material,<br />
or discover new roofing products then look no<br />
further than UKCW. With over 10,000 products<br />
being showcased at the event, it’s the ideal<br />
marketplace to source your new product. With<br />
eight different sections ranging from build to<br />
timber and from surfaces to civils everything you<br />
need is right there under one roof.<br />
Build, sponsored by Easy-Trim, covers all aspects<br />
of roofing, cladding and insulation. Exhibitors<br />
include Quinn Building Products who will be<br />
discussing their concrete roof tiles, as well as<br />
their high performance PIR and EPS insulation.<br />
While Easy-Trim will be on hand to cover their<br />
breather membranes and a range of other roofing<br />
products.<br />
2That lucky encounter Year<br />
after year, visitors at<br />
UKCW say they won new<br />
work as a result of a planned<br />
meeting or a chance encounter<br />
at the show. People do<br />
business with people – and with<br />
35,000 visitors set to attend UKCW,<br />
that is a lot of potential leads. Meeting face<br />
to face is the most engaging way to do business<br />
and UKCW can facilitate that. If you have spotted<br />
a business that you want to connect with, contact<br />
them through the exhibitors’ portal and arrange<br />
the meeting in advance. 4,000 business meetings<br />
were booked by UKCW visitors prior to the show<br />
last year, and exhibitors reported that they had<br />
generated 70,000 new business leads at the<br />
event. To help with meetings, there’s a new<br />
business and networking lounge with free WIFI.<br />
3Genuine innovation, not<br />
another widget You<br />
could leave the future of<br />
the industry as a surprise. But<br />
where’s the business sense in<br />
that? Disruptors are now<br />
present in many different<br />
markets, so this year UKCW is<br />
shining a spotlight on the serious changemakers<br />
in construction. To aid the search, a new<br />
Innovation Zone has been established in<br />
partnership with the Construction Innovation Hub<br />
(the Hub).<br />
Another new addition for this year is the<br />
Innovation Station in partnership with On the<br />
Tools. This is a demonstration area specifically for<br />
power tools, with all the latest biscuit jointers and<br />
heavy-duty bench grinders from top trade brands<br />
in action. Visitors can pick up tips from the<br />
experts on how to get the most from their range,<br />
try out the latest products, and cut a deal with<br />
the manufacturers as show discounts will apply.<br />
4Your own personal industry MBA<br />
Condense your strategic business learning<br />
into one, two or three days of insights.<br />
UKCW brings together more than 300 expert<br />
speakers including Mark Farmer who is<br />

the details at a wide range of workshops. This year<br />
there will be more than 150 hours of CPD content<br />
available, including Dr Mike Wiseman from the<br />
British Board of Agrément, who will be covering<br />
‘Assessments of warm roofing systems’ CPD Hub<br />
2, in Hall 11. The programme will take on a<br />
different theme for each day of the show, tackling<br />
fire safety, health and wellbeing and sustainability.<br />
There are mini-theatres covering regeneration,<br />
MMC, digital construction, energy and HVAC,<br />
surfaces and materials, timber and the workplace.<br />
New for <strong>2019</strong>, the Working Well Together Theatre is<br />
covering a range of health and safety topics<br />
including, changes to HSE Mild Steel welding<br />
enforcement, pre-construction fire safety planning<br />
and design, keeping people safe while working at<br />
height, how to manage the issue of alcohol and<br />
drugs effectively in the workplace and mental<br />
health in the work place – an industry perspective.<br />
There’s a new Careers Centre too, offering<br />
workshops on career progression,<br />
apprenticeships, staff retention, diversity, career<br />
change and new talent.<br />
5Health and wellbeing Launching at UKCW<br />
this year, the Mind Your Head campaign is<br />
designed to promote mental wellbeing for<br />
those working in the construction industry, with<br />
particular focus on men who are at greater risk of<br />
suicide. It is a straight-talking, no-nonsense and<br />
accessible way to reach this target audience. As<br />
part of the campaign, Carwyn Lloyd Jones, the<br />
creator of the Tiny House at last year’s UKCW will<br />
be using his talents to create an artistic installation<br />
of swings which has a mental health focus.<br />
6A bit of myth busting on MMC Everyone<br />
knows that MMC are back in vogue, but<br />
what is the reality this time? MMC is a<br />
strong theme at this year’s UKCW. Full-scale<br />
builds will be erected onsite with live demos of<br />
MMC technology in action. Head to the MMC Hub<br />
for other digital demos and simulations too.<br />
Examples of the pre-manufactured structures at<br />
the show range from a modular care annex for the<br />
healthcare sector and a SIPS panel residential<br />
building, to a factory-finished modular bathroom<br />
pod for the high end hotel sector, and offsite<br />
solutions for the education sector.<br />
7Celebrations and a beer festival<br />
Everyone enjoys a good awards night and<br />
UKCW is no exception. The show hosts the<br />
UKCW Role Model of the year, the new Building<br />
Trades Awards with Fix Radio and the new UKCW<br />
Construction Awards. Plus, to encourage young<br />
people into construction, the iBuiltThis competition is<br />
back and the winners will be announced at UKCW.<br />
And if you’re not involved in the celebrations, just<br />
unwind each day with a beer, some street food<br />
and a spot of music. The Fischer bar is in Hall 11<br />
and the Rawlplug bar is in Hall 12. Don’t forget<br />

Business Talk<br />
TAKING A JAB & AVOIDING A VIRUS:<br />
PROTECT YOUR COMPUTERS<br />
Total Contractor takes a look at how you can protect your network of computers and<br />
sensitive information from viruses and other forms of attack...<br />
While computer viruses have been around since 1982, it surprises most that the first attacked an Apple computer. Put together by a 15-year-old who<br />
was fuelled by interest, not malice, it was spread by floppy disk (remember them?) and was designed to be a simple prank. Moving to the present,<br />
viruses now infect all types of computer-based device, but the majority are aimed at machines running Windows operating systems for one good<br />
reason – they are in the majority of computers and offer more rewards for the criminally minded.<br />
In recent years viruses and other forms of attack – trojans, phishing and so on – have caused havoc. From keyloggers (which secretly record keystrokes) to<br />
ransomware such as CryptoLocker (which encrypts data and demands a ransom to decrypt), firms are at risk from what is collectively known as ‘malware’.<br />
At the end of January (<strong>2019</strong>), Kwik Fit confirmed that its network had been infected and its systems knocked offline for a few days. The company was forced to<br />
cancel bookings and customers vented their anger on social media.<br />
While the larger firm will – should – have processes in place to protect systems, what can an independent do to stay virus free? The answer is to follow a 10-<br />
step guide.<br />
Ten ways to stay virus free:<br />
1Install protection Dealing with virus and<br />
other threats is an unwelcome distraction<br />
that takes time. The first sign might be a<br />
computer running slowly or behaving peculiarly.<br />
While some viruses are irritating others are a<br />
serious threat. No form of inoculation can ever be<br />
perfect but installing an anti-virus package from<br />
a reputable software vendor is an obvious but<br />
crucial step to take. Some firms charge but free<br />
versions are available from the likes of Avast and<br />
Microsoft (built into Windows 10 but earlier<br />
versions need a download).<br />
2Update and scan The key to success with<br />
anti-virus is to keep the application<br />
updated and to regularly scan computers<br />
for threats. A computer virus is no different from<br />
that which can infect a living organism; over time<br />
it morphs as the designers seek to work around<br />
the protections that security software puts in<br />
place.<br />
Regularly scanning a computer or network for<br />
downloaded or installed threats is an absolute<br />
must. It ought to be done daily but should be<br />
carried out at least once a week. Scans are<br />
intensive and can cause a system to grind to a<br />
halt so scans should be timed for an off-peak<br />
moment which, if computers are turned off at<br />
night, is not then. Similarly, ensure that the<br />
computer cannot go into sleep-mode.<br />
Remember – anti-virus is only as good as the<br />
database of threats it holds, so it should be kept<br />
updated.<br />
3Update the operating system Windows,<br />
Mac or any other system you might be<br />
running needs regular updating. These<br />
systems are hugely complex and run to millions of<br />
lines of code and are riddled with vulnerabilities<br />
which are often being found; it’s the reason why<br />
developers perpetually issue software updates<br />
and fix security issues.<br />
4Your network is at risk One of the biggest<br />
mistakes a user can make is to fail to<br />
secure their network. When computers<br />
were offline, and data was moved by floppy disk,<br />
the threat was minimal. Now online devices are<br />
permanently under threat. The problem is<br />
exacerbated when devices – modem, router,<br />
computer, printer or any other connected item –<br />
are left with both default names and default<br />
passwords. Any hacker worth their salt will see<br />
what is connected and will know how to attack<br />
what they’ve found.<br />
It is therefore critical to change the device name<br />
and password as soon as it’s connected. WIFI<br />
products should, once set up, not broadcast their<br />
existence. This means turning off what is called<br />
the ‘SSID’. Passwords should be strong – select<br />
at the minimum WPA or WPA2 encryption.<br />
If visitors are to connect to your network, ensure<br />
that they’re using a router with a guest – discrete<br />
– network which allows access to the web and<br />
nothing else.<br />
22 TC SEPTEMBER <strong>2019</strong>
5Strong passwords Another huge risk for<br />
anyone with a connected device, especially<br />
in today’s online world and the<br />
proliferation of online banks and the move to<br />
paperless interaction with HMRC, is their<br />
password.<br />
It is essential that the same passwords are never<br />
reused. It’s entirely understandable that we reuse<br />
passwords or variants of them in combination<br />
with the same email address or username. But<br />
those that do and who are unfortunate enough to<br />
have been compromised will find that any<br />
account they have is also at risk.<br />
As to how to create a strong password, avoid<br />
names, places, pets or dates of birth. Use a long<br />
mixture of upper case, lower case, numbers, and<br />
symbols. Search for an online password<br />
generator.<br />
Lastly, change passwords frequently and<br />
especially when any member of staff leaves.<br />
6Put sites off limits Human error is the<br />
biggest cause of security vulnerabilities so<br />
it’s important to ingrain caution within<br />
staff, ideally by a policy that covers what they can<br />
and cannot do online. This means detailing which<br />
websites can be visited, that no software is to be<br />
downloaded or installed (it could be pirated and<br />
compromised), and that email with attachments<br />
should be quarantined and scanned. Again,<br />
having decent and current anti-virus software in<br />
place will mean that anything that is downloaded<br />
will be scanned before being opened or run.<br />
7Be private Remembering that human error<br />
is one of the biggest risks, staff should be<br />
made aware of ‘social engineering’ and that<br />
a plausible caller can get someone to give away<br />
whatever is held precious. It’s this that is behind<br />
authorised push payment fraud – where a caller<br />
tells an individual that their accounts are at risk<br />
and that they should move their monies to a new<br />
and ‘safe’ account. The harsh reality is that these<br />
“At the end of the day, computers can and do get compromised so planning for disaster should be part of business housekeeping”<br />
individuals have sent their monies to the fraudster<br />
and so will get little help from the banks.<br />
Never give any private information out without<br />
being 100 percent certain of the person or<br />
organisation asking. Be careful with what the<br />
business (and individuals) post online or via<br />
social media. Apply the same principles to paperbased<br />
information. All someone needs to<br />
compromise your systems is enough of the right<br />
bits of information.<br />
As the evidence shows, using social engineering<br />
is much easier than expending effort on hacking<br />
systems.<br />
8Public WIFI It’s so tempting to want to be<br />
online at all times and it’s just as tempting<br />
to use public, or open, WIFI networks.<br />
Partly because mobile data may be unavailable<br />
but also because it may be free. The reason is<br />
very simple – just as you can connect a laptop to<br />
a free WIFI hotspot, so can anyone else. If they’re<br />
criminally minded, they can access your data and<br />
plant viruses.<br />
9Staff devices Another threat to counter is<br />
one from staff who connect their own<br />
devices such as phones, to company<br />
network or their computer. Thought should be<br />
given to limiting access to the firm’s WIFI or<br />
physical network. The same applies to USB<br />
devices – it’s a well-known trick for a fraudster<br />
to drop a USB stick in a car park for an individual<br />
to pick up and connect to their computer to see<br />
what’s on it.<br />
up At the end of the day,<br />
computers can and do get<br />
10Back<br />
compromised so planning for<br />
disaster should be part of business<br />
housekeeping. Backing up data onto several<br />
separate devices, regularly (at least once a day)<br />
and keeping them off site at different locations is<br />
critical. Consider a combination of methods such<br />
as external hard drives, a computer elsewhere<br />
and cloud storage services such as Dropbox.<br />
Remember to encrypt devices in case they fall<br />
into the wrong hands.<br />
To end<br />
Assuming that you are unlikely to be attacked is a<br />
foolish stance and one that will lead to disaster.<br />
All it takes is a lucky find by a hacker combined<br />
with easy access for the rest to be history.<br />

Insurance: Project Policies<br />
THE PROBLEM WITH PROJECT<br />
POLICIES: ARE YOU COVERED?<br />
By Ian Hollingworth, Technical Claims and Relationship Manager, ECIC.<br />
The High Court’s decision last year that a<br />
roofing firm that caused a fire at a high<br />
school in London was not protected by a<br />
project policy has raised some serious questions<br />
over the worth of these types of insurance<br />
policies.<br />
Traditionally, employers on larger construction<br />
projects take out a project policy to cover damage<br />
to the existing structure and possibly the contract<br />
works being undertaken by the sub-contractors<br />
appointed to work on site.<br />
The contractual chain<br />
A project policy would usually provide protection<br />
to named contractors and sometimes all<br />
contractors in the contractual chain, in the event<br />
of a fire or some other damage caused by<br />
contract workers on site.<br />
The project policy insurer would simply cover the<br />
loss rather than each sub-contractor going to<br />
their own insurers to recover the cost of their own<br />
damaged contract works. This means lengthy and<br />
costly litigation between sub-contractors can be<br />
avoided and ensures the property and works are<br />
adequately covered, preventing any delays in the<br />
completion of the construction.<br />
However, in Haberdashers’ Aske’s Federation<br />
Trust Ltd v Lakehouse Contracts Ltd and others<br />
[2018] EWHC 558 (TCC), the High Court found<br />
roofing firm CPR wasn’t protected by the project<br />
policy because the terms of the sub-contract<br />
required that they should maintain their own<br />
insurance.<br />
That’s not unusual in itself. Usually a<br />
construction contract would contain an insuring<br />
clause requiring the individual sub-contractor to<br />
take out insurance to cover their own contract<br />
works along with Employers Liability and Public<br />
Liability. This is even if there is a<br />
project policy in place.<br />
The key difference with this case<br />
was that the project policy<br />
insurer dealt with the property<br />
loss, but then sought to recover<br />
their outlay from the contractor that<br />
caused the loss.<br />
“It’s essential,<br />
therefore, that<br />
contractors are aware<br />
that a project policy<br />
may no longer provide<br />
the catchall cover they<br />
have previously relied<br />
on”<br />
This was very unusual as a project policy is<br />
usually taken out in joint names – the<br />
policyholder and all sub-contractors. As such the<br />
project policy insurer could not seek a recovery as<br />
essentially all sub-contractors would be<br />
considered a policyholder and covered under the<br />
policy.<br />
Not named at commencement<br />
The Court allowed the project insurer to recover<br />
the loss from the sub-contractor on the basis of<br />
two key facts: the main contract had required the<br />
sub-contractor to take out their own insurance;<br />
and the sub-contractor was not named at the<br />
commencement of the construction project and<br />
therefore not factored into the cover by the project<br />
policy insurer when the policy was taken out.<br />
The contractor in this case was due to appeal the<br />
High Court’s decision in early <strong>2019</strong> but instead<br />
Left: Ian Hollingworth, Technical Claims and<br />
Relationship Manager, ECIC.<br />
settled out of court, prior to the<br />
appeal hearing.<br />
This ruling has really called into<br />
question the effectiveness of project<br />
insurance. Roofing contractors and subcontractors<br />
may no longer rely upon a project<br />
insurer to pick up a loss in the event of damage<br />
they have caused.<br />
It’s essential, therefore, that contractors are<br />
aware that a project policy may no longer provide<br />
the catchall cover they have previously relied on<br />
and should try to take proactive steps to seek<br />
confirmation of any cover available under a<br />
project policy at the pre-commencement stage.<br />
Working with their insurance brokers, roofing<br />
contractors would be well-advised to take a fresh<br />
look at their cover to ensure they are adequately<br />
insured for their potential liabilities. In most<br />
cases they may need their own Contractors All<br />
Risks insurance in addition to public liability<br />
insurance to ensure they have the right levels of<br />
cover in place before starting work on a major<br />
contract.<br />
Contractors All Risks insurance provides cover for<br />
physical loss or damage to contract works during<br />
the course of construction and will often be<br />
offered with a range of extensions to provide more<br />
bespoke cover. Public liability insurance provides<br />
cover in the event of damage or personal injury to<br />
third parties.<br />

NFRC Tech Talk<br />
SAFE2TORCH FOCUS: LPG CYLINDERS<br />
Gary Walpole, NFRC’s Health, Safety and Environment Officer, explains some of the main<br />
points that installers need to consider when carrying out hot works according to Safe2Torch<br />
principles. In part one, he focuses on handling and storing LPG cylinders.<br />
In July 2017, the NFRC launched its Safe2Torch guidance for specifiers of waterproofing systems to recognise fire risks at the design phase and replace<br />
these details with a torch-free alternative. We wanted to encourage the specifier to consider the whole process from design and planning through to<br />
the installation of the actual work. The next stage of the Safe2Torch campaign is to support the contractors working with gas torches by providing them<br />
with a Safe2Torch training module, which is supported by the Safe2Torch Safe System of Work and a pictorial checklist. This is available from<br />
www.nfrc.co.uk/safe2torch. So, what are the main points that contractors involved in hot works need to consider in order to ensure safety? Below are<br />
some key points from the Safe System of Work.<br />
Handling LPG cylinders<br />
When moving or handling LPG cylinders, it is<br />
important to bear in mind the following:<br />
1. Plan the lift: an LPG cylinder should always<br />
be upright when lifted to the place of work.<br />
2. Lift properly: always use the proper lifting<br />
technique when moving LPG cylinders.<br />
3. Know your limits: be aware of your personal<br />
lifting limits.<br />
4. Wear gloves: use suitable gloves to ensure<br />
you have a firm grip when LPG cylinders are wet<br />
and slippery.<br />
5. Never roll: never roll LPG cylinders on their<br />
side, throw them or drop them.<br />
6. Use the correct trolley: move LPG cylinders<br />
with a purpose-made trolley that has a chain<br />
attached to secure the cylinder.<br />
7. Never lift by the bottle cap – do not use the<br />
LPG bottle cap, valve or shroud to lift the cylinder.<br />
8. Test the ‘empty’ cylinder: it may still contain<br />
LPG; rock it to feel the movement of the liquid.<br />
9. Never open valve of an unconnected<br />
cylinder: do not open the valve of an<br />
unconnected LPG cylinder as there is still likely to<br />
be some LPG left inside (even on cylinders that<br />
appear empty)<br />
“Never search for leaks<br />
with a naked flame”<br />
Storing LPG cylinders<br />
It is important that LPG cylinders are stored in the<br />
upright position and removed from the workplace<br />
when not in use, and cylinders should be stored<br />
in a lockable gas cage when not in use.<br />
1. Keep upright: store and use the LPG cylinder<br />
in an upright position.<br />
2. Keep well ventilated: store LPG cylinders in<br />
well ventilated places.<br />
3. Keep away from heat: ensure LPG cylinders<br />
are stored away from heat and ignition sources.<br />
4. Keep Propane outside: avoid storing Propane<br />
LPG cylinders indoors.<br />
5. Keep away from access points: ensure LPG<br />
cylinders are stored outdoors, away from building<br />
entry/exit points.<br />
6. Isolate from other material: keep LPG<br />
cylinders away from any corrosive, toxic or<br />
oxidant material.<br />
Using LPG cylinders<br />
The greatest hazard when working with LPG is<br />
that when mixed with air, it can burn or explode if<br />
there is a source of ignition. LPG containers are<br />
liable to explode if they are involved in a fire.<br />
1. Treat with care: when using an LPG cylinder,<br />
you should always treat it with care, keep it<br />
upright and read the instructions and labels<br />
provided.<br />
2. Return empty cylinders: ensure you return<br />
the LPG cylinder when it’s empty or not in use for<br />
long periods.<br />
3. Keep clean: remember to keep your LPG<br />
appliances clean and have them serviced<br />
regularly.<br />
4. Avoid heat: do not subject the LPG cylinder to<br />
heat as this could increase the pressure inside<br />
and exceed the safe limit. This applies to empty<br />
cylinders as it does to full ones.<br />
5. Do not disconnect the regulator: do not try to<br />
disconnect or unscrew a regulator from any<br />
cylinder if the flame doesn’t go out.<br />
6. Use your senses: leaks may be identified by<br />
smell, noise or an approved leak detection<br />
solution or leak detector.<br />

FORD PLANS TO GET MOTORING –<br />
BUT WHICH ROUTE WILL HE TAKE?<br />
At 26, Matthew Ford has won one of the industry’s top awards, the BMI Apprentice of the<br />
Year <strong>2019</strong> in pitched roofing. So what now for this young roofer?<br />
Afew months on from winning the pitched<br />
roofing title at the BMI Apprentice of the<br />
Year competition, Matthew Ford is still<br />
keeping his head down, weighing up his next<br />
move and doing his best with his job, while<br />
attending Leeds College of Building.<br />
He works for Incommunities, the Bradford-based<br />
social housing provider, as one of eight roofers<br />
working in teams of two. His main work is<br />
carrying out repairs and approving the work of<br />
roofing contractors, which he says can be quite<br />
challenging.<br />
“I can’t pass a roof that isn’t as good as I would<br />
put on,” he said, taking pains to point out that the<br />
roof on which he has been photographed is not<br />

“I can’t pass a roof that<br />
isn’t as good as I would<br />
put on”<br />
his handiwork, but one that he has yet to inspect<br />
and approve.<br />
Standards mean a lot to Matthew and one thing<br />
that he knows for certain is that he wants to help<br />
improve the image of roofing as a trade and to<br />
raise professional standards. He is, for instance,<br />
taking part in a trial for RoofCERT, the<br />
accreditation scheme devised by the NFRC and<br />
CITB, as a result of his award and a conversation<br />
with Simon Dixon, Training Manager at the NFRC.<br />
“The idea is it’ll be like Gas Safe and let people<br />
know who they can trust, and it’ll eradicate the<br />
cowboys who just rock up and offer to do the<br />
roof,” he explained.<br />
“RoofCERT will shape the way that roofers extend<br />
their skills in a scheme that continuously checks<br />
that they’re still complying to the relevant<br />
standards and regulations.”<br />
Confidence boost<br />
Matthew recognises that he would never have<br />
thought of becoming involved with projects such<br />
as this before he took part in the competition.<br />
“It boosted my confidence no end. The<br />
competition went into areas that just aren’t<br />
covered in college and it was never just about<br />
simply putting on a roof. We learnt other skills<br />
about presentation, relating to the clients and<br />
looking at business plans.<br />
“These are things that I use every day. I have to<br />
meet eight to ten people every day, tell them what<br />
repairs are necessary and why and then, if further<br />
work is needed, produce a report for my manager<br />
to explain why,” he explained.<br />
‘The Fossil’ plans for the future<br />
At 26, Matthew realised that he was quite a bit<br />
older than the other apprentices entering the<br />
Apprentice of the Year competition. In fact, the<br />
other students make sure he never forgets by<br />
nicknaming him ‘The Fossil’. But Chris<br />

Above left: Matthew Ford wants to complete his Year Three modules and take his education as far as it can carry him. Right: Tony Thompson, Training Manager at Incommunities.<br />
Messenger, his tutor at Leeds College of Building,<br />
and Jay Webster, last year’s winner, encouraged<br />
him to go in for it.<br />
“Jay‘s doing his Level Three at the college and he<br />
told us what to expect and how it was a lot to do<br />
with business planning, not just putting on roofs.<br />
We’re good friends now and talk quite often about<br />
the roofing business,” Matthew recalled.<br />
The competition was open to all roofing<br />
apprentices who were enrolled with one of BMI’s<br />
participating colleges or training groups, with the<br />
finalists competing over two days that comprised<br />
a series of presentations and assignments. These<br />
examined every facet of running your own roofing<br />
business – including business planning, technical<br />
skills and presentation. In particular, each<br />
apprentice had to make their own, five-minute<br />
presentation to the judges at the end describing<br />
their motivation and future objectives in roofing.<br />
‘Hard work and sacrifice’<br />
For Matthew, those ‘future objectives’ have yet to<br />
be defined because, having completed his Year<br />
Two course – six months ahead of schedule – he<br />
now wants to complete his Year Three modules<br />
and take his education as far as it can carry him.<br />
His employer is also more than keen to assist. It<br />
is a matter of policy says Training Manager Tony<br />
Thompson. The policy of Incommunities is to train<br />
its 1,000 strong workforce so they have all the<br />
qualifications they need to reach the highest<br />
ranks of the business.<br />
“We celebrate success and this competition helps<br />
us do just that. Apprenticeships require hard work<br />
and sacrifice – they’re not highly paid – and it’s<br />
right to reward that,” he explained.<br />
“We know that university isn’t the right route for<br />
everybody and apprenticeships can offer an<br />
education that can take you right up to<br />
management and degree level. This competition<br />
raises the profile of apprentices and of roofing so<br />
we’re very happy to take part.”<br />
Incommunities is a large employer with 1,000<br />
staff and manages 22,000 homes, mainly in<br />
Bradford but also in Wakefield, Kirklees,<br />
Rotherham and Sheffield. So, the opportunities it<br />
can offer persuaded Matthew to change jobs. Up<br />
until three years ago he worked with his father<br />
Stephen in his roofing business but he wanted<br />
qualifications, a steady job so he could get a<br />
mortgage and better career prospects.<br />
“I am ambitious and now, after winning the<br />
competition, I can see that I could progress into<br />
management, though that wouldn’t be roofing as<br />
such but would be more like asset management,<br />
being a project leader,” explained Matthew.<br />
“Apprenticeships<br />
require hard work and<br />
sacrifice – they’re not<br />
highly paid – and it’s<br />
right to reward that”<br />
“I would also like to look at wider roles in bodies<br />
like the NFRC. I think entering the competition<br />
means I’ve come out as a ‘well-rounded package’<br />
with all the skills to run a business.”<br />
Matthew also met Ceiran Peel-Price, another<br />
former finalist, who now runs his own business –<br />
a direction which Matthew is also considering.<br />
“The competition definitely gives you the idea<br />
that you could set up your own business and<br />
Bradford would be ideal. You know that you could<br />
make a difference and show how a roof should be<br />
laid,” he concluded.<br />
Whether Matthew decides to go down the<br />
managerial route or strike out on his own, it is<br />
plain to see that he is determined to make his<br />
mark on this industry and that this will not be the<br />
last time we hear of him.<br />

Graded Battens<br />
6 STEPS TO BATTEN SUCCESS<br />
Jenni Forrest, Quality Manager for JB Red at Marley, answers contractor queries about<br />
roofing battens.<br />
Roofing battens are one of the most important parts of a pitched roof structure, acting as a<br />
structural and load-bearing element. As well as supporting the dead weight of tiles and the<br />
imposed wind loads, BS 5534 graded roofing battens can also be used as a secure foothold<br />
during installation. That’s why checking the quality and compliance of the roofing battens you are using<br />
is so important.<br />
Below we answer some common contractor queries about<br />
choosing and installing roofing battens:<br />
JB Red battens being loaded into the treatment vessel.<br />
1What batten defects are allowed under<br />
BS 5534? As a natural material, timber<br />
battens will obviously have varied<br />
characteristics but BS 5534 is very strict about<br />
what is and isn’t allowed, and our machine<br />
grading process scans battens by the millimetre<br />
to make sure they meet the requirements of the<br />
standard.<br />
Some knots are allowed, depending on their size<br />
and position. If a knot appears on both sides of<br />
the face, the sum of the knot on both faces must<br />
not exceed the width of the batten. A knot<br />
appearing on both sides of the batten which does<br />
not appear on the face is only deemed<br />
permissible if the knot on either side is one-fifth<br />
of the depth or less.<br />
BS 5534 also allows for a missing corner on the<br />
batten, otherwise known as wane. However, it is<br />
only permitted on one axis and should not exceed<br />
one-third of the dimension of each of the faces<br />
on which it occurs.<br />
For a full list of permissible defects, we have put<br />
together a free pocket checklist to help<br />
contractors ensure they are using quality,<br />
compliant battens. For your free copy, email<br />
info@marley.co.uk.<br />
If you have any doubts about a possible defect,<br />
check with the manufacturer before you use the<br />
batten.<br />
2Do battens have to be completely<br />
straight? Battens need to be straight, so<br />
BS 5534 sets a tolerance on distortion.<br />
Bow, spring or twist should each not be greater<br />
than 5mm, measured over a length of 1.2m at a<br />
reference moisture content of 20%. If your batten<br />
is bowed more than this, then do not use it and<br />
check with the manufacturer.<br />
Battens cut from sideboards are less likely to<br />
distort which is why JB Red battens are only<br />
manufactured from kiln dried sideboards.<br />
3Aren’t all graded battens the same? If<br />
you have two battens from different<br />
manufacturers, both graded to BS 5534,<br />
many people would assume that they are the<br />
same. However, this may not be the case and just<br />
like other roofing products, there can be<br />
significant variations in quality and performance.<br />
Indeed, it is surprising how many differences<br />
there can be between similar looking roofing<br />
battens – from the way they are graded, through<br />
to the type of timber they are made from, the<br />
quality processes they go through and the<br />
preservatives they are treated with.<br />
To make sure roofing contractors know how to<br />
choose the best quality battens, at Marley we are<br />
carrying out an education campaign to ensure our<br />
customers know how to spot the differences<br />
between graded battens. This includes the launch<br />
of our new batten CPD which our sales teams will<br />
be delivering to contractors across the country, as<br />
well as the free pocket checklist.<br />
4I’ve been told that all coloured battens<br />
are BS 5534 compliant, is that true? No.<br />
The issue of batten colour has caused<br />
some confusion. Whilst the distinctive red colour<br />
of our JB Red battens along with other coloured<br />
battens from reputable manufacturers does give<br />
peace of mind that you are using a BS 5534<br />
compliant batten, this is not necessarily the case<br />
for all battens. Please don’t assume that just<br />
because it is coloured that a batten meets the<br />
required British Standard. It must also have the<br />
correct stamps and supporting documentation.<br />
5Do counter-battens need to be graded<br />
to BS 5534? There has been some<br />
confusion about whether-counter battens<br />
also need to be graded to BS 5534. Counterbattens<br />
do not need grading, providing they are<br />
fully supported and are fit for their intended<br />
purpose. The dimensions of counter-battens<br />
should be sufficient to provide a ventilation gap<br />
for close fitting roof coverings as recommended in<br />
BS 5250 and/or to provide a drainage path<br />
beneath the battens.<br />

battens, request your free battens CPD training<br />

An Inspector Calls<br />
THE VERY SERIOUS CONSEQUENCES<br />
OF DELAMINATION: CHOOSE WISELY<br />
In our regular monthly column – ‘An Inspector Calls’ – Total Contractor has teamed up<br />
with the experts at BMI UK & Ireland, leaders in pitched and flat roofing solutions, to<br />
help you achieve roofing success and avoid the common pitfalls that can often cost you<br />
both time and money.<br />
This month the Inspector lifts the lid on clay<br />
tile delamination and its consequences.<br />
The quality of raw materials and the<br />
manufacturing process largely determine<br />
how prone clay roof tiles are to the defects<br />
of surface spalling and delamination – the bane<br />
of clay roof tiles. Lamination is where you have<br />
weakly connected layers of material within the<br />
body of the clay. When those tile layers begin to<br />
separate, you have delamination. It is found in all<br />
clay products but is more prevalent in poorly<br />
mixed and/ or sourced raw materials.<br />
Avoiding delamination is a solid argument for<br />
choosing both high quality clay and<br />
manufacturing credentials when selecting a clay<br />
plain tile for the roof. After all, a clay plain tile<br />
roof – at 60 tiles per m², laid at a broken bond<br />
and double lap – is the one of the most<br />
expensive and complex systems a customer<br />
may choose for a roof.<br />
Why then skimp on the materials?<br />
Below: delamination Don’t be the ‘spall guy’ by removing moss from the tile surface as the consequences can be catastrophic for the roof.<br />

An Inspector Calls<br />
Above and below, delamination: Flaky situation – a complete re-roof is not far away...<br />
“The removal of the<br />
moss had helped drag<br />
away the surface<br />
material of the tile”<br />
Flaky tiles<br />
The death knell for the roof is if and when tiles do<br />
start to delaminate. It occurs when water,<br />
absorbed into the slate or tile during the winter,<br />
freezes and expands, causing the fired clay<br />
mineral layers to separate and ultimately flake<br />
off. If you can see tiles delaminating on the<br />
surface, then chances are that under the lap –<br />
where the surface is darker and damper – you<br />
will find even more.<br />
At best and at least, it is a partial strip and reroof<br />
as, at this point, the delamination is only<br />
going one way – and that is towards complete<br />
roof failure. Not to mention that the debris falling<br />
down the roof will be obstructing the free flow of<br />
water off it.<br />
Don’t assist delamination…<br />
The thing we absolutely<br />
should not do when the<br />
first signs of<br />
delamination<br />
appear in the roof<br />
is help it along!<br />
The images show<br />
an old clay roof<br />
that had been<br />
beleaguered with<br />
moss and dirt.<br />
As the moss fell away, it<br />
was blocking the gutters and –<br />
as nobody likes having to get up there<br />
to clean them – a contractor was called in to deal<br />
with the problem. A quick wash and a brush later<br />
the moss was gone and the roof looking very<br />
clean: yet very, very broken. The removal of the<br />
moss had helped drag away the surface material<br />
of the tile, and now the failure of the roof covering<br />
was well underway.<br />
Care should be taken when<br />
making any alterations to<br />
the surface of the<br />
roof covering,<br />
especially when<br />
dealing with<br />
an aging roof.<br />
Often<br />
attempts to<br />
carry out<br />
superficial<br />
repairs can<br />
result in bigger<br />
problems.<br />
The main issue here was that<br />
the customer was not made aware of the<br />
risk to the roof covering and what started out as a<br />
maintenance job turned into the prospect of a reroof.<br />
One could of course argue that the damage<br />
was already done beneath, and the greater work<br />
would need to happen at some point anyway, yet<br />
forewarned is forearmed.<br />

Marketing Talk<br />
THE SIMPLE LIFE: HOW A SIMPLIFIED<br />
OFFERING CAN SPELL SUCCESS<br />
Richard Kendrick, Marketing Manager for SIG Roofing, explores why it sometimes pays<br />
to keep it simple…<br />
Like much of the construction industry, the<br />
roofing sector is an incredibly crowded<br />
marketplace with specialists of all sizes<br />
jostling for new business. Indeed, roofing start-ups<br />
today are entering an industry which has 63,000<br />
other professionals already plying their trade.<br />
The outlook is particularly tough for smaller<br />
roofing enterprises. Not only do they face stiff<br />
competition within the market, but must also<br />
weather a sometimes uncertain economic climate<br />
– particularly impactful on the so-called ‘one<br />
man bands’, which make up a significant<br />
proportion of the construction industry.<br />
So, when confronted with such a challenging<br />
landscape, how can roofers stand apart from<br />
their competitors and secure those all-important<br />
new business wins?<br />
Roofing 101<br />
Like any business, a fundamental rule to<br />
remember for your roofing business is – it’s better<br />
to do one thing exceptionally, than a number of<br />
things poorly. While it might be tempting to<br />
change-up your offering, providing an array of<br />
services and add-ons that your competitors don’t,<br />
this could leave you stretched and unable to<br />
complete jobs on time or to a high-standard.<br />
At SIG Roofing, we advise roofers to carry out an<br />
honest assessment of their offering before looking<br />
to expand it. Do you have the right resources,<br />
skillset or experience to be able to offer the<br />
additional services successfully? Similarly, take a<br />
look at your existing customer base and qualify<br />
whether there is an appetite for the add-ons<br />
you’re looking to incorporate into your business.<br />
While diversifying your service offering may make<br />
you stand out from the crowd, there are a number<br />
It might be a challenging marketplace right now, but there<br />
are plenty of opportunities for you to still win new customers.<br />
of simple considerations, which, if applied<br />
correctly, can make a real difference to your<br />
ability to attract new business.<br />
Be professional<br />
Did you know that referrals and word-of-mouth<br />
from satisfied customers generate upwards of 35%<br />
of all new business traffic for roofing specialists?<br />
It sounds like a cliché, but first impressions do<br />
count, so make sure when meeting with<br />
prospective customers you turn up on time and<br />
have a number of customer testimonials on hand.<br />
Similarly, after your initial meeting, it’s important<br />
that you follow up promptly with a quotation – the<br />
sooner that goes across, the sooner you can<br />
(hopefully) get the job secured.<br />
Stay connected<br />
We covered this off in our last advice piece, but<br />
it’s worth reiterating – the modern roofer needs<br />
to have an online presence to stand a chance of<br />
securing new business.<br />
For social media, we recommend both LinkedIn<br />
(as a way of growing your presence within the<br />
industry) and Facebook. Roofing is such a visual<br />
business, so your Facebook page represents a<br />
fantastic opportunity to showcase eye-catching<br />
examples of your latest work. This links back to<br />
the power of the testimonial – new customers are<br />
more likely to want to work with you if you’ve<br />
posted proven examples of your fantastic work.<br />
When it comes to your website, treat this as an<br />
extension of your sales brochure, so a great<br />
platform through which to show off examples of<br />
your work. What’s more, the website doesn’t need<br />
to be complex – far from it. Indeed, the most<br />
effective roofing websites enable customers to<br />
find what they need in a matter of clicks. Make<br />
sure that your contact details are easy to find, too<br />
– there’s nothing more frustrating for a potential<br />
customer than being unable to find a phone<br />
number or email address.<br />
Be your brand<br />
Finally, remember that there are several ‘free<br />
advertising’ resources at your fingertips. Your<br />
vehicle, for example, is likely to be seen by<br />
hundreds of potential customers throughout a<br />
working day, so consider including your signage /<br />
contact details on the side.<br />
Similarly, when you or your employees are out<br />
and about, it’s a good idea to wear branded<br />
clothing – embroidered polo shirts, hoodies and<br />
fleeces not only look professional, they are<br />
inexpensive to acquire and are another way of<br />
making your brand visible.<br />
It might be a challenging marketplace right now, but<br />
there are plenty of opportunities for you to still win<br />
new customers. So, when considering your new<br />
business strategy, have a think about the smaller<br />
steps you can take to further boost your offering –<br />
sometimes keeping it simple really does pay off!<br />

Q&A: Metal Rainwater Systems<br />
“ALUMINIUM AS A METAL SYSTEM<br />
HAS A FANTASTIC FUTURE”<br />
Total Contractor magazine talks common installation mistakes, project pressures for<br />
installers and so much more with Karen Moulds, Marketing Manager at ARP.<br />
TC: Please tell us a bit about ARP and its<br />
offering for contractors and installers…<br />
KM: ARP has been established for over 30 years,<br />
providing metal roofline and rainwater products to<br />
contractors and installers, offering a full range of<br />
quality roofline and rainwater systems in both<br />
aluminium and cast iron, at a competitive price<br />
with short lead times.<br />
In addition, having a network of Sales Managers<br />
that cover the whole of the UK enables us to<br />
provide a full customer experience offering full<br />
site assistance.<br />
TC: You offer both aluminium and castiron<br />
options, what do you feel are the<br />
benefits of these materials for both the<br />
installer and the building owner?<br />
KM: We like to work with our customers to ensure<br />
that the products and services we supply are<br />
suited for their needs. By working together we can<br />
understand the particular challenges they are<br />
facing and be in the best place to help solve<br />
them.<br />
Our products are designed to be fit for purpose<br />
from the day they are installed for many decades<br />
to come, with little or no maintenance.<br />
So for the installer, a high quality product that is<br />
easy to fit, which maintains its appearance, but<br />
is also durable and long lasting.<br />
For the property owner – they have peace of mind<br />
they have a sustainable rainwater system and<br />
decades of rainwater protection with little or no<br />
maintenance. Both aluminium and cast iron are<br />
made from an increasing element of recycled<br />
material, which can also be recycled at the end of<br />
its useful life, providing a sustainable cradle to<br />
cradle product that will not end up as landfill<br />
when the product is finished with.<br />
Both aluminium and castiron<br />
systems have long life<br />
spans, much longer than<br />
other materials such as<br />
upvc.<br />
Aluminium is a lightweight<br />
malleable metal, which is<br />
strong and durable, does not rust or<br />
corrode and is non-combustible, so lends<br />
itself to architectural elements such as fascias<br />
and soffits, wall cappings and copings, etc.<br />
Cast Iron rainwater systems are often used for<br />
heritage, conservation or listed properties, and<br />
have an expected lifespan of 100 years, if<br />
properly maintained.<br />
TC: The perception is sometimes that<br />
metal systems are only used on higher<br />
end projects, is this the case?<br />
KM: No, not now – it may well have been.<br />
Aluminium was considered much more of a niche<br />
product, however, our experience tells us that it is<br />
a much more regularly used material because of<br />
all the benefits aluminium offers now as a longterm<br />
solution.<br />
We are working hard to change this perception<br />
as the cost versus the durability of metal<br />
systems can mean that it works out to be far<br />
more cost effective to specify and fit a metal<br />
system than plastic; metal systems can last in<br />
excess of 60 years, whereas plastic may only<br />
last for 20-30 years.<br />
TC: Can you tell us a bit about your<br />
Mustang and Alstream approved installer<br />
schemes…<br />
Left: Glenshee project, Legacy Aluminium<br />
Gutter and Colonnade Downpipes<br />
KM: ARP’s Mustang®<br />
system is the market<br />
leader when it comes to<br />
seamless aluminium<br />
guttering systems, where it<br />
is extruded quickly and easily<br />
from an Ironman TM machine at<br />
the site of the installation. As all the<br />
preparation work is done at ground level, this<br />
system minimises the length of time installers<br />
spend working at height. Gutters can be run out<br />
in lengths of up to 30 metres and because there<br />
are no joints, it will not leak. Made from 0.9mm<br />
aluminium coil, this is the only aluminium<br />
seamless gutter system which is British Board of<br />
Agrément accredited. We have a national network<br />
of Mustang® Approved installers which are fully<br />
trained by us, but are also inspected regularly to<br />
maintain approved status. This means that the<br />

Q&A: Metal Rainwater Systems<br />
fixtures and fittings are added whilst safely on the<br />
ground – therefore the only work at height is<br />
offering the gutter up to the roofline to actually fit<br />
it into place.<br />
The coil means that the installer may have up to<br />
130 metres of gutter in his van, the machine<br />
allows him to only extrude the lengths he needs to<br />
complete the job therefore there’s no waste.<br />
TC: What are some of the most common<br />
mistakes that installers make when it<br />
comes to installing rainwater systems?<br />
KM: One of the most common mistakes made<br />
when installing rainwater systems is the siting of<br />
the gutter itself. If the gutter is positioned too<br />
close to the roofline, the water can overshoot the<br />
gutter and be more liable to get damaged in snow<br />
conditions (geographically dependant). If it is<br />
positioned too low, rainwater would simply<br />
bypass the gutter and be completely ineffective.<br />
We provide full installation instructions and a<br />
detailed view of where the gutter should be<br />
placed for optimum performance.<br />
Other instances we are mindful of is the correct<br />
use and type of silicone and having the right<br />
tools/blades to make cuts on site.<br />

installers – what sort of lead times can<br />

are more intense and installers want products<br />

EDEN – REWRITING THE BOOK<br />
ON CLAY PANTILES<br />
Marley is rewriting the book on clay<br />
pantiles with a ground-breaking new<br />
traditional pantile that incorporates<br />
modern fixing methods for quicker and easier<br />
installation. The new Eden tile will transform<br />
pantile fitting giving contractors an easy-to-fix,<br />
low pitch option when a traditional pantile is<br />
required for aesthetic or planning purposes.<br />
Unlike anything else on the market, the Eden<br />
pantile combines the aesthetics and heritage of a<br />
traditional pantile with time-saving features<br />
previously only seen on Marley’s Lincoln<br />
interlocking tile, including a specially designed<br />
SoloFix channel to make BS 5534’s two point<br />
fixing easier, a flat back on the rear of the tile so<br />
it doesn’t rock during installation and an enlarged<br />
nib for easier nailing. It also has a low minimum<br />
pitch of just 22.5 degrees.<br />
Below: Marley’s Eden tile will transform pantile fitting, giving<br />
contractors an easy-to-fix, low pitch option when a<br />
traditional pantile is required for aesthetic or planning<br />
purposes.<br />
“The Eden has a<br />
traditional profile but<br />
incorporates several<br />
innovative features to<br />
make it quicker and<br />
easier to install to<br />
BS 5534”<br />
Stuart Nicholson, Roof Systems Director at<br />
Marley, says: “In certain areas of the country –<br />
for example Lincolnshire, East Anglia, Norfolk,<br />
Yorkshire, Humberside, the South West and parts<br />
of Eastern Scotland – contractors will need to use<br />
clay pantiles to fit in with surrounding properties.<br />
Yet, the last significant development in traditional<br />
pantiles was the introduction of machine-made<br />
tiles back in the 1700s; much recent<br />
manufacturer innovation has focussed on<br />
creating interlocking tiles due to the market need<br />
for easy-to-fix products. Indeed, with the ongoing<br />
time and skills pressures, modern clay<br />
interlocking pantiles, like our Lincoln, have<br />
become increasingly popular as a quicker, easier<br />
and more cost-effective way of achieving a rustic<br />
pantile aesthetic.<br />
“However, on some projects, due to aesthetic<br />
preference or planning, contractors still need to<br />
use a traditional pantile, but up until now there<br />
hasn’t been an easy way of fixing these to the<br />
latest British Standards.<br />
“That’s why we are launching a new type of<br />
pantile – the Eden – which has a traditional profile<br />
but incorporates several innovative features to<br />
make it quicker and easier to install to BS 5534.<br />
“It also comes in a weathered finish, so it is even<br />
suitable for use on heritage and conservation<br />
projects. Crucially it gives contractors a time<br />
saving, lower pitch, traditional option, creating<br />
the next significant innovation in the pantile’s<br />
timeline.”<br />

Eden test roof: Matt Timby<br />
Traditional roofing specialist Matt Timby, from<br />
Timby Traditional Roofing in<br />
Gainsborough, installed a<br />
test roof for the Eden<br />
tile as part of the<br />
development<br />
stages and says:<br />
“Working in a<br />
traditional<br />
pantile area<br />
means we have<br />
years of experience<br />
of pantile installation.<br />
Eden is great because it<br />
brings a traditional pantile up<br />
to modern fixing specifications and<br />
standards.<br />
“Not only does its uniform design make it easy to<br />
lay but it also uses a clever clipping system<br />
which<br />
is quick<br />
and easy<br />
to install.<br />
Some clipping<br />
systems can be<br />
quite intrusive on<br />
pantiles, affecting the<br />
way they lay but this tile<br />
has been designed with a<br />
special channel, so the clips<br />
fit comfortably behind the tile<br />
below. There is also enough play<br />
in the clips to adjust the tiles slightly<br />
after installation, if required.<br />
“The tiles were a joy to<br />
install and could easily<br />
be used for new or<br />
refurbishment<br />
projects. They look<br />
really good on the<br />
roof because of the<br />
very slight differences<br />
in profile which was an<br />
intentional part of the<br />
design. Traditional pans vary<br />
in shape and mimicking this gives<br />
an authentic appearance when comparing<br />
them to a standard machine-made tile, which<br />
can be so “perfect” they’re almost characterless.<br />
The really clever thing about this tile is while<br />
achieving an authentic look, it retains its<br />
Matt Timby: “Eden is great because it brings a traditional<br />
pantile up to modern fixing specifications and standards.”<br />
consistency in sizing, each laying to the correct<br />
gauge and cover width making it incredibly easy<br />
to lay. The Eden also has a soft leading edge which<br />
helps with the overall look of the finished roof.<br />
“With a pitch of 22.5 degrees, as opposed to 30<br />
degrees for some other machine-made pantiles, it<br />
does give roofers a traditional rather than an<br />
interlocking option for a lower pitch roof. To me<br />
personally, aesthetics are much more important<br />
than time saving and Eden certainly fits the bill<br />
as far as looks go. For roofers who are looking for<br />
a faster, easier way to install traditional pantiles,<br />
these new tiles could certainly save time because<br />
the clipping system is a much quicker way of<br />
installing to BS 5534.”<br />
The new Eden tile is available in three colours,<br />
the traditional Natural Red, a weathered Rustic<br />
Red and Matt Black for the East Anglia market,<br />
with a full range of components and accessories<br />
to complement the tile, including dry fix systems<br />
or mortar-bedded security fixing kits. Eden can<br />
also be purchased as part of a full Marley roof<br />
system, including underlay, battens, fixings and<br />
accessories, backed up by technical support and<br />

Perfectly Pitched<br />
THE CASE FOR CLAY TILES: A<br />
MODERN OPTION FOR PROJECTS<br />
Pitched Roofing Consultant John Mercer, writing on behalf of Edilians, explains why he feels<br />
modern production techniques mean clay tiles are a great solution for many projects, but<br />
stresses how important it is they are installed correctly...<br />
Clay has been a material of choice for our<br />
roofscapes for nearly 1,000 years; the<br />
Romans are credited with introducing clay<br />
roof tiles to Britain during their occupation from<br />
43 AD until their departure in 410 AD, after which<br />
the art of clay tile making was lost for a while.<br />
Concrete roof tiles were first introduced into<br />
Britain in the 1920s, though it was the huge<br />
boom in housebuilding after the second World<br />
War when they really found favour due to mass<br />
production techniques and ease of installation.<br />
Concrete quickly became the mass housebuilder<br />
choice for roofing, accounting for around 60% of<br />
all roofs, with 20% being slate and 10% being<br />
clay. However, modern production methods and a<br />
wide range of tile shapes and colours mean that<br />
clay tile producers, such as Edilians, are now<br />
challenging the dominance of the concrete<br />
producers.<br />
Thriving market<br />
Good quality clay roof tiles can last well over 100<br />
years, though it is more likely that other<br />
components of the roof will require maintenance<br />
or replacement well before the roof tiles, such as<br />
battens, fixings and underlay. As we all know,<br />
there is a thriving market in the UK for second<br />
clay tiles.<br />
When specifying roofing products, it is important<br />
to choose materials that comply with current<br />
British and European Standards to ensure a good<br />
quality, durable roof for the client. Clay tiles<br />
should comply with EN 1304 and must pass 150<br />
cycles of the European test for frost resistance;<br />
EN 539-2, to be deemed suitable for use in the<br />
UK. Edilians’ clay roof tiles are produced from<br />
high quality French clays that achieve pass<br />
results far in excess of the European Standard<br />
test requirements.<br />
Installation<br />
With regards to installation, all tiles and slates<br />
must be secured to resist predicted wind loads.<br />
The security of a roof tile or slate very much<br />
depends upon its fixings; e.g. nails, clips, straps<br />
etc. Slates are ‘double lapped’ therefore each<br />
slate is afforded some protection to wind up lift<br />
by its neighbouring slates. By the same<br />
reasoning, double lapped clay plain tiles also<br />
provide an extremely secure roof covering through<br />
their small size and coverage. So much so, that<br />
in many locations in the UK, plain tiles only need<br />
mechanical fixing (i.e. nailing) in every fifth<br />
course in the local and general roof areas, with<br />
the perimeters having each tile mechanically<br />
fixed. Of course, wind load calculations must<br />
always be carried out to confirm this for each<br />
location – contact Edilians Technical Support for<br />
a fixing specification for every project. The<br />
methodology for calculating roof tile fixings is well<br />
documented in BS 5534: the British Standard<br />
Code of practice for slating and tiling and pitched<br />
roofs should be fixed to withstand wind speeds<br />
only likely to be exceeded once in 50 years.<br />
If natural slate is beyond a project’s budget, then<br />
for an authentic slate appearance, Edilians has<br />
developed its Beauvoise Graphite Slate, which is<br />
the perfect substitute and it comes with other<br />
advantages, such as the speed of installation, no<br />
need for sorting and holing, as well as the<br />
reduction in cost that only a single lapped roof tile<br />
can bring. Being produced from clay, Beauvoise<br />
Graphite combines the riven appearance of slate<br />
with a natural clay material that will keep its rich<br />
slate grey colour for the life of the tile and will<br />
never fade.<br />
Clay is much more than a great slate substitute;<br />
over its 1,000 years’ presence in Britain, clay has<br />
introduced many of the great roof tile shapes that<br />
are now such a part of our roofscapes; for<br />
example, pantile and roman, as well as<br />
Mediterranean-influenced bold roll. Indeed, many<br />
popular concrete tile shapes are very much<br />
influenced by clay tiles.<br />
Modern clay tiles are pressed, which means that<br />
it is possible to incorporate endless technical<br />
features into the upper and lower surfaces of the<br />
tiles to improve security and weathertightness.<br />
Clay is also twice as strong as concrete, which<br />
means that clay tiles can be thinner and therefore<br />
lighter in weight than concrete tiles. All this,<br />
combined with the fact that clay tiles keep their<br />
colour for life, means that they remain a great<br />
option, whilst modern production techniques<br />
mean that clay is not far behind concrete in<br />
terms of cost and ease of installation.<br />

“THE LEARNING CURVE WAS A STEEP<br />
ONE, PARTICULARLY AT THE START”<br />
Neil Harrison is Pre-Construction Director at leading UK commercial roofing company<br />
BriggsAmasco and has been working in the roofing sector for over 30 years. We caught up with<br />
Neil to hear about his thoughts on progressing in the sector, changing perceptions (including his<br />
parents’!) of roofing, and his pet hate – losing projects to cheaper, poorer solutions when you’ve spent<br />
time working to provide technically sound solutions...<br />

to your current position?<br />
NH: I started work in the summer of 1988 for a<br />
local commercial roofing contractor as a trainee<br />
estimator. I was 17 and had been at college the<br />
previous year studying for my A-levels. It hadn’t<br />
gone well, and it was suggested by the college<br />
that I didn’t return for the new term.<br />
My parents were less than impressed and that<br />
disappointment grew when I started a career as a<br />
‘roofer’. However, over time they started to warm<br />
to the idea. My Mother was impressed when I<br />
was given a Barbour wax jacket as a company<br />

as Business<br />
Development Manager.<br />
Coming from a company<br />
of 12 to a business with<br />
hundreds of employees and<br />
a big company feel, it was all<br />
a bit of a shock. The learning curve<br />
was a steep one, particularly at the start.<br />
But I stuck at it, and with the support of a few<br />
great colleagues, some great experiences working<br />
on a huge variety of projects and a few different<br />
roles along the way, it worked out.<br />

working and progressing in the roofing<br />
sector, what would it be?<br />

not look the most exciting choice. However, there<br />

“Winning the argument<br />

poorer solution<br />
because the bottom<br />
line is out by a few<br />
percent”<br />
NH: I wish it was only one… With any role in<br />
pre-construction, the challenge is always how to<br />
work on and manage many projects and bids<br />
simultaneously.<br />
Above: Neil described the Battersea Power Station project as “a true once-in-a-career opportunity and a privilege” to work on.<br />
TC: You must have worked on some<br />
difficult projects over the years. Is there<br />
one that particularly stands out?<br />
NH: Battersea Power Station: a true once-in-acareer<br />
opportunity and a privilege to be involved<br />
with such an iconic building. I pass near the site<br />
most mornings on the train, and seven years after<br />
my first project meeting I still glance across at<br />
the site.<br />
“People are more<br />
important than tools –<br />
they are our most<br />
precious resource”<br />

the project to a much poorer solution because the<br />
bottom line is out by a few percent.<br />
are our most precious resource.<br />
TC: What’s the biggest issue currently<br />
affecting you as a contractor?<br />
NH: Ah, we almost got to the end without a<br />
mention of Brexit… But the uncertainty being<br />
created over the EU situation is definitely holding<br />
the market back.<br />
TC: What about difficult customers? Any<br />
situations that stand out that you can tell<br />
us about?<br />
NH: For 99% of the time the customers are great.<br />
Occasionally you get a difficult one and have to<br />
admit that it’s just not meant to be. But in other<br />
situations, with time and effort, that difficult<br />
customer becomes the best customer, and that’s<br />
a great feeling.<br />
TC: What’s the most frustrating thing<br />
about your job?<br />
TC: And the most satisfying?<br />
NH: When the business is given the opportunity to<br />
get involved in a project at an early stage, with<br />
the time to identify and find solutions to<br />
problems, and then seeing those ideas taken<br />
forward and worked into a successful project.<br />
TC: What’s your most important tool as a<br />
roofing contractor, either in the office or<br />
on site?<br />
NH: People are more important than tools – they<br />
TC: How has the start of <strong>2019</strong> been, and<br />
are there reasons to be positive for the<br />

THE TOP FIVE BENEFITS OF<br />
EPDM ROOFING MEMBRANES<br />
Carl Bailey, from Firestone Building Products, discusses the benefits of choosing EPDM<br />
for both domestic and commercial installations.<br />
EPDM single ply roofing membranes have been used for both new build and refurbishment of flat<br />

1Size Matters While bitumen-based felt<br />
roofing systems are usually supplied as<br />
1m wide sheets and thermoplastic singleply<br />
membranes can be supplied at widths of up<br />
to 2m, Firestone’s RubberGard EPDM membrane<br />
can be ordered in any width between 3m and<br />
15m on a 30m roll. This is because the<br />
manufacturing process for EPDM enables larger<br />
scale sheets to be assembled during production,<br />
rather than being limited by the size of the<br />
extrusion line.<br />
The roofing contractor can select a width that<br />
offers the best solution for the size and layout of<br />
each individual roofing project, which saves time<br />
and supports improved roof integrity by reducing<br />
the number of seams; the most time-consuming<br />
and critical element of any installation.<br />
2The Right Fix Along with varied<br />
choice of membrane size,<br />
EPDM roofing systems<br />
also offer a varied array of<br />
fixing systems, providing<br />
greater design flexibility for<br />
use with almost any<br />
substrate or roof build-up.<br />
Firestone’s RubberGard EPDM<br />
roofing system can be installed as<br />
a fully-adhered or mechanically-fixed<br />
system and can be used for inverted, ballasted,<br />
green and modular roofs.<br />
Adhesives are usually used with smaller widths<br />
of EPDM and Firestone has developed a waterbased<br />
adhesive specifically for use in factorybased<br />
modular construction. This is also ideal for<br />
Left: Carl Bailey, Firestone Building Products.<br />
occupied buildings or any<br />
environment where<br />
nuisance odours may be<br />
an issue.<br />
For mechanically-fixed<br />
roofs, which are always<br />
advised when using a larger<br />
width of EPDM, Firestone has<br />
developed a fixing system that does not<br />
penetrate the membrane, avoiding any<br />
vulnerability to leaks around the fixing system.<br />
3Fantastically Elastic EPDM is a naturally<br />
and permanently elastic material, with over<br />
300% elongation. As a result, EPDM roofs<br />
are very resilient throughout their service life.<br />
An EPDM roof can flex to cope with any<br />
differential movement between building<br />
components, avoiding the need for any complex<br />
expansion joints unless required by building<br />
regulations. EPDM does not crack or split at very<br />
low temperatures, nor does it soften or melt at<br />
very high temperatures and it can cope with<br />
temperature shock from rapid temperature<br />
fluctuation.<br />
With an increasingly erratic climate, the U/V<br />
resistance and long-term elasticity offered by<br />
EPDM present compelling reasons to specify<br />
systems like RubberGard EPDM.<br />

4Environmentally Responsible Featured in<br />
the Green Guide and contributing to a<br />
BREEAM summary A+ rating over an<br />
appropriate support, EPDM is an inert material,<br />
containing no plasticisers, heavy metals or<br />
chlorine, which means there is no change in the<br />
material even when exposed for many years.<br />
EPDM’s extended service life significantly lowers<br />
its environmental impact, and the membrane is<br />
completely recyclable.<br />
5Heat & Flame Free Installation is totally<br />
heat- and flame-free, with all joints formed<br />
using a self-adhesive splice tape. This<br />
avoids any fire risk from the roofing project, along<br />
with any fire-risk related insurance costs or fire<br />
safety wait times for installation teams at the end<br />
of a day on site.<br />
As no electrically-powered tools are needed,<br />
there is no requirement for any temporary or<br />
permanent power source; a significant<br />
advantage for both remote locations where<br />
getting a generator to site may be onerous and<br />
for residential areas where a generator could<br />
create nuisance noise.<br />

Metal Standing Seam<br />
STANDING THE TEST OF TIME<br />
Gareth Holvey, Technical Manager SSR2 at Catnic, explains why he feels standing seam<br />
metal roofing provides such a viable alternative to traditional roofing options.<br />
Ease of Installation<br />
For roofing contractors, ease of installation<br />
is important to ensure projects can be<br />
delivered efficiently and to schedule, and<br />
that there is reduced time spent at height.<br />
A standing seam steel roof is lightweight – in fact<br />
seven times lighter than clay or slate tile<br />
equivalents. This means that handling, carrying<br />
and manoeuvring the material on site is much<br />
easier, which is an important consideration when<br />
working at height in order to improve overall safety.<br />
Roofing contractors should also look for pre-finished<br />
steel standing seam roofing systems that utilise a<br />
simple locking design with pre-punched fixing holes<br />
to aid installation. This will make the fixing<br />
process much quicker and reduce the amount of<br />
time required to deliver a project. Systems that<br />
are not reliant on roll forming or seaming on site<br />
can help ensure workmanship levels and product<br />
performance both achieve a high standard.<br />
Environmental benefits<br />
With the government striving to achieve reductions<br />
of carbon emissions, we have understandably<br />
seen a drive from the construction industry to<br />
improve the energy efficiency of UK homes and<br />
buildings. Therefore, wherever possible, only<br />
building materials that can demonstrate clear<br />
environmental credentials, should be specified,<br />
including the choice of roofing.<br />
As such, systems with the highest BREEAM levels<br />
possible are ideal – a Green Guide-recognised<br />
system will deliver peace of mind when it comes to<br />
environmental credentials. In addition, leading precoated<br />
metal standing seam systems can easily<br />
incorporate solar panels, further increasing the<br />
energy efficiency of the project. A fixing bracket can<br />
be screwed into the standing seam upstand to allow<br />
photovoltaic panels to be installed without needing<br />
to place holes through the roof. This can reduce<br />
time spent installing the technology<br />
whilst retaining roof integrity.<br />
Guaranteed<br />
performance<br />
Of course, whilst ease of<br />
installation and<br />
environmental credentials<br />
are a factor, these materials<br />
also need to stand the test of time.<br />
Consideration must be given to whether the<br />
material can withstand British weather, as this<br />
will affect the longevity of the product.<br />
Proving confidence in its products, Catnic has<br />
recently launched its free of charge Confidex<br />
Home guarantee. Offered direct to the<br />
homeowner, this 25-year warranty provides<br />
complete confidence in the quality of the<br />
advanced paint coating applied to the steel, and<br />
is in place whether the SSR2 system is used<br />
either as roofing or cladding, and regardless of<br />
where the property is located – including coastal<br />
regions. In addition, the guarantee is easily and<br />
fully transferable in the event the property is sold<br />
to new owners – an excellent benefit roofing<br />
contractors can provide to their customers.<br />
To ensure a robust specification – it is important<br />
to ensure that the standing seam roofing choice<br />
will meet all the relevant legislation. The SSR2<br />
Roofing and Cladding System is manufactured<br />
from Tata Steel’s Colorcoat HPS200 Ultra prefinished<br />
steel, and is CE Marked in accordance<br />
with BS EN 14783:2013. It also meets Class 0<br />
‘low risk’ fire classification requirements of the<br />
UK Building Regulations.<br />
When used as part of a roof cladding system, the<br />
system has a Class AA /B roof (t4) performance<br />
rating according to BS 476 Part 3 / EN1187 and<br />
meets all UK roofing application requirements.<br />
Training and education<br />
Of course, no matter how long<br />
roofing contractors have<br />
been in the business –<br />
taking advantage of<br />
training and education will<br />
always remain important.<br />
Catnic now offers a new<br />
CPD – a 45-minute session<br />
that explores the performance<br />
and aesthetic considerations of prerefinished<br />
steel, including installation solutions, as<br />
well as building methods and regulations.<br />
Ensuring weekly CPD obligations are easily<br />
satisfied, it is taught face to face and can provide<br />
roofing contractors confidence in the product and<br />
installing it.<br />
A beautiful and versatile aesthetic<br />
Loved by architects and customers alike for its<br />
range of colours (including Anthracite, Terracotta<br />
and Green Grey) that complement both traditional<br />
and modern finishes, the tonal matt shades<br />
integrate seamlessly between different facades<br />
including glass, brick, wood, stone and render<br />
delivering effortless modern finishes.<br />
There are a range of factors to consider when<br />
specifying a roofing system for a residential build,<br />
whether it is for a new build or refurbishment. By<br />
working with and recommending a pre-finished<br />
steel roofing system, contractors can provide end<br />
clients with a quick-to-install solution – that can<br />
contribute to a sustainable build with a lasting<br />
and beautiful aesthetic.<br />

Common Mistakes<br />
PITCHED ROOFING INSTALLATION:<br />
COMMONLY MADE MISTAKES<br />
We asked Pitched Roofing Consultant John Mercer to discuss some of the common<br />
mistakes contractors can make when installing pitched roofing products and<br />
materials...<br />
Firstly, I want to start on a positive note;<br />
there have been many advances in pitched<br />
roofing during my career, in both materials<br />
and installation techniques. These have been<br />
driven by several factors, including revisions to<br />
British and European design and installation<br />
Standards, with these, in turn, being motivated<br />
by organisations such as the National Federation<br />
of Roofing Contractors (NFRC) and National<br />
House Building Council (NHBC) as well as<br />
building material producers.<br />
However, new products and new practices can<br />
sometimes introduce new challenges. There was,<br />
for many years, a lack of awareness amongst<br />
contractors of the requirements of BS 5534,<br />
particularly relating to roof tile fixings. However,<br />
persistent campaigns within the industry, coupled<br />
with roof tile manufacturers’ development of<br />
software to make calculating fixing specifications<br />
extremely quick and simple, has dramatically<br />
raised awareness in the last five years.<br />
Remember, a fixing specification should be<br />
calculated for every roofing project.<br />
Underlays<br />
The introduction of ‘breathable’ underlays<br />
brought with it several complications. Firstly,<br />
even the word ‘breathable’ is misleading. Early<br />
marketing campaigns and third-party certification<br />
of some of these products led people to believe<br />
that roof space ventilation was no longer<br />
required, with confusion surrounding details such<br />
as air and vapour control layers in ceilings. Even<br />
the way lightweight underlays are installed can<br />
cause problems. These were originally designed<br />
to be installed over rigid sarking or insulation, but<br />
here in the UK we traditionally lay underlay<br />
“The important thing is for all industry sectors to<br />
work together to develop, improve and overcome<br />
the issues we encounter”<br />
unsupported over rafters – not in Scotland, I hear<br />
you say. It is more difficult to lay lightweight<br />
underlay with a drape and the underlay does not<br />
naturally seal around the batten nail holes.<br />
Therefore, the combination of no drape and no<br />
seal at the nail holes can result in water<br />
penetration, whether it be from rainwater driven<br />
through the roof tiling or condensation within the<br />
batten cavity. To overcome these issues,<br />
consider using a proprietary nail tape to seal the<br />
nail holes and counter-battens in place of<br />
underlay drape. It is important that the installer<br />
obtains the correct installation advice from the<br />
product manufacturer and is familiar with the<br />
recommendations given in BS 5250 on roof<br />
space ventilation.<br />
Low pitch roofs<br />
This leads me to another common installation<br />
problem; that of low pitch roofs. For many years,<br />
there has been commercial pressure on roof tile<br />
manufacturers to reduce the minimum<br />
recommended roof pitches for some of their<br />
products. Manufacturers have responded through<br />
vigorous wind-driven rain testing and<br />
improvements to their tiles. This, in turn, has<br />
encouraged designers and contractors to<br />
construct buildings with lower roof pitches.<br />
Low pitch roof-related problems often manifest<br />
themselves on small, domestic, single-storey<br />
extensions. Tiles, which perform adequately when<br />
laid perfectly in a wind tunnel, may not perform<br />
so well when they are laid around, for example,<br />
roof windows, where the flashings cause the tiles<br />
to lift and not seat as well as they should. A<br />
common mistake is to shed water onto a lowlevel<br />
extension roof from a higher roof through a<br />
downpipe or valley. This volume of localised<br />
water can overwhelm the roof tiles, causing<br />
leakage. Similarly, where a roof has a low pitch<br />
combined with an overly-long rafter length, the<br />
tiles in the courses close to the eaves can be<br />
flooded due to the volume of water from higher up<br />
the roof slope.<br />
It is important to avoid shedding water onto lower<br />
roofs and to follow the roof tile manufacturer’s<br />
advice on minimum roof pitch/maximum rafter<br />
length. Seal all penetrations, laps, and junctions<br />
in the underlay layer.<br />
In summary, yes, of course, roofers make<br />
mistakes, but I hope I have demonstrated here<br />
that the important thing is for all industry sectors<br />
to work together to develop, improve and<br />
overcome the issues we encounter through good<br />
design, improved products and correct<br />
installation.<br />

Common Mistakes<br />
HANDRAIL, GUARDRAIL & SAFETY<br />
BARRIER INSTALLATIONS<br />
Christian King, General Manager at Kee Systems, points out some of the common mistakes<br />
made when installing safety systems.<br />
Not following the design calculation that<br />
provides the compliant upright tube<br />
specification, correct spacing between<br />
uprights, the required anchor embedment to<br />
achieve the required design load: Correct<br />
planning is vital, otherwise the barrier won’t<br />
achieve what it’s being designed to do, which is<br />
to protect people. For example, barriers, handrails<br />
and guardrails must meet minimum height<br />
requirements and be able to withstand various<br />
forms of load, as required under Building<br />
Regulations and BS6180. Pedestrian handrails<br />
need to be designed to achieve 740 Nm design<br />
load. If the system isn’t designed correctly, then<br />
you will find that the system does not withstand<br />
the correct loading. Correct design calculations<br />
can also help to save money, as you’ll be able to<br />
calculate the spacings accurately. We often find<br />
that systems are installed to what a company<br />
thinks is the safest specification, but in fact, they<br />
have often overcompensated on the spacing<br />
between uprights and as a result, the railing<br />
system has cost more.<br />
Don’t assume you know how to install the<br />
systems correctly and to a compliant<br />
standard: Safety barrier systems can be<br />
installed quickly and easily using fittings such as<br />
Kee Klamp, but you still need<br />
to know what you’re<br />
doing. Common<br />
mistakes can often<br />
be seen on stairs or<br />
ramps where the<br />
handrail may be<br />
below the required<br />
900 – 1100mm<br />
height or the handrail<br />
has just been installed on<br />
one side of the stair or ramp<br />
instead of both sides as required. You<br />
can also find that where there is a drop off, a<br />
curb or curb rail has been omitted to prevent<br />
wheelchairs from slipping out from under the<br />
railing. In some cases, a mid-rail will provide<br />
sufficient protection.<br />
“If you are going to<br />
install a handrail,<br />
guardrail or safety<br />
barrier using<br />
components, always<br />
speak to a company<br />
that understands the<br />
complexities of<br />
installing these<br />
systems first”<br />
Wrong fixing detail used: We have seen cases<br />
where a base flange has been fixed to brickwork<br />
with non-suitable anchors or not cored, or where<br />
wall fixings have been used as base flanges. It<br />
won’t be long before these safety railings or<br />
handrails start to become unstable and either<br />
wobble or work loose from the brickwork or<br />
substrate it’s fixed to,<br />
making the system noncompliant<br />
and<br />
potentially a hazard.<br />
When fixing a<br />
pedestrian handrail<br />
to brickwork, we’d<br />
recommend using a<br />
78mm diameter<br />
diamond core drill,<br />
250mm deep for each<br />
upright and then resin fix the<br />
uprights into position to achieve the<br />
required strength and durability.<br />
Trying to save money by installing a<br />
galvanised DDA compliant system and then<br />
painting it instead of having it powder-coated:<br />
Painted systems will scratch or flake within<br />
weeks, if not days. Polyester powder coating the<br />
tube and components will provide a finish that’s<br />
chip, scratch and fade resistant and will also<br />
comply with the requirements of the Equality Act<br />
by providing a finish that’s not cold to the touch.<br />
General comment: The benefit of using tube and<br />
fittings is that if a system is incorrect, it may<br />
simply be a case of adjusting it or replacing a<br />
section, which you can’t do with fabricated<br />
systems. However, in all cases, we’d say that if<br />
you are going to install a handrail, guardrail or<br />
safety barrier using components, always speak to<br />
a company that understands the complexities of<br />
installing these systems first to make sure that<br />
what you are proposing is correct.<br />

Cold Applied Liquids<br />
ADDITIONAL SPACE CHALLENGES<br />
By Justin Pitman, Sales Director for Proteus Waterproofing<br />
The growing movement towards building<br />
more apartments and community housing<br />
has seen a major change in the way that<br />
many of us now live, but with that trend comes<br />
new challenges for the waterproofing industry.<br />
Increasingly, balconies, flat roofs and service<br />
areas including walkways and stairwells have<br />
grown in importance. Such structural features<br />
provide endless opportunity for residents without<br />
gardens to create places for drying washing,<br />
growing plants and flowers, or simply to enjoy<br />
well-earned fresh air.<br />
Sooner or later, however, those roofs, balconies<br />
and other communal areas need refurbishing or<br />
waterproofing, and by their very nature in such<br />
confined spaces it can cause massive problems<br />
for residents who have to contend with significant<br />
disruption, pollution or in some cases, the<br />
prospect of having to leave their homes.<br />
It could be why cold applied liquid solutions are<br />
rapidly becoming the waterproof membranes of<br />
choice – particularly for local authorities and<br />
housing associations that are frequently faced<br />
with the dilemma of delivering essential<br />
refurbishment without upsetting tenants and<br />
other residents. Cold applied also ticks all the<br />
boxes for local authority landlords understandably<br />
anxious to keep fire risk to the minimum.<br />
Refurbishing an apartment block is not just simply<br />
a case of overlaying a new waterproof membrane<br />
in a few hours. The old decking or waterproof<br />
layer frequently has to be removed and when the<br />
new membrane is applied the devil is in the<br />
detailing – which is both time consuming, very<br />
disruptive and depending on the product you use,<br />
creates a lot of offensive odours.<br />
Fortunately there are now waterproofing solutions<br />
for roofs, balconies and walkways that both<br />
residents and building owners will welcome. They<br />
are virtually odour free, can be<br />
installed and ready to walk on<br />
in under two hours so<br />
minimum disruption and<br />
best of all – they are<br />
less expensive – a total<br />
win, win.<br />
The secret is in the<br />
seamless application for<br />
so long enjoyed by Mastic<br />
Asphalt and hot melt products.<br />
While both are excellent for most types of<br />
flat roof and walkway applications, many<br />
landlords are now unwilling to accept molten<br />
products, even though the risk of fire is negligible.<br />
Higher costs, particularly with mastic asphalt, are<br />
also a factor.<br />
A seamless solution<br />
Cold-applied systems have taken the lead by<br />
offering other advantages over traditional types of<br />
waterproofing. As well as offering a ‘safer’<br />
application, the liquid coating can be used to<br />
deliver a seamless finish as it forms a<br />
permanently elastic, seamless membrane. Ideal<br />
for the long-term waterproofing of complex roof<br />
details around pipes, upstands and gutters, the<br />
system is a popular specification for<br />
contemporary roofing projects where penetrations<br />
are becoming ever more prevalent.<br />
In recent years we have seen more and more<br />
projects requiring intricate detailing works around<br />
rooftop penetrations. Cold-applied systems<br />
minimise the element of risk associated with<br />
torch-on applications with no naked flames or<br />
boilers involved at any time with the installation<br />
process. Many liquid applied systems also exhibit<br />
extremely low odour, making for a quick, simple<br />
and safe-to-apply waterproofing solution,<br />
particularly when you have an application in<br />
confined spaces such as balconies, walkways or<br />
other hard-to-reach areas.<br />
Other factors such as the time<br />
to complete a contract also<br />
have to be taken into<br />
consideration,<br />
particularly with budgets<br />
under increasing<br />
pressure. This particularly<br />
applies to new build.<br />
In the past some of that down<br />
time, particularly the need to wait 28<br />
days for green concrete to cure, has been<br />
unavoidable – or at least that was the case –<br />
until now. All that has changed following the<br />
launch of new types of waterproof membrane –<br />
which some believe will revolutionise the<br />
construction industry.<br />
Getting other trades on site as quickly as possible<br />
is frequently delayed until the building has been<br />
waterproofed and conventional wisdom has<br />
always dictated the 28 day rule for green concrete,<br />
but the new cold applied systems can be laid<br />
within three days of the concrete being installed<br />
allowing the building to be waterproofed some 24<br />
hours later. This will help to significantly reduce<br />
costs in the public sector as the Government<br />
releases more funds for social housing.<br />
So whether it’s new build or refurbishment, I<br />
believe cold applied liquid solutions are leading<br />
the way, and as we build more and more flats and<br />
apartments and renew existing buildings, then we<br />
are going to need waterproofing solutions that can<br />
rapidly deliver with the minimum of disruption –<br />
the future is liquid.<br />

Pitched & Flat Roofing<br />
THE SHAPE OF THINGS TO COME:<br />
SIGNIFICANT YEARS IN BMI’S HISTORY<br />
With BMI UK & Ireland’s iconic BMI Redland brand celebrating 100 years of concrete tile<br />
manufacture in the UK, ahead of its formal celebrations later in the year, the company<br />
continues to look back over its 180-year heritage.<br />
While 1919 – when Redland was formed<br />
as the then Redhill Tile Company in<br />
Reigate, Surrey – was an important<br />
moment for pitched roofs in the UK, representing<br />
the start of domestic concrete tile manufacture,<br />
1923 proved to be almost as important for flat<br />
roofing when Icopal, then known as D Anderson &<br />
Sons, relocated from Belfast to Stretford,<br />
Manchester.<br />
At the time, Anderson was the first factory to<br />
make the area its home in what was then fields<br />
as far as the eye could see. Today, the factory,<br />
which is still the company’s main manufacturing<br />
plant for its BMI Icopal ranges, is in the heart of<br />
Manchester’s Trafford industrial district – with<br />
other global names such as Kellogg’s, Adidas and<br />
L’Oréal for neighbours.<br />
Some of the site’s original buildings remain and<br />
true to its reputation of creating roofs that last,<br />
one of the buildings features a rare engineered<br />
timber roof structure known as a Belfast Truss –<br />
designed, according to Construction History Vol.<br />
17, by Anderson-founder David himself.<br />
The industrial revolution brought about the need<br />
for clear span industrial buildings, which in turn<br />
inspired the development of a variety of timber<br />
truss types. And although so-called bowstring,<br />
barrel-form and other ‘chord and lattice’ truss<br />
roofs had been built since medieval times, the<br />
first “true” Belfast Truss – a clever laminated<br />
construction, designed to maximise the use of<br />
scrap timber – was fabricated by Anderson &<br />
Sons in Belfast in 1896.<br />
A few years later, after Anderson’s Manchester<br />
move, the general strike struck in 1926 and had<br />
a profound and positive impact on the popularity<br />
“One of the buildings<br />
features a rare<br />
engineered timber roof<br />
structure known as a<br />
Belfast Truss”<br />
of concrete tiles – owing to a resulting shortage<br />
of clay tiles; yet not so profound an impact as the<br />
Second World War.<br />
While the WW2 blitz wrecked a large number of<br />
British cities, it was London that bore the brunt<br />
with one million of the total estimated loss of the<br />
two million homes destroyed. The urgent need to<br />
replace these in the post-war period saw a huge<br />
surge in house-building and the Redland 49<br />
medium-format interlocking cambered tile<br />
became the roof covering of choice. Launched in<br />
1949, it was the first single-lap concrete tile and<br />
its use is still widespread throughout the city.<br />
Redland 50 Double Roman<br />
In slightly les -pressured circumstances, 1950<br />
saw the launch of the Redland 50 Double Roman.<br />
The first variable headlap tile, as the name<br />
suggests Double Romans hark back to the Roman<br />
invasion of Britain in 43 AD. The tiles are based<br />
on their imbrex and tegula tiles and modern<br />
Double Romans come as interlocking concrete<br />
Old Anderson and Redland adverts.<br />
tiles, mimicking the effect of the original ancient<br />
profile while being compatible with a wide range<br />
of fittings and accessories.<br />
In 1954, Redland invested £6,000 in a small<br />
German company, Braas GmbH: a name to become<br />
significant in the ultimate destiny of BMI’s much<br />
loved Redland brand. It was by now called Redland<br />
Tiles and, having purchased the Moorhouse Brick<br />
and Concrete Tile Product Company near<br />
Westerham, was publicly floated and quoted on<br />
the London Stock Exchange in 1955.<br />
As November’s concrete tile centenary<br />
approaches, BMI UK & Ireland will be highlighting<br />
more pitched and flat roofing key dates,<br />
innovation and achievements in its development,<br />
leading to the present day.<br />

MARLEY HELPS REIMAGINE RURAL<br />
A development in the village of Waddesdon, which has been devised and managed by the Rothschild Foundation,<br />
has used Marley’s Double Acme Camber tile to create a striking aesthetic that is reimagining rural living.<br />
Made up of 75 homes, the residential project has used over half a million of Marley’s Acme Double Camber tiles in Burnt<br />
Flame. With the tiles used not only on the roofs but also applied vertically, they were able to perfectly complement the<br />
project’s Scandinavian inspired design. Marley’s technical team worked closely with the project’s architects, C.F. Møller, to<br />
assist with CAD drawings to ensure a suitable build-up and ventilation of the roof.<br />
Marley’s tiles were used on this project which<br />
won ‘Best Conceptual Design’ at the <strong>2019</strong><br />
Sustainable Architecture awards.<br />
Andrew White, Area Sales Manager at Marley, said: “C.F. Møller was clear from the outset on the type of development it wanted to create. Turning away from<br />
traditional design, instead favouring an approach which reflected modern living, to deliver a contemporary appearance which complemented the historic village<br />
setting. Seeking a crisp, clean look, it was therefore important that the roofs of the homes also reflected this vision. Marley’s Acme Double Camber in Burnt Flame<br />
was the ideal choice. As it is suitable for vertical applications it was able to deliver a finish which meant the transition from roof to exterior wall was seamless. In<br />
addition, the tile was also able to interact with other exterior elements of the build including window reveals, cladding at the gables, and guttering, which was a<br />
significant challenge on the build.” www.marley.co.uk<br />
ZINC-ING OUTSIDE THE BOX!<br />
You can now buy Zinc Box profile gutters on the Rainclear Systems website rainclear.co.uk.<br />
If you are unsure which size gutter best suits your project,<br />
call 0800 644 44 26. www.rainclear.co.uk<br />
The Quartz Zinc rainwater system is also available in a half round profile with simple to install<br />
fittings for the average domestic project. But the two systems are aimed at different projects and<br />
skills-sets. The Box profile system is more suited to a large house with a high-pitched roof or small<br />
commercial buildings and designed to be soldered (at gutter joints and patch outlets). The preweathered<br />
zinc used to manufacture the rainwater systems will not discolour, distort or become<br />
brittle over time. Cut edges will not corrode as the metal develops a natural self-protecting patina.<br />
BREEAM HELP FROM ABOVE<br />
A quantifiable means of achieving BREEAM points is being pioneered by Hambleside Danelaw,<br />
via its Zenon GRP rooflights.<br />
Above: Zenon’s EPD applies to a range of site-assembled<br />
and composite panel rooflight configurations. “The<br />
concept of rooflights being able to quantifiably contribute<br />
towards a BREEAM rated project in this way is a major<br />
innovation for the market.”<br />
Zenon GRP in-plane rooflights have attained an independently assessed Environmental Product Declaration<br />
(EPD). The accreditation enables a contribution of 1.5 points towards a building’s BREEAM rating.<br />
“Rooflights have always been acknowledged as contributing towards BREEAM, but it has always been an<br />
intangible element,” explained Paul Hanratty, Hambleside Danelaw. “The EPD makes that contribution<br />
tangible, quantifiable; it gives reliable evidence.” www.hambleside-danelaw.co.uk<br />
GOAL ACHIEVED WITH SAFESITE ASSIST<br />
Safesite has provided a safety solution for Wolverhampton Wanderers FC’s training grounds.<br />
Rooftop safety solutions at<br />
Wolves’ training ground.<br />
Using KeeGuard, Kee Walk Step-over and a Bespoke Access Platform, Safesite offered security for the team to be able to film the<br />
club’s training sessions from the building’s rooftops. Following a thorough site survey, a Kee Walk Step-over was put in place from<br />
the office balcony and led onto a Kee Walk walkway which provides a safe, demarcated route to the flat roof area. This proved to be<br />
the perfect solution as it is anti-slip and suitable to walk on in various weather conditions. Safesite also recommended that a<br />
Bespoke Access Platform be constructed on the roof to allow training sessions to be filmed from multi-angles in complete safety.<br />
Lastly, KeeGuard has also been installed to provide edge protection to the exposed edge on the roof. www.safesite.co.uk<br />

ROBUST ROOF FROM BMI<br />
Students at George Hastwell School, an academy in Barrow-in-Furness, are now sheltered by a roof that is built<br />
to a specification from BMI UK & Ireland that is guaranteed to withstand the harsh coastal climate for 20 years.<br />
The school commissioned Cunliffes, working with BMI, to draw up the school’s Capital Funding Application to the Schools<br />
Funding Agency to replace the original roofs. Wind uplift calculations were required to find the best application method.<br />
George Hastwell School.<br />
The roof details were sent to BMI to complete the calculations and determine the correct fixing for the location. In this case<br />
it proved particularly important as the calculations showed that both the membrane and the insulation beneath would be subject to windloads of up to 2.79 kN/m²<br />
(kilonewtons per square metre) at the corners. This meant that the insulation had to be bonded separately using TPI insulation adhesive – a foaming, odourless, VOCfree<br />
two-part rapid curing polyurethane adhesive manufactured from bio-renewable materials. The 1050m² project, installed by BMI’s IMA approved contractor<br />
Pendlebury & Sons, consisted of a number of roofs with either concrete or plywood decks. For the non-flammable concrete substrates, BMI Icopal Tecnatorch Sand<br />
and Siplast Primer were applied as the vapour control layer. For the plywood decks, the vapour control layer comprised BMI Icopal TorchSafe TA VCL Sanded and SA<br />
Primer. Thermazone Torch On Insulation was then bonded to both vapour control layers with TPI Insulation Adhesive. Total Torch Vapour Dispersion Layer was installed<br />
as underlay, followed by Firesmart Thermaweld Capsheet in Charcoal to complete the waterproofing system. www.bmigroup.com/uk<br />
THE BIT BETWEEN THEIR TEETH!<br />
SikaBit, the Safe2Torch reinforced bitumen roofing system from Sika, has been used to<br />
upgrade the roof of a social housing block in the London Borough of Southwark.<br />
Hambro Roofing used the SikaBit system at Castlemead<br />
House after seeing the advantages of the SBS/APAO<br />
hybrid technology.<br />
Craig Smith from Sika explained: “The client was keen that any roof refurbishment should be carried out<br />
using a Safe2Torch reinforced bitumen membrane, but it was clear that there was an opportunity to<br />
upgrade the existing system with more advanced bitumen technology. SikaBit’s best-of-both-worlds SBS<br />
and APAO hybrid bitumen technology provided the ideal solution to achieve consistency of specification<br />
while enhancing the roof build-up. https://gbr.sika.com<br />
SL8: ACCELERATE AND RENOVATE!<br />
Forticrete is meeting the increasing demands of the roofing market with its innovative large<br />
format, thin leading edge roof tile, SL8.<br />
SL8: “We’ve created SL8 as we saw a need in the market<br />
for a thinner edge tile, that is up to 50% thinner than large<br />
format varieties, allowing roofing contractors to achieve a<br />
unique minimum pitch of 17.5 degrees.”<br />
Combining the visual aesthetic that replicates real slate with technical features of an interlocking tile, SL8<br />
provides both superior coverage and a better-looking roof. The tile, which is 420mm by 390mm with a<br />
hanging length of 396mm, offers excellent coverage requiring just eight tiles per m². SL8 has been<br />
granted patents to cover the camber of the tile, interlocking design and features and dry verge design,<br />
meaning there is no other tile like it in the marketplace. www.forticrete.co.uk<br />

SIKA TO THE RESCUE!<br />
The Scottish Fire and Rescue Service depot in Newbridge, Edinburgh, has been equipped with a<br />
new training centre.<br />
The 800m² ‘TSB’ building required a waterproof roof system that not only offered long-term protection<br />
against the elements, it needed to be quick to install and flexible enough to accommodate a number of The Scottish Fire and Rescue Service depot in Newbridge.<br />
roofing details. Sika-Trocal’s fully-bonded SGK membrane system proved more than ideal for the task. Main contractor Robertson Construction appointed Reid<br />
Roof to carry-out the flat roof’s installation. Work initially involved applying Sika S-Vap 5000E SA, a multi-layer, self-adhesive air and vapour control layer, to<br />
the low-pitched roof’s concrete substrate. Comprising polymer-modified bitumen, glass-fibre mat reinforcement and an aluminum foil as top layer, S-Vap’s<br />
superb strength enables simple, rapid installation and exemplary, airtight roof construction. A layer of Sika-Trocal INNObond, a durable, easy-to-apply, highperforming<br />
insulation board, provided a quality thermal base for the SGK membrane. As well as supplying high tensile strength, Sika-Trocal SGK provides<br />
outstanding weathering and excellent flexibility in cold temperatures, which along with its easy-fit benefits make it the ideal membrane for exposed flat roofs.<br />
The light-grey membrane was affixed using the Sika-Trocal spray-adhesive range and Sika-Trocal SG, a 1.5mm multi-layer, synthetic roof waterproofing sheet,<br />
provided the aesthetically-pleasing solution for the roof’s various vertical upstands. https://gbr.sika-trocal.sika.com<br />

Flat Roofing Solutions
Pre-coated Aluminium<br />
A COMMERCIAL ADVANTAGE<br />
Simon Gregory, Sales Director at Proteus Facades, explains why he feels offering pre-coated<br />
aluminium rainscreen cladding can offer real benefits for installers.<br />
In recent years, rainscreen cladding systems<br />
have evolved to a stage where they now<br />
provide architects and designers with the<br />
freedom to create truly eye-catching structures.<br />
Most of these advances have centred on how<br />
aluminium is presented, such as pre-coat<br />
aluminium, which is where the material is coilcoated<br />
with a tough, flexible paint system. What<br />
really makes pre-coated aluminium popular with<br />
architects and designers is that it is suited to<br />
larger building facades where it provides a value<br />
engineered solution and striking aesthetics. It is<br />
for this reason that a growing number of<br />
installers are adding it to their portfolio.<br />
Pre-coated aluminium is available in a wide<br />
range of colours (in addition to any RAL or BS<br />
colour), finishes and textures, which elevates it<br />
above ‘flat’ finishes such as PPC. It is this<br />
characteristic that allows the creation of similar<br />
aesthetics to materials such as stainless steel,<br />
anodised aluminium, copper, zinc and brass.<br />
That’s because pre-coating aluminium offers<br />
“Offering pre-coated<br />
aluminium rainscreen<br />
cladding can give<br />
contractors a real<br />
commercial”<br />
advantage”<br />
much more scope, with the ability to recreate a<br />
wide range of metallic finishes to give the façade<br />
a cutting-edge futuristic look. Manufacturers of<br />
pre-coated aluminium have extended the range<br />
and offering to include metallic, coloured,<br />
woodgrained and textured finishes. These are<br />
suitable for use as rainscreen cladding, flashings,<br />
fascias, rooflines and other metal fabrications.<br />
Advances in the quality of pre-coating ensures a<br />
uniform paint layer and consistent colour. And,<br />
because pre-coated aluminium can be bought in<br />
large quantities and with a consistent finish it<br />
minimises shade variation between panels.<br />
However, you have to factor in that pre coated<br />
aluminium does have a fairly high minimum order<br />
quantity for a single order, which is why for<br />
smaller quantities, a PPC finish is the only<br />
method commercially available. PPC finishes<br />
tend to work best if you are looking for solid, flat<br />
colours, meaning it is fairly limited when you<br />
need something slightly different.<br />
An electrifying facade<br />
These benefits mean that offering pre-coated<br />
aluminium rainscreen cladding can give<br />
contractors a real commercial advantage. Take<br />
the new European IT headquarters for global<br />
electrical wholesaler, City Electrical Factors<br />
(CEF), for example (see below). Architects<br />
FaulknerBrowns designed the £10m Data, IT and<br />
Marketing headquarters based just outside of<br />
Durham, using a pre-coat aluminium façade,<br />
along with a variety of other materials including<br />
copper and ceramic, which represent the<br />
components found within an electrical cable,<br />
CEF’s staple product.<br />

Pre-coated Aluminium<br />
Above: Janet Nash House. “The panels were fitted by installer Topside, in between vertical and horizontal aluminium anodised fins to create a sheer façade.”<br />
winning building, known as Janet Nash House,<br />
was to create a contemporary workplace solution<br />
which embodies and reflects CEF’s drive and<br />
commitment for innovation. The structure is split<br />
into two areas, each with unique spatial qualities<br />
to support the requirements of the different<br />
departments across the company.<br />
The southern ‘L’ shaped block features a striking<br />
façade executed in Proteus HR Euromax AluNatur<br />
Elox Anodised Brushed pre-coated aluminium, for<br />
which FaulknerBrowns took inspiration from the<br />
foil shield of a coaxial cable. This is a lightweight,<br />
strong and versatile cladding panel that provides<br />
aesthetic screening to building facades. The<br />
cladding panels feature an aluminium honeycomb<br />
core, structurally bonded between two thin<br />
gauges of lightweight metal skin to create an<br />
optically flat panel.<br />
The honeycomb cladding panels fabricated for<br />
Janet Nash House using Euromax AluNatur outer<br />
skins with an Elox Anodised Brushed pre-coated<br />
finish recreate the coaxial pattern found within an<br />
electrical cable. The designers specified a precoat<br />
finish because it offered a value engineered<br />
method of recreating the granular appearance of<br />
stainless steel but still within the client’s budget<br />
expectations.<br />
Euromax AluNatur material consist of semitransparent<br />
clear-coats applied on brushed or<br />
transparent lacquered aluminium surface,<br />
highlighting the natural character of aluminium<br />
substrate material, and re-creating the<br />
appearance of stainless steel in the process. The<br />
pre-coat finish also minimises shade variation<br />
between panels and we worked with the project<br />
specifiers and installers to ensure consistency of<br />
grain direction at Janet Nash House to guarantee<br />
high aesthetic detailing.<br />
The panels were fitted by installer Topside, in<br />
between vertical and horizontal aluminium<br />
anodised fins to create a sheer façade, whilst<br />
giving a nod to the company’s core product range<br />
with the ‘coaxial’ pattern. The cladding panels<br />
were fixed between the fins with bespoke<br />
brackets utilising the curtain wall mullions as the<br />
primary structural point.<br />
In contrast to the aluminium finish of the<br />
southern building, the northern block features<br />
large format porcelain panels, which are fitted<br />
throughout as a reference to the traditional use of<br />
ceramics as an electrical insulation material.<br />
The way forward<br />
Where your client is seeking a solution for a large<br />
façade that will make their building look good but<br />
still within a defined budget, I believe pre-coated<br />
aluminium is the way forward. The material<br />
allows longer panels to be produced too, with the<br />
ability to roll form sections in excess of the typical<br />
bench press limitations of PPC options. This<br />
ensures a superior aesthetic and unquestionable<br />
advantages in corrosion resistance, durability and<br />
sustainability. So, if your next project involves a<br />
large façade and your client likes the look of wider<br />
cladding panels then pre-coated aluminium can<br />
provide an effective solution.<br />

ADVERTORIAL<br />
FORM & FUNCTION: NEW CAVITY<br />
SYSTEM FROM SPSENVIROWALL<br />
SPSenvirowall is bringing a new Cavity External Wall Insulation System to market that not<br />
only provides the aesthetic appeal that architects and specifiers want, but also delivers<br />
significant benefits in lightweight construction with building regulation compliance for<br />
buildings up to and over 18 metres, and an extensive range of brick and render finishes.<br />
Leading external wall insulation and façades<br />
supplier SPSenvirowall has announced its<br />
latest fully tested and accredited addition to<br />
its expanding range of innovative systems – The<br />
Cavity System.<br />
Extensively used on lightweight structures, cavity<br />
systems create a drainage void between the<br />
cladding and the sheathed framed structure.<br />
SPSenvirowall Cavity Systems 1 & 2 are the next<br />
generation of this solution.<br />
The speed at which the LSF and insulated<br />
cladding can be erected and weatherproofed<br />
provides extensive benefits to developers, often<br />
removing the cladding from the critical path,<br />
bringing forward the internal trades and thereby<br />
shortening the contract period, thus eliminating<br />
the problems associated with brick and<br />
blockwork construction.<br />
This modern method of construction has proven<br />
extremely popular over recent years and dominates<br />
the build method used for mid to high rise<br />
structures, which is an ideal scenario to specify<br />
and install the new SPSenvirowall Cavity Systems.<br />
The SPSenvirowall Cavity Systems consist of<br />
EuroClass A1 components, which are<br />
mechanically fixed back to the inner sheathing<br />
board to create the designed cavity width, with<br />
either the insulation board fitted directly to the A1<br />
“The Cavity Systems<br />
benefit from a KIWA<br />
BDA certification and is<br />
accepted by leading<br />
building warranty and<br />
insurance providers”<br />
fillets (CS1 system) or a secondary A1 sheathing<br />
board and insulation (CS2 system).<br />
A proprietary base coat render is applied to the<br />
mineral wool insulation boards with a reinforcing<br />
plastic-coated glass fibre mesh prior to the<br />
application of the required finishes.<br />
The Cavity Systems benefit from a KIWA BDA<br />
certification and is accepted by leading building<br />

Sheeting & Cladding<br />
A ROBUST PLAN FOR FRAGILE WORK<br />
Matthew Bailey, Divisional Manager for Inspection and Certification at HCL Safety, looks at<br />
some of the factors that need to be considered when planning work on fragile roofs and<br />
sheeting, and shares some best-practice guidance to ensure workers stay safe.<br />
According to Health and Safety Executive<br />
(HSE) data, falls through fragile surfaces,<br />
particularly fibre-cement roofs and<br />
rooflights, account for 22% of all falls from height<br />
fatal injuries in the construction industry. In 2017<br />
alone, falls accounted for 35 (28%) of all UK<br />
fatalities in the workplace, and over 43,000<br />
nonfatal accidents. The Reporting of Injuries,<br />
Diseases and Dangerous Occurrences<br />
Regulations (RIDDOR) note that over the last five<br />
years, falls from height have accounted for an<br />
average of 37 fatal injuries per<br />
year; over 60% of these deaths<br />
involve falls through fragile<br />
roofs, roof edges, and from<br />
ladders, scaffolds and working<br />
platforms.<br />
What is ‘fragile’?<br />
HSE concerns around surfaces<br />
where rooftop fragility may<br />
present an additional risk to<br />
workers relate to several<br />
common hazards. These include<br />
old rooflights, old liner panels,<br />
non-reinforced fibre cement<br />
sheets, corroded metal sheets, rotten chipboard,<br />
non-load-bearing glass, and aged slates and<br />
tiles.<br />
For safe working practices, the assumption<br />
(echoing HSE guidance) must always be: fragile<br />
until known (or verified via certification evidence)<br />
otherwise. When planning access, competent<br />
persons – in conjunction with the building owner<br />
or facilities manager – should recognise and<br />
record when and where a roof may be fragile. The<br />
rise in use of rooflights on buildings creates<br />
particular challenges. Some designs may, over<br />
several years of weathering and exposure to UV,<br />
Above: Latchways walkSafe raised rooflight<br />
covers.<br />
start to lose their structural strength. Certain<br />
rooflights are manufacturer-certified to be safe to<br />
walk on; but, since sunlight can degrade many<br />
substrates over time making them brittle, this<br />
loadbearing capability is only certified for a<br />
defined period of UV exposure. In contrast, many<br />
other rooflight manufacturers do not warrant this<br />
capability, and so their rooflights must always be<br />
deemed fragile. Remember, too, that rooflights<br />
may be difficult to see clearly in certain light<br />
conditions.<br />
Consider all options<br />
When preparing to<br />
undertake routine<br />
maintenance like cleaning or<br />
repairs at height, avoiding or<br />
eliminating risk is always<br />
the preferred option. Is there<br />
really a need to work on or<br />
near the fragile surface? Is<br />
there another access<br />
method, such as a cherrypicker,<br />
that could provide<br />
the necessary access to the<br />
work area in a more<br />
controlled environment? Alternatively, can the<br />
work be completed from the underside of the roof,<br />
perhaps via a tower inside the building? Some<br />
rooflights, for example, are designed to be taken<br />
out from the underside of the roof when they need<br />
to be replaced due to degradation or age.<br />
If there is no alternative but to access the roof,<br />
fragile areas and the roof edge should, if possible,<br />
be protected. For example, the surface can be<br />
covered with a protective system, guard rails or<br />
scaffolding can be erected. Where workers need<br />
to manoeuvre around rooflights, for example set<br />
within a parapet, safety netting can be put in<br />
place underneath in addition to a fall arrest<br />
system to mitigate a fall due to collapse. In this<br />
scenario, in the event of an accident, a clear<br />
rescue plan also needs to be in place.<br />
Special protection measures<br />
In terms of equipment to protect workers at height,<br />
HCL installs a range of guardrails, fall arrest<br />
systems and rooflight covers manufactured by MSA<br />
Safety which can help to prevent workers from<br />
falling through a fragile rooflight in the event of an<br />
accidental trip or fall.<br />
It’s important to remember, however, that all<br />
equipment specified and how it is installed is<br />
always subject to the specific nuances of<br />
individual projects and roof surfaces. When it<br />
comes to fall protection there’s no such thing as a<br />
‘one size fits all’ approach. To help ensure that the<br />
very best and safest solution for the job at hand is<br />
put in place, installers should always be consulted<br />
at the earliest stage possible.<br />
Learn more. Stay safer.<br />
As a company, we are committed to educating<br />
customers and raising awareness of the unseen<br />
hazards that fragile roofs pose during works. For<br />
example, guard rails may be in place to allow for<br />
gutter cleaning, but there may be no rooflight<br />
protection for workers when traversing into the<br />
central roof area. One of the most effective<br />
opportunities to highlight these dangers is during<br />
competency training, and I’m proud to say HCL<br />
competency training for working at height<br />
specifically deals with fragile roof risks. Never<br />
forget: awareness saves lives.<br />

BIG HIGHS AT LOWER MILL<br />
The Lower Mill Estate, a development of holiday homes in the Cotswolds, offers holiday homemakers the<br />
best in bespoke, energy efficient properties thanks to the Kingspan TEK Building System.<br />
The diverse selection of residential properties have benefited from the Kingspan TEK Building System’s scope<br />
for individual design and off-site construction, which has improved construction efficiency. Lower Mill Estate,<br />
constructed by Conservation Builders, is a community of beautiful holiday homes which has continued to<br />
produce exemplary models of sustainable construction with each new phase of development. The Habitat First Group’s vision was to create a residential<br />
nature reserve that would provide security and the freedom to escape the demands of urban life. The resulting development, immersed in the idyllic woodlands<br />
of the Cotswolds, offers residents tranquillity and relaxation through fully customisable, energy efficient properties. The Kingspan TEK Building System has<br />
enabled clients to enjoy a truly bespoke experience, where they can be involved in the very early stages of designing their property. The latest phase of the<br />
ongoing development makes use of Kingspan TEK panels for the walls and roofs of the new units. The Kingspan TEK Building System, which comprises a highperformance<br />
insulation core sandwiched between two layers of OSB/3, was selected as it allowed a high level of design flexibility and exceptional out-of-thebox<br />
fabric performance, as well as creating minimal site waste as kits are designed and cut off-site. www.kingspantek.co.uk<br />

CUTTING OUT THE WASTE<br />
With statistics regularly quoted about the amount of waste we are all sending to landfill, businesses are looking to<br />
play their part in reducing waste and operating more efficiently.<br />
As such, Freefoam has recently helped Key Partnership Homes do exactly this at their new site at Caleb Close, Luton.<br />
Freefoam supplier Willmott’s of Reading identified during the specification process that the standard five-metre cladding<br />
board would be uneconomical and an inefficient use of materials. George Petts, Willmott’s Business Development<br />
Manager, explained “With many of the units requiring three metre lengths we quickly estimated that a six-metre cladding<br />
board would work much better for this development and considerably reduce waste. We work closely with Freefoam and<br />
with the volumes specified for this site they were happy to manufacture this bespoke order.”<br />
The first 25 properties of a 224-unit site have now been completed, featuring Freefoam Fortex embossed cladding and white roofline range. The mix of<br />
affordable rent and shared ownership tenures, built on behalf of Paradigm Housing Group, features the popular Double Shiplap board in Argyll Brown on both<br />

Fire Safety<br />
FIRE SAFETY REGULATIONS –<br />
YOUR QUESTIONS ANSWERED<br />
Rob Firman, Technical and Specification Manager at Polyfoam XPS, answers frequently<br />
asked questions relating to fire safety regulations and flat roofs.<br />
1What document should I refer to for fire<br />
regulations? National Building Regulations<br />
in the UK regulate fire safety. Guidance on<br />
complying with the regulations is set out in<br />
accompanying documents, published by the<br />
Government of each country. The aim of each<br />
country’s regulations are all broadly the same,<br />
but solutions presented in the guidance<br />
documents may vary.<br />
England and Wales each have their own version of<br />
Approved Document B, Volumes 1 and 2. In<br />
Scotland the guidance is found in Section 2 of the<br />
Technical Handbooks, while in Northern Ireland it is<br />
Technical Booklet E.<br />
2What does the guidance cover? The<br />
guidance covers external and internal fire<br />
spread, as well as access for fire and<br />
rescue services, means of escape, and the fire<br />
performance of internal linings. Solutions for any<br />
given project will differ depending on the building<br />
type, its use and occupancy, layout, height and<br />
construction, as well as the distance from<br />
surrounding buildings.<br />
When using construction<br />
products to comply with the<br />
regulations, contractors should<br />
be aware of the reaction to fire<br />
performance of individual<br />
components, and the fire<br />
resistance of a complete element<br />
build-up or system.<br />
3What is reaction to fire? Reaction to fire is<br />
a measure of how a product behaves when<br />
exposed to a fire, and how it contributes to the<br />
fire as it decomposes as a result of that exposure.<br />
“BS 6229:2018 provides<br />
useful guidance and<br />
depending on the level<br />
of complexity, advice<br />
may also be sought<br />
from a fire engineer or<br />
other specialist”<br />
Left: Rob Firman, Polyfoam XPS.<br />
Products are classified according<br />
to EN 1350. From best to worst<br />
performing, the Euroclass<br />
system is: A1, A2, B, C, D, E<br />
and F. For classifications from<br />
A2 to E, a designation for the<br />
production of smoke and/or flaming<br />
particles are added.<br />
European classifications should be the standard<br />
method of declaring performance, but it remains<br />
common to see national designations used, based<br />
on testing to BS 476-6 and -7.<br />
4What is fire resistance? Fire resistance<br />
has three aspects, all measured by the<br />
number of minutes that elapse during<br />
standard tests. ‘Resistance to collapse’ (R) applies<br />
to loadbearing elements only, ‘resistance to fire<br />
penetration’ (E) is also referred to as integrity, and<br />
‘resistance to the transfer of excessive heat’ (I) is<br />
otherwise known as insulation.<br />
A construction element may need to meet all three<br />
aspects, in which case the performance would be<br />
written REI 30 (or 60, 90 or 120, depending on the<br />
period of resistance achieved/required).<br />
‘EI’ relates to an element that is not loadbearing,<br />
and sometimes E alone is required – again, both<br />
are followed by the number of minutes.<br />
“Applying general<br />
principles to buildings<br />
where specific<br />
provisions are required<br />
risks compromising<br />
fire safety”<br />
80 TC SEPTEMBER <strong>2019</strong>
“Fire safety is a sensitive topic and<br />
a lack of confidence about how<br />
materials work individually and<br />
when combined in a system is<br />
understandable”<br />
5How is resistance to fire spread declared for roofs? A roof’s<br />
resistance to external fire exposure, in terms of fire spread across the<br />
surface and penetration through the construction, is classified<br />
separately in accordance with EN 13501-5. A roof can be rated one of the<br />
following, from best to worst: BROOF(t4), CROOF(t4), DROOF(t4), EROOF(t4), or<br />
FROOF(t4).<br />
EN 13501-5 refers to four separate roof tests, detailed in ENV 1187. The (t4)<br />
refers to the use of test 4, which is the only one sufficiently rigorous to<br />
demonstrate compliance with UK fire safety requirements. The performance<br />
rating of a roof typically dictates how far from a boundary or another building<br />
the particular construction may be used.<br />
6How should fire performance declarations be applied? Fire safety<br />
is a sensitive topic and a lack of confidence about how materials work<br />
individually and when combined in a system is understandable.<br />
The more complex the building, the more specific the requirements in terms of<br />
fire safety and performance. Applying general principles to buildings where<br />
specific provisions are required risks compromising fire safety.<br />
Where flat roofs are concerned, BS 6229:2018 provides useful guidance and<br />
depending on the level of complexity, advice may also be sought from a fire<br />
engineer or other specialist. Some projects, meanwhile, require consultation<br />
directly with the local fire service.<br />
‘All Inverted Roof<br />
Insulation achieves the same U value at a given<br />
thickness...’<br />
In the past this may well have been the case. There were fewer<br />
manufacturers, using similar blowing agents and much less<br />
challenging U value targets.<br />
However, environmental pressures led to a required change in<br />
blowing agent technology from CFC’s and HCFC’s to Recycled CO 2 ,<br />
which although greener and cleaner led to higher lambda values and<br />
consequently greater thickness required to achieve the same U values<br />
as before.<br />
Pressure continued, with ETAG 031 and other regulatory legislation<br />
leading to the assessment of the effects of rainwater cooling and freeze<br />
thaw cycles. The industry began looking at design lambdas which<br />
addressed these issues and through new technologies such as the<br />
introduction of water reducing layers, the lamination of thinner more<br />
<br />
<br />
<br />
<br />
<br />
<br />
addition of new constituents such as graphite manufactures, over time,<br />
achieved thinner solutions.<br />
Which leads us to the latest and perhaps greatest innovation in<br />
Extruded Polystyrene (XPS) technology to date. Ravago, have launched<br />
XENERGY TM ULTRA TM . Developed to deliver improved thermal<br />
<br />
<br />
<br />
<br />
<br />
<br />
<br />
<br />
<br />
<br />
<br />
<br />
<br />
<br />
<br />
thicknesses of the past.<br />
So what does that mean to our original question? Does all Inverted<br />
Roof Insulation still achieve the same U value at a given thickness?<br />
If we look at 0.15 W/m 2 <br />
<br />
<br />
<br />
TM<br />
<br />
<br />
<br />
TM ULTRA<br />
achieves this target in only<br />
175mm, 30mm thinner than Ravago’s own previously best solution<br />
TM SL) and almost 50mm thinner than most other XPS<br />
Solutions and at 0.1 W/m 2 TM ULTRA<br />
TM is only 260mm<br />
(2x130mm), 60mm thinner than most alternative XPS solutions and up<br />
to 95mm thinner than most EPS (Expanded Polystyrene) Solutions.<br />
Then the answer is now emphatically NO!<br />
With a design lambda of 0.028 W/mK and U value targeted<br />
thicknesses <br />
<br />
TM ULTRA TM has radically changed<br />
how we look at product comparisons. We can no longer make price<br />
comparisons based on cost £/m 3 , we now need to look more closely at<br />
price £/m 2 of any product to achieve any given U value!<br />

Construction Tapes<br />
TALE OF THE TAPE: SEAL THE DEAL<br />
Construction tapes: accessories or essentials? The experts at A. Proctor Group discuss...<br />
The phrase “a chain is only as strong as its<br />
weakest link” is completely appropriate to<br />
use when describing a building envelope<br />
that is designed for longevity and constructed<br />
with integrity.<br />
Considering the small format size and the total<br />
relative amounts used on a building site<br />
compared to other building materials, the<br />
importance of construction tapes are easily<br />
overlooked. Often classified as an accessory, tapes<br />
can mistakenly be thought of as an optional,<br />
interchangeable or a “nice-to-have-but-notnecessary”<br />
item. In fact, because tapes are used<br />
for things like sealing the connections between<br />
insulation boards and building membranes –<br />
arguably the weakest points of any building<br />
envelope – tapes should be thought of as an<br />
indispensable component of the total building<br />
system.<br />
Uncontrolled air movement through poorly sealed or<br />
punctured membranes and gaps between rigid<br />
insulation boards reduces the energy performance<br />
and internal comfort of new and refurbished<br />
buildings alike. Whether or not the building uses the<br />
highest specification membranes and modern<br />
insulation may not matter if air leakage pathways<br />
are not properly sealed off. Heat will simply bypass<br />
these materials and their energy and thermal<br />
benefits will not be fully realised as a result.<br />
Not all tapes are created equal<br />
If remembering to include tape into a construction<br />
specification is important, then making sure to<br />
choose the right tape for the job is absolutely<br />
essential. Construction tapes should complement<br />
the performance of the system they support, be<br />
strong enough for the job, adhere well to the specific<br />
surface they are applied to, and tolerate the shortand<br />
long-term environmental conditions of the<br />
building site without substantial loss of function.<br />
Choosing the right tape for the application can make<br />
the difference between success and failure of a<br />
building system.<br />
Ideally, there would be one product that could be<br />
used in all areas of a building site that requires<br />
tape. Unfortunately, there isn’t a single tape solution<br />
that is practically or technically viable to do every<br />
kind of taping job well. This means the contractor<br />
will have to be knowledgeable of the role tape plays<br />
in many different taping scenarios.<br />
Some of the questions contractors should ask when<br />
deciding on which tape to use can generally be<br />
grouped into two categories:<br />
“What is the function of the tape?”<br />
• Sealing gaps? Fixing other materials temporarily<br />
or permanently?<br />
• Does the tape need to be airtight, breathable or<br />
reflective?<br />
• Does the tape need to be reinforced, transparent<br />
or flexible?<br />
• Which material edges are being sealed i.e. do you<br />
need single-sided or double-sided tape?<br />
“Where is the tape being used?”<br />
• Will the tape adhere to the substrate? Is a primer<br />
required?<br />
• What is the expected working temperature and<br />
humidity range?<br />
• Does the tape need to have water or UV<br />
resistance?<br />
• Does the tape need to be solvent or VOC-free (i.e.<br />
interior applications)?<br />
Tape System Component Collection:<br />
With so many options out there, it is handy to have<br />
a collection of high-performance tapes all in one<br />
place. To enable contractors meet the guidelines set<br />
out in Building Regulation documents and help them<br />
A Proctor offers a range of tapes.<br />
make the right decisions regarding tapes, the A.<br />
Proctor Group supplies a wide range of tapes that<br />
complement building envelope systems. Designed<br />
specifically in response to the evolving demands of<br />
the industry, their collection of construction tapes<br />
ensures the performance, resistance and reliability<br />
of the full gamut of internal and external<br />
construction systems.<br />
• Wraptite Tape: Vapour permeable and airtight for<br />
external membrane detailing and sealing the<br />
exposed joints of rigid insulation.<br />
• Flextite Tape: Scrim-reinforced elastic tape for<br />
internal and external applications with high<br />
adhesive strength, water resistance and UVstability.<br />
• Procheck Multilap Tape: Solvent-free scrimreinforced<br />
double-sided vapour barrier tape with<br />
easy release liner and high adhesive coating weight<br />
(can bond to rough surfaces).<br />
• Reflectafoil Tape: Air- and vapour-tight flameretardant<br />
30um aluminium foil tape used for sealing<br />

OLYMPIC WIN FOR OPTIM-R<br />
The Kingspan OPTIM-R Balcony and Terrace System has been installed as part of the award-winning Here East<br />
development, a stunning repurposing of the press and broadcasting centres at the Queen Elizabeth Olympic Park.<br />
Here East provides over 110,000m² of flexible studio, work and retail spaces. The design adds warmth and creativity to<br />
the once windowless, monolithic façade of The Broadcast Centre. The building has been opened up with a new<br />
projecting unitised curtain-wall system and recessed balconies helping to add depth and interest to the building.<br />
Operatives from Kingspan Insulation’s<br />
OPTIM-R design service ensured the optimal<br />
ratio of OPTIM-R VIPs to infill panels.<br />
Lakesmere, now owned by Kaicer Building Envelope Solutions, were appointed to deliver the curtain-walling which wraps three sides of the building. The design<br />
called for three large recessed balconies running up to 13 metres in length. A pedestal floor construction was chosen for these areas and to ensure the space below<br />
was effectively insulated, whilst also maintaining a level transition from the adjoining space, the Kingspan OPTIM-R Balcony and Terrace System was chosen.<br />
Unlike conventional insulation materials, Kingspan OPTIM-R panels feature a vacuum insulation core with an innovative microporous structure. This design allows<br />
them to achieve a declared thermal conductivity of 0.007 W/m∙K – up to five times lower than commonly used insulation materials. Rigid insulation infill panels of<br />
the same thickness are also included within the system. These are fitted around the perimeter of the balcony and can also be cut to allow for penetrations through<br />
the insulation layer or to fill spaces between the Kingspan OPTIM-R vacuum insulation panels (VIPs). www.kingspaninsulation.co.uk/optim-r<br />
INSULATION MOVE FOR AVONSIDE<br />
Avonside Group has acquired the BillSaveUK Housebuilding Insulation Division.<br />
The acquisition means Avonside’s existing insulation operation will now be incorporated into the new<br />
Division. Tony Burke, Chief Executive of Avonside Group, explained: “BillSaveUK have garnered a<br />
reputation of being the country’s leading installers of cavity wall insulation and loft insulation, and have<br />
built fantastic relationships with their loyal customer base. As part of Avonside Group’s long-term growth<br />
strategy, we are pleased to have the opportunity to build on BillSavesUK’s legacy and are looking forward<br />
to delivering the high standard of service customers have come to expect.” www.avonsidegroup.co.uk<br />
SIPS’ STRUCTURAL STRENGTHS<br />
The Kingspan TEK Building System has been used to construct five luxury villas at the Porth Veor<br />
Manor Hotel near Newquay – providing the perfect seaside spot for holiday makers.<br />
Porth Veor Manor Hotel: “In order to create a curve, the roof<br />
panels were spanned horizontally and faceted then<br />
battened and lined with plywood.”<br />
The Kingspan TEK Building System of SIPs was specified for the project for a variety of reasons, as Mike<br />
Burke, from Sip Hus, explained: “The design of the units, their location, size and performance<br />
requirements meant that the Kingspan TEK Building System was the best choice for the structural shells.<br />
The excellent thermal performance of the panels allowed us to maximise the internal spaces within the<br />
given footprint without having to compromise on thermal efficiency.” www.kingspantek.co.uk<br />
FABRIC GAINS FOR MILL PROJECT<br />
Kingspan Kooltherm K7 and K107 Pitched Roof Board have helped transform a former Victorian<br />
mill into CAT B office space for Manchester Metropolitan University.<br />
Kingspan Kooltherm K7 and K107 Pitched Roof Board can<br />
achieve thermal conductivities as low as 0.020 W/m·K<br />
and 0.018 W/m·K, respectively.<br />
The design team for 6 Great Marlborough Street prepared the fit-out using the Royal Institute of<br />
Chartered Surveyor’s SKA Rating environmental assessment method – targeting a Silver rating<br />
certificate. As part of this process, they identified an opportunity to upgrade the thermal performance<br />
of the poorly insulated pitched roof. To minimise heat loss through the roof, a construction combining<br />
Kingspan Kooltherm K7 and K107 Pitched Roof Board was installed. www.kingspaninsulation.co.uk<br />

to Dust<br />
EXTRACTION PLAN!<br />
The experts at EJOT UK discuss a new solution to protect<br />
against airborne concrete dust and debris contamination.<br />
The airborne distribution of dust and debris<br />
created from a variety of construction site<br />
activities has become a priority focus for<br />
the UK Government’s Health and Safety Executive<br />
(HSE). For example, the HSE’s CIS69 document<br />
provides guidance on choosing, using and<br />
maintaining on-tool extraction to control<br />
construction site dust. This dust may contain<br />
some very fine dust called respirable crystalline<br />
silica (RCS) and exposure to<br />
RCS dust can be the cause<br />
of varying levels of health<br />
1<br />
problems – many serious.<br />
This and other documents<br />
also highlight the legal<br />
responsibilities for<br />
employers to either prevent<br />
or adequately control<br />
‘worker exposure’ to high<br />
levels of dust created by a<br />
variety of tasks that include<br />
cut-off saws, grinders,<br />
breakers and sanders.<br />

the abbreviation means “Special Direct System”,<br />
whilst in the UK “Slotted Drive System” is also<br />
commonly used. Whichever version you favour,<br />
the SDS design utilises these slots to allow the<br />
drill’s hammer action to thrust the drill bit<br />

EJOT has produced this handy infographic that<br />
talks through the process of its vortex-SDS tool.<br />
of the HSE’s focus on airborne<br />
concrete dust contamination.<br />
Working alongside industry<br />
partners, the company has<br />
developed ‘EJOT vortex-SDS’; a<br />
modular drilling system<br />
engineered from high quality<br />
materials, and providing instant<br />
dust-removal drilling, at source.<br />
The modular nature of EJOT<br />
vortex-SDS provides drilling<br />
options from 8 to 20mm<br />
diameter and appropriate depths<br />
up to 440mm, with obvious<br />
replacement and inventory<br />
advantages.<br />
Dust extraction at source<br />
The vented four-cutter design of<br />
each carbide drill tip initiates the<br />
powerful ‘vortex’ dust extraction<br />
force that is created within each<br />
operating component, drawing dust and debris<br />
directly through the system and into the industrial<br />
vacuum cleaner. An integral 16amp socket<br />
connector means that the vortex action is instant<br />
and occurs as soon as the drill is activated and<br />
continues for ten seconds after drilling has<br />
finished.<br />
The removal of dust lessens friction between the<br />
substrate and drill bit, thereby speeding<br />
The vortex-SDS kit comprises:<br />
• 4 x standard carbide tipped drill bits.<br />
• 8mm, 10mm, 12mm and 14mm diameters.<br />
• 70mm, 95mm, 120mm and 145mm<br />
lengths.<br />
• 1 x special drill-to-bit connector.<br />
• 1 x modular extension bar, 220mm length.<br />
• 3 x modular carbide tipped drill bits, 40mm<br />
length.<br />
• Choice of 16mm, 18mm and 20mm<br />
modular diameters.<br />

SPONSORED BY<br />
& Protective Wear<br />
DON’T RISK IT: DRESS APPROPRIATELY<br />
By Peter Dummigan, MD of the Hultafors Group UK, owners of Snickers Workwear.<br />
The Personal Protective Equipment at Work<br />
Regulations 1992 stipulate that: ‘Every<br />
employer shall ensure that suitable<br />
personal protective equipment is provided to his<br />
employees who may be exposed to a risk to their<br />
health or safety while at work, except where and<br />
to the extent that such risk has been adequately<br />
controlled by other means which are equally or<br />
more effective.’<br />
What does this mean for Workwear?<br />
Workwear as a form of PPE generally includes<br />
safety glasses, face shields, hard hats, safety<br />
shoes, insulating (rubber) gloves, plus clothing<br />
more commonly known as Protective Wear.<br />
As working clothes go, there’s a big difference<br />
between conventional Workwear and specialist<br />
Protective Wear. Over the years, workwear has<br />
evolved to make your working day more<br />
comfortable and efficient, with built-in<br />
functionality for tools and fixings, as well as<br />
protection against cold, rain and the effects of<br />
warm weather.<br />
Protective Wear, which can have one or more CE<br />
(European Conformity) marks, is significantly<br />
more specialist and has been developed to<br />
protect the wearer from serious risks such as<br />
heat, flames, mechanical hazards, electric arcs,<br />
hazardous chemicals – and even the weather!<br />
Protective Wear has to be certified against<br />
Regulation (EU) 2016/425, which determines the<br />
fundamental safety and protection requirements<br />
with which clothing has to comply.<br />
The product certification process for this<br />
regulation includes the independent testing and<br />
accreditation of a product’s functionality and<br />
performance. This is carried out against a predetermined<br />
set of standards and technical<br />
specifications that are designed to ensure a<br />
user’s safety and security.<br />
It’s a complex process that requires a<br />
considerable investment in time, resources and<br />
money on the part of the product developer who,<br />
on successful completion, is required to affix the<br />
CE mark to the product as a visible indication of<br />
conformity with the fundamental accreditation<br />
requirements.<br />
The types of testing vary from one certification to<br />
another. For protective wear, the higher the<br />
protection category, the more complex the testing<br />
process, which for protective wear, primarily<br />
focuses on garment fabrics.<br />
For instance, Snickers Workwear’s new,<br />
ergonomically designed ProtecWork clothing<br />
manufactured for welding and allied processes is<br />
tested to measure the ability of the garment to<br />
protect against ignition from various heat<br />
sources, such as open flames, molten iron splash<br />
and contact heat. The ProtecWork clothing that<br />
safeguards against the thermal hazards of an<br />
electric arc is tested and certified to eliminate<br />
second-degree burns in the event of an electric<br />
arc flash.<br />
Risk environments and CE protection<br />
categories<br />
In order to meet the protective requirements of a<br />
specific risk area, protective wear is divided into<br />
three categories – the higher the category<br />
number, the higher the level of protection.<br />
Category I covers exposure to minimal risks, and<br />
for this category there are CE standards such as<br />
EN 343 (rain protection) and EN 14058 (cold<br />
protection).<br />
Category II includes exposure to medium risks, for<br />
instance EN 20471 for high visibility clothing.<br />
Category III covers exposure to serious risks,<br />
which include major hazards such as electric<br />
arcs and molten metal splashes or liquid<br />
chemicals.<br />
CE protection for selected categories for<br />
ProtecWork Protective Wear<br />
EN 14404 - Knee protection.<br />
This standard stipulates the size, force<br />
distribution, penetration resistance and user<br />
testing of kneepads. “We use Type 2 knee<br />
protectors for our products” explained Peter<br />
Dumigan. “The knee protection is integrated with<br />
the trousers, which means that wherever you go,<br />
your knees are always protected. The knee<br />
protectors and the trousers are co-certified,<br />
ensuring safe and secure protection.”<br />
EN 342 - Protective clothing against cold<br />
EN 342 specifies the requirements and<br />
performance of clothing designed to protect<br />
against cooling of the body in cold environments.<br />
Wearing several layers is a great way of<br />
increasing insulation and enhancing protection<br />
against the cold. A layered outfit also makes it<br />
easy to adjust to rapid temperature changes.<br />
Remember that sweating should be avoided<br />
during continuous cold exposure, since moisture<br />
absorption will progressively reduce insulation.<br />
EN 343 - Protective clothing against rain<br />
Rain doesn’t only make you wet, but also cold,<br />
hampering your work performance. EN 343<br />
specifies the performance and requirements of<br />
clothing protecting against rain and vapour. The<br />
standard defines the water penetration resistance<br />
of the garment’s fabric and seams and water<br />
vapour resistance.<br />
EN ISO 20471 - High visibility clothing<br />
EN ISO 20471 specifies requirements for clothing<br />
capable of signalling the user’s presence visually.<br />
Performance requirements are included for colour<br />
and retro reflection as well as for minimum areas<br />
and for the disposition of fluorescent and<br />
reflective materials.<br />
88 TC SEPTEMBER <strong>2019</strong>
EN ISO 11612 - Protective clothing against<br />
heat and flame<br />
EN 11612 specifies performance for clothing<br />
designed to protect from heat and/or flame (not<br />
including protection for firefighters and welders).<br />
The standard indicates protection against ignition<br />
from various heat sources – flames, molten<br />
splashes and contact heat for instance. To ensure<br />
full protection, the head, neck, hands and feet<br />
must be covered with other approved protective<br />
clothing.<br />
EN ISO 14116 - Protective clothing against flame<br />
EN 14116 specifies the performance of protective<br />
clothing for workers exposed to occasional brief<br />
contact with open flames with no other thermal<br />
risks.<br />
EN 388 - Protective gloves against mechanical<br />
risks<br />
This standard applies to all kinds of protective<br />
gloves in respect of physical and mechanical<br />
aggressions caused by abrasion, blade cut, tear,<br />
puncture and, if applicable, impact.<br />
EN407 - Protective gloves against thermal<br />
risks<br />
This standard specifies thermal performance for<br />
protective gloves against heat and/or fire.<br />
EN 511 - Protective gloves against cold<br />
This standard applies to any gloves to protect the<br />
hands against convective and contact cold down<br />
to –50 °C.<br />
Avoid injury – work safely, ensure your<br />
whole outfit offers proper protection<br />
“Working in high-risk environments involves, as<br />
the name implies, high-risk levels”, explained<br />
Peter Dumigan. “So it’s vital that you – the buyer<br />
– carry out a proper risk assessment from which<br />
you’ll be able to choose the right protective wear<br />
to ensure the safety and well-being of you and<br />
your employees on site.<br />
“To be able to properly identify what protection<br />
you need, you have to know what risks you, your<br />
employees or your workmates face. Importantly,<br />
each working situation will have its own required<br />
minimum protection depending on the risk<br />
situation.<br />
“Never assume that a Category I garment will<br />
protect against the more serious hazards and<br />
risks defined in Category III. It won’t and you’ll be<br />
putting your employees at serious risk if you think<br />
it will.<br />
“That means understanding the hazards and<br />
risks of a specific working environment or<br />
knowing the risk level before starting work, and<br />
therefore providing appropriate clothing and PPE<br />
accessories.”<br />

After conducting research amongst their customers, 46% of respondents stated they have had their tools stolen, and<br />
39% said they’ve had them stolen at least twice. When it comes to protecting their tools, the majority of tradespeople<br />
said they take measures to keep their tools safe, with the most popular methods being ‘removing tools from the van<br />
overnight’ (26%) and ‘installing CCTV’ (18%). There was also a strong feeling reflected by 56% who believe more<br />
should be done to help protect tradespeople’s tools and vans. One way in which Screwfix is showing its support is<br />
through tool marking. Local authorities are hosting events across Screwfix’s 630 stores to help prevent tool theft,<br />

to be exciting, you want them to fit<br />
easily and to last - year after year.<br />
We’ve made sure all our products<br />
will do just that. They’re tested<br />
in simulated weather conditions<br />
worse than anything you’re likely<br />
to find in the UK. Which is why<br />
we can guarantee them against<br />
manufacturing defects for ten years<br />
and why, once you’ve fitted Klober,<br />
you can relax.<br />
Don’t trust luck, trust Klober.<br />

All the benefits<br />
of lead but<br />
without the wait<br />
Wakaflex<br />
Save time with Wakaflex lead-free<br />
flashing. 50% faster to apply than lead.<br />
Wakaflex looks like lead, is weathertight<br />
like lead and lasts like lead. It’s been<br />
tried and tested to ensure it’ll stand up<br />
to the worst of British weather (unlike<br />
many other low-cost lead alternatives)<br />
and comes with a 20-year guarantee.<br />
But it’s non-toxic, self-welding, and won’t<br />
be stolen. It could be just what you’ve<br />
been waiting for. It’s fast. And lasts<br />
