Competency has been a key word in construction for those throughout<br />

the supply chain over the last few years, and it’s clear it’s going to be<br />

central to decision-making when it comes to planning, designing and<br />

constructing projects moving forward.<br />

Like all those operating across construction, the spotlight is going be on<br />

roofing contractors and operatives to ensure best practice. With this in<br />

mind, in this issue we continue our focus on Safe2Torch. On page 14, as the<br />

NFRC continues to mark five years since the launch of the Safe2Torch<br />

initiative, Gary Walpole looks back on the major school fires in 2016 that<br />

brought about the sector’s greater focus on best practice for hotworks and<br />

correct use of gas torches, which then led to the Safe2Torch guidance as we<br />

know it today. As Gary explains: “The focus of the Safe2Torch campaign is<br />

ensuring that all duty holders, including the client, designer and contractor,<br />

have an understanding of the factors that contribute to fire risks, as well as<br />

the safeguards needed to mitigate these risks.” But as Gary explains,<br />

there’s still much more work to do, and we’ll be looking more closely at<br />

Safe2Torch and how the sector can ensure best practice and a wider reach<br />

for this important guidance in future issues of Total Contractor.<br />

Elsewhere in this issue, Jason Wright explains how we can ensure roofing<br />

isn’t a last resort for school-leavers (page 16); Sam Tebbs of Marley outlines<br />

how roofers can get ahead of the game when it comes to Part L (page 20);<br />

Iain Macpherson of TaperedPlus talks flat roof failures and how to eliminate<br />

ponding (page 40); and Bradley Hirst of Knauf Insulation provides his 6 top<br />

tips for a successful roof insulation installation on page 56.<br />

So read on for all this and much, much more!<br />

of DMG Services Group, the DMG Academy of<br />

Roofing is located on Strathclyde Business Park<br />

and offers Roof Slating & Tiling Courses, but<br />

having noticed the poor standard of leadwork on<br />

sites he was working on and the lack of lead<br />

training provision in the area, Darren took the<br />

decision utilise his facility for leadwork training to<br />

upskill and raise standards in Scotland.<br />

Darren explained: “By offering these courses, we<br />

see a great opportunity to help roofing and<br />

leadwork in general, but to help it particularly in<br />

Scotland – if we offer the Basic Courses, we<br />

capture the attention of roofers and we can send<br />

them on for the Intermediate and Advanced<br />

courses, so we’re working with the LSTA to raise<br />

standards and promote best<br />

GRO FOCUSES ON BEST PRACTICE WITH NBS PARTNERSHIP<br />

The Green Roofing Organisation (GRO) has<br />

announced a new partnership with NBS, the<br />

platform providing construction specification<br />

information used by architects, engineers and<br />

other building professionals.<br />

The organisations say the collaboration will help<br />

specifiers access the most accurate specification<br />

guidance to ensure the many environmental and<br />

health benefits that Green Roofs provide are<br />

realised.<br />

A key focus of GRO is ensuring that the expert<br />

knowledge its members have gained is shared<br />

with designers. Through this collaboration, GRO<br />

says its wealth of expertise covering different<br />

systems including, biosolar roofs and blue roofs<br />

will now be shared with NBS users, enabling<br />

them to benefit from these systems and ensuring<br />

best practice with regards to specification and<br />

installation.<br />

Commenting on the partnership, Sascia Elliott,<br />

Head of Partnerships at NBS, said: “Architects<br />

and landscape designers have been key in the<br />

transition of green roofing from niche to<br />

mainstream. Yet due to the rapidly evolving<br />

nature of the solutions available, it was crucial<br />

that we had access to experts in the field, who<br />

have real world knowledge of the realities of<br />

specifying, installing and maintaining these green<br />

roofs, along with the latest guidance around<br />

biosolar and blue roofs. Working with GRO will<br />

ensure that specifiers can be confident they’ve<br />

access to the latest and most trusted guidance.”<br />

Mark Harris, (pictured) Chair of GRO, explained:<br />

“NBS provides key resources for the design and<br />

specification of buildings<br />

in the UK, including the<br />

specification of roofing<br />

systems. Our<br />

collaboration with NBS has<br />

provided the opportunity to<br />

demonstrate our extensive knowledge and help to<br />

educate construction professionals. The<br />

organisation supports them in the specification of<br />

high quality green, blue and biosolar roofs, that<br />

positively contribute to climate change<br />

adaptation and mitigation.”<br />

GRO has developed and continued to update its<br />

Green Roof Code of Best Practice. The<br />

organisation has also created a professional<br />

installers qualification (L2 and L3) with Lantra,<br />

which has been available since 2019.<br />

MCS DATA: SOLAR<br />

CONTINUES TO SOAR<br />

New data from MCS, the national standards<br />

body for<br />

renewables, shows<br />

solar photovoltaic<br />

(PV) panels<br />

installed on<br />

British homes<br />

equated to 3GW<br />

of electricity for the<br />

UK grid for the first time ever last year.<br />

MCS says this represents £20billion, the<br />

estimated cost of construction for the Sizewell<br />

C nuclear power plant, which will have an<br />

energy output of 3.2GW. With installation<br />

numbers soaring, the MCS installation<br />

database predicts that solar PV will surpass<br />

the Suffolk reactor’s output by spring this year.<br />

The data also shows that, in 2021, 61,455 UK<br />

properties had solar panels installed – an<br />

increase of 71% on the previous year<br />

(35,841*). This takes the total number of<br />

‘sunny roofed’ residential properties to one<br />

million, according to Solar Energy UK.<br />

Ian Rippin, Chief Executive of MCS, said: “The<br />

rate at which domestic solar PV systems are<br />

being installed is hugely positive and shows<br />

continued confidence in home-grown energy.<br />

Consumers are increasingly keen to invest in<br />

low-carbon technology for the home because<br />

installation costs are falling as energy prices<br />

soar. Behavioural changes brought about during<br />

the pandemic also continue to influence the<br />

purchasing decision. Every homeowner should<br />

feel empowered to find the right renewable<br />

energy technology to power their homes,<br />

particularly given the long-term economic and<br />

environmental benefits. These include saving<br />

money and the environment, adding value to<br />

their homes, and supporting the businesses<br />

that are certified to install them.”<br />

APPRENTICE COMP IS OPEN FOR ENTRIES!<br />

BMI is calling all roofing apprentices and<br />

students studying towards their qualified<br />

roofer status to enter this year’s BMI<br />

Apprentice of the Year competition!<br />

The annual Apprentice of the Year competition is<br />

part of BMI’s commitment to support and nurture<br />

the future of roofing, as the contest seeks to find<br />

the UK’s most promising apprentices and future<br />

leaders in roofing.<br />

Every year, BMI invites roofing apprentices from<br />

across the country to come together at the annual<br />

Apprentice of the Year competition and test their<br />

skills in front of a panel of industry judges. The<br />

winner receives a cash prize of £1000 and the<br />

prestigious title of Apprentice of Year, as well as<br />

three years’ worth of training support from the<br />

BMI Academy.<br />

Last year, following an exciting and challenging<br />

two days, roofing apprentices Jamie Scott of<br />

Bourne-based Sandall Roofing, and Brandon<br />

McGrail-Manning of SPV Group, Walsall, were<br />

declared winners in the Pitched and Flat Roofing<br />

categories respectively.<br />

Brandon explained: “Winning the BMI Apprentice<br />

of the Year means a lot to me, I work with Building<br />

Futures which is a study programme which helps<br />

out young people who haven’t had the best of<br />

backgrounds, I want to bring hope to them and<br />

show them anyone can do it!”<br />

Jamie explained: “Taking part in the Apprentice of<br />

the Year has really opened my eyes to the<br />

opportunities roofing and construction can offer<br />

me. It has also shown me what I can achieve. I<br />

have met a variety of people from all different<br />

backgrounds throughout the competition, and all<br />

of them achieving so much has inspired me to<br />

push myself even harder and further.”<br />

The competition opened for entries on <strong>March</strong> 7th<br />

and judges will be looking at several aspects of<br />

the apprenticeship, from roofing skills to<br />

teamwork, with a focus on business acumen,<br />

presentation, and marketing skills. The<br />

Above: Jamie Scott (left) was crowned BMI Pitched Roofing<br />

Apprentice of the Year 2021, whilst Brandon McGrail-<br />

Manning took home the Flat Roofing trophy.<br />

competition is open to apprentices nationwide in<br />

both pitched and flat roofing, and the closing date<br />

for entries is April 29th.<br />

Held over two days on 20th and 21st July <strong>2022</strong> at<br />

the BMI Academy in Gloucestershire, BMI says this<br />

year’s theme is “Empower” and the company is<br />

looking for apprentices who can demonstrate how<br />

they empower themselves and others by playing<br />

an active role across the roofing community and<br />

beyond. Finalists will be coached during the event<br />

on a range of topics from presentation skills and<br />

social media for business, through to estimating<br />

and making technical assessments.<br />

Entries can be made online and applicants will be<br />

asked to answer questions to highlight their<br />

commitment to their roofing career, the industry<br />

as a whole, and to showcase their future<br />

leadership abilities. Mat Woodyatt, Technical<br />

Training Manager at BMI, explained: “We’re<br />

committed to supporting apprentices and the<br />

future of roofing, through the work at BMI<br />

Academy – our training platform which is open to<br />

roofers and roofing industry professionals at all<br />

stages of their career – as well as our continued<br />

support of colleges and training providers across<br />

the country. BMI Apprentice of the Year is our way<br />

to celebrate apprentices by encouraging them to<br />

showcase and develop their skills and explore<br />

where their career in roofing can take them –<br />

we’re really looking forward to welcoming this<br />

year’s finalists to the BMI Academy in July.”<br />

Five Years of Safe2Torch<br />

HOW TWO SCHOOL FIRES BROUGHT<br />

GAS TORCH SAFETY INTO FOCUS<br />

As we continue our focus on Safe2Torch, Gary Walpole, Safety, Health and<br />

Environment Officer at NFRC, looks back on two school fires that shocked the sector<br />

and brought a greater focus on the safe and correct use of gas torches and hotworks,<br />

ultimately leading to the launch of the Safe2Torch guidance...<br />

In August 2016, there were two major school<br />

fires that took place a week before the start of<br />

the new school year, with the damage from<br />

the fires causing both school buildings to be<br />

destroyed. Both fires were caused by hot works.<br />

The devastation caused in the wake of these two<br />

fires shocked the industry and prompted a request<br />

that the sector work together to tackle the issues<br />

surrounding hot works and the use of gas torches.<br />

This then led to a working group being formed in<br />

late 2016 of both contractors and manufacturers.<br />

It was within this group that it was agreed that a<br />

safety initiative was needed to showcase best<br />

practice, and this where Safe2Torch originated.<br />

Principles of Prevention<br />

The focus of the Safe2Torch campaign is ensuring<br />

that all duty holders, including the client,<br />

designer and contractor, have an understanding<br />

of the factors that contribute to fire risks, as well<br />

as the safeguards needed to mitigate these risks.<br />

An important part of this is that the Principles of<br />

Prevention are implemented throughout the<br />

design, planning and construction phase by all<br />

the relevant duty holders.<br />

By applying these Principles of Prevention, the<br />

working group felt that the fire hazards were best<br />

identified at the specification stage so the fire<br />

risk could either be removed or managed by using<br />

flame-free alternatives.<br />

The end result of this working group was the<br />

launch of the Safe2Torch initiative in 2017, with a<br />

big social media campaign which encouraged<br />

both contractors and manufacturers to sign up to<br />

“There is still<br />

much more<br />

work to do.<br />

Sadly,<br />

Safe2Torch<br />

hasn’t been able<br />

to prevent all roof fires”<br />

and pledge to support the campaign.<br />

Guidance notes and a checklist were created to<br />

provide information on the skills, knowledge and<br />

experience needed to identify and control fire<br />

risks. The Safe2Torch checklist should form an<br />

integral part of the risk assessment and method<br />

statement where gas torches are used. Before<br />

starting any hot works, the checklist should be<br />

completed to highlight high risk areas where<br />

direct-torch application should be avoided.<br />

Following the launch of the Safe2Torch campaign,<br />

feedback was focused on the lack of training<br />

surrounding the safe use of LPG and gas torches.<br />

We therefore focused our efforts on supporting<br />

the contractors working with gas torches by<br />

providing them with a Safe2Torch training<br />

module. This was developed in 2019 and is being<br />

delivered by manufacturers who are best placed<br />

to deliver this as it can easily be incorporated into<br />

their existing operative courses.<br />

Left: Gary Walpole, NFRC.<br />

This training module has also<br />

been introduced as a training<br />

module within the new<br />

Trailblazer Apprenticeship to<br />

ensure new entrants coming into the<br />

industry understand how to use LPG and<br />

gas torches correctly.<br />

Still much more work to be done<br />

However, there is still much more work to do.<br />

Sadly, Safe2Torch hasn’t been able to prevent all<br />

roof fires. For example, there was a roof fire at a<br />

junior school in 2020 which prompted NFRC to<br />

issue a safety alert on the fire risks associated<br />

with so called ‘CLASP buildings’ such as this<br />

school. We also hear of anecdotal evidence that<br />

young people are still entering our industry<br />

without a full awareness of these issues.<br />

Since those devastating fires in 2016, the<br />

industry has really showed its commitment to<br />

understanding the serious issues of fire in<br />

construction, and that it was forward-thinking<br />

enough to be able to do something about it.<br />

However, until there are no more roof fires, there<br />

will always be a need for the campaign and<br />

there’s much more work still to do.<br />

campaign yet, please do so at:<br />

Total Talk: Jason Wright<br />

APPRENTICES: ENSURING ROOFING<br />

ISN’T A FINAL RESORT<br />

Total Contractor caught up with roofing contractor Jason Wright to discuss the<br />

importance of changing perceptions of the sector and to hear why he feels roofing<br />

needs to be presented to pupils earlier, so they make a conscious decision to pursue a<br />

career in the sector, rather than being pushed into it as a final resort.<br />

Alot of good work has been going on<br />

promoting the benefits of a career in<br />

roofing following National Apprenticeship<br />

Week (7th-13th Feb). And whilst those within the<br />

sector are well aware of the many opportunities a<br />

career in roofing can offer, taking the message<br />

further afield so we can attract the volume of<br />

quality new entrants to meet demand is a<br />

challenge that still remains. We caught up with<br />

contractor Jason Wright to hear why the age we<br />

speak to school children about a career in<br />

construction and changing outdated perceptions<br />

of the sector go hand-in-hand, and are key to<br />

broadening the pool of new entrants we attract,<br />

and more importantly, ensuring they have a<br />

passion for the craft.<br />

Jason Wright is a roofing man. He followed one of<br />

the more traditional routes into roofing. Back in<br />

2019 he told Total Contractor: “From the age of 8,<br />

every weekend and all school holidays I was<br />

taken to work by my father mainly to keep me out<br />

of mischief. By the age of 12 I was labouring for<br />

two roofers, and before I was 16 I had my own<br />

team.”<br />

Advocate of apprenticeships<br />

His career has flourished since then and he’s<br />

now the Managing Director of established<br />

contractor J Wright Roofing, sits on both the NFRC<br />

Heritage Committee and the NFRC Slating & Tiling<br />

committee, as well as the Craft Committee of the<br />

Worshipful Tylers & Bricklayers of London.<br />

Jason is also a strong advocate of<br />

apprenticeships having seen first-hand how they<br />

work for both the individual and the company. He<br />

told Total Contractor: “I took on my first<br />

apprentice back in 1997 because I saw the<br />

problems then of recruiting post-16 school<br />

leavers – by the time they’re 16, they’ve been<br />

pushed down the construction route for one of<br />

two reasons; they’re not academically gifted<br />

enough to go on to further education or Uni, or<br />

they’re what I call the ‘bad lads’ who’ve been<br />

given no guidance, no direction, so construction’s<br />

deemed their only route.”<br />

This, Jason says, also leads to bad experiences<br />

for the contractors recruiting apprentices and<br />

ultimately contributes to the low retention rates of<br />

apprentices who are understandably<br />

disinterested, as they’ve ultimately been forced<br />

into the sector rather than making their own<br />

choice: “What happens is you’ll get smaller to<br />

medium-sized contractors taking on these lads<br />

and they’re either too difficult to handle or the<br />

lads get disillusioned – you do get the odd rough<br />

diamond, but the dropout rate is staggering<br />

Jason Wright and members<br />

of his team discuss the<br />

opportunities in roofing<br />

with pupils.<br />

(Jason says over 70% of 16+ school-leavers<br />

that enter construction leave within 18 months)<br />

and what can you expect when they’ve been<br />

given no guidance, they’ve not made the choice,<br />

they’ve been pushed into the sector as a last<br />

option so there’s no passion for it.”<br />

Presenting to pupils earlier<br />

With this in mind, Jason feels construction – and<br />

roofing – needs to be presented to children at a<br />

younger age rather than being a final resort or<br />

afterthought. He points out there’s still a huge job<br />

to be done around changing outdated perceptions<br />

of the sector and improving the image of roofing<br />

and the wider construction industry. Jason<br />

explained: “We’ve got an image problem in<br />

construction right across the board – not just<br />

roofing. We’re still perceived by the education<br />

system and established elite as a ‘failure’; you’ve<br />

failed if you end up in construction – there’s a<br />

massive snobbery; if your son or daughter goes<br />

into construction it’s a failure. The pressure in<br />

schools is still further education, further<br />

education, further education.”<br />

I mention the construction ambassadors and<br />

those from the sector entering schools, and<br />

whilst Jason feels there is progress being made in<br />

this area – he does this himself – he feels we<br />

still need to get to children earlier and have a<br />

more sustained interaction with them. Jason<br />

explained: “We’re giving these talks too late; once<br />

they get to 16 they’ve made their choice and<br />

they’re probably thinking further education or Uni.<br />

We need to be speaking to them in Year 9.”<br />

Construction departments<br />

Jason points to a successful initiative he started<br />

in 2008 with schools in his area whereby they<br />

connect with the pupils in Year 9 and run a<br />

vocational course over the next two years<br />

covering brickwork, joinery and roofing. This,<br />

Jason points out, gives children a much wider<br />

experience of what’s really involved in a career in<br />

construction and roofing.<br />

Jason has established a construction department<br />

in one school and trained up the arts teacher to<br />

be a hands-on construction tutor. He’s also<br />

replicating this format at another school.<br />

He explained: “So over that two-year period we’d<br />

go in one day a week – all voluntarily – to assist<br />

the tutor so he has the skills to support the kids.<br />

The hardest thing we had to do was convince the<br />

Head Teacher to let this be a two-hour lesson –<br />

ideally, we wanted the whole morning or<br />

afternoon – but she wouldn’t budge. So we had to<br />

do it in a two-hour session twice a week.”<br />

He continued: “We get to know the students, get<br />

to know their characters – we get to know the<br />

ones that have got a bit about them, get to know<br />

what their personalities are like and come 16,<br />

they get the opportunity to come for an interview<br />

for a two-year apprenticeship.”<br />

Jason feels an initiative like this is what is<br />

required to increase the numbers of new entrants<br />

Jason’s initiative with a local school has produced many skilled apprentices who have a passion for the roofing sector.<br />

to the sector, but more importantly he points out industry all need to be working together, but<br />

it will improve the retention of workers as they unfortunately education is the biggest stumbling<br />

know what the sector is about, and have made a block as you have a lot of schools that get paid on<br />

conscious decision to be there: “We proved over performance and their performance is measured<br />

many years it’s a successful model – we had on how many students go on to further education<br />

over 96% success rate from taking on a pupil and Uni – they have a vested interest to keep<br />

that we worked with through Year 10 and 11. bums on seats and until we change the policy<br />

and the curriculum, and government realise<br />

“There’s lots of success stories just from our<br />

there’s going to be no one coming in to carry out<br />

business – many of our apprentices have gone on<br />

these hands on skills to meet their everincreasing<br />

targets, which is chronic now – let<br />

to start their own businesses and they’re now<br />

employing their own staff. They’ve seen it work<br />

alone the next 5 - 10 years – we’re just not going<br />

for them and they see the value in apprentices.”<br />

to get anywhere.”<br />

And this is the key for Jason: “It creates the<br />

And that’s the very real worry – until we change<br />

legacy, keeps the cycle running – what better<br />

the perception of roofing and the wider<br />

outcome could you want? It’s a complete<br />

construction industry to external stakeholders,<br />

conveyor belt of talent and if you’ve not got that<br />

we’re going to be in the same position and having<br />

conveyor belt of talent coming through, you’re just<br />

the same conversations for years to come. As<br />

going to wither and die.”<br />

Jason has proven, a huge part of shifting the<br />

balance involves speaking to children earlier,<br />

A monumental shift is required<br />

presenting what the sector’s about so if they do<br />

So, can this model be adapted and replicated<br />

decide on a career in roofing or construction, they<br />

throughout the UK? Jason feels it can, but it will<br />

do so with enthusiasm and commitment rather<br />

take a monumental shift in how schools work and<br />

than it being a last resort.<br />

a concerted effort between the construction<br />

sector, government and education system. He<br />

explained: “It’s got to be a collaboration from the Contact J Wright Roofing<br />

Preparation for Part L<br />

PART L: GET AHEAD OF THE GAME<br />

The countdown to Part L has well and truly begun, and as Sam Tebbs (pictured), Training<br />

Manager at Marley says, there’s never been a better time to assess what the changes will<br />

mean for your business, including not only what to watch out for but also how to<br />

maximise your opportunities for long-term gain...<br />

Successful outcomes are usually borne out<br />

of thorough preparation, and the roofing<br />

industry is no different. Whilst Part L will<br />

inevitably demand changes to working practises,<br />

those roofing contractors that have taken the<br />

trouble to research, prepare and adapt their<br />

businesses to embrace the changes, will find<br />

themselves ahead of the game.<br />

What Part L means for you<br />

The Part L building regulation covers the<br />

‘Conservation of Fuel and Power’ regarding both<br />

new construction projects and some refurbishment<br />

work for dwellings and other buildings in England.<br />

Put simply, it means that developers will be<br />

required to ensure that the buildings they produce<br />

meet the Government’s stringent energy targets –<br />

that new homes produce 31% less carbon<br />

emissions than at present. As such, they will be<br />

demanding both the high-quality products, such<br />

as solar photovoltaics (PV) systems, as well as<br />

the skilled workforce required to fit them, to<br />

enable these ambitious targets to be met.<br />

Crucially, with the demand for solar energy likely<br />

to drastically increase, roofing contractors who<br />

acquire the relevant product knowledge and<br />

installation skills now, will secure a real<br />

competitive advantage for themselves.<br />

Marley – there for roofers<br />

Marley prides itself in supporting the roofer with<br />

all aspects of work, from on-site health & safety<br />

and thorough installation guidance, through to<br />

business support. And, with Part L changes<br />

imminent, roofing contractors can rely on Marley<br />

to alert, guide, equip and train them with<br />

everything they need for success post June 15th<br />

when Part L is finally implemented.<br />

Train to gain<br />

Taking the lead, Marley has<br />

developed a free and<br />

comprehensive series of speciallytailored<br />

webinars to provide roofing<br />

contractors with invaluable information<br />

not only on Part L, but also the very real<br />

benefits of solar energy, focussing on Marley<br />

SolarTile, as well as the Microgeneration<br />

Certification Scheme (MCS) which covers<br />

installations of solar PV systems.<br />

The new ‘Introduction to Part L and<br />

solar roofing’ webinars aim to walk<br />

roofing contractors through six<br />

essential aspects of the new<br />

developments:<br />

• Understanding Part L<br />

• How Part L affects YOUR business<br />

• The future is solar roofing<br />

• How solar (PV) works<br />

• What MCS accreditation means for YOU<br />

• Installing Marley SolarTile<br />

There are currently three dates for the webinar:<br />

Wednesday 23rd <strong>March</strong>; Wednesday 27th April;<br />

and Wednesday 25th May, with more planned in<br />

the coming months. Available to anyone within<br />

the construction and roofing industry, simply visit<br />

www.marley.co.uk/partL for further details and<br />

to book your space.<br />

Marley SolarTile - the future is here<br />

Marley’s integrated SolarTile is compatible with<br />

all clay and concrete tiles and slates, so solar PV<br />

can easily be incorporated into any roof design.<br />

Supplied as a complete kit, all<br />

components, such as adhesive<br />

flashing and fireproofing materials<br />

are included and, featuring double<br />

fixing to battens and trusses,<br />

there’s no need for counter battens so<br />

there’s no extra material costs.<br />

Coming in colour-coded boxes for ease of<br />

installation, the patented push-together design<br />

means that installation times of less than one<br />

hour per kilowatt peak can be achieved.<br />

In addition, for roofing contractors<br />

purchasing the full Marley<br />

SolarTile system, Marley is<br />

offering invaluable on-site<br />

installation training – for the first<br />

installation – to ensure customers<br />

maximise the opportunity presented by solar<br />

energy. Upon purchase, simply contact us to<br />

organise a date for one of our team to assist with<br />

your first on-site installation.<br />

At Marley, we want our customers to be prepared<br />

for the far-reaching effects of Part L. Of course,<br />

with change there are potential threats to a<br />

roofing contractor’s business, however, there are<br />

also great opportunities provided they take full<br />

advantage of the wide range of resources and<br />

innovative new products that are out there to help<br />

Perfectly Pitched<br />

REPLACING INDIVIDUAL<br />

TILES AND SLATES<br />

Technical Roofing Consultant John Mercer continues his focus on best practice when<br />

working on pitched roofs, this month providing key advice for roofers on how to<br />

mechanically fix individual replacement tiles.<br />

Ever since BS 5534: the British Standard<br />

Code of practice for slating and tiling was<br />

revised in 2014 to require that all single<br />

lap tiles be mechanically fixed on a roof, a topic<br />

that often crops up is how to mechanically fix<br />

individual replacement tiles.<br />

Prior to this change, it was common for some<br />

tiles on a roof not to be secured other than by<br />

being hung on the tile batten and, to some extent,<br />

relying only on their own weight and the<br />

surrounding tiles to remain on the roof. It was<br />

common practice for roofers to leave a few tiles<br />

unfixed and slide them up to leave the batten<br />

underneath exposed as a foot hold<br />

whilst working on other parts of<br />

the roof.<br />

Left: John Mercer, Technical Roofing Consultant. Above: Illustration showing tail clip placement.<br />

Single lapped tiles<br />

How a replacement tile is<br />

mechanically fixed depends to<br />

some extent on the original<br />

calculated fixing specification for the<br />

roof. The replacement tile’s fixings must be<br />

at least as strong as the surrounding tiles’ fixings.<br />

One option is to strip the tiling back from where<br />

the damaged tile is to the nearest ridge or other<br />

roof junction. This allows all the tiles, including<br />

the one being replaced, to be fixed in accordance<br />

with the calculated fixing specification. However,<br />

depending upon the location of the problem, this<br />

could potentially involve a considerable number<br />

of tiles being removed and replaced.<br />

To replace a damaged single lap tile without<br />

removing the neighbouring tiles, firstly insert a<br />

wedge – usually a piece of tile batten will suffice<br />

– under the tail of the tile to<br />

the immediate left of the tile<br />

being replaced. The type of<br />

fixings will determine how far it is<br />

possible to open the headlap; for example,<br />

tail clips will severely limit the lifting of a tile<br />

without damaging the clip or the tile. If it is<br />

possible to lift the tile, this will also lift the tiles<br />

immediately above the damaged tile, making its<br />

removal easier.<br />

The damaged tile and its fixings must be<br />

removed. A slater’s ripper tool can normally be<br />

used to remove the original head nails and then<br />

the broken pieces of tile can be taken out. If the<br />

tail of the tile is clipped, the piece of tile held by<br />

the clip can be rotated clear of the clip. The clip<br />

will then need to be removed or rotated clear<br />

before a new tile is inserted. Keeping the wedge<br />

“The type of fixings will<br />

determine how far it is<br />

possible to open the<br />

headlap – tail clips will<br />

severely limit the<br />

lifting of a tile”<br />

that is holding open the headlap in place, the<br />

replacement tile can then be inserted.<br />

Where the replacement tile needs to be twice<br />

fixed, a suitable roofing adhesive can be applied<br />

to the side interlock of the replacement tile to<br />

secure it in place, taking care not to block water<br />

channels which may otherwise cause a leak.<br />

Once the new tile is in position, the supporting<br />

batten wedge can be removed to allow the<br />

adjacent tile to be pressed into the adhesive. For<br />

the main mechanical fix, a hole can be drilled<br />

through the tail of the replacement tile, passing<br />

through the head of the tile below and directly<br />

above the tile batten. The tile can then be<br />

secured to the batten using a stainless-steel<br />

screw with a sealing washer.<br />

To avoid having to drill the tiles, an alternative<br />

option is to secure the tile using a specially<br />

made tail clip; there are several suitable types<br />

available from tile manufacturers. These secure<br />

the tail of the replacement tile in a similar way<br />

that a slate hook secures a slate, and are held in<br />

place by the head nail or screw of the tile below<br />

(see illustration left).<br />

Natural slates<br />

Many people will be familiar with the use of<br />

hooks to secure replacement slates. Firstly, the<br />

remains of the broken slate and its nails are<br />

removed using a slater’s ripper. Then, depending<br />

“Remember to treat any<br />

tiled or slated roof as<br />

fragile and use<br />

crawling boards<br />

and/or ladders,<br />

properly supported and<br />

anchored to prevent<br />

slipping”<br />

upon the type of hook to be used, the hook is<br />

either driven into or hooked around the slate<br />

batten. The replacement slate can then be inserted<br />

and secured by the hook at its tail end. The hook<br />

should grip the slate tightly enough to prevent wind<br />

rattle and lateral movement, but should not be so<br />

tight that it would damage the slate.<br />

Plain tiles<br />

Replacing double lapped plain tiles can be<br />

relatively straightforward on average domestic<br />

roofs because rarely are they all nailed anyway.<br />

Most nailing specifications range from the<br />

minimum – nailing every fifth course, up to<br />

nailing every second or third course in more<br />

exposed areas. Where every tile must be twice<br />

nailed, for example on vertical plain tiling, it may<br />

be necessary to strip back the tiling to a<br />

convenient junction such as the ridge or top<br />

abutment and then re-nail all the tiles.<br />

Finally, remember to treat any tiled or slated roof<br />

as fragile and use crawling boards and/or<br />

ladders, properly supported and anchored to<br />

prevent slipping. Use packing between the boards<br />

or ladders and the roof to avoid damaging the<br />

surrounding tiles or slates. When carrying out any<br />

roofing work, always ensure compliance with the<br />

relevant health and safety legislation.<br />

Roofing Battens<br />

A CRITICAL ELEMENT OF ROOFING<br />

Roofers understand the risks of roofing work, especially when, according to the HSE,<br />

50% of fatal injuries result from falls from a height. But how can product choice help<br />

with safety and working at height? Two industry experts weigh in on the importance of<br />

graded battens and the role they play in site safety, as we speak to SR Timber and<br />

Bloor Homes to find out more.<br />

It starts with selecting the right<br />

product for the job, and according<br />

to the Health and Safety<br />

Executive document HSG33, that’s a<br />

graded BS5534 batten. But how are<br />

roofers to know if the batten they’re<br />

using is safe and graded? SR Timber<br />

Trading Director Shaun Revill<br />

understands the difficulty: “Those of<br />

us who have spent decades learning<br />

the craft can spot a graded batten<br />

but those less experienced have to<br />

rely on product markings to make it<br />

easier,” explains Shaun.<br />

Graded battens must be dimensionally accurate<br />

within tight tolerances on size and have the<br />

BS 5534 stamp. The SR Timber signature gold<br />

battens have always been manufactured to exact<br />

standards and with this comes more reassurance<br />

for roofers. “When you’re working at that height,<br />

you’ve got to trust the materials you’re working<br />

with. All our battens are full sized to the standard<br />

plus knot sizes, correct growth rings and slope of<br />

grain all conform to the British Standard, so<br />

there’s no doubt it’s a safe product” notes<br />

Shaun.<br />

But what does this mean for safety and roofers,<br />

especially when there’s cheaper unmarked batten<br />

products available? “It matters because of how<br />

critical battens are in roof construction. With<br />

exacting tolerances, battens need to be strong<br />

enough to support the weight of roofers, tiles, and<br />

hold fixing nails securely enough to cope with<br />

strong winds,” continues Shaun.<br />

“If the only thing keeping you on the roof is a<br />

“A substandard batten<br />

could end up being<br />

very costly”<br />

batten, you want that peace of mind which comes<br />

from it being graded. A substandard batten could<br />

end up being very costly,” Shaun warns.<br />

What about housebuilders?<br />

This feeling is echoed throughout the sector too.<br />

As one of the biggest house builders in the UK,<br />

Bloor Homes take roofers’ health and safety very<br />

seriously. Over the past decade they’ve created a<br />

list of specified products which are used in their<br />

developments. These products all meet strict<br />

standards for safety, reliability, and support.<br />

Everything relating to which roof tiles and battens<br />

to use are defined at a group level, ensuring high<br />

standards across developments.<br />

Chris Burton, Group Commercial Director for Bloor<br />

Homes, spoke on the importance this<br />

specification brings: “Using gold or red graded<br />

battens is an absolute mandate, with<br />

that comes the peace of mind that<br />

the product is safe, fit for purpose,<br />

and the guarantees we need to meet<br />

strict safety standards.”<br />

Graded battens become increasingly<br />

important when meeting quality<br />

control criteria, particularly in the case<br />

of the NHBC. “Bloor Homes has<br />

always been good in achieving the<br />

standards set by the NHBC. It’s<br />

important we comply with these to<br />

provide peace of mind to our<br />

customers, and this is only achieved by using the<br />

graded product,” explains Chris.<br />

Safety at heart<br />

It’s not just house builders whose minds are at<br />

ease with graded product. Contractors and<br />

roofers benefit from the cover and reliability<br />

afforded by the product. “Contractors know that if<br />

its gold, then that batten has met the quality and<br />

safety commitments made by SR Timber. We offer<br />

full liability and support for our product, that’s<br />

how much we trust it” Shaun says.<br />

Shaun points out SR Timber place safety at the<br />

heart of their manufacturing and purchasing<br />

process, “if a house builder or roofing contractor<br />

wants to be recognised for committing to safety,<br />

then SR Timber products only add to that<br />

reputation.”<br />

and established roofers are up to speed with the latest innovations and best practice<br />

roofing techniques...<br />

Above: Paul Lambert of Hambleside Danelaw presents to students. Paul delivers CPDs, product demonstrations, Q&As and more to roofing colleges and trade counters throughout the UK.<br />

Hambleside Danelaw are aware of the<br />

growing pressures caused by the skills<br />

shortage in the roofing industry and want to<br />

do all we can to relieve this pressure. That’s why<br />

roofing education is one of our main areas of focus.<br />

Our field tech support, Paul Lambert, had an<br />

extremely busy 2021! Travelling to colleges and<br />

training academies throughout the UK, Paul has<br />

delivered CPDs, product demonstrations, Q&As<br />

and more, furthering Hambleside Danelaw’s<br />

commitment to roofing education.<br />

Our team of Paul, Mike Lemmon and Ann Leeson<br />

supported DMG Roofing Training Academy’s grand<br />

opening in December ‘21, with Paul presenting to<br />

some of the new learners.<br />

Paul and Ann, as representatives of Hambleside<br />

Danelaw, were also invited by Stewart Rowles to<br />

watch a slating and tiling course and to see the<br />

facilities at the Master Roofers Academy in<br />

Salford. Hambleside Danelaw were also sponsors<br />

of the Great British Slate Off, run by NFRC, which<br />

showcases our commitment to educating the next<br />

generation.<br />

2021 was also a big year for our dry fix verge<br />

system offering following the launch of<br />

“This year, Hambleside<br />

continuing to support<br />

the education and<br />

growth of roofers”<br />

MidVerg20, as well as 2021 being the first full<br />

year that InVerg was available.<br />

Paul was able to provide face-to-face support in<br />

relation to these innovations (COVID-19<br />

permitting!), allowing the roofers to understand<br />

these latest products in more detail and enabling<br />

them to install the systems correctly. Paul was<br />

also able to assist in increasing general<br />

awareness of Hambleside Danelaw’s<br />

comprehensive roofing ancillaries offering. 2021<br />

saw Paul at Leeds College of Building, South<br />

Lanarkshire College, and CoRe Training Centre to<br />

name just a few.<br />

This year, we’re continuing to support the<br />

education and growth of roofers, from apprentices<br />

to masters, in a number of ways including:<br />

• By becoming Tier 1 Sponsors of Master Roofers<br />

• Dedicating resources and time to the<br />

production of a free learning platform (see the<br />

Hambleside Danelaw Hub)<br />

• And continuing to contribute to the high<br />

standards of the roofing industry.<br />

From Dundee to Newcastle, Fife to South Devon,<br />

45+ YEARS OF ROOFING INNOVATION


BS 5250<br />

TACKLING THE CHALLENGES OF<br />

ROOF SPACE VENTILATION<br />

Paul Manning, Managing Director at Manthorpe Building Products, looks at the<br />

challenges around roof space ventilation for roofing contractors, and gives an overview of<br />

the solutions Manthorpe offers to help roofers meet the latest requirements of BS 5250.<br />

Manthorpe Building Products is a<br />

company that specialises in and<br />

understands the topic of ventilation<br />

particularly well. At Manthorpe, we’ve been<br />

developing innovative building products for the<br />

construction industry for over 30 years and have<br />

extensive experience in the use of plastics, as<br />

well as the expertise to develop and manufacture<br />

virtually all our products in-house. Alongside this,<br />

we continue to invest heavily in new technology<br />

and production processes.<br />

All Manthorpe products are<br />

independently tested when<br />

required via independent<br />

testing organisations, such as<br />

Building Research<br />

Establishment (BRE) and<br />

Warringtonfire, to meet British<br />

Standards and to achieve<br />

relevant accreditations. We pride<br />

ourselves on having close relationships<br />

with independent and national merchants, thus<br />

ensuring that our products are available from a<br />

wide range of outlets throughout the UK.<br />

Revisions to BS 5250<br />

In 2021, BSI Standards published a major<br />

revision to BS 5250: Code of practice for<br />

Management of moisture in buildings. So, it is an<br />

opportune time to revisit the topic of ventilation.<br />

Although the general approach to roof space<br />

ventilation and control of condensation has not<br />

changed markedly in this latest revision, it does<br />

contain new guidance on moisture risks other<br />

than condensation, a whole building approach to<br />

moisture-safe design, building context, the<br />

Images: Manthorpe offers a range of ventilation solutions including its Interlocking Plain Tile Vent.<br />

coherence of design and<br />

detailing interactions, as<br />

well as capacity and inservice<br />

conditions. It also<br />

covers the management of moisture<br />

risks in buildings undergoing energy saving<br />

measures.<br />

The revision acknowledges key changes in<br />

modern building design, such as reduced air<br />

permeability of the building fabric and higher<br />

thermal insulation, both of which have the<br />

potential to increase the risk of condensation. It<br />

also considers changes in lifestyle and the<br />

greater use of moisture-generating appliances<br />

such as showers and internal clothes drying.<br />

Climate change is also predicted to add to the<br />

moisture risk through milder, more humid winters<br />

and more frequent and heavier incidents of<br />

driving rain events.<br />

The differences between ‘as designed’, ‘as built’<br />

and ‘in service’ conditions are now more clearly<br />

understood, as is the way occupants use the<br />

building, which may not always be in the manner<br />

intended, as well as the residual moisture held in<br />

the building fabric from the construction<br />

processes. This all means that the moisture risk<br />

evolves and changes over time and during the<br />

lifetime of the building, and designers are<br />

encouraged to allow for the worst-case scenario.<br />

As well providing guidance developed through<br />

modelling, BS 5250 gives prescriptive guidance<br />

based on the evidence of many years of<br />

successful use. This particularly applies to roof<br />

construction, where there is plenty of data and<br />

evidence to provide practical recommendations<br />

for the use of ventilation to prevent moisture risk.<br />

Whilst continuous eaves and dry ridge systems<br />

can generally be relied upon to provide the<br />

required ventilation into loft spaces for<br />

straightforward gabled roofs, sometimes the roof<br />

design means that extra ventilation is necessary.<br />

For example, where ridge, or high-level ventilation<br />

is required, but the ridge length is very short on a<br />

hipped roof, tile ventilators positioned in the hip<br />

end roof slopes are an ideal way to supplement<br />

the high-level ventilation of the roof space.<br />

Products to ensure compliance<br />

At Manthorpe we’re one of the UK’s leading<br />

experts on roof space ventilation and we offer<br />

some unique and innovative products to ensure<br />

compliance with BS 5250 and maintain a<br />

condensation-free roof structure.<br />

For example, the<br />

Cowled Universal Roof<br />

Vent (pictured right), or CURV<br />

for short, is possibly the only truly<br />

universal tile ventilator on the market. It can be<br />

used with a wide variety of single lapped roof tiles<br />

and slates, making it especially useful where the<br />

installer may not know what the roof covering is.<br />

It can be used with large and small format<br />

interlocking tiles, both flat and profiled in design,<br />

including deep bold roll styles of tile and, with a<br />

minimum roof pitch of just 12.5 degrees, it is one<br />

of the lowest pitch ventilators on the market,<br />

making it ideal for lean-to house extensions. The<br />

vent is fitted with a versatile flashing skirt which<br />

can be dressed to match the relevant profile of<br />

the roof covering and comes with an adhesive<br />

mastic backing which securely seals the flashing<br />

down to the roof. The hooded cowl protects the<br />

opening from the elements whilst providing an<br />

airflow path into the roofspace. An integral 4mm<br />

louvred grill within the cowl prevents the entry of<br />

debris and large nesting insects. For mechanical<br />

extraction or soil stack / vent pipe termination,<br />

the lower outlet is stepped to allow for 4", 5" or<br />

an oval 6" connection. The CURV has been fully<br />

independently wind-driven rain<br />

tested and is the perfect<br />

single-stock vent for merchants<br />

and roofers alike.<br />

Another innovative product in the<br />

Manthorpe range is<br />

the interlocking plain tile<br />

ventilator (above top and<br />

previous page), designed<br />

specifically for use with small format twin, or duo<br />

plain tiles. This product incorporates a unique<br />

patented design feature, a sliding mechanism, to<br />

adjust its width to suit the different sizes of tiles<br />

available. This means that it is the only vent<br />

which suits all the versions of concrete<br />

interlocking plain tiles currently on the market.<br />

This makes it ideal for merchants and contractors<br />

who only need to stock one interlocking plain tile<br />

vent product.<br />

The curved, in-line profile of the Manthorpe plain<br />

tile ventilator helps to maintain an unbroken<br />

appearance to the roofline at high or low level with<br />

a range of colours available to suit varying roof<br />

styles. The vent is suitable for roof pitches down to<br />

22.5 degrees and is fully wind-driven rain tested.<br />

The intricate path through the internal weathering<br />

geometry is designed to maintain a constant<br />

airflow gap of 6,000mm² whilst safely channelling<br />

any water out of the vent and on to the roof<br />

covering below. The 4mm louvred grill prevents the<br />

entry of debris and large nesting insects.<br />

extraction or soil stack / vent<br />

Both these innovative ventilators can be easily<br />

LEARNING AND UPSKILLING TO<br />

CREATE THE ROOFS OF THE FUTURE<br />

Paul Campbell, Marketing and Technical Director at BMI, discusses how the role of<br />

continuous learning and upskilling is the key to solving the skills shortage and creating<br />

the roofs of the future.<br />

The construction industry is in a period of<br />

great change and transformation, the<br />

housing shortage requires innovation and<br />

radical thinking, the challenges of urbanisation<br />

and expanding cities mean we need to improve<br />

our facilities and infrastructure, all whilst<br />

protecting the environment for future generations.<br />

As an industry, we have not done enough to show<br />

how rewarding and diverse a career in<br />

construction can be, and we have skills shortages<br />

as a result. Future skills are the critical success<br />

factor in designing and building our future<br />

environments.<br />

These changes in demand inspire innovation of<br />

materials, technologies and construction<br />

methods. The drive for sustainable solutions, the<br />

adoption of modular construction and the<br />

digitisation of data and design are great examples<br />

of how our industry is evolving.<br />

The overarching themes here are ensuring built<br />

performance meets every aspect of the<br />

specification, delivering lasting quality and<br />

establishing more efficient ways of working. The<br />

roofing industry plays a vital part within the wider<br />

construction sector to lead this transformation.<br />

Yet, transformations are people-led, making<br />

continuous learning and upskilling a crucial<br />

requirement for the roofer of tomorrow.<br />

So, what can the roofing industry do to stay<br />

ahead of the game?<br />

Product development and innovation<br />

inform the learning curve<br />

To future-proof roofing, the industry is constantly<br />

finding ways to do things better, from the<br />

introduction of new regulations, such as<br />

BROOF(t4), the highest European fire<br />

rating to increase safety in flat<br />

roofs, to ensuring that new<br />

homes and buildings reduce<br />

their carbon footprint with the<br />

implementation of the upcoming<br />

changes to Part L of the Building<br />

Regulations on 15th June <strong>2022</strong>.<br />

With these changes in mind, roofing<br />

manufacturers are first in line to respond to the<br />

challenges by looking at ways to ensure that their<br />

products and systems meet these changing<br />

needs and regulations. As the UK’s largest roofing<br />

manufacturer, at BMI we’re known for our leading<br />

flat roofing brand BMI Icopal and, in pitched<br />

roofing, BMI Redland, and we’re constantly<br />

striving to ensure product safety and future-led<br />

problem solving. From championing safe working<br />

practices by means of solvent-free installation<br />

with products like our liquid-applied<br />

waterproofing system Sealoflex, to new integrated<br />

solar PV solutions with BMI Redland’s PV InDaX<br />

Adapt in-roof photovoltaic system, roofers can<br />

find solutions to almost any challenge they face.<br />

The development of new products and systems<br />

naturally have a positive impact not only on the<br />

built environment, but on the environment at<br />

large. Innovative roofing can eliminate issues<br />

with storm water management and drainage,<br />

while new advances in bitumen membranes like<br />

BMI Icopal’s Groove Technology helps minimise<br />

energy usage during installation.<br />

And while it is crucial to reduce carbon emissions<br />

and minimise the risk of water and energy waste,<br />

it has become increasingly evident that as an<br />

industry, we simply must do more to close the<br />

Director at BMI.<br />

gap between design and as-built<br />

performance. As we know, the<br />

government is “looking to<br />

industry to lead culture change on<br />

the ground”. In Building a safer<br />

future, Dame Judith Hackitt’s report, she<br />

recommends the introduction of a ‘golden thread’<br />

to support duty holders in designing, constructing<br />

and managing their buildings as holistic systems,<br />

taking into account building safety at all stages in<br />

the life cycle. This independent report calls for a<br />

reform of building safety and leads us to focus on<br />

ensuring that what we design will be safe,<br />

efficient and long-lasting in its as-built<br />

performance. For roofs to meet these criteria and<br />

align with new building regulations, innovation<br />

across materials, processes and roofing skills is<br />

vital.<br />

However, critical to all innovation is systems<br />

thinking and testing and validation. At BMI we’ve<br />

invested significantly in internal testing capability<br />

and we partner with leading test houses to ensure<br />

that all solutions are thoroughly tested and<br />

designed for future needs in all building types.<br />

Full system thinking ensures that all products and<br />

components are designed to fit together<br />

seamlessly.<br />

Learning away from the rooftop<br />

Naturally, product development and innovation<br />

require continued learning and upskilling, not just<br />

by roofers, but by everyone who works with and<br />

around roofing. And with the industry continuing<br />

to change at such a rapid pace, anyone with a<br />

stake in roofing will want to stay ahead – and<br />

learning by simply doing might not always be<br />

enough.<br />

Ongoing, regular training on new products,<br />

improved methods of installation, new tools and<br />

systems can close the gap and ensure that<br />

everyone, from experienced contractors right<br />

through to apprentices, is equipped with the right<br />

skills to secure the future of UK roofing.<br />

Recognising the vital importance of providing<br />

support and continued learning opportunities, BMI<br />

offers many different ways to access in-depth<br />

training and skills development from project<br />

specification to planning and build, to help make<br />

sure that new products are specified and<br />

installed right first time.<br />

The BMI Academy offers continued learning and<br />

upskilling opportunities to everyone in the roofing<br />

and waterproofing industry. Through both<br />

theoretical and practical courses, BMI Academy<br />

helps to drive excellence in roofing, providing best<br />

practice support on how to use new and existing<br />

products and solutions prior to installation. Not<br />

just for roofers, these learning and training<br />

opportunities are also available to specifiers,<br />

architects, contractors, builders, and merchants,<br />

ensuring best practice right from the start.<br />

Providing solid foundations for the<br />

future of roofing<br />

Every roof needs a strong and<br />

sturdy foundation that can<br />

weather changing times and,<br />

like the roof itself, the future of<br />

roofing is built on the talent we<br />

develop and support from the<br />

ground up.<br />

Every year, BMI holds the Apprentice of the Year<br />

competition, inviting roofing apprentices to<br />

submit their entries to be part of a lively and<br />

challenging competition to demonstrate their<br />

roofing skills, business acumen and leadership<br />

qualities.<br />

Bringing together industry associations,<br />

“The future of<br />

roofing must be<br />

secured from<br />

the ground up”<br />

contractors, apprentices, and<br />

colleges, the competition is just one<br />

example of how BMI seeks to inspire the future<br />

generation of roofers by showing how diverse and<br />

rewarding it can be. Julian Coulter, Company<br />

Director at Sussex Asphalt and Chairman of<br />

Mastic Asphalt Council in the UK, noted that the<br />

competition bolsters the image of the industry,<br />

highlighting the importance of apprenticeships for<br />

the wider sector. Quoting Henry Ford, Julian says<br />

that “The only thing worse than training your<br />

employees and having them leave, is not training<br />

them, and having them stay”, highlighting the<br />

crucial importance of providing roofing<br />

apprentices and young roofers with continuous<br />

training and learning opportunities to develop<br />

their skills.<br />

Speaking of the event, Ruth Scarrott, Head of<br />

Careers at NFRC, says “Without doing these types<br />

of events, which are really exciting opportunities<br />

for young people to show their skill set, we will<br />

just lose that interaction and interest, so why<br />

wouldn’t we provide that opportunity for young<br />

people to show us what they can do?”<br />

To further our commitment to ongoing<br />

training and support, during this<br />

year’s National Apprenticeship<br />

Week, BMI Academy visited<br />

colleges across the UK to deliver<br />

tailored training sessions and offer<br />

advice and practical product<br />

demonstrations to roofing apprentices and<br />

college tutors. Lecturer and Assessor Luke<br />

O’Gorman from Bolton College said BMI’s visit<br />

was a “fantastic incentive, and really useful for<br />

our first-year roof slating and tiling group to hear<br />

directly from a manufacturer about product<br />

installation and the importance of doing it<br />

correctly.” Harry Teasdale, Head of Construction<br />

at Newcastle College, echoed this sentiment<br />

Left: Jamie Scott, of Bourne-based Sandall<br />

Roofing, was BMI’s Pitched Roofing<br />

Apprentice of the Year 2021<br />

about BMI’s visit to Newcastle<br />

College, noting that “the<br />

resources you provide make a<br />

huge difference to our apprentices,<br />

very much appreciated.”<br />

Securing the future of roofing through<br />

continuous support<br />

The future of roofing must be secured from the<br />

ground up by ensuring close collaboration between<br />

roofing manufacturers and all stakeholders across<br />

the industry, from apprentice roofers right through<br />

to housebuilders, contractors, merchants,<br />

specifiers and those developing regulations and<br />

guidance for the industry.<br />

Providing ongoing support not just through<br />

innovative product development that makes the<br />

day-to-day life of installers and homeowners<br />

easier and safer, but through continued learning<br />

and skills development, the roofing industry will<br />

continue to be built on a solid foundation of<br />

knowledge and expertise. BMI’s flat roofing brand<br />

Icopal and pitched roofing brand Redland are<br />

paving the way for more energy-efficient, safe,<br />

and long-lasting roofing systems, but it will<br />

ultimately be the people designing, planning,<br />

installing and maintaining them that will make<br />

the difference.<br />

This is why BMI’s commitment to continuous<br />

learning and skills development starts from<br />

within, by ensuring that the technical teams at<br />

BMI are best equipped to innovate and adapt<br />

roofing products and advise customers on how<br />

best to meet new requirements. This expertise<br />

forms the foundation for the cultivation of future<br />

talent. The steps we take today to support and<br />

develop roofing talent at all levels will shape the<br />

construction industry of tomorrow.<br />

Vapour Control Layers<br />

THE UNSUNG HEROES<br />

OF ROOF LONGEVITY<br />

Nestled between the roof deck and insulation sits a crucial component to ensuring the<br />

longevity roofs – the vapour control layer (VCL). Sunny Lotay (pictured), National<br />

Commercial Manager at PermaRoof Commercial, part of PermaGroup, says when<br />

properly installed in conjunction with the correct venting and membranes, a VCL can<br />

all but eradicate the risk of condensation forming and damaging the structural integrity<br />

of a roof. Below, he discusses how overlooking this element at specification can result<br />

in damage to a brand-new roof, and even its premature failure.<br />

It’s a well-known fact that the UK has a<br />

condensation problem due to a combination of<br />

factors, not least the infamous British<br />

weather, which, if left unchecked, can have<br />

disastrous consequences for building structures.<br />

However, an arguably lesser known fact is that,<br />

when it comes to roofs, there’s a two millimetre<br />

thick solution that can guarantee it doesn’t fall at<br />

the first hurdle.<br />

Vapour control layers (VCL) are a<br />

critical building component that<br />

protect a building from<br />

degradation by managing the<br />

passage of water vapour within<br />

its structure.<br />

Changing regulations<br />

Historically, the UK has always opted for cold flat<br />

roof solutions, where the insulation sits between<br />

“We recently conducted a core test on a<br />

property where a roof had been refurbished one<br />

year previously but, due to the absence of a<br />

vapour control layer, the roof was already<br />

beginning to fail”<br />

the roof deck and above the<br />

plasterboard. However, this<br />

application is now banned in<br />

Scotland, with England set to<br />

follow suit due to refreshed<br />

building compliance regulations.<br />

Therefore, any refurbishments or new<br />

specifications have to be upgraded to warm<br />

roofs, where the insulation is applied on top of<br />

the existing roof surface, as this greatly reduces<br />

the risk of condensation build up and resulting<br />

damage.<br />

Within the new regulations the VCL is fixed to the<br />

roof deck before the insulation is applied.<br />

Depending on the type of system and needs of the<br />

Vapour Control Layers<br />

Continued from page 36<br />

PermaRoof Commercial says vapour control layers (VCLs) are a critical building component which must not be overlooked.<br />

project, this can either be mechanically attached<br />

or self-adhesive used. Conducting a roof survey<br />

is vital as it identifies what the substrate of the<br />

roof is and, as a result, the type of vapour control<br />

layer that needs to be specified.<br />

Preparation is key<br />

Despite the huge difference a VCL can make, we<br />

regularly see instances where people haven’t had<br />

one installed, meaning that there’s insulation<br />

attached directly onto the substrate with no<br />

moisture control in place. While this may not<br />

present an immediate issue, there is unseen<br />

damage being done from day one as it speeds up<br />

the rotting process. For example, we recently<br />

conducted a core test on a property where a roof<br />

had been refurbished one year previously but, due<br />

to the absence of a vapour control layer, the roof<br />

was already beginning to fail.<br />

It’s cases such as these that showcase the<br />

importance of the correct specification and<br />

building plans, which enable the creation of a full<br />

system that stands the test of time.<br />

Compromising on quality<br />

At a time when anyone can pick up the tools and<br />

materials they need from a building products<br />

provider, cost will always be a crucial factor when<br />

looking at a roofing project, meaning they will go<br />

with the cheapest quotes or attempt the<br />

installation themselves.<br />

However, this doesn’t necessarily mean they’re<br />

getting the full system and best solution.<br />

As the upfront cost of a VCL is relatively low in<br />

comparison to the overall budget of a roof<br />

installation, it can often be misinterpreted as a<br />

‘nice to have’ rather than a ‘must have’, and this<br />

is something that needs rectifying. Without a<br />

vapour control layer you risk black mould, heat<br />

loss, surface condensation, internal condensation<br />

and, ultimately, structural failure that will cost<br />

even more than the initial application of the VCL<br />

layer itself.<br />

Talk to the experts<br />

The recent DIY boom has been fantastic for the<br />

building products market, however, when it<br />

comes to roofs, I would always urge people to<br />

speak to a specialist to ensure the right solution.<br />

There are so many variables and unique factors<br />

lying within a roof that can be overlooked, VCLs<br />

being the prime example, which can mean the<br />

difference between longevity and premature<br />

failure and, without that base knowledge, it’s<br />

highly likely that incorrect specifications could<br />

continue for years to come.<br />

Tapered Roofs<br />

DESIGNING OUT FLAT ROOF FAILURE<br />

Iain Macpherson, Head of Business Unit – Refurbishment at TaperedPlus, talks flat<br />

roof failures and explains how the company can assist contractors in eliminating<br />

ponding by designing an adequate fall into the roof with the use of tapered insulation.<br />

With a changing landscape regarding the<br />

use of insulation products in the<br />

construction industry, it makes sense to<br />

work with impartial experts when looking for<br />

advice and guidance.<br />

Formed in 2014, TaperedPlus work with many<br />

manufacturers of waterproofing systems and<br />

insulation to ensure that the appropriate<br />

materials are used on a variety of roofing and<br />

external cladding projects. Chief Technical Officer,<br />

Rob Vass, plays an active part in technical<br />

committees across the roofing industry, advising<br />

on interpretation of existing legislation and where<br />

improvements could be made in relation to<br />

performance and safety.<br />

In recent times, the use of the correct insulant in<br />

the construction or refurbishment of a building<br />

has been seen as a key factor in ensuring the<br />

safety of the occupants of the building in<br />

question. Therefore, it is of the utmost importance<br />

that you ensure you are offering the correct product<br />

for any application. In the world of contracting it is<br />

almost impossible to keep up to speed with<br />

technical innovations in so many product groups. So<br />

having an expert on call who can provide technical<br />

support and advice in an area of construction under<br />

scrutiny at present is invaluable.<br />

Selection of the most effective materials is key to<br />

achieving the necessary thermal performance on<br />

any project and with a number of alternatives<br />

available in the market from VIP panels to EPS,<br />

glass to mineral wool, Polyisocyanurate to<br />

Phenolic, to the untrained eye this can be a<br />

daunting process.<br />

Our specific area of expertise lies within the flat<br />

roofing element of construction, an ever popular<br />

choice for designers due to speed of construction<br />

and cost saving when compared against some<br />

“Many flat roof<br />

failures can be<br />

traced to the<br />

inability of the<br />

roof to shed<br />

rainwater from its<br />

surface” Iain Macpherson<br />

pitched roof alternatives.<br />

Many flat roof failures can be traced to the<br />

inability of the roof to shed rainwater from its<br />

surface, leading to the formation of water ponds.<br />

Ponding of rainwater can decrease the design life<br />

of a roof by subjecting its waterproofing<br />

membrane to attack from thermal stress and<br />

growth of plants, moss and algae. Ponding water<br />

can also create a number of issues away from<br />

membrane failure such as blocked outlets from<br />

debris, increased maintenance requirements, slip<br />

hazards to those maintaining the roof, poor<br />

aesthetic appearance, progressive deflection of<br />

the roof deck, as well as stagnant water odor and<br />

the associated hygiene issues.<br />

Due to the problems outlined above, the relevant<br />

British Standards, Guidance Documents and<br />

Building Warranty Provider Standards all have<br />

minimum standards in relation to falls on roofs.<br />

In most circumstances, a lack of falls can result<br />

in invalidating a membrane manufacturer’s third<br />

party accreditation and may jeopardize a<br />

project’s system warranty.<br />

The most effective solution is to eliminate<br />

ponding by designing an adequate fall into the<br />

roof with the use of tapered insulation.<br />

The cornerstone of the TaperedPlus service offer<br />

is tapered roofing schemes, and as we are<br />

independent of any particular<br />

manufacturer of insulation products,<br />

this means that we have the<br />

flexibility to offer a variety of<br />

solutions on a project dependent<br />

upon thermal performance and<br />

budget. Our newly formed Refurbishment<br />

Business Unit team has over 120 years of<br />

experience of working in the roofing industry, and<br />

understand the issues faced by contractors when<br />

trying to meet deadlines and beat the vagaries of<br />

the British weather.<br />

It is always our preference to meet the contractor<br />

and waterproofing manufacturer on site to ensure<br />

we understand the brief clearly before submitting<br />

proposals, and under normal circumstances it is<br />

anticipated that a bespoke design will be issued<br />

within 48 hours of carrying out a site survey of a<br />

project.<br />

Once the design has been approved, we work<br />

with the customer to ensure scheduled deliveries<br />

are arranged, on appropriate forms of transport,<br />

within the project timeframes. If required we can<br />

attend pre start meetings to ensure all parties<br />

understand how the design works and the<br />

methodology that should be employed in order to<br />

deliver a finish in line with our proposals.<br />

So if you have a need for the expertise of the UK’s<br />

fastest growing independent provider of tapered<br />

roofing schemes, then look no further than<br />

TaperedPlus, a national leader in providing quality<br />

flat roof design.<br />

Slate Tiles<br />

FROM A ROCKY START TO DECADES<br />

OF SUCCESS IN THE SLATE SECTOR<br />

Ahmed El-Helw, founder and Managing Director of natural slate specialists SSQ,<br />

reflects on his time in the slate sector which started with a tough lesson learned the<br />

hard way, but developed into a successful, thirty-year partnership built on trust with<br />

the Del Carmen Quarry…<br />

My career in slate got off to a rocky start.<br />

It was in 1980 that I found myself at a<br />

trade show in Spain, and came across a<br />

display of Spanish slate for the first time.<br />

It was a fateful encounter, because it started me<br />

down a path that would end with me founding one<br />

of the UK’s leading natural slate suppliers.<br />

But in the early days of SSQ, I was young, and<br />

had a lot to learn. The slate I managed to source<br />

was of poor quality, and I had to pay out large<br />

sums in guarantees when it began to<br />

fail on my customers’ roofs.<br />

The claims were substantial<br />

– more than the value of the<br />

company. At the time, my<br />

lawyer and accountant both<br />

advised me to close, but I<br />

refused.<br />

I was determined to persevere and did the<br />

honourable thing – replaced every roof I needed<br />

to, showed the sector I was a man of my word<br />

and maintained SSQ’s integrity.<br />

What did I learn from the experience? That slate<br />

is a natural material. It’s not made in a factory.<br />

No two pieces of slate will ever be exactly the<br />

same.<br />

Different countries, different regions, different<br />

quarries, even different veins of rock will all<br />

produce a different quality of slate – so really,<br />

who selects the slate you buy is just as important<br />

as the country it comes from.<br />

In short, I learned that if I wanted the most<br />

Above: The Del Carmen Quarry, Spain. Left: Manuel Maestre Vega, Founder of the Del Carmen Quarry<br />

(left) and SSQ founder Ahmed El-Helw.<br />

outstanding slate, I needed a<br />

world-class quarry, run by<br />

people with uncompromising<br />

standards.<br />

In the months that followed, I set out on a<br />

journey to find the highest quality natural slate<br />

that Spain had to offer.<br />

I commissioned a comprehensive geological<br />

survey of the country’s slate-quarrying<br />

heartlands with the aim of finding the best of the<br />

best, and it was through this, and the help of<br />

Lisardo García and Belen Requejo of the newlyfounded<br />

SSQ Spanish office, that I first<br />

discovered Del Carmen.<br />

Doing the deal<br />

As quarries go, Del Carmen had it all –<br />

uncompromising quality standards, decades of<br />

expertise, and the most stunning blue-black slate<br />

with the longevity to last up to a century.<br />

And it was thirty years ago this year that I first<br />

met with the quarry’s owners to discuss how we<br />

could work together.<br />

At the time, Del Carmen exclusively supplied the<br />

French market. The French take slate extremely<br />

seriously. They’re the biggest slate importers in<br />

the world and have some of the strictest quality<br />

standards on Earth. If a slate isn’t at least of<br />

specification standard, it isn’t even allowed to<br />

enter the country.<br />

In quality terms, it meant that I’d found what I<br />

was looking for – the finest slate Spain had to<br />

offer.<br />

However, the next problem was convincing Del<br />

Carmen to supply me some of the outstanding<br />

material that they were selling extremely<br />

successfully in France.<br />

Continued from page 42<br />

Luckily for me, I got on extremely well with<br />

Manuel Maestre Vega, Del Carmen’s founder,<br />

from the very first meeting. It immediately<br />

became clear we had similar values, and he and<br />

his team obviously appreciated my passion for<br />

the product they had to offer.<br />

After a short period of negotiation, we shook<br />

hands on a deal that would see my company SSQ<br />

become the UK supplier of Del Carmen slate.<br />

My final challenge was convincing Del Carmen to<br />

move away from the very small, expensive slates<br />

they’d been selling into the French market. Over<br />

time, I managed to persuade them that the UK,<br />

US and Australian markets demand larger sizes!<br />

Today, we’re buying in more than 65 loads a<br />

month, and over the next three years we expect to<br />

exceed 100 – we would’ve reached that number<br />

already if it wasn’t for COVID.<br />

Three decades of trust<br />

Such was the trust and respect between Manuel<br />

and I that we never signed a formal contract. For<br />

thirty years we’ve worked together without any<br />

need for lawyers or pieces of paper.<br />

The Del Carmen family have integrity and<br />

principles and I’m proud to be partnered with<br />

them. They’ve been extremely supportive of me<br />

over the years.<br />

I recall a time when I’d brought an Australian<br />

customer of mine to Spain to meet Manuel. My<br />

client joked that they should buy directly from Del<br />

Carmen instead, but Manuel said “no, I only<br />

supply Ahmed, he’s my customer” – and he was<br />

serious.<br />

Today, Del Carmen crowns government buildings,<br />

very old listed buildings, and famous churches<br />

across the world, not only in the UK but also<br />

Australia, New Zealand, the US, Japan, Fiji, China<br />

and the Middle East.<br />

It’s the Rolls Royce of roofing materials. The<br />

quality is like diamond and we’re proud to market<br />

it all around the globe.<br />

All being well, we’ll be heading to Spain later this<br />

year to mark the three decade milestone properly.<br />

It’s my hope that SSQ will still be supplying<br />

exceptional Del Carmen slate in another thirty years.<br />

CUPA’S SLATE SOLUTION<br />

CUPA PIZARRAS’ products have been<br />

specified extensively across a major<br />

development and refurbishment project on<br />

the grounds of the Tregenna Castle Resort.<br />

Delivering spectacular views of the St Ives<br />

coastline, the Castle Approach Estate is a new<br />

collection of lodges built in the grounds of the<br />

historic Tregenna Castle Resort. In looking to<br />

complete the exclusive lodges, Summit Roofing<br />

Solutions utilised a number of CUPA PIZARRAS’<br />

products. Likewise, the project team also chose to<br />

use the company’s natural slate to complete a<br />

renovation of Tregenna Castle’s original roof.<br />

The lodges and castle are subject to difficult<br />

coastal conditions, so the project team needed<br />

access to roofing solutions that could deliver longlasting,<br />

durable performance. Likewise, given<br />

Tregenna Castle’s status as a Grade II listed<br />

property, the team had to ensure that any selected<br />

products were able to deliver a traditional<br />

aesthetic, whilst still providing modern<br />

performance. Therefore, roofs on the lodges at<br />

Tregenna Estate exclusively used CUPA<br />

PIZARRAS’ 400mm x 200mm CUPA 12 natural<br />

slates, fixed using 100mm stainless steel hooks<br />

that were also produced and supplied by CUPA<br />

PIZARRAS. Notably, Summit Roofing Solutions<br />

was able to install the natural slate as a closed<br />

mitred hip system. In doing so, the project team<br />

ensured that all slates lined up perfectly with one<br />

another, which is only possible on account of the<br />

products’ uniform size and quality.<br />

www.cupapizarras.com<br />

WEATHERTIGHT PROTECTION<br />

A technically advanced, high-performance, hybrid roofing membrane from global building product manufacturer<br />

Sika, provided the watertight finish for a new school which was built using innovative offsite construction<br />

techniques.<br />

The newly-constructed King Edward VI Northfield School for Girls in Birmingham, which was designed by architect Atkins Global on behalf of client<br />

Acivico Group, replaces Turves Green Girls’ School. To meet performance and programme goals for the building’s construction, a hybrid design was<br />

devised by offsite construction and modular specialists, Innovaré. Innovaré’s hybrid system included integrated BBA-Certified i-SIP panels, hollow core<br />

concrete plank floors, and a lightweight timber cassette roofing system. This hybrid method of construction, which meant most of the new school<br />

structure was manufactured offsite, offered a radically quicker speed of build, reducing preliminary and overall costs. It also ensured the building’s<br />

performance and programme goals were met. Sika is ideally placed to support offsite construction projects. Its Modern Methods of Construction (MMC)<br />

Division is specifically tasked to work with offsite manufacturing and assembly companies to consider how Sika products could be used as part of the<br />

building process in this fast-growing sector. Sika’s 4mm elastomeric and plastomeric bituminous hybrid membrane, SikaBit Pro 940, provided the<br />

watertight finish for the new building’s energy-efficient roofing system, which integrates timber cassettes with i-joists. https://gbr.sika.com<br />

WATERPROOF SEAL FOR PRIME MANCHESTER PROJECT<br />

BriggsAmasco delivered the watertight roof system for a stylish addition to Manchester city centre’s building portfolio.<br />

Eleven York Street features a desirable meld of prime office space, retail units and ‘Grade A accommodation’. The high-profile development<br />

– which occupies a 26,000m² area – was delivered by Kier Construction on behalf of Aviva Investors. AHR Architects was responsible for<br />

its design. BriggsAmasco was selected to waterproof the building’s 1,200m² main roof and two plant rooms totalling 300m². With work<br />

beginning at the height of the coronavirus pandemic, Briggs’ workforce was reduced in number to improve social distancing and enhance<br />

on-site safety. This presented a challenge, as the pressure was on to steer the works programme back on track. For the main building,<br />

BriggsAmasco teams installed IKO Permascreed to the roof’s 1200m² concrete surface. The mastic asphalt-based levelling screed not only provided a stable<br />

base for the covering waterproofing system, it enabled Briggs’ installers to create falls and ensure appropriate water run-off. This was followed by the<br />

installation of an IKO Permatec, hot-applied membrane, which was finished with a mix of ballast and paving. The two plant room roofs, which featured a<br />

plywood overlay to a metal deck, were also supplied with an IKO Permatec, hot-applied membrane and a ballast and paving finish. A fifth-floor terrace requiring<br />

public access was installed with the same IKO Permascreed/IKO Permatec/ballast/paving combination as the main roof. Each of these works was carried out by<br />

BriggsAmasco in a skilled and timely manner. www.briggsamasco.co.uk<br />

Digital Processes<br />

DIGITAL RECONSTRUCTION<br />

TO FACE THE FUTURE<br />

Architectural wall cladding specialist Spanwall has embarked on a complete restructuring<br />

of its production operations, led by Manufacturing Director, David Clark, to increase<br />

efficiencies and assist customers.<br />

Founded in 1967, Spanwall’s architectural<br />

wall claddings feature on iconic buildings<br />

around the world, from Titanic Belfast to<br />

Riyadh Metro. The company’s products are<br />

specified by architects and designers working on<br />

behalf of clients including Google, Apple, Audi and<br />

British Airways, and are renowned for their<br />

precision engineering and their ability to create<br />

performance products that deliver the aesthetic<br />

of the future.<br />

Spanwall received significant investment from<br />

Cordovan Capital Management in <strong>March</strong> 2021 and<br />

David Clark was recruited back into the company in<br />

September ’21 to lead the manufacturing<br />

and digital transformation process.<br />

David began his career with<br />

Spanwall in the late ‘90s and<br />

then moved to The McGrath<br />

Group for 9 years, then on to The<br />

McAvoy Group for a decade. He<br />

returns to Spanwall with a great<br />

deal of experience in building and<br />

construction product manufacturing.<br />

“Over the years, the business has gone through<br />

significant change, with periods of expansion and<br />

contraction that have been accommodated by<br />

reactive changes on the factory floor. Coming in<br />

for the outside I could see, just by looking inside<br />

the unit, an urgent need to reorganise and bring<br />

the operations into line with the latest digital<br />

technology,” David explained.<br />

“Manufacturing equipment and capabilities have<br />

been added to, however we know that we need to<br />

make some changes to improve the flow of<br />

products and processes – it was simply not as<br />

efficient as it should have been. Added to that,<br />

Left: David Clark, Manufacturing Director at Spanwall. Spanwall’s products are specified globally.<br />

manufacturing documentation<br />

and information was still<br />

paper-based, with our projects<br />

containing multiple parts and<br />

excessive copies of paper drawings<br />

were moving around every corner of<br />

the manufacturing plant. Tracing<br />

the movement of a part on its<br />

journey through production<br />

actually created an image that<br />

resembled a spider’s web!”<br />

Factory floor layouts<br />

“From my first week into the job I<br />

could immediately see we had to restructure the<br />

factory and become more efficient in how we<br />

work end to end. Twinned with layout changes, we<br />

needed to rethink the process to manage<br />

products into, through, and out of the business,<br />

and to develop an information management<br />

system that improves efficiency and control<br />

throughout the manufacturing processes,”<br />

continued David.<br />

To assist in developing a forward strategy, the<br />

company commissioned Pinnacle Growth Group<br />

to conduct a ‘Current State Review’ and<br />

outline potential next steps. “The<br />

report was sobering,” admitted<br />

David. “It provided a very<br />

forthright review of the current<br />

status, the business risks<br />

associated and then provided<br />

reasoned recommendations with<br />

suggested achievement dates. It<br />

was a very useful exercise.<br />

“We worked together within the company to agree<br />

on a vision for the future factory layout, to be<br />

achieved in phased stages. The first phase of this<br />

was to challenge the current state and develop a<br />

new factory layout that provided an efficient flow of<br />

materials through the manufacturing processes.”<br />

46 TC MARCH <strong>2022</strong>


Spanwall has invested heavily in systems and the factory layout to increase efficiencies and ensure it can meet the demands of the market: “Spanwall has an unrivalled reputation for producing<br />

bespoke products for iconic and difficult projects but we want to be able to apply the same credentials to our standard products, and that is where digital construction tools come to the fore.”<br />

Manufacturing Execution System<br />

It was also crucial to the restructuring<br />

programme to modernise information systems<br />

within the factory operations, and David has<br />

initiated a complete shift away from paper-based<br />

to digital information with the implementation of<br />

a Manufacturing Execution System, or MES.<br />

Using information capture, open accessibility and<br />

information analysis, the MES will connect data<br />

to provide deeper insight into production and<br />

drive process improvements. It will provide a<br />

real-time view of operations, facilitate<br />

information exchange and communication, and<br />

will report on Key Performance Indicators to<br />

analyse operator and business performance.<br />

“From a starting point of relying totally on paper<br />

in a very rudimentary system, the move to the<br />

MES will transform operations,” continued David.<br />

“It will replace paper with a visual dashboard<br />

showing how production is proceeding in realtime<br />

and effectively form a very strong digital<br />

backbone to improve manufacturing operations.<br />

“We aim to introduce screens on the floor that all<br />

operators will be able to log into with a QR code,<br />

access and see the information they need and log<br />

out when their part of the operations process is<br />

completed. Effectively, we will know where each<br />

production part is in the factory, what stage of<br />

the process it is at, when it will move to the next<br />

stage and when the process is complete.<br />

“The system can also identify errors and<br />

bottlenecks, analyse cycle times, improve<br />

forecasting and provide accurate, achievable lead<br />

times to customers. In effect, the MES will make<br />

all our operations transparent, more accurate and<br />

more efficient for our business and our<br />

customers.”<br />

Digital construction development<br />

Digital construction is not exactly new, for<br />

example, programmes like AutoCAD and BIM<br />

systems have long been widely utilised in all<br />

aspects of the construction industry. In essence,<br />

it is ‘the use and application of digital tools to<br />

improve the process of delivering and operating<br />

the built environment’. What is new is the pace at<br />

which digital construction methods and<br />

processes are emerging and developing.<br />

“When I first worked for Spanwall, over 20 years<br />

ago, I was using 3D modelling programmes and<br />

doing what would now be called BIM. The tools<br />

are in the business, and the ambition is to better<br />

leverage them to improve our digital design<br />

capabilities. Changing how and how much these<br />

tools are used is an integral part of the<br />

restructuring programme to improve our product<br />

offering and customer experience.<br />

“Spanwall has an unrivalled reputation for<br />

producing bespoke products for iconic and<br />

difficult projects, but we want to be able to apply<br />

the same credentials to our standard products<br />

and that is where digital construction tools come<br />

to the fore. We need to draw smarter at an early<br />

stage and drive standardisation into the<br />

manufacturing process.<br />

“Potentially the most important area to focus on<br />

will be closer collaboration with clients and,<br />

through that, integrating their digital work into our<br />

system. Virtually every client, architect and<br />

designer that we interact with on a project will<br />

have their own BIM processes to draw buildings<br />

and components. However, as manufacturers we<br />

haven’t yet created a streamlined workflow from<br />

our customers to harness efficiencies. Clearly,<br />

there is a broken link and a lot of duplicated<br />

effort. We want to change that, generating<br />

efficiencies and learning through collaboration.<br />

“Spanwall has been very successful over its 50<br />

years, but it hasn’t really shouted loud about its<br />

achievements and capabilities. Now, under new<br />

ownership, we’re facing up to an automatic<br />

challenge to the status quo on many levels of the<br />

business. The vision for Spanwall’s future will<br />

take the company to another level. It’s a<br />

challenge I am relishing.”<br />

Digital Technology<br />

A LEGACY OF INTEGRITY<br />

Graham Laws, Technical Director at Siderise Insulation, discusses the many benefits of<br />

remote tools such as the Siderise Inspection App for contractors and installers...<br />

When it comes to installing passive fire<br />

protection in the building envelope, the<br />

job isn’t finished once the products are<br />

in and the workers have left site. Playing such a<br />

crucial role in the long-term safety of the building<br />

and its occupiers, it is vital to ensure elements<br />

such as cavity barriers and firestops have not<br />

only been specified and fitted correctly, but that<br />

information about what they are, how they<br />

perform, and where they have been used must be<br />

preserved for the property’s lifetime. This will<br />

allow building owners to both demonstrate the<br />

passive fire safety of their building and make<br />

informed decisions on how any future<br />

refurbishment or extension projects should be<br />

approached to maintain that level of safety.<br />

In the past, this would have consisted of<br />

arranging onsite inspections for each project, and<br />

maintaining and handing over files of relevant<br />

product information, locations etc. However,<br />

digital tools are now streamlining this process,<br />

alleviating the pressure for contractors, and<br />

providing a clear trail of product information.<br />

Digital database<br />

In recent years, the importance of accurate and<br />

accessible product data in construction has been<br />

made increasingly clear – especially when it<br />

comes to fire safety. Whilst much of the focus has<br />

been on specification, installers and building<br />

owners also need access to this valuable<br />

information both onsite and during future works.<br />

Digital identification platforms, such as BSI<br />

Identify, can provide a straightforward solution to<br />

product traceability. Dedicated QR codes are<br />

added to products which are linked to BSI UPINs<br />

(unique persistent identification numbers) which<br />

are applied to every construction product within<br />

the BSI Identify database. When scanned, this<br />

will take the user to the exact product data<br />

supplied by the manufacturer, attributable to the<br />

Remote tools such as the Siderise Inspection App can help<br />

ensure high levels of workmanship, without requiring an<br />

onsite inspection.<br />

day it was manufactured, whether that was<br />

yesterday or a decade later. This ensures that<br />

anyone can easily find all the correct product<br />

information relating to specification, testing,<br />

installation, and maintenance – including historic<br />

performance credentials, safety data and more. In<br />

addition to ensuring access to correct data in the<br />

future, it has “real time” value allowing access to<br />

information that will assist in on site production<br />

identification and application, such as installation<br />

videos or standard details. Of course, it is then the<br />

responsibility of the installer to then follow and<br />

evidence best practices – another step that can<br />

be supported with simple onsite digital tools.<br />

Onsite support<br />

Audits and inspections are a regular requirement<br />

for many projects. However, with deadlines to<br />

meet, it can be tempting to skip a full inspection<br />

by a product manufacturer – which are often<br />

offered as an additional service – and instead rely<br />

on the Building Control inspection which typically<br />

takes place when the passive fire protection<br />

products have been covered by the facade.<br />

However, manufacturer-developed inspection<br />

apps, such as the one we offer at Siderise, can<br />

allow for this extra layer of assurances without the<br />

extra time and hassle of arranging an in-person<br />

visit from their site services.<br />

Whilst some projects may need or prefer an inperson<br />

inspection, our inspection app offers<br />

contractors a simple way to record the progress<br />

and quality of the installation of our standard fire<br />

stop, cavity barrier and acoustic barrier systems.<br />

Freely available from the Apple Store and Google<br />

Play store, it enables users to capture images as<br />

each area/element is installed and update the<br />

data input fields using their smartphone or tablet.<br />

The app then immediately turns this into a<br />

comprehensive report which can be reviewed<br />

offsite by our technical team to ensure the<br />

installation meets recommendations and identify<br />

any areas which need further remedial actions to<br />

get them up to standard. This takes around 3<br />

days and further reports can be submitted to<br />

verify any remedial work. As well as streamlining<br />

the inspection process, the report generated by<br />

the app provides a valuable visual record of<br />

hidden elements of a construction once the build<br />

is complete. This can be handed over to the<br />

building owner, making it clear to them exactly<br />

what’s in the building and how it was installed.<br />

A lifetime of information<br />

As the people who take a building from a concept<br />

to a functional structure, contractors play a vital<br />

role in not only ensuring the passive fire safety of<br />

the building structure, but in maintaining that allimportant<br />

‘golden thread’ of information that is<br />

key to delivering a safer built environment, both<br />

now and in the future.<br />

The Siderise Inspection App and involvement with<br />

BSI Identify is part of our extensive range of<br />

technical and site support services, which also<br />

includes project and system testing, review of<br />

project specific details, remote and in-person<br />

training, and toolbox talks.<br />

REAL HOMES, REAL STORIES, REAL BENEFITS<br />

Home transformations and improvements<br />

have been a major outcome of the events of<br />

the last two years. Freefoam Building<br />

Products says homes have become places of<br />

work and leisure with people wanting to make<br />

their homes more spacious, convenient,<br />

comfortable, low maintenance and attractive,<br />

and many have used funds normally spent on<br />

travel and holidays on home improvements.<br />

To illustrate this trend, Freefoam Building<br />

Products has developed two new case studies<br />

featuring cladding and fascia products to<br />

highlight how a large number of homeowners all<br />

over the UK are using low maintenance, cost<br />

effective PVC to update and re configure their<br />

homes, to ensure they are fit for purpose now and<br />

in the future.<br />

The first case study features Freefoam Fortex<br />

weatherboard cladding in subtle Misty Grey fitted<br />

on two refurbished and extended dormers.<br />

With teenage children, the homeowner needed<br />

more space so decided to extend the dormers to<br />

create larger, more adaptable bedrooms. He<br />

explained: “We looked at replacing with tiles and<br />

also thought about render, but then found<br />

information about cladding. Cost was a factor and<br />

we liked the Freefoam cladding as it was suitable<br />

for our budget.”<br />

Above: Freefoam’s Fortex weatherboard cladding in subtle<br />

Misty Grey fitted on two refurbished and extended dormers.<br />

Right: Freefoam’s PVC fascia, soffit and gutter fitted on a<br />

property in Yorkshire, installed by a local Freefoam<br />

Registered Installer.<br />

The second case study shows Freefoam PVC<br />

fascia, soffit and gutter fitted on a property in<br />

Yorkshire, installed by a local Freefoam<br />

Registered Installer.<br />

The homeowners, both recently retired, bought<br />

their home from new over 20 years ago. Built with<br />

PVC windows, but featuring wood fascia and<br />

soffit, the roofline had over time degraded and<br />

needed regular maintenance. Part of their<br />

retirement plans were to update and modernise<br />

the house, and to make sure the maintenance was<br />

kept to a minimum to allow more time for travel.<br />

The homeowner explained: “We liked the<br />

Freefoam products. We chose white and were<br />

pleased to find out that it came with a 50-year<br />

guarantee and felt reassured that there would be<br />

no more tricky and costly maintenance. One of<br />

the other benefits for us was that the Freefoam<br />

installer organised the whole job. They arranged<br />

the scaffolding contractor so we only had to deal<br />

with one company. The fitting team were great<br />

and worked hard and got the job done quickly and<br />

efficiently, with not too much mess. We’re really<br />

pleased with the results.“<br />

Louise Sanderson, Freefoam UK Marketing<br />

Manager, explained: “Our marketing team know<br />

how valuable homeowner testimonials and case<br />

studies can be. We focus on generating good<br />

quality, relevant case studies to showcase our<br />

range of products and illustrate how they are<br />

being used to transform and improve homes<br />

around the country. We work closely throughout<br />

the whole supply chain with suppliers, installers<br />

and homeowners to shine a light on the excellent<br />

work that is happening throughout the UK.”<br />

All You Need to Know About...<br />

HOW LIFE CYCLE ASSESSMENT IS<br />

REPORTED IN EPDS<br />

In this ongoing series, Rob Firman, of Polyfoam XPS, looks at different aspects of flat roofing<br />

design and construction and helps to demystify them, this month explaining how life cycle<br />

assessment is reported in EPDs and what roofers need to know...<br />

Life cycle assessment, or LCA, is the analysis<br />

of a construction product’s environmental<br />

impact. It is done across five stages called<br />

product, construction process, use, end of life, and<br />

the circular economy. The assessment results are<br />

reported in an environmental product declaration<br />

(EPD), which presents them in a standard format<br />

for some or all of the stages.<br />

The results are reported across four modules, A to<br />

D (module A includes two of the five stages).<br />

Each module contains several numbered subcategories.<br />

Manufacturers choose the scope of their<br />

LCA reporting, but new rules will make it<br />

compulsory to report across all stages and modules.<br />

Modules A, B and C<br />

Module A of life cycle assessment comprises the<br />

‘product’ and ‘construction process’ stages,<br />

encompassing activities up to a building’s<br />

practical completion.<br />

For the product stage, that involves: A1 (raw<br />

material extraction and supply), A2 (transport to<br />

manufacturing plant), and A3 (manufacturing and<br />

fabrication). Manufacturers can lower their<br />

impact here by acting responsibly, with a<br />

transparent and traceable approach to raw<br />

material sourcing and processing.<br />

Construction process is A4 (transport to project<br />

site) and A5 (construction and installation<br />

process), and covers a product leaving the<br />

factory, being delivered to site and its installation<br />

as part of the finished building.<br />

The use stage features seven modules, B1 to B7,<br />

dealing with use, maintenance, repair,<br />

replacement and refurbishment, together with<br />

operational energy and water use.<br />

A product like insulation is part<br />

of the building fabric – it should<br />

last for the life of the building<br />

and require little or no<br />

maintenance, repair, replacement<br />

or refurbishment. As a result, its<br />

use stage emissions should be relatively<br />

low. By contrast, products with shorter life spans,<br />

requiring regular maintenance and replacement,<br />

are likely to incur more environmental impact<br />

during the building’s life.<br />

Modules C1 to C4 are the ‘end of life’ stage,<br />

addressing deconstruction and demolition;<br />

transport to a disposal facility; waste processing<br />

for reuse, recovery or recycling; and disposal.<br />

How we deal with buildings at the end of their<br />

useful life is becoming increasingly important,<br />

especially as the construction industry looks to<br />

reduce waste associated with demolition,<br />

preserve existing resources, and minimise the<br />

extraction and use of new raw materials.<br />

Module D and the circular economy<br />

The final module – module D – has the full title of<br />

‘Benefits and loads beyond the system boundary’.<br />

It reflects a shift to the circular economy from the<br />

linear economy, when the materials and products<br />

can have their useful life extended across<br />

multiple projects.<br />

Currently, module D is unlikely to be reported in<br />

many EPDs because many construction products<br />

are not designed with reuse, remanufacturing, or<br />

even recycling, in mind.<br />

The construction industry is talking a lot more<br />

Left: Rob Firman, Polyfoam XPS.<br />

about embodied carbon, but it’s<br />

worth bearing in mind that it’s<br />

possible to choose a low<br />

embodied carbon product and<br />

still only be able to use it once.<br />

If low embodied carbon products<br />

are specified but a lot of them need to<br />

be used, is that a sustainable choice?<br />

A simplistic question like that doesn’t reflect the<br />

complexity of construction projects, but it’s an<br />

indication of how our thinking needs to shift in the<br />

transition to a net zero future.<br />

“The focus now needs<br />

to be on making sure<br />

assessment and<br />

reporting are as<br />

comprehensive as<br />

possible”<br />

The number of EPDs available has grown<br />

substantially in the last ten years, but the scope<br />

of LCA reporting in each EPD is not consistent.<br />

When data is reported for more stages, the<br />

picture of the environmental impact of the<br />

product being assessed is more complete.<br />

Arguably, now that EPDs are more widely<br />

available, the focus now needs to be on making<br />

sure assessment and reporting are as<br />

comprehensive as possible, from module A<br />

through to module D.<br />

Insulating Listed Properties<br />

ASK THE A. PROCTOR GROUP<br />

In this series, the A. Proctor Group will look at some commonly held myths surrounding the<br />

contracting world concerning thermal and acoustic insulation, condensation control, and fire<br />

protection. In this first article, the experts at A. Proctor Group tackle the question: ‘Is it true<br />

that you can’t improve the thermal performance of a house registered as a listed building?’<br />

Solid wall construction – the<br />

external/internal insulation challenge<br />

Many listed buildings were constructed<br />

using solid masonry walls. Unlike<br />

framed constructions or cavity walls –<br />

where insulation can be installed within the<br />

structure – solid masonry walls need to be<br />

insulated internally or externally. Both options<br />

require spatial and aesthetic changes that may<br />

not be acceptable or viable in listed properties.<br />

External insulation would typically be covered in a<br />

render, which would change the external<br />

appearance of the building. This difficulty is<br />

compounded by the fact that solid masonry walls<br />

have more complex requirements in terms of<br />

managing moisture than other wall types.<br />

Internal approaches typically include applying<br />

insulated plasterboard directly onto the wall or<br />

introducing battens or even free-standing framed<br />

systems. Unfortunately, these options can be<br />

impractical due to space constraints, with some<br />

framed options intruding into the room by several<br />

hundred millimetres. The resulting space<br />

constraints can prove challenging, particularly<br />

around windows and doors. The A. Proctor Group<br />

has been pioneering thermal solutions for over<br />

half a century and developed the Spacetherm<br />

range of high-performance insulation solutions<br />

particularly suited to meet this challenge,<br />

including Spacetherm WL (Wall Liner) and<br />

Spacetherm Multi. Spacetherm WL is fixed to the<br />

internal surfaces of existing solid walls without<br />

the need for mechanical fixings.<br />

Consisting of a Spacetherm aerogel insulation<br />

blanket bonded to 3mm Magnesium Board (MgO),<br />

at just 13mm thick, there is often no need to<br />

remove skirting boards and cornices, saving time<br />

and cost. Typically, a solid wall will have a U-<br />

value of around 2.1 W/m² K. Following the<br />

application of Spacetherm WL this can be<br />

reduced to around 0.8 W/m² K, dependent on the<br />

wall structure.<br />

Spacetherm from A. Proctor Group was<br />

installed on Grade II listed Georgian<br />

townhouse in the historic city of Bath.<br />

Assessment methods – Hygrothermal<br />

performance<br />

Key guidance on assessment methods in relation<br />

to the risk of condensation in buildings is given<br />

within BS EN ISO 13788:2012 ‘Hygrothermal<br />

performance of building components and<br />

building elements. Internal surface temperature<br />

to avoid critical surface humidity and interstitial<br />

condensation. Calculation methods’.<br />

Contractors will be familiar with BS 5250: 2021<br />

Management of moisture in buildings - Code of<br />

practice. BS5250 highlights the need for greater<br />

accuracy of measurement as follows: ‘Designers<br />

should be aware that BS EN ISO 13788 considers<br />

only the risks arising from the diffusion of water<br />

vapour through the building fabric; it does not<br />

take account of the much greater risk of<br />

condensation occurring because of air leakage,<br />

which transports water vapour through gaps,<br />

joints and cracks in the building fabric.’<br />

Traditional methods of assessment have been<br />

based on the Glaser method – a standard static<br />

interstitial moisture calculation. More designers<br />

are recognising the limitations of this method,<br />

which offers a simplified approach, developed<br />

back in 1958 for use in lightweight buildings.<br />

Technology you can rely on from a brand<br />

you can trust<br />

The simplified calculation used by the Glaser<br />

method is based on average monthly<br />

temperatures, vapour pressure and steady state<br />

conduction of heat to determine if critical<br />

condensation points are reached within one year.<br />

The Glaser method identifies vapour diffusion,<br />

how easily water vapour can pass through the<br />

fabric of the building. However, limitations of this<br />

approach are that Glaser assumes vapour moves<br />

only one way (inside to outside). It completely<br />

omits the key feature of driving rain from its<br />

calculations, does not measure absorption or<br />

porosity, and therefore misses the potential risk<br />

attributed to the aspect of moisture storage.<br />

A standard that is increasingly recognised as the<br />

way to address this is BS EN 15026:2007<br />

‘Hygrothermal performance of building<br />

components and building elements. Assessment<br />

of moisture transfer by numerical simulation.’<br />

Hygrothermal assessment is based upon the<br />

analysis of heat, vapour, and moisture transfer<br />

through the elements of a building. The<br />

assessment data provides an accurate measure<br />

to the temperature, relative humidity, and water<br />

content within the elements of a building<br />

measured over a specified time.<br />

To provide contractors and designers with an<br />

accurate assessment, the A. Proctor Group uses<br />

WUFI software, which is fully compatible with BS<br />

EN 15026, and dynamically predicts moisture<br />

movement and storage as well as condensation<br />

for each location. The contractor can achieve a<br />

minute-by-minute prediction over a given period<br />

of years, and a worst-case scenario with the<br />

injection of a moisture source at the source to<br />

predict the robust drying out of the fabric build<br />

up. Using WUFI enables contractors to identify the<br />

likelihood and risks of condensation when<br />

considering solutions to improve the thermal<br />

performance of listed buildings.<br />

Case study: Grade II listed<br />

Georgian townhouse<br />

A solution to addressing the challenge of heating<br />

inefficiencies, major heat loss and high heating<br />

costs within listed buildings and solid wall<br />

dwellings was demonstrated following the<br />

refurbishment of a Grade II listed Georgian<br />

townhouse in the historic city of Bath.<br />

Property owner Mike Mower explained: “I<br />

obtained planning permission to insulate the top<br />

floor of my Grade II listed Georgian townhouse as<br />

it is single skin 6 Bath stone (Oolite) and very<br />

heat inefficient, all walls have the original lime<br />

render and skim and so they need to breathe.<br />

“The architect originally specified another<br />

insulation, but this would have required<br />

encroaching 100mm into the room and<br />

necessitate moving door frames and rebuilding<br />

window reveals. After extensive research, I<br />

identified the Spacetherm Multi aerogel product<br />

from the A. Proctor Group. The architect was so<br />

impressed by the thermal efficiency of the<br />

Spacetherm Multi. With a total thickness of<br />

20mm when rendered, this will not encroach<br />

onto the floor space, and the door frames and<br />

windows will not need to be altered.<br />

Subsequently we included Spacetherm Multi on<br />

the planning application as an alternative to the<br />

traditional insulation originally specified, which<br />

was approved by the Conservation Officer and<br />

Building Control.”<br />

Based on years of extensive research, the<br />

solutions developed by A. Proctor Group have<br />

busted the myth that you can’t improve the<br />

thermal performance of your historic listed<br />

buildings. Contractors can rest assured that<br />

there is a range of proven high-performance<br />

insulation solutions available.<br />

Knauf Insulation Tech Talk<br />

TOP TIPS FOR INSULATING A LOFT<br />

Faced with rising energy bills, many homeowners will be looking to increase the energy<br />

efficiency of their homes by insulating their lofts. So this month, Bradley Hirst, Technical<br />

Services Manager at Knauf Insulation, gives his six top tips for a successful loft installation.<br />

• Meet the minimum standards for<br />

thermal performance<br />

The minimum standards for thermal performance<br />

are listed in Approved Document L of the Building<br />

Regulations. From June <strong>2022</strong>, renovated roofs –<br />

which includes lofts insulated at ceiling level –<br />

must achieve a U-value of 0.16W/m²K. For a<br />

typical loft, this can be achieved by installing<br />

Knauf Insulation’s Loft Roll 44 at a depth of<br />

270mm or Loft Roll 40 at a depth of 250mm.<br />

Glass Mineral Wool insulation should<br />

be installed in two layers. The first<br />

layer should be the same depth as<br />

the joists<br />

• Always unwrap Mineral Wool insulation<br />

in the loft<br />

Our Glass Mineral Wool insulation is<br />

compressed so there’s more product<br />

per pack, which means you can fit<br />

more insulation into your van –<br />

which also reduces transportrelated<br />

carbon emissions. But when<br />

you unwrap it, our Loft Roll insulation<br />

will recover to up to ten times its<br />

compressed thickness. So always unwrap it<br />

where you plan to install it!<br />

• Layer insulation at right angles<br />

The first layer of insulation should be installed<br />

between the joists to the same depth as the joist.<br />

So, if your joist is 100mm deep, your first layer of<br />

insulation should also be 100mm deep.<br />

Subsequent layers should be installed at a right<br />

angle to the first layer, completely covering the<br />

joists.<br />

• Make sure there are no gaps<br />

Unintended air gaps reduce thermal, fire safety<br />

and acoustic performance, so make sure the<br />

insulation is fitted tightly against the joists and<br />

that rolls are butted together. Remember to tuck<br />

the insulation down at the roof perimeter so it<br />

“Unintended air gaps reduce thermal, fire<br />

safety and acoustic performance, so make<br />

sure the insulation is fitted tightly against<br />

the joists and that rolls are butted together”<br />

meets the insulation in the wall head to prevent<br />

thermal bridging.<br />

• Don’t block ventilation<br />

To prevent condensation,<br />

make sure air vents<br />

are unobstructed<br />

and if the roof is<br />

lined with sarking<br />

felt, leave an air gap<br />

at the eaves to ensure<br />

continuous ventilation of<br />

the roof void.<br />

• Watch out for electrical cables<br />

High voltage electrical cables should be rerouted<br />

and laid over the top of the insulation to prevent<br />

risk of overheating or fire. One of the benefits of<br />

our Mineral Wool insulation is that it is noncombustible<br />

with the<br />

best possible<br />

Euroclass A1 and A2-<br />

s1,d0 reaction to fire<br />

classifications. This<br />

means it will not<br />

contribute to the development or<br />

spread of fire should it occur.<br />

Project Focus: Wilmcote House<br />

ROCKWOOL SOLUTIONS SUPPORT<br />

RESIDENTIAL ENERPHIT PROJECT<br />

A combination of ROCKWOOL External Wall and Flat Roof insulation, together with a<br />

selection of the company’s fire stopping and fire protection products, helped the largest<br />

residential EnerPHiT project in the world (the retrofit equivalent of Passivhaus) be delivered<br />

with residents in-situ.<br />

High-rise, high-density housing estates<br />

built by local authorities in the 1960s<br />

remain a prominent feature of Britain’s<br />

urban landscape – but the thermal performance<br />

of these buildings often falls below modern<br />

standards.<br />

One such development is Wilmcote House in<br />

Portsmouth, which required significant<br />

improvements including retrofit insulation<br />

upgrades to ensure quality of life for residents.<br />

Across a four-year programme, over 100<br />

residences within Wilmcote’s three 11 storey<br />

blocks were set for upgrades to provide<br />

comfortable, safe and thermally-efficient homes<br />

for residents for years to come.<br />

Wilmcote House would become the largest<br />

EnerPHiT (the retrofit equivalent of Passivhaus)<br />

standard scheme yet delivered with residents insitu.<br />

A key objective of the major renovation,<br />

designed and led by ECD Architects, was the<br />

creation of an environment capable of supporting<br />

the health and wellbeing of tenants.<br />

A non-combustible refurbishment and<br />

deep retrofit solution<br />

Wilmcote House was identified as one of<br />

Portsmouth City Council’s high-rise developments<br />

most urgently in need of improvement. Fuel<br />

poverty was a cause for concern, as well as<br />

damp, mould and condensation. The University of<br />

Southampton installed data loggers into<br />

properties which revealed compelling results.<br />

Residents were not heating their homes to the<br />

World Health Organisation comfort level of 18°C,<br />

as their electric heating was too expensive.<br />

Above: a combination of several products and systems, including a Rockpanel cladded façade system and a combination of<br />

ROCKWOOL External Wall and Flat Roof insulation, were utilised to improve the performance of Wilmcote House in Portsmouth.<br />

Following a detailed appraisal, Portsmouth City<br />

Council engaged ECD Architects to design and<br />

lead a substantial renovation to upgrade the<br />

scheme to the ambitious EnerPHiT standard in a<br />

fabric first approach. They targeted a reduction in<br />

dwelling heating demand by 90% and a minimum<br />

30-year extension to the lifetime of the estate,<br />

with the entire project carried out as residents<br />

remained in-situ.<br />

ECD’s whole building EnerPHiT solution centred<br />

on deep retrofit. This involved the insulation of<br />

Wilmcote House using a combination of several<br />

products and systems, including a Rockpanel<br />

cladded façade system and a combination of<br />

ROCKWOOL External Wall and Flat Roof insulation,<br />

together with a selection of the company’s fire<br />

stopping and fire protection products.<br />

The ROCKWOOL external insulation was fitted as<br />

a 300/400mm zone fixed to newly assembled,<br />

external steel frames to insulate and wrap the<br />

entire building. The result is improved thermal<br />

performance and exceptional air tightness,<br />

reducing draughts, condensation and mould<br />

growth.<br />

Other works at Wilmcote House included roof<br />

replacement, installation of triple glazed<br />

windows, extension of the living areas, and more<br />

efficient heating and hot water, and adjustment of<br />

the ventilation with heat recovery system.<br />

As the largest residential EnerPHiT project<br />

delivered with residents in-situ in the world,<br />

ROCKWOOL says the project is a testament to<br />

what can be achieved by taking a holistic, fabric<br />

first, people-focused approach to building<br />

refurbishment.<br />

INSULATION FACTS<br />

, or VIP’s, have been used in warm and<br />

inverted roof construction for a while now, they even have their own<br />

<br />

<br />

years they remain a product not all contractors will have worked with,<br />

primarily because they are much more expensive than conventional<br />

roof insulation.<br />

The high cost is primarily due to the slow production speed; each panel<br />

is formed individually from dried silica sand compressed into a square<br />

or rectangle before being wrapped in an aluminium foil. The air is then<br />

sucked out of the foil wrapped block and the foil sealed to create a<br />

<br />

<br />

<br />

ROCKWOOL’s Stone wool EWI system was installed at Wilmcote House.<br />

Raising living standards<br />

The living environment and quality of life of residents has dramatically<br />

improved not just the physical condition of the housing stock; community<br />

engagement was a major theme throughout the project.<br />

Dialogue was maintained throughout the build with residents of Wilmcote<br />

House, and anecdotal evidence and feedback received so far has the<br />

project already proving to be a big success, as residents in completed<br />

properties experience the positive impacts on their health, wellbeing and<br />

reduced fuel bills.<br />

The refurbishment has brought the community together by improving the<br />

appearance of the estate and investing occupants with a greater sense of<br />

pride in their surroundings.<br />

As a testament to its success the scheme has received two RICS awards -<br />

one for Design Through Innovation, another for Regeneration, and it also<br />

secured a Constructing Excellence Award for Sustainability. The social and<br />

performance outcomes of the project will continue to be monitored by a<br />

partnership between ROCKWOOL, the London School of Economics (LSE),<br />

and the University of Southampton.<br />

<br />

<br />

<br />

<br />

<br />

<br />

jigsaw puzzle. The other challenge is that you cannot puncture the VIP for<br />

the same reason you cannot cut it – you eliminate the vacuum that creates<br />

<br />

There are currently a number of methods used to reduce the potential to<br />

puncture the aluminium foil:<br />

• – this only protects the top and bottom of<br />

the VIP, leaving the sides unprotected from potential damage.<br />

• – a higher than normal density PIR encapsulates s<br />

the VIP. This provides protection on all sides of the VIP but increases the<br />

<br />

<br />

<br />

• – the VIP is coated in a waterproof elastomeric<br />

coating. This method protects all sides of the VIP and is much thinner<br />

than PIR encapsulation. These VIP’s are widely used in inverted roof<br />

<br />

<br />

<br />

<br />

<br />

<br />

<br />

make a good margin on the VIP insulation but the contractor needs to<br />

ensure that they allow more time for installation and that the installers s<br />

know the VIP has to be handled with care. Damaging a few VIP panels<br />

<br />

<br />

than adding to it; but the high cost is also a good way to get the main<br />

contractor to protect the roof from other trades!<br />

ROCKWOOL’S SUSTAINABLE GAINS<br />

ROCKWOOL Group’s Sustainability Report for 2021 provides third-party verified data showing<br />

how the company’s products make a quantifiable impact toward achieving the UN Sustainable<br />

Development Goals. The company says the report also shows the good progress ROCKWOOL is<br />

making towards meeting its own sustainability goals.<br />

CEO Jens Birgersson commented: “Considering that buildings account for 28 per cent of global emissions and that in the EU alone, around 75 per cent of<br />

buildings are energy inefficient, our products play a key role in combatting climate change by reducing energy consumption in buildings. The building<br />

insulation we sold in 2021 will continue to save the annual energy consumption of more than one million homes, for the lifetime of the insulation.”<br />

ROCKWOOL says getting it right on renovation requires that the renovations qualify as “deep”, meaning achieving energy savings of at least 60 per cent;<br />

and that the materials used are healthy, fire resilient and circular. Commenting on ROCKWOOL’s own deep renovations, Jens Birgersson explained: “During<br />

2021, we made good progress on our energy efficiency in own offices goal, completing the renovation of an additional five buildings. One of these was our<br />

main office in Gladbeck, Germany, where we succeeded in reducing energy consumption by 83 per cent.”<br />

He continued: “What we are proving is that it is possible to renovate existing buildings up to the energy efficiency standards for new buildings.”<br />

Also in 2021, ROCKWOOL says it took significant steps toward reaching its science-based decarbonisation target to reduce its overall absolute<br />

greenhouse gas emissions by one-third by 2034. CEO Birgersson explained: “In 2021, we converted three production lines to low-carbon intensive<br />

melting technologies and fuel sources, as well as announced plans to build and convert additional low-carbon capacity. The emission-reducing effects of<br />

these and other investments will kick in over the coming years, helping us to achieve our decarbonisation ambitions.”<br />

SAP REVEALS IMPRESSIVE NUMBERS<br />

A third showhome created by timber-frame specialist Scandia-Hus and insulated with Actis<br />

Hybrid products has achieved an impressive suite of energy efficiency and environmental<br />

performance parameters ahead of its unveiling to the public in the spring.<br />

Its performance is captured in the as-built SAP calculation, which reveals an improvement of the<br />

The Mulberry is the third Scandia-Hus showhome to be<br />

Dwelling Emission Rate of 35% over the notional building specification and an improved Fabric Energy insulated with Actis Hybrid products. The as-built SAP<br />

Efficiency rate of 24.5%. The 2,755 sq ft three-bedroom chalet bungalow at Scandia-Hus’ Sussex calculation showed its Fabric Energy Efficiency rate is<br />

nearly 25% better than the target FEE.<br />

premises also achieved an energy efficiency rating of B. And it has an impressively low level of air<br />

permeability, achieving an air leakage rate of 3.25 m³/hm² at 50Pa, with this number of air changes per hour falling way within the building regulations'<br />

limiting or notional values of 10 and 5m³/hm² @50Pa respectively. The UK’s largest designer and supplier of Swedish energy-saving timber-framed<br />

homes was so impressed by the thermal efficiency achieved in the first two showhomes it built at its Sussex HQ that it replicated the precise<br />

specification it used on those buildings for its latest creation. The home offers the same U-values achieved in the initial two buildings - 0.14 in the roof<br />

and 0.16 in the walls thanks to the installation of vapour control layer HControl Hybrid and 155mm honeycomb design Hybris in the pitched roof and<br />

HControl Hybrid and 105mm Hybris in the walls. Scandia-Hus MD Derek Dawson said: “Using Actis reduced installation time by up to 30%. Previously,<br />

insulation was installed in two phases – the first in the factory and the second on site after the first fix was complete. Actis Hybris is easy to install. The<br />

panels are easy to cut to exactly the right size so they simply slot into the stud wall. Due to the use of service voids and the ease of installation, the<br />

insulation will now generally be installed in one phase on site. This also ensures that the air tightness of the building is not compromised by follow-up<br />

trades. Other benefits were minimal wastage and site cleanliness. And as if that is not benefit enough, the Hybrid range does not produce irritant and<br />

messy dust when installing.” www.insulation-actis.com<br />

Tool Focus<br />

THE LATEST TRENDS IN TOOLS<br />

Andy Mills, MD, FEIN UK, talks innovation and trends in tool development.<br />

The initial height of the pandemic and first<br />

lockdown completely halted the home<br />

improvement sector. However, as<br />

restrictions were eased and tradespeople and<br />

installers were allowed back into people’s homes<br />

to continue work, consumer spend on home<br />

renovations surged considerably. In fact, data<br />

from Houzz & Home confirmed spend on home<br />

renovations surged by 36% during the last year to<br />

a median of £15,000.<br />

But with a huge backlog of jobs still causing<br />

havoc across the industry two years on,<br />

combined with the supply chain crisis, efficient<br />

and reliable tools to ultimately improve<br />

productivity will be essential to successfully<br />

navigate an increasingly demanding market.<br />

As the inventor of the first electric hand held<br />

power tool, our strategy at FEIN has been rooted<br />

in innovation and efficiency for over 150 years.<br />

Our ethos is centred on providing solutions to the<br />

everyday challenges tradespeople face.<br />

The power tools of today have evolved<br />

considerably, encompassing so much more<br />

thanks to innovation in technology accelerating<br />

considerably in recent years. But, what are the<br />

biggest trends currently paving the way in the<br />

tools industry that tradespeople should have on<br />

their radar? And what innovations are shaping the<br />

future of this ever-evolving space?<br />

Efficient tools to improve productivity<br />

Declining productivity is having a huge impact on<br />

many sectors across the UK, something many<br />

tool manufacturers like FEIN have front of mind<br />

during the initial R&D (research and<br />

development) process.<br />

As such, we’ve seen a real surge in the use of<br />

oscillating multi-tools (OMTs) that enable<br />

tradespeople to complete a vast range of jobs<br />

with just one tool. FEIN’s cordless MultiMaster,<br />

“We’ve seen a real surge in the use of oscillating multi-tools”<br />

“Everything from<br />

increased capability<br />

and greater precision,<br />

to improved health and<br />

safety have really<br />

shaped the direction<br />

the industry has<br />

headed in”<br />

for instance, is compatible with around 180<br />

accessories from the Starlock, Starlock Plus and<br />

StarlockMax performance classes, meaning it’s<br />

quick, easy and convenient to switch applications<br />

without switching tools. The MultiMaster can be<br />

used for a number of tasks, increasing<br />

productivity and efficiency, in turn driving<br />

profitability.<br />

Embracing new technology to drive<br />

innovation<br />

Recent years have seen tools become noticeably<br />

more cutting-edge, thanks to advancements in<br />

technology. Everything from increased capability<br />

and greater precision, to improved health and<br />

safety have really shaped the direction the<br />

industry has headed in.<br />

There’s a lot of opportunity for tradespeople to<br />

embrace this new technology to ultimately help<br />

them to improve quality, efficiency and overall<br />

aesthetic of a job, thanks to such advancements.<br />

For instance, just a few years ago, several tools<br />

were required to complete a single job but thanks<br />

to a growing market of universal OMTs, many<br />

have been able to streamline their ways of<br />

working. The new technology available on the<br />

market is enabling tradespeople to successfully<br />

navigate current market challenges, while<br />

completing jobs in a timely manner and to the<br />

highest possible standard.<br />

Putting health and safety to the top of<br />

your agenda<br />

Just last month, the Health and Safety Executive<br />

revealed injuries and ill health to workers are<br />

costing the UK construction industry<br />

approximately £1.29bn a year.<br />

Traditionally, tools weren’t built for a full day on<br />

the job and in some instances have resulted in<br />

long-term health repercussions for installers.<br />

However, the health and safety of end users is<br />

something that’s always been firmly front of mind<br />

for us. Investing in the right tools and those with<br />

a built-in anti-vibration system will ensure<br />

continuous safe and pleasant working, thanks to<br />

minimal vibrations and outstanding noise<br />

insulation, while protecting from the long-term<br />

effects of hand arm vibration syndrome. It’s also<br />

important to take the time to read the<br />

manufacturer’s guidelines every time you<br />

purchase a new tool. This not only ensures you’re<br />

getting the most out of the tool and are able to<br />

capitalise on all features, but that you’re also<br />

operating it safely.<br />

EXCLUSIVE TOOL HIRE AGREEMENT<br />

Milwaukee and Speedy Hire have announced an exclusivity deal within the UK hire industry on the MX Fuel product<br />

range. The deal means that Milwaukee will only supply cordless low carbon MX equipment for hire in the UK to Speedy.<br />

In 2021 Speedy became the first hire provider in the UK to significantly invest in the battery powered MX Fuel Tower Light,<br />

described as a game changer for the industry, introducing high-performance, cordless lighting with zero emissions. Speedy<br />

says it will now invest across the low carbon MX Fuel product range including the demolition hammer, cut off saw and<br />

diamond core drill. Speedy will become the sole hire destination in the UK for this cutting-edge product range.<br />

Dale McElveen, General Manager, Milwaukee: explained: “Contractors require equipment that supports them in meeting client carbon emission targets as<br />

the industry moves towards net zero, while ensuring they deliver their projects safely, on budget and on time with no compromise on productivity. Our new<br />

MX Fuel range is designed to help businesses meet these priorities with a zero-emission operation, low running costs and reduced vibration exposure.<br />

With its UK-wide network of service centres and delivery networks, Speedy is now the exclusive hire destination for MX Fuel. We look forward to working<br />

even closer together to deliver more sustainable products for their customers.” www.speedyservices.com / www.milwaukeetool.com<br />

RHINO STEPS UP REAR SENSOR OPTIONS<br />

Rhino Products has launched its popular rear step parking sensor integration product, Connect+, for the<br />

Renault Master and Vauxhall Vivaro platforms.<br />

Rear vehicle steps are an important accessory for many van uses, providing a safe and secure platform to enter the vehicle,<br />

as well as access the roof. Reversing sensors for commercial vehicles have long been an expectation for many years now, however making alterations to<br />

introduce an external step with parking detection technology has previously been a time-consuming process, often requiring specialist knowledge, complicated<br />

rewiring and of course, added expenditure. Connect+ neatly solves this problem by integrating each OEM sensor into the step via a simple ‘plug and play’<br />

cable. The process could not be simpler; the existing (OEM) sensors are removed from the van before reconnecting these sensors directly into the Rhino<br />

Products step. The wiring loom is then reconnected into the vehicle, and blanking plugs are provided to fill the space where the OEM sensors were previously<br />

located. The van’s sensors then work as normal, with the added reassurance that the step at the rear of the vehicle is also protected when reversing. Having<br />

already proved to be a hugely popular solution for modern commercial vehicles, Connect+ is now available for Rhino’s AccessStep, TowStep and TowStep Duo<br />

range, for a new and much larger selection of Europe’s most popular LCV variants. Connect+ is now available for the Renault Master, Nissan NV400, Vauxhall<br />

Movano, as well as the Vauxhall Vivaro, Citroën Dispatch, Fiat Scudo, Peugeot Expert, and Toyota Proace. www.rhinoproducts.co.uk<br />

MAKITA EXPANDS XGT 40 MAX RANGE<br />

Makita UK has expanded its powerful XGT 40VMax range of machines with the launch of the new HS009G 235mm<br />

Circular Saw and ML006G Flashlight. It has also released the DX15 ‘on-tool’ Dust Collection System (191X40-4) that<br />

is compatible with its HR007GZ XGT Rotary Hammer.<br />

HS009G 235mm<br />

HS009G 235mm Circular Saw: The HS009G is a fantastic tool for anyone looking to reap the benefits of cordless, whilst<br />

Circular Saw<br />

still experiencing the power associated with corded models. Thanks to a large brushless motor and XGT battery technology, this machine can deliver the<br />

same – or higher – performance than that of corded alternatives. As such, the HS009G is ideal for higher demand applications. For precision cutting, the<br />

HS009G is compatible with the new 191141-8 guide rail and it can produce bevel cuts up to 1° left and 60° right, with positive stops at 22.5° and 45°. It<br />

offers a maximum cutting capacity of up to 61mm and a cutting speed of 4,00rpm, making light work of any cutting task. To improve user safety, the<br />

HS009G features Makita’s Auto Start Wireless System (AWS). When fitted with an optional AWS chip, the HS009G can be wirelessly connected to compatible<br />

dust extractors via Bluetooth and ensures that when the machine is in use, the extractor automatically turns on. ML006G LED Flashlight: This XGT 40VMax<br />

flashlight is the ideal site companion, featuring 18 extra bright LEDs that can deliver up to 500 lumens (depending on the setting chosen). The specially<br />

designed light diffusing lens softens the LED light to prevent glare and provide widespread illumination. What’s more, the ML006G offers an impressive 82<br />

hours of continuous illumination (when used in low mode) and the flashlight head can be easily adjusted to ensure the work area is always lit. DX15 ‘On-<br />

Tool’ Dust Collection System (191X40-4): Compatible with Makita’s XGT 40VMax HR007GZ Rotary Hammer, the DX15 makes dust collection a breeze. It<br />

can be used with drill bits up to 260mm and the depth gauge can be effortlessly adjusted. Thanks to the inclusion of a HEPA filter, the DX15 can capture<br />

even fine particles for maximum user safety – and the filter can be easily cleaned to ensure longevity. Kevin Brannigan, Marketing Manager at Makita said:<br />

“Makita’s XGT range has been designed to offer professional users a range of powerful machines that are ideally suited to higher demand applications. We<br />

are dedicated to providing the industry with an array of innovative solutions and have spent years refining our battery technology so that our products deliver<br />

the high output needed without compromising on battery run time, meaning professionals can work disruption free for longer.” www.makitauk.com<br />

AN UPLIFT IN SUSTAINABILITY<br />

Pitched roof tile manufacturer, Russell Roof Tiles, has continued its commitment to sustainability<br />

by investing in a fleet of electric forklift trucks (EFL).<br />

This follows extensive trials which proved the vehicles reduced emissions and provided a more efficient<br />

outlet for the electricity generated at its sites. The manufacturer says the decision to switch to electric<br />

was made after months of extensive market research and trialling of different electric forklift models to<br />

The new electric forklift trucks will arrive later this year.<br />

find an eco-friendly option that was easy to handle and efficient for the team. Linde Material Handling,<br />

one of the world’s largest manufacturers of forklift trucks, took first place with its new and improved X Range of electric forklifts, which Russell Roof<br />

Tiles says are now pre-ordered ready for the busy year ahead. Investing £900,000 into the Linde X Range electric forklift trucks is part of Russell Roof<br />

Tiles’ wider sustainability mission and falls in line with the latest announcement of their Net Zero 2040 pledge which they will implement over the next<br />

18 years. The company began their sustainability mission five years ago and will continue long into the future, with the switch to electric being one of<br />

the small changes to come this year. Bruce Laidlaw, Operations Director commented: “The switch to electric is key for us to continue reducing our<br />

emissions and forms part of our bigger picture to becoming Net Zero. After trialling the Linde electric forklift, we know it’s going to have a huge impact<br />

on reducing the local air pollution as they are completely emissions free. Our investment in the forklifts is another step towards our sustainability goal so<br />

we’re looking forward to receiving the new arrivals.”<br />

The latest upgrade on the Linde X trucks brings many benefits from the new Linde technology including the load stability system and class leading<br />

operator ergonomics. The new Linde forklifts will be used across all three sites to enhance performance and stop harmful CO ²<br />

levels being produced as<br />

well as achieving long-term high productivity levels. The battery-operated vehicles can perform beyond the limits of conventional electric trucks and can<br />

master steep gradients and operate within dusty and dirty environments. Chris Probert, Account Manager at Linde Material Handling (UK), commented:<br />

“We are pleased to be part of Russell Roof Tiles’ pledge to become Net Zero by 2040. The introduction of our new electric trucks will play a big part in<br />

reaching this goal. We look forward to working together for many years to come.” www.russellrooftiles.com<br />
