Topping out tile technology
The British Standard for Slating and Tiling BS5534 provides the industry with guidance on best practice, relating to the
installation of a roof. The revisions to the code of practice that took place last February 2015 for slating and tiling has ensured
that UK roofs are more secure in the face of increasing extreme weather conditions – it is clear that extreme weather events
such as gale force winds, driving rain and flooding are on the rise and placing more strain on the UK roofscape than ever before.
Whilst a large proportion of the
roofing market is taken up by new
build, there is a significant demand
for the refurbishment market.
Both social housing stock and commercial
buildings such as schools, colleges, hospitals
etc. require upgrading periodically to ensure
they are kept at an acceptable standard.
A stitch in time
Social landlords and commercial building
owners are acutely aware of the fact that a
structure that is looked after through regular
maintenance and refurbishment will provide
tangible financial savings in the future;
providing the correct materials and products
are specified in the first place. These preemptive
investments not only benefit the
residents or users of a property, who can
enjoy greater energy efficiency and
performance, but it will also greatly benefit the
landlord, who will experience a significantly
longer period of time where little to no major
maintenance on the building is required.
Tilcor Roofing Tiles
RCM Building Boards and Facades have
recently launched a premium range of
products suitable for the lightweight roofing
market including park homes, BISF houses,
social housing refurbishments and
conservatories.
Manufactured in New Zealand using materials
sourced only in the region allows Tilcor’s
products to be a leader in the industry and
across Europe. Their pressed roofing tile
systems incorporate the advantages of steel,
come with 50 year weather proof warranties
and deliver unique strength and resilience,
even in harsh climates.
Fabricated from Zincalume® protected steel,
Tilcor’s textured finish provides added
protection by embedding natural stone
granules (found only in New Zealand) in an
acrylic base-coat. This extremely durable UVresistant
coating enables Tilcor’s products to
withstand the harshest environments and
gives the tiles longevity and a service life over
that of traditional tiles.
The Tilcor range of pressed metal roofing tiles
includes eight distinctive profiles in a wide
range of colours.The profiles include a Classic
texture tile, popular because of its angular look
with sharp clean lines and sloping edges that
add dimension to a roof top. While the bond
design carries a more traditional British
appearance, with a characteristic scalloped
form. The unique shingled texture of the Royal
design adds dimensions and shadow lines to a
roof. Whereas, the Shake surfaced tile features
a wood-grain form and is created to enhance
the shadow lines and create a visual contrast.
The finish of the Tudor tile follows a more
traditional European appearance and is well
suited to both modern and traditional homes.
Ian Quinton, Managing Director of RCM said:
“As the changes to the standards primarily
affect roofing and building contractors, RCM
are fully aware of the standards required to
meet the UK’s challenging weather conditions.
Our new Tilcor roofing tile range consistently
delivers quality and product performance and
offers contractors a lightweight alternative to
slate and clay tiles.”
Sustainability is an important focus for Tilcor,
with all steel products being fully recyclable.
All offcuts and unused materials are collected
from site and recycled, improving the
environmental outlook for home owners and
contractors.
Tilcor is manufactured by the Ross Roof Group
who have been involved in the roofing
industry since 1942. A world leader in roofing,
their tiles are now installed in over 80
countries.
For manufacturers such as Tilcor, it is vital to
nurture relationships with social landlords and
commercial contractors to ensure that their
stock is upgraded efficiently and effectively –
providing savings and increasing comfort for
building users and landlords alike, year
after year.

Here at R&R it’s been an exciting
time – a change of ownership sees
the title move from Waverley
Communications to BuildInsite Ltd,
headed up by Kevin Edgeworth and
long-time R&R publication manager
Paul Barstow. Published quarterly,
we’ll be covering all aspects of
refurbishment and retrofitting, and
introducing new features that will
include our readers in our content.
Why not get in touch and tell us
what you’re working on?
And it’s a great time for a re-design
and re-launch, with UK
Construction Week just around the
corner! The nine shows that make
up this event will attract between
them virtually everyone who works
in the construction industry and its
supporting sectors.
And we’ve a packed issue to kick off
our new look!
Buildoffsite.com is a membership
organisation that acts as the voice of
the UK offsite construction industry,

As in designing and constructing new build construction it is still somewhat
unusual for the project team to give proper consideration to the practicalities of
future refurbishment and possible reconfiguration. In most cases this is probably
a short-sighted omission; Roisin Sweeney of Buildoffsite.com explains.
20 Ongo Homes decides on refurbishment rather than replacement
Social Housing provider Ongo Homes Scunthorpe has engaged Mila Window
and Door Maintenance to refurbish windows in three high rise tower blocks in
the town, and key supply chain partner Siegenia has provided the critical
hardware solutions.
27 WUFI ® calculation addresses moisture issues in UK housing stock
As the government strives to improve energy efficiency in the UK housing stock,
the solid walls upgrade can cause problems, which are not readily highlighted
within the existing Glaser method of condensation prediction. The current
housing stock in the UK of solid walls, and hard to treat walls, is causing a serious
issue on how best to address the thermal solution.
38 The best way to board your loft - StoreFloor
Utilising loft space and the methods of allowing safe access to this space can be

UK construction sector moves closer to stabilisation in August
UK construction companies indicated a sustained reduction in business activity during August, but the pace of decline was only marginal and
much softer than the seven-year record seen during July. New order volumes also moved closer to stabilisation, with the latest reduction the
least marked since May. This contributed to a renewed rise in staffing levels across the construction sector and a rebound in business
expectations for the next 12 months. However, latest data indicated a further steep acceleration in input cost inflation.
Purchasing prices rose at the fastest pace for just over five years amid reports that exchange rate depreciation had acted as a catalyst for
increased charges among suppliers of construction materials.
Reports from survey respondents suggested that Brexit uncertainty continued to act as a brake on the construction sector during August,
especially in terms of house building and commercial work. However, a number of firms noted that sales volumes had been more resilient than
expected. Some panel members also commented on signs of a rebound in client confidence from the lows seen earlier this summer. Reflecting
this, latest data highlighted that incoming new work decreased at the slowest pace since May.
£7.1m redevelopment of Essex sheltered
housing scheme
Uttlesford District Council has chosen partnership housing
specialist Lovell to undertake a £7.1 million redevelopment
programme for an Essex sheltered housing scheme.
The existing sheltered housing is being replaced with 41 brandnew
apartments for affordable rent – made up of 34 onebedroom
and seven two-bedroom homes – as well as new
communal facilities including a communal lounge and a garden
room, hair and beauty salon and a guest suite. The first phase of
demolition and site clearance has already been carried out. The
demolition programme is being undertaken in two stages
enabling existing tenants to stay at the sheltered housing scheme
while it is being rebuilt.
The new complex is designed to achieve a ‘Very Good’ rating
when assessed using the BREEAM system for measuring
buildings’ sustainability. Energy-saving and environmentallyfriendly
features include underfloor heating and a sedum green
‘living roof’ which reduces rainwater runoff and provides a
habitat for wildlife.
Houses of Parliament refurbishment could
cost well over £4bn
Completed in the 1860s, the Palace of Westminster is in dire need of a
retrofit.
It appears that since 1992, services such as heating, cooling, water,
sewage, electricity and cabling have been kept semi-functioning, but
have not been modernised. Astoundingly, there has been no real
general renovation of the building and its services since the partial
rebuild of 1945-50 – some of the services even predate the war.
Reports illustrate that asbestos features heavily throughout the
palace, which makes any intervention so much more difficult.
The building is completely at the mercy of fire, with little modern
safety practices in place and fire compartmentation considered
almost impossible.
The original roofs are no longer watertight and there are many areas
plagued with penetrating damp, damaged by interior leaks and
flooding.
The sheer amount of work and the sensitive nature of refurbishing a
World Heritage Site results in a sky-high estimate of between £3.5bn
and £5.7bn, with some suggesting the sum could rise to as much as
£7.1bn.
HS2 CEO Simon Kirby steps down from role
The CEO of HS2 project, Simon Kirby is leaving HS2 for a new job with Rolls-Royce as chief operating officer.
On joining HS2 Ltd, Kirby became the highest paid civil servant in the country, earning £750,000, five times the salary of the Prime Minister. He
justified this saying he could get the project in on time and budget, but since then both the budget and the timescales have gone the wrong
way.
Simon Kirby says he has not lost confidence in the project, commenting: “HS2 is not just a highly ambitious project, but also one which will leave
a lasting legacy for Britain. It has been, therefore, a huge honour to have been its Chief Executive and to have been involved in creating a
leadership team made up of the best talents from this country and elsewhere. I have absolute confidence in their ability to deliver the project
and, in doing so, to help transform the way we do things in this country.”

New research shows how used tyres can help protect bridges
In UK alone, 50 million tyres are discarded each year. With an ever increasing volume of vehicles in the world, the disposal of spent tyres is a
serious issue.
New research published in the Journal Earthquake Engineering and Structural Dynamics has described a new method of protecting bridge
infrastructure in disaster-prone regions using used tyres that may otherwise be sent to landfill.
The challenge for the researchers was to find an inexpensive and effective material to bolster bridges, providing support but also providing a
buffer able to withstand the force of earthquake situations regardless of the length of the bridge. The team turned to conventional tyres; waste
tyres will be used to create a new product, called the isolator, namely a flexible and elastic layer of reused tyres. This flexible layer will be used to
absorb movements, reducing costs of repair.
The new design will eventually allow for safer and sturdier bridges in areas that do not have the means to erect expensive structures that require
extensive maintenance.
Parliament calls for greater sustainability in
transport infrastructure
Parliament’s Environmental Audit Committee has published a report
calling for greater sustainability from the Department for Transport in
future infrastructure projects.
The Department’s total spending is set to increase during this
Parliament: although its resource spending is due to go down, its
capital budgets will rise, with £73.4 billion of transport-related capital
investment between 2015–16 and 2020–21, including £34.5 billion for
Network Rail and £15.2 billion for its Roads Investment Strategy. In
2014–15 the Department allocated 50% of its gross expenditure to its
roads, traffic and local responsibilities; almost 40% to its rail executive
responsibilities; and 3% to its international, security and environment
responsibilities.
Whilst Parliament acknowledge that many positive steps have been
made towards better sustainability within the transport sector, the
report focuses on those areas where the Department for Transport
might go further to tackle climate change.
This has been welcomed by Campaign for Better Transport who will
be writing to the Department demanding further reduction of their
carbon footprint.
The regeneration of London’s 2012
Olympic Stadium
Balfour Beatty, working with Populous, Buro Happold and the
London Legacy Development Corporation, have repurposed the
iconic London 2012 stadium.
The stadium, which is now home to West Ham United FC, will have
a capacity of 54,000 people for football matches and 80,000 for
athletics events and music concerts.
Sustainability and skills building
Sustainability has been at the very heart of the redesign. So far the
work undertaken has included the reuse of 19,000 tonnes of
recycled demolition materials, 6,000 m of cable, 3,800 lights and
1,000 mechanical and electrical components. This sends a message
to the refurb and retrofit industry of what can be done to reduce
the volume of waste to landfill. (According to a report by the Wates
Group, the UK construction industry sends 36 million tons of waste
to landfill sites each year.)
The regeneration project has also been doing its bit to tackle the
skills shortage, with Balfour Beatty creating 50 local apprenticeships
and over 300 training opportunities across the site.
Reducing carbon usage in the built environment
The University of Wolverhampton has secured £1.2 million in additional funding to help small businesses develop low carbon products which
can be used by the Built Environment and Construction sector.
The Built Environment Climate Change Innovations (BECCI) project is part funded by the European Regional Development Fund and works with
small and medium businesses across the Black Country and the Marches region to develop innovative climate change solutions within the built
environment. Its broad coverage is on products associated with both new and existing housing as well as commercial and public buildings.
Paul Hampton, Director of the BECCI project and Head of Built Environment at the University of Wolverhampton, said: “The University is
delighted to support the team on the whg energy challenge. This is just one example of how we are utilising funding to cut carbon emissions in
line with the government’s commitment to reduce the carbon footprint by 80% over the next thirty years.”

British summertime bolsters
demand for decking profiles
Leading plastic extruder for
multiple industries,
Euroseal, has reported a
surge in demand for deck
boards, as the summer
season has prompted a
record number of
renovation and home
improvement projects.
Euroseal manufactures a
comprehensive range of products for the building and
construction market, supplying businesses of all shapes and
sizes.
“Projects of this kind often require the reconstruction of the patio
area, and that’s had a significant contribution in our volume
increase for decking solutions,” said Euroseal managing director,
Chris Byers. “Garden redesigning and landscaping projects are
also soaring, as a busier lifestyle for the end-user means there is
less time to look after the outdoor space, and a low maintenance
solution is required, with decking being an obvious choice.”
According to the manufacturer, advances in plastic extrusion,
alongside the company’s own sustained investment in new
equipment, have also contributed to the surge in demand.

Thinking outside of the box
The building envelope, whilst being an essential weatherproofing element of any structure, is permanently on display, so
requires as much design consideration as technical specification. We look at three projects which get this just right.
ESRI, Swansea
Leading external envelope contractor
Prater has delivered an exemplary
building envelope for the £30m
refurbishment of Ark Putney Academy, a
secondary school in Putney, West London.
The project overall has resulted in the
creation of a 21st century learning
environment whilst sensitively preserving the
heritage of its existing Grade II listed main
school building..
The ground-breaking London County
Council’s department of architecture, also
responsible for the iconic Royal Festival Hall,
originally designed the school, formerly
known as Elliott School, in the fifties. However,
time had taken its toll and the buildings were
in need of essential repairs and modernisation,
showing signs of substandard classrooms,
dilapidated cladding and year-round problems
with heating, cooling and ventilation.
Internationally-renowned award winning
practice Hawkins\Brown has worked with
Lendlease and the London Borough of
Wandsworth to re-furbish, re-model and reimagine
the school, now known as Ark Putney
Academy. Prater was appointed for its
technical expertise and operational capabilities
to deliver, demonstrating the best solution for
this challenging project.
There were several elements to Prater’s
involvement. Firstly and completely reinventing
the look of the building, Prater
installed a new environmentally responsive
façade comprising 4000m 2 new Schuco
curtain walling to the main five-storey building
with better insulated, modern glazing to
improve year-round temperature and energy
management, also creating lighter, brighter
classrooms. Also 1000m2 SFS, Steni Colour
Rainscreen was installed to the new sports
hall.
One of the key challenges was the delivery of
the replacement glazing to the 'Zig Zag'
staircores to the main building.
“Curtain wall elements were integrated into
the main façade with curtain wall screens
connected back to the Grade II listed floating
staircase landings – it was a real challenge but
looks great,” explained Prater project manager,
Mike O’Boyle.
Prater was also responsible for the roofing
work. Replacing the demolished gym block is
a new, purpose-built four-court community
sports facility, constructed to the latest Sport
England standards. Prater worked alongside
supply chain partner Bemo, to install the
800m2 acoustic (attenuation and absorption)
standing seam roofing system to the new,
barrelled sports hall roof.
Furthermore, 900m 2 Sika Sarnafil single ply
roofing was installed to the DT block, sports
hall link and canopies.
In Swansea, architectural glazing systems from
Kawneer have helped an exemplar building in
sustainable, low-energy design become the
first education building in the UK to achieve
BREEAM Outstanding.
The £12.65m Energy Safety Research Institute
(ESRI) was the final project to be delivered
through the 2009-2014 capital projects
framework at Swansea University and is a
unique centre of research innovation,
facilitating ground-breaking work into the safe
deployment of new renewable energy
solutions.
The Kawneer systems were used throughout
the 4,500m 2 building and comprise AA®541

BP, one of the university’s major industrial
partners. Its funding through Central
Government’s UK Research Partnership
Investment Fund was contingent on achieving
a BREEAM Outstanding rating which made it
the first education building to do so.
One of its key innovations is a layout that
inhibits any form of silo culture within the
research areas by placing a strong emphasis
on the shared space between research groups.
Building users and visitors are able to see into
the laboratory spaces from the circulation
areas and gain a feel for the activities going on
inside.
The state-of-the-art Harvard-style lecture
theatre is a fully-serviced space for public
events as well as research-based activities.
Beyond the entrance foyer a linear form
dictates the layout of the rest of the ground
floor, comprising three main chemical
laboratories and serviced ancillary space
together with the main marine laboratory. This
facility is unique in Wales, featuring a
technically-challenging 30m-long wave flume
tank which allows the university to model
estuarine tidal flows and silt deposition.

Building Envelope specialist, CA Group
Limited, has successfully installed its Prime V
Rainscreen on the ‘Gateway Project’, a stateof-the-art
building set to transform the
entrance to the University of Salford.
The company manufactured and supplied its
secret fix rainscreen, which has been
incorporated into the soffit of the entrance.
This is the first time that this particular
rainscreen solution has been used in an
application of this kind.
Prime V Rainscreen, which is based on a
cassette panel mechanism that interlocks at
the uppermost edge to conceal the fixings,
was selected due to its aesthetic qualities that
met the architect’s specification of a fix-free
finish.
“The project team worked closely to come up
with a suitable design which was both fit for
purpose and provided the high quality,
seamless finish that the client was looking to
achieve,” explained Chris Priestley, Rainscreen
Systems Manager at CA Group. “Prime V allows
the designer the flexibility to create traditional
or unconventional aesthetics using a broad
range of metals, colours and finishes,
supported by a coating guarantee on the
painted finishes.”
The main contractor on this project was

Warming to sustainability
Older housing stock frequently has inadequate or non-existent insulation and few energy efficient appliances. We speak with
Brody Isaac, the Sustainability Manager for Viridian Housing, about his organisation’s approach to improving housing standards.
“If ventilation is not
considered when
improving the thermal and
airtight efficiency of a
property, damp and mould
growth are nearly certain
to crop up in a later year, if
not immediately.“
Brody Isaac
R&R: What projects have you recently been
involved with that included retrofitting
energy efficiency products and services?
Brody: Viridian has been involved with several
energy efficiency programmes from draft
proofing to external wall insulation, all with the
aim of improving the housing standard of our
properties.
Since the autumn of 2015, we have carried out
cavity insulation in 383 homes which had
been built in the 1990s and only had partial
cavity fill. This work was funded via ECO.
Over the past year we have carried out draft
proofing and secondary glazing in over 150 of
our properties to improve their thermal
performance, and to give our residents some
added comfort.
We have also recently procured an external
wall insulation (EWI), cavity wall and loft
insulation contract. With this, we aim to focus
on our lowest energy performing properties.
This will include providing EWI to 300 homes
as well as 1000 cavity wall installations and
1000 loft insulations jobs.
R&R: What are the types of
products/services you usually install?
Brody: Our product of choice for cavity
insulation is a blown bead insulation system.
The external wall insulation uses EPS
expanded polyester boards. Our secondary
glazing is produced by a bespoke system,
which uses magnets and polycarbonate
plastic. The process creates value for money
by driving down costs.
R&R: How were these projects funded?
Brody: Our cavity wall insulation contract,
worth approximately £250k, was funded via
ECO.
The EWI, cavity wall and loft insulation
contract has been funded completely by
Viridian as part of our commitment to
improving our homes and the lives of our
customers.
R&R: What funding/encouragement would
you like to see made available to encourage
RSLs/householders to improve energy
efficiency to save money (and resources)?
Brody: Housing associations should be
allowed to increase rental income on homes
where retrofit works have been undertaken;
we would like to partially fund these over a 10-
year period, based on a proportion of the
energy savings.
Also, corner junctions and edges are tricky
aspects with EWI but there’s not enough detail
about this in the design guidance. Having
tighter design guidance in the new PAS2030
specification will help highlight the calculated
savings in both pounds and carbon. Making
these changes will tackle below-standard work
by ensuring only the best quality of work is
approved and best practice is adopted.
Funding mechanisms, such as ECO, are
currently focused on the quantity rather than
the quality of the work. This can mean that
poor quality jobs are approved and, as a result,
it puts the industry off the idea of retrofit
because it’s seen as a high technical risk. If the
quality of the overall work was improved,
confidence would be improved. As the
majority of the UK’s worst performing
residential properties are solid wall and F & G
SAP rated, solid wall insulation certainly needs
to be more attractive.
The main constraints to low energy retrofit
projects, like many others, are time and
money. Where funding has been made
available it usually dictates the time frames
and how much money can be spent per
property. This has multiple knock-on negative
effects. For example, choosing a cheaper and
quicker option can cause problems in the
years to come. A key example of this is
ventilation with solid wall insulation for both
EWI and external wall insulation.
If ventilation is not considered when
improving the thermal and airtight efficiency
of a property, damp and mould growth are
nearly certain to crop up in a later year, if not
immediately. This has negative impacts for the
tenant in the property, decreasing their
standard of living and putting their health at

Smoke ventilation maintenance –
the hot issue for HAs and LAs
By Simon North – Service and Maintenance Division
Manager with SE Controls
Ongoing budgetary pressures
and a lack of familiarity by
local authorities and
housing associations about the strict
regulations that govern the
maintenance of smoke ventilation
systems, has given rise to a worrying
trend that will leave them exposed to
prosecution for non-compliance
unless it is addressed.
In an effort to integrate fire systems maintenance and save money
in the process, many HAs and LAs are ‘bundling’ smoke ventilation
maintenance into a multi-disciplined ‘fire service’ contract, where
the contractor is responsible for all fire and smoke system
maintenance, often across several locations and building types.
However, under the scope of various British Standards, including
BS9991, BS9999 and BS7346 Part 8, together with Building
Regulations ADB; the European EN12101 standard and best
practice guidance documents from the Smoke Control
Association, there are specific maintenance requirements and
procedures that must be followed.
The real ‘teeth’ behind this complex and vital legislative framework
is the Regulatory Reform Order (RRO). This gives fire service
officers an extensive range of enforcement powers in situations
where smoke control systems have been inadequately maintained
under the demands of the various pieces of legislation.
The penalties for non-compliance can be significant, including the
prosecution of companies, building owners, landlords and
individuals responsible for building maintenance, resulting in
punitive fines as well as custodial sentences.
At SE Controls, we
have already been
directly involved in
a significant
number of
projects to correct
problems caused
where general fire
contractors have
found themselves
out of their depth
and unable to maintain the smoke control system within the
demands of the regulations.
In one instance the maintenance company had failed to notice a
smoke vent that had been ‘nailed shut’ rendering it in operable
and dangerous, while another recent case of poor maintenance
from an inexperienced contractor resulted in an automatic smoke
vent falling out of the building. A major internal review followed,
together with the involvement of the HSE and prosecutions are
now being considered.
On a number of other remedial projects, fire officers or building
control have already imposed close notices on the buildings,
resulting in disruption, the removal of tenants and large
unbudgeted costs for the housing association. Clearly, these could
have been avoided if the specialised smoke ventilation
maintenance contract was kept separate and handled by a
specialist company, such as SE Controls.

Park Road Flats before EWI
These flats, owned by West Lothian
Council, were transformed with
Alumasc’s external wall insulation
systems Swisslab and Swistherm
Park Road Flats after EWI
risk. For the landlord, remediation works for
damp and mould growth can cost as much as
installing the insulation in the first place.
Another area that is negatively impacted
through reduced time and cost of the project
is thermal bridging. In nearly all the EWI
projects that I have seen, insulation is put in
around gas boxes and internet boxes. This is
instead of taking the boxes off, putting the
insulation on and then reinstating the boxes.
This looks unsightly and also produces a
thermal bridge for heat to escape through the
building, potentially causing condensation
issues on the internal wall. Getting RSLs to sign
up to their own low energy retrofit
programme alleviates time issues and costs
can be brought down through the economies
of scale.
To get Viridian Housing Association’s board to
agree to our own retrofit programme, we
asked them to consider three factors:
1) Fuel poverty - the risk to our tenants of
being in a low-energy home. It can affect
their finances and also their health.
2) The Housing, Health and Safety Rating
system classes the ‘extreme cold’ posed by
band F & G properties as a Category 1
Hazard. To be classed as ‘decent’ under the
Decent Homes standard, a dwelling should
be free of Category 1 hazards 1 .
3) The Minimum Energy Performance
Standard legislation has set a bench mark
which RSLs have a moral responsibility to
uphold to their customers and the
community.

Planning for future adaptation
As in designing and constructing new build construction it is still somewhat unusual for the project team to give proper
consideration to the practicalities of future refurbishment and possible reconfiguration. In most cases this is probably a shortsighted
omission; Roisin Sweeney of Buildoffsite.com explains.
Woodview Mews, built version of the LivinHome housing
system (courtesy of Geraghty Taylor Architects)
During the life of the building or
structure it is entirely likely that work
will need to be carried out to repair
and replace services, to refurbish and possibly
to carry out a complete reconfiguration
because the building is no longer required for
its original use or possibly because
replacement technology needs to be
incorporated.
OK, there will always be ways to carry out the
necessary work but this will inevitably be at an
unpredictable cost and will likely be carried
out over an extended period of time, when
with up-front planning there could be a faster,
more cost-effective approach.
This opportunity to fast track is increasingly
attractive to retailers who understand that it is
both necessary to carry out regular
refurbishment to ensure that the internal
environment is attractive to customers, keeps
up with corporate branding and that
associated services - whether these be
restaurants, changing facilities or back office
installations - are attractive and efficient. The
imperative for retailers will be to have the
required works carried out as quickly as
possible to their required standards. Extended
periods of closure are highly undesirable if
customer loyalty and revenue is to be retained.
A number of the most enlightened retail
clients are now working with Buildoffsite
through a specially constituted Refurbishment
Hub, to explore ways in which a fast-track
approach to projects will provide for rapid
dismantling and removal of existing
installations, and the installation of offsite
constructed replacement modules and
components. Ensuring that the original design
and service layout has had regard to the needs
of refurbishment will ensure that limiting
factors, such as the width of access points to
perhaps allow for the skid mounted delivery,
and installation of full size units, has been
taken into account. This is not rocket science
and there are plenty of examples of the
approach in, for example, the exhibition,
theatre/film and logistic sectors.
Much the same set of considerations will apply
to other building types where it is understood
that there will be a need for predictable and
efficient refurbishment. Hotel bedrooms,
restaurants and public areas are obvious
candidates for a planned fast track approach.
However, similar challenges exist for, say,
schools and hospitals and health facilities. In
these cases the need for refurbishment is
driven by changes in technology and in
practice. In health, the rate of advance in
clinical practice is so rapid that something of a
revolution in enabling technology takes place
every five years or so. Let’s just consider what
this means in terms of the need to carry out
major refurbishment to all those new facilities
that have been provided over recent years at
such huge cost to the public purse. The rate of
change in educational practice is not so fast –
nor possibly so disruptive – but it is still a
relevant consideration.
It is also a distinct possibility that opportunities
will arise for fast track refurbishment in the
housing sector. The concept of lifetime homes
requires an approach to design and
construction that allows for internal space to
be reconfigured, possibly for additional
modules to be installed and in due course
removed, and also the opportunity for in-situ
downsizing and upsizing.
If we don’t think about this alternative
approach then the inevitable consequence will
be reliance on demolition, waste disposal and
traditional forms of construction. All of which
will involve excessive cost, excessive
construction time and probably lower levels of
quality.
If you are interested in the opportunities
provided by the adoption of a fast track
approach to refurbishment then follow the
work off the Buildoffsite Refurbishment
Hub at their website.

Get spaced out with Garador
Sectional Doors!
In modern buildings, space is always at a premium inside and out,
and driveways are noticeably shorter today. So it is no surprise
that Garador’s sectional garage doors are now a top seller across
the UK.
These superbly engineered doors open vertically then horizontally
on tracks back into the garage, eliminating the problem of losing
driveway space through standard up and over doors which ‘kick
out’ on opening. Cars can park close up to the garage door, a huge
benefit in modern homes. There is also no loss of width in the
garage, giving maximum parking space for wider vehicles such as
4 x 4s and MPVs.
Along with their great practicality, many choose Garador’s
sectional garage doors to enhance the look and style of a
property. The doors come in a wide variety of surface finishes,
designs and colours, including ribbed and panelled versions,
elegant Georgian style and even ultra modern large linear, plus a
full range of size options, including standard and purpose made.
So there really is a door for every requirement and every build.

Ongo Homes decides on refurbishment
rather than replacement
Social Housing provider Ongo Homes Scunthorpe has engaged Mila Window and Door Maintenance to refurbish windows in
three high rise tower blocks in the town, and key supply chain partner Siegenia has provided the critical hardware solutions.
The three blocks were originally built in
the 1960’s and underwent a full window
replacement and external wall
insulation programme 20 years ago as a part
of refurbishment works during the 1990’s.
Head of Regeneration at Ongo, Neil Webster
explained their decision to undertake further
works on the site and why they went for
refurbishment of the windows rather than
another full window replacement scheme.
“We had become aware of the increasing
number of maintenance call outs to the blocks
with regards to windows in recent years and
had particular difficulty finding replacement
hardware parts. With the windows having
been installed for over 20 years many of the
parts had become obsolete as technical
advancements in the window industry
developed”.
“We were already planning to do work to the
lifts, heating system and communal areas on
the blocks so it was a good opportunity to
investigate the options for the windows at the
same time”.
“We were aware of a very similar scheme
which had been undertaken in pretty much
the same circumstances at Gentoo in
Sunderland and so we visited their site to see
what had been done and to see the positive
impacts on their blocks and on their residents”.
“The cost of replacing the windows for a
second time would have been prohibitive,
added to which was the potential damage to
the external insulation system, disturbance to
residents and the negative environmental
impact”.
“Our residents are always supportive of what
we try to do and understand that we try to
offer them the best solutions; after meeting
with Mila Window and Door Maintenance and
talking to our residents, and following a full
assessment of all the options available to us it
was clear that a ‘refurbishment scheme’ rather
than another replacement of the windows was
a viable and very attractive proposition”.
Tristan Cooke Managing Director of Mila
Window and Door Maintenance takes up the
story. “As Neil said, we spent a lot of time with
Ongo and their contractor considering all of
the options, and working out how we could
deliver them an answer to all of the issues
which needed to be addressed”.
“The biggest single issue for us to address, and
one of the key drivers Neil outlined earlier, was
identifying Tilt and Turn hardware which we
could fit the existing frames and sashes which
were originally installed. Over a period of
years, the hardware had been failing and in a
high rise living environment the risks are
significant”.
“This is where we were able to introduce one
of our key supply chain partners into the
equation. We have been working with
Siegenia for nearly 30 years and for Tilt and
Turn replacement hardware in high rise
applications they are able to provide the
perfect solutions”.
“A very rigorous assessment of the existing
frames and sashes alongside trials of our
proposed hardware options enabled us to
confirm to Ongo that we did indeed have an
entirely workable solution”.
John Chambers National Sales Manager for
Siegenia reinforced the same point. “Over 30
years the relationship between ourselves and
Mila Window and Door Maintenance has really
developed and we have not yet failed to find a
technically robust supply chain solution when
they have approached us to do so, and this
was no different”.
“As social landlords increasingly look to
refurbish and renew windows in situations
where external wall insulation has
subsequently been installed we know there
will be more and more of these situations
arising”.
“Hardware as we know should always be
maintained, even from new, but with the best
will in the world after 20 years it really should
be replaced in its entirety – earlier if possible.
Continuing to install the odd replacement part
is not sustainable in real terms as very quickly
a block can become a patchwork of different
hardware types”.
“It is great that Ongo had the foresight to take
the view they have and replace all the
hardware with a complete new set and that
they have engaged a specialist maintenance
contractor to do the job for them. This way
the new gearing is fully guaranteed as a new
installation thereby extending the life the
landlord’s assets”.
Neil Webster “Going down the refurbishment
route rather than replacing the windows is
clearly a fantastic outcome for Ongo and its
residents; the feedback about the completed
works and in respect of Mila Window and
Door Maintenance’s ability to carry out the job
has been excellent”.

I Predict a Quiet: SIG insulation’s team provides
acoustic solution for Kaiser Chiefs’ studio
Aunique project for the rehearsal space
of rock band Kaiser Chiefs has seen
SIG Insulation’s technical experts
provide an acoustic solution for the
refurbishment of the music studio in Leeds.
The SIG360 team, a specialist offering by SIG
providing energy efficiency guidance on new
and retrofit projects, was tasked with
improving sound attenuation between the
rooms of the Old Chapel, a music studio
which is also used to hold a number of
workshops for people with learning disabilities.
Having heard about the community work held
at the Old Chapel and its renovation plans
from British Gypsum, SIG Insulation’s Leeds
branch offered its products and services to the
project. Working with the Old Chapel’s
Director, Mark Hubbard, the insulation experts
assisted in the refurbishment of five studios, a
classroom for the workshops and office space
on the floor above.
To ensure the most appropriate products were
used, SIG Insulation brought the SIG360 team
on to the project, as well as acoustic
consultants KR Associates, who carried out a
series of tests including 3D modelling,
background noise surveys, and airborne and
reverberation testing.
The results of the testing enabled SIG360 to
specify the most suitable products for the new
studio, including SuperPhon wall panels and
Regupol acoustic underlays from acoustic
experts CMS Danskin, as well as acoustic
insulation and flooring products, all supplied
by SIG Insulation.
The refurbishment was also supported with
products provided by British Gypsum. The
high ceilings and exposed brickwork of the
building, which was formerly a church, meant
specialist systems were required to improve its
acoustic performance.
As well as isolating noise within the individual
studios, one of the main criteria of the
refurbishment was to maximise the sound
quality for the musicians, while also
controlling reverberation for the comfort of
the occupants in the office above.
To improve the level of sound insulation
within separate spaces, British Gypsum’s
SoundBloc – which boasts a reinforced core
and greater density when compared with
standard plasterboard – was specified for the
walls. For the ceilings, Eurocoustic ceiling tiles
were chosen for their Class A sound
absorption classification, the highest possible
grading. This ensured reverberation was kept
to a minimum.
Speaking on the project, Steven Marshall,
Business Development Manager at SIG360
said: “This was an unusual project that
required us to not only meet the acoustic
requirements of Approved Document Part E of
the Building Regulations, but to also go above
and beyond.
“While the focus was mainly on acoustic
performance, we also specified an acoustic
ventilation system to allow a constant flow of
fresh air, and well-sealed windows to provide
daylight while preventing the transmission of
excess sound whilst the band is practicing.”
Paul Mackler, Area Sales Manager for British
Gypsum, commented: “Achieving high quality
sound insulation within older buildings can be
particularly challenging, and requires specialist
products for the specific needs of the site.
“By using SoundBloc and Eurocoustic ceiling
tiles, we were able to ensure the finished
space offered the best environment for both
the musicians recording and the office
workers.”
The Kaiser Chiefs’ drummer, Vijay Mistry
described the new studio as a professional
space, rivalling some of London’s top studios.
“We have positioned
some of the acoustic
panels behind the kick
drum and the
improvement in sound
is brilliant.”
- Vijay Mistry,
The Kaiser Chiefs
He added “We have positioned some of the
acoustic panels behind the kick drum and the
improvement in sound is brilliant. We also
positioned more panels behind the amps to
steer the sound back into the room.”
Mark Hubbard, Director of the Old Chapel said
“We do a lot of work with people with learning
disabilities at the Old Chapel, and the
improved facilities have already made it much
more comfortable and usable, allowing us to
take on more work with young people in the
future, and make it accessible for schools.
“Most of the problems we originally had were
caused by noise travelling between studios,
however with these acoustic improvements,
we will now be able to have singing lessons in
one room and a rock band practicing in the
next.”

good selection of cut bricks in standard UK sizes ranging from 20-25 mm thick. Pistol
corner bricks are also available. These traditional looking bricks provide warmth and
character with Old English being the most popular selling brick in the Classic Range,
particularly for interior projects. The recent addition of EBS Newbridge Mix and EBS Old
Beaufort to the Range has also generated a lot of interest.
Managing director of Eurobrick, John Mayes, explained the success of the brick slips:
“We are one of the largest stockists of brick slips in the UK and have a wide selection of colours and finishes available at any one time. We try to
maintain a certain level of stock so customers can often have their bricks within two or three days of ordering. Even if stock levels of a particular
brick are low, we aim to replenish our supplies regularly to help reduce lead times for customers.
“Our customers really like the choice we offer and we have a showroom where all of our brick samples are displayed. For anyone thinking of
buying brick slips, with or without our cladding systems, we would encourage them to give us a call or visit our showroom to discuss their
requirements.”
Manufactured to order, Eurobrick also offers Bradstone reconstructed stone slips in a variety of sizes and colours. These slips can be used on their
own or combined with brick slips or other finishes for architectural detailing. Corner slips are also available.

Sika provides a rapid decking solution at
Potteries car park
At the intu Potteries shopping centre in Stoke-on-Trent, the
asphalt deck on the annex level of the car park was showing
signs of ageing and weathering. With removal and
replacement costly and time-consuming, Sikafloor®-32 Pronto deck
system from Sika was laid directly onto the existing asphalt to create
a watertight, non-slip deck whilst minimising waste and returning
the car park to full use within the shortest time possible.
With an annual footfall of over 12 million shoppers, intu Potteries is
the largest shopping centre in Staffordshire and South Cheshire and
one of the UK’s top 35 retail destinations. As part of a £20 million
regeneration project by Intu Properties and main contractor Wates
Construction, the site has been extended and remodelled to include
seven restaurants and a nine screen cinema – attracting thousands
more visitors and car park users every week.
Following a successful trial to demonstrate its bond to the substrate,
approximately 2,000m2 of Sikafloor®-32 Pronto was applied over the
existing asphalt to provide a slip resistant and hard wearing
waterproof surface. Utilising the fast setting properties of Sikafloor®-
32 Pronto decking system also ensured works could be completed
quickly, with minimal disruption and eliminating the need for material
to go to landfill. Offering excellent mechanical and chemical
resistance, Sikafloor®-32 Pronto has been fully tested to meet the
highest crack bridging standards available on the market – including
Marmox Thermoblock specified for low energy
extension to Kent school
The construction of a new extension
to the teaching facilities at Glebe
School in West Wickham, Kent, has
featured the use of 140 mm wide
Thermoblock units manufactured by
Marmox Limited, specified to carry the main
structural envelope of the two-storey
building. The incorporation of
Thermoblocks at the wall-floor junction
results in the virtual elimination of the heat
loss at this cold bridge. The new building
will provide the secondary school with a
number of facilities including an art-room,
additional classrooms and new washrooms.
Furthermore, as is common now in the
education sector, the extension has been
designed to achieve very good standards of
energy consumption through high levels of
insulation.
Marmox Thermoblocks are ideally suited to
this ‘Fabric First’ approach and are regularly
used to address the problem of perimeter
heat loss at both ground and upper floor
levels in either timber frame or more
traditional masonry construction.
Romford based Lakehouse was the main
contractor for the work and the 270
Thermoblock units – each measuring 140 x
600 x 65 mm – were supplied through
Jewson Builders Merchant. In addition, the
branch supplied tubes of Marmox Multibond
adhesive, which were used for jointing the
interlocking Thermoblocks. Thermoblock,
which has a compressive strength of
9N/mm2 was specified for this demanding
application of footing the supporting walls.
Thermoblock then serves to greatly extend
the heat flow path for the critical floor/wall
junction throughout the life of the building.
The 600 mm long units incorporate mini
columns of high strength concrete to support
the load of the wall above, while the low
lambda value insulation effectively lengthens
the path for cold-bridging. They are laid just
using ordinary bricklayer’s mortar and then
by sealing the interlocking ends together with
Marmox Multibond, they create a permanent
waterproof seal onto which the block or brick
wall is then build on.
BS EN1062-7 Method B, which tests the complete system through
20,000 crack cycles up to 0.5mm @ -20 oc. This demonstrates the
system’s ability to protect against water penetrating through the
membrane and ensures the future integrity of the deck.
With a comprehensive range of car park decking and full concrete
repairs systems, Sika provides a variety of solutions designed to meet
the harsh conditions that car parks are subject to, and provide
durability, cost effectiveness and an excellent finish. Following the
successful renovation of the intu Potteries annex roof top car park
area, Sika and their specialist contracting partner, have delivered a
bright, aesthetically appealing and safe car parking area.

Russell Roof Tiles celebrate 30 years
Leading manufacturer
Russell Roof Tiles has
marked 30 years of the
founding of its name with
specially made
celebration cakes –
enough for its 170 staff on
all three sites.
Originally founded as the
Annandale Tile Company
in Scotland in 1965 the name was changed in 1986 when the
company was purchased by Scottish Aggregate firm the Alexander
Russell Group plc and the name “Russell” replaced Annadale thus
creating Russell Roof Tiles.
To mark the anniversary three house shaped birthday cakes were
created, for their sites in Lochmaben and two in Burton, where they
were enjoyed by all staff.
After a dynamic history Russell Roof Tiles to this day retains a family
ethos, dedicating to investing in the staff to enable the business to
flourish. It was therefore essential that there was enough cake for
everyone to enjoy.
Andrew Hayward, Managing Director of Russell Roof Tiles, comments:
“This is a massive milestone for us and we’re delighted to mark the
anniversary. We could not be prouder of where we stand today and
thank everyone in our team for all their continued hard work. This
anniversary is not only to celebrate the 30 years of the name but to
also celebrate the dedication of our staff across the UK.”

Lining systems - the importance
of fabrication
By R D Mantle FIoR, Managing Director of Ampteam Limited
Sometimes a spark of clarity will result in
a “eureka” or “light bulb” moment and
an idea will evolve into a unique
product.
I don’t know how many people get such
moments but it is certainly not uncommon as
it is one of the things that makes us Human,
our inventiveness!
Such was the case many years ago when the
idea for the Unifold® hinge was born, only I
called it my “beer mat” moment, because at
the time I was bending a beer mat and you
can probably guess where I was when I was
doing it!
Since those early days of trials, tests,
disappointments and triumphs, Unifold® has
become a complete system and this has been
achieved through an evolutionary process
more by necessity than design, most often
encountering a problem on site and returning
to the factory and solving it in the workshop,
employing fabrication techniques and
whatever tests were necessary to prove the
solution.
Most of the fabricated components which are
vital to the Unifold® system were designed in
the early years of product development and
we had many “light bulb” moments in that
process along the way, such as the patented
Clip Joint used for difficult and narrow
applications.
We learned the use of our hinge principle in so
many ways to aid the fabrication process and
to produce components which would be
impossible any other way. From the outset this
produced fabricated components fit for
purpose and of exemplary quality.
We also realised early on that site working
inside a gutter cavity could often be very
difficult and to expect site operatives to “cut
and carve” and then effectively seal a lining
system was too much to ask, so our intention
was and has been throughout for us to
provide all fabrication, factory manufactured
with simple gutter joints so the installation is
constant and repetitive and as easy as we can
make it.
We became a “single product company”
concentrating on providing product and
service excellence.
The system has proven to be entirely versatile
with the ability to correctly line almost any
existing system whether it is a level gutter or
laid to falls.
Some of our fabricated components are
corners, tees, side boxes, sumps and
expansion joints and these are just a few! In
fact there are solutions for any circumstances
however difficult or complex.
For quite some time now we have insisted that
anyone who installs Unifold must be trained to
install the system. This is to ensure conformity
and continuity of the system quality on site.
This supports our 25 year comprehensive
guarantee that includes the installation as well
as quality of materials and manufacture. An
industry first in gutter lining applications.
It is also without doubt that Unifold® is a
technical product which the following
photographs clearly demonstrate.
The message is clear, any lining system must
be able to cope with whatever the site
conditions dictate and if a 25 year guarantee
is offered then this must warranty that the
system is going to work, without leaking, for
that period of time and beyond.
Our quality and fabrication expertise means
we are content with our promises.
www.gutterliners.com
This first
photograph shows
part of a fabrication
that was probably
one of our most
complex and
certainly one of our
largest.
This is a two
piece corner
detail with an
intruding pier
section.
And this is the complete
fabrication in situ, 18 pieces
in total! And five gutters
entering a single space! Not
easy, and not a common
occurrence, but if you are
going to “set your stall” to
line gutters then the ability
to cope with such
circumstances is elemental
and vital.
This photograph shows a sump unit with
two coned outlets and demonstrating that
each end is a gutter section for ease of
installation. Can you imagine attempting
the manufacture of this on site?

WUFI ® calculation addresses moisture
issues in UK housing stock
As the government strives to improve energy efficiency in the UK housing stock, the solid walls upgrade can cause problems,
which are not readily highlighted within the existing Glaser method of condensation prediction. The current housing stock in
the UK of solid walls, and hard to treat walls, is causing a serious issue on how best to address the thermal solution.
AProctor Group which is renowned for
providing high quality, innovative
solutions for the construction industry
is now leading the way investing in training
and software to predict accurately the
condensation risk in situations where the
Glaser steady state software has limitations.
Iain Fairnington, Technical Director for the
Group explains, “The problem with existing
solid walls is not always recognised and a
designer would be foolhardy to assume the
conditions are likely to be similar to any other
wall conditions. The existing walls, in their
current state, will be breathable, and can
withstand precipitation as they will dry out
throughout the year and there is nothing in
place to stop this vapour movement externally
or internally, with either a vapour control layer
or render. When an upgrade of internal
insulation is introduced the whole dynamic of
the wall is changed, as depending on the
insulation and VCL layer, vapour cannot pass
through the wall and heat cannot dry out the
wall from internal heat drive. This can be
detrimental to the wall structure.”
WUFI calculation highlights moisture issues
A. Proctor Group advises its customers using
WUFI software, which is fully compatible with
BS EN 15026, and dynamically predicts
moisture movement and storage as well as
condensation for each location. The designer
is able to achieve a minute-by-minute
prediction over a given period of years, as
specified by the designer. The programme
considers a worst-case scenario with the
injection of a moisture source at the source to
predict the robust drying out of the fabric build
up.
In contrast, the Glaser Method developed in
1958 for lightweight buildings, uses a
simplified calculation procedure based on
mean monthly temperatures & vapour
pressure, & steady-state conduction of heat to
determine if critical condensation points are
reached within one year.
“A further enhancement of using the WUFI
software is that external weather including
driving rain and solar radiation is predicted in a
cycle and the designer can choose the specific
internal environment that the building will be
exposed to. This has proven invaluable to the
Group when assessing the correct position for
its high performance vapour control and
vapour permeable membranes to ensure a
healthy building fabric, whether it be roofs or
walls,” says Fairnington.
Greater clarity and the way forward
BS5250 will shortly be amended to specify the
conditions when the simplified Glaser
modelling is not appropriate and when the
more sophisticated modelling to BS EN 15026
is needed. WUFI can be used to carry out this
modelling.
“I am delighted that the Group is offering this
service to customers who are utilising our
products to ensure that their building
envelope remains healthy, and effectively
ensures that the balance of heat, air and
moisture is addressed to achieve the ultimate
performance,” concludes Fairnington.
For over 25 years A. Proctor Group has been
providing their customers with excellent
technical advice on a range of products, from
acoustic flooring (produced in their own
acoustic laboratory), U values showing
thermal performance, contaminated land gas
mitigation designs, SBEMS, SAPS and
condensation predictions. This has led to A.
Proctor Group being recognised by many
within the construction industry as a key
problem solver and a trusted resource.

Keymer tiles used in relaying of period
roof on The Old Vicarage
Keymer’s Traditional Elizabethan and Antique roof tiles have been used to restore the roof of the Grade II listed building and
period home, The Old Vicarage in Suffolk. The project, which is now completed, was undertaken by house owner Tim Pitt, who
was looking to ensure that the roof of the period property was beautifully renovated with respect to its heritage, keeping the age
and period style of the building feel. The new appearance and look of the renovated roof is outstanding.
The building, which has been listed
since 1961, was in need of a complete
reroofing, and due to the Grade II
listing of the property, required the tiles used
to fit in with the overall aesthetic of the
property.
In selecting a 50/50 mix of Traditional
Elizabethan and Antique tiles, the home boasts
completely handmade heritage clay tiles,
which the home owner believed were the
closest match to the peg tiles expected to be
seen on a house of this period and in this
location, whilst also being a significant
improvement on the machine made plain tiles
that were slaking and falling from the roof.
Christine Leadbeater, Client Development
Manager for Keymer, commented:
“We’re very proud to have been involved on
such a prestigious project - The Old Vicarage
is a very impressive home, and one that we’ve
been aware of for over a year, so we were
thrilled to have been able to support on. The
selection of Keymer tiles used by Tim fit in
perfectly with the historic property and the
nearby surroundings of the area, and having
now seen the finished product, it truly looks
incredible.”
Speaking about his project, Tim Pitt said:
“I selected Keymer tiles to be used for the
relaying of The Old Vicarage roof as they are
the best hand made tiles on the market, and I
was looking replace machine made plain tiles
that were in place when I purchased the
property. The Traditional Elizabethan and
Antique tiles were undoubtedly the closest
match to the peg tiles I would have expected
to see on a house of this period and in this
location. I’m delighted with the outcome and
very happy with how the new roof looks.”

Fire Protection, Safety & Security
No Compromise on Safety
Rex Taylor, Technical Support Manager of Kidde Safety, calls for better provision of smoke and carbon monoxide alarms with
housing refurbishment.
Without doubt, smoke and heat
alarms save lives and housing
refurbishments offer an ideal
opportunity to update them. Definitive
guidance can be found in BS 5839, Part 6,
which lists the minimum ‘Categories’
(locations for the alarms) and ‘Grades’ (types
of power source in the alarms)
recommended for different types of housing,
including owner-occupied and rented.
Heat Alarms in all Kitchens
For most homes up to 3 storeys, the Code
recommends ‘Category LD2’. This means
smoke alarms in any areas where fires might
start, such as living rooms, as well as escape
routes, plus heat alarms in every kitchen. With
converted properties and new-builds, national
Building Regulations apply and those for
Scotland and Northern Ireland mirror the
Code.
But in England and Wales, Approved
Document B falls short, requiring only
Category LD3 with smoke alarms just in
escape routes and heat alarms only in kitchens
open to escape routes. Yet, as the Code
stresses, with Category LD3 the evacuation
time once fire is detected in the escape route
“might not prevent death or serious injury of
occupants of the room where fire originates”.
Building Regulations and the Code are all
agreed in demanding Grade D mains with
back-up, interconnected smoke and heat
alarms for all new and most existing homes.
These should always be interconnected so
that all the alarms sound when one is
triggered. But there are often reasons to avoid
interconnect cabling in existing buildings.
Here, wireless interconnection is an ideal
solution, with each alarm simply powered
from a lighting circuit nearby. Some wireless
ranges also offer additional facilities, for
example a remote switch to control an alarm
that might otherwise be difficult to access.
This is particularly useful for elderly or disabled
people, or where alarms are fitted on higher
ceilings.
Curbing CO Poisoning
There is also a strong case to fit carbon
monoxide alarms in all homes. The latest
guidance is provided by BS EN 50292:2013. It
recommends that, ideally, a CO alarm should
be installed in every room containing a fuelburning
appliance and also in other well-used
rooms remote from the appliance, as well as
all bedrooms. In addition, rooms with
extended or concealed flues passing through
should also have an alarm.
Building Regulations throughout the UK all
require CO alarms to varying degrees but only
with installation of new or replacement
combustion appliances – and that excludes
those used for cooking. In particular, BS EN
50292’s more rigorous approach contrasts
starkly with Approved Document J for England
and Wales. This only demands a CO alarm
with installation of certain, solid fuel heating
appliances. The continuing toll of deaths and
illness associated with other fuels and types of
combustion appliances – including cookers –
highlights the need to raise the bar with
carbon monoxide.

KO for CO
Long-term reliability is more important than ever for cost-effective safety and carbon monoxide alarms with a proven 10-year
guarantee are raising the bar, as Kidde explains.
Although not a replacement for regular combustion appliance servicing, working carbon monoxide
alarms in homes are essential in curbing the silent killer and a legal requirement in many
situations. Uninterrupted performance is key and Kidde’s 10LLCO and 10LLDCO models are the
only 10-year guaranteed CO alarms with sensors – the key component – actually tested throughout a 10-
year period or longer. Especially designed for quick and simple installation and with low cost of
ownership, they offer ‘Best Value’ over a 10-year life and are ideal for owner-occupied, private rented and
social housing.
Feature Packed
These alarms are full of features including “Quick Test” functionality whereby the unit can be tested with CO
gas spray and react instantly to confirm the presence of carbon monoxide, rather than the normal response
times required in BS EN50291.
They have an extra End-of-Life/Fault LED and an alarm sounder designed to protect occupants and
installers’ hearing when testing, with an initial lower level of sound being generated.
Small and with a slim profile, both alarms can be wall-mounted or used free-standing. Simply activated by
the slide-on back plate, so preserving battery freshness until needed, they incorporate a tamper resisting self-locking installation system that avoids
battery theft. An event activity data log for each alarm is also available, upon request from Kidde. The 10LLDCO model also has a digital display to
provide early warning of intermittent and low levels of carbon monoxide. And a ‘Peak Level’ button can help identify carbon monoxide events
occurring when the property is not occupied.

Fläkt Woods provides a ventilation & fire
safety for Birmingham New Street station
Fläkt Woods, a market leader in air movement technology, has supplied a ventilation and fire safety system at Birmingham New
Street station, which was installed during the £750m transformation of the facilities.
Birmingham New Street platforms at night
Birmingham New Street tunnels - West Midlands
Fire Service perform exercise prior to opening
Birmingham New Street station was
officially opened by Network Rail in
September 2015, following a five-year
refurbishment programme. With an iconic
new atrium over a passenger concourse five
times the size of London Euston's, the station
has brighter, de-cluttered platforms, improved
entrances and a range of new facilities.
One of Britain's busiest inter-change stations,
Birmingham New Street also has 43 shops at
concourse level, and above it sits Grand
Central – a 450,000sq ft shopping complex
that includes one of the largest John Lewis
department stores in the UK.
Fläkt Woods provided a Jet Thrust System for
daily ventilation and fire safety, with over 100
fans fitted above the track at platform level. In
addition, 14 control panels and over 100
carbon dioxide (CO2) detectors were supplied,
in a contract worth £1.2 million.
The system provides life safety should a fire
occur on platform level, by maintaining clear
escape routes for occupants and a safe, secure
area for West Midlands Fire Service to access
and fight the fire. The system ensures that
smoke will not travel up the open stairs and
escalators to the concourse level above, which
allowed the architect to remove line-of-sight
blocking fire doors from the platform level.
In emergency mode the system also allows for
directional flow of smoke along the platform.
Under the extreme design conditions imposed
on this very busy public building this also
provides more tenable conditions for fire
fighters during the latter stages of a fire.
Fläkt Woods worked with client Mace/Network
Rail and key contractor NG Bailey to ensure the
most suitable solution was provided, and,
importantly, that the system could be installed
while the station remained open.
An initial study for the jet thrust system was
provided to confirm that the concept was
workable, and following this Fläkt Woods
provided a continuous design service as details
evolved on site. This included a presentation of
results to key stakeholders and increasing the
life safety requirement of the system, for
example by removing the fire doors and
changing the platform access layout. As part of
the continuous design process it was also
agreed that the fans would be painted black to
better match Birmingham New Street’s ceiling.
A factory acceptance test was provided before
installation of the fans to make sure the
customer was happy with their performance
and the low noise they generated.
The fans were installed during a ‘temporary’
phase, allowing both the existing and new
ventilation systems to coexist, meaning there
was no reduction in fire safety protection to
the platforms.
The new system offers a number of benefits
over the existing one. Whereas the existing
system operated at full speed 24 hours a day,
seven days a week, the new one operates on
demand. Therefore, when electric trains pass
through the station the system does not
respond, as there are no pollutants, and diesel
trains only activate the system as pollutant
levels start to build up in the occupied zone,
rather than in the void above the tracks. The
speed of activation is modified depending on
the levels of pollutant detected on a perplatform
basis, and the system is designed to
operate with any prevailing wind.
The fans can be maintained from platform side,
which means Network Rail doesn’t need to use
maintenance trains to access the units from
the track – as would have been required with
the original system.
Ross Barritt-Mehta, operational marketing
manager for fire safety at Fläkt Woods, said:
“Birmingham New Street station was rebuilt
while trains continued to run as normal for the
170,000 passengers a day who use it –
understandably making this a challenging
project.
“The existing cooker-hood style ventilation
system could not be removed before the new
system was installed, and any new extract
ductwork could not pass through the building
above as the existing system did, as the area
was to be opened up for the shopping mall
atrium.
“This project has given Fläkt Woods an
invaluable opportunity to prove its expertise in
designing, modelling and providing a highly
complex system.”
Fläkt Woods also provided jet thrust systems to
the short stay and drop and go car parks and
loading bay within the Birmingham New
Street site.
Fläkt Woods is a leading manufacturer of
ventilation and air movement products.

Forbo offers range of floor
treatments at hospice
Forbo Flooring Systems was recently involved in a major refurbishment project at Naomi House Children’s Hospice in
Winchester, supplying a range of products that have helped to create stimulating and calming environments whilst addressing
key areas such as safety, hygiene and infection control.
David Golland of Building Surveying &
Project Management Ltd managed
the partial demolition and rebuild of
the hospice. He commented: “I’ve worked
with Forbo many times over a long period so
I have a good relationship with them. They
were very helpful in assisting in the selection
of appropriate floor coverings for this
project.”
One area that presented a challenge was the
main corridor that curves around the
building. Forbo proposed Marmoleum Striato
in Colourstream which has multi-coloured
crayon-like stripes. Carefully shaped and cut,
the resulting floor is hygienic and
hardwearing and makes a strong visual
statement.
Using Flotex Vision, a calming cobblestone
pattern has been created in an area used by
parents visiting their children. Flotex is very
durable as the pile is constructed from
millions of tightly packed upright nylon fibres
that also give the flooring excellent sound
absorption properties. Forbo’s unique hybrid
product has also earned the Allergy UK Seal
of Approval for the way in which allergens are
trapped within the pile and released to
standard cleaning appliances. David said:
“The Flotex has been laid in a quiet seating
area where parents can take a break and
enjoy the views of the garden. The area has
full height glazing and the cobblestone
pattern ‘brings the outside in’. This flooring is
fully washable and resilient but it has the feel
of carpet, so it really helps to create a
comfortable environment.”
Surestep Laguna safety flooring has been
used in hospice bathrooms, and bold patterns
featuring footsteps, bubbles and dolphins
have been created for the enjoyment of all
the young patients, even those with profound
disabilities. Surestep Laguna offers barefoot
and footwear slip resistance and has been
designed to maintain its fresh and clean
appearance. Made from 60% recycled
materials and 100% recyclable, it offers an
environmentally friendly flooring solution.
Mark Smith, Chief Executive of Naomi House
said: “A key part of the project design brief
was to balance the clinical needs of a
modern hospice with our desire to create a
homely environment for the children and
their families who use the building. Forbo
helped the team to select a variety of floor
coverings for the different parts of the
building, creating innovative design solutions
whilst satisfying the requirements of infection
control, resulting in a fabulous interior which
is enjoyed and admired by all who use it.”

Cream of the crop
The UK headquarters of much-loved digital print and design business MOO has returned to EC1, just 500m from where the
business started out ten years ago, and in the heart of London’s original 18th Century printing district.
20 Farringdon Road now houses all
central London-based employees in a
35,000 square foot space that has been
designed to accommodate MOO's long-term
growth plans as the company enters its 10th
year.
The design of the office has been of
paramount importance to this print business
that operates at the intersection of technology
and design. As a visual reminder that paper is
at the heart of MOO’s business, a central
feature is a 60-metre-long paper installation
suspended from the ceiling along the main
spine of the office.
Created solely by MOO’s in-house product
team, the feature is constructed from over 500
panels of beautifully crafted Colour Plan paper.
The rectangular panels were milled in the UK
by long term MOO partner G F Smith. At
1600gsm thick and in 26 different tones, the
paper creates a unique rainbow effect focal
point in the space.
MOO’s love of design also shines through in
the special attention that has been paid to the
abundance of soft seating areas, break-out
spaces and meeting rooms. Creating an
environment that would fuel collaboration
was also a priority, so the office flows across a
single floor, enabling all the company’s diverse
teams to co-work across the generous lateral
space.
The refit took just 32 weeks to complete,
thanks to MOO’s build contractor, Peldon Rose
and the expert interior design eye of longterm
MOO design collaborator, Trifle Creative.
“It's great to be back in our old
neighbourhood, almost 10 years after MOO
started out here,” said Richard Moross, MOO
Founder and CEO. “Clerkenwell and
Farringdon have a rich print history, but the
neighbourhood also connects the design and
technology industries of EC1 and EC2, making
us feel very much at home in the middle of it
all.
“As a values-led business we needed an HQ
that reflected our beliefs. We jumped at the
chance to put our unique mark on the space,
something only made possible by a lot of hard
work, attention to detail and creativity from
our contractors, creative partners, internal
design team and all of those who were
involved in the project.”
MOO operates globally, employing 400 people
and serves more than 190 countries across six
locations in the US and the UK.
Key facts:
• Entire space is 121 metres long and 40
metres wide (or the equivalent of 3 Olympicsized
swimming pools).
• 25 styles of light fittings have been used,
mostly LEDs but also bespoke pendant lights,
including some by British designer Tom
Dixon.
• The space has two kitchens, as well as a
functioning coffee bar and a circular private
dining room.
• MOO has collaborated with Supermundane,
whose mesmerising signature illustrative
style is featured on one of the walls.
• All desk chairs are by Herman Miller, while
Trifle commissioned a range of bespoke
pieces including mobile whiteboards, a long
concrete reception desk, layout and storage
units and communal central tables and
benches.
• Crittall Windows have been used to separate
the meeting rooms. Renowned for their
galvanised steel window frames
synonymous with the Modernist movement,
they enhance the industrial feel of the space,
while ensuring meeting rooms remain
flooded with light.
The rainbow spine is an eye-catching feature

Changing places riding high
“You can’t turn people away because you haven’t got a toilet.”
So says Sorrel Taylor, centre manager at Clwyd Special Riding
Centre. And she won’t have to turn away anyone now, with the
installation of a ‘state-of-the-art’ Changing Places toilet facility for
visitors, supplied and installed by Clos-o-Mat as a result of fundraising
activities by the Centre.
Founded 30 years ago, the Centre provides equine therapy
opportunities for children and adults with additional needs. The
team of 24 specially-trained ponies and horses, a mechanical horse,
11 staff and over 150 volunteers provide opportunities for visitors to
experience time with a horse, ranging from just spending
groundwork time with an equine, riding, to carriage driving, show
jumping, and hippotherapy. Visitors can come for just a couple of
hours, or take advantage of a residential equestrian holiday.
“Horses mirror our emotions: they offer experimental learning and
allow for development in confidence, non verbal communication,
self-awareness and overall wellbeing,” explained Sorrel. “We are
constantly striving to develop the Centre to be able to offer
opportunities for a greater number of individuals. Many of our
visitors do need help going to the toilet, so the Changing Places
facility is a much anticipated development.”
Larger than a conventional wheelchair-accessible toilet, to give
space for the user and up to two carers, the Changing Places also
has as standard a hoist and adult-sized height adjustable changing
bench. Clwyd Special Riding Centre’s facility also features a Clos-o-
Mat Palma Vita wash & dry toilet in place of a traditional WC: looking
like, and capable of being used as a conventional toilet, the Palma
Vita has built-in washing & drying facilities, so the user is efficiently
and hygienically cleaned without them, or their carer(s) having to
manually wipe with toilet tissue.
“Including the Clos-o-Mat means all people accessing the Centre
will be confident that their needs can be accommodated,” added
Sorrel.
Under current building guidelines and legislation, Changing Places
toilets are now ‘desirable’ in any building to which the public has
access. Since the concept was devised, over 800 have been opened
in venues across the country.
Clos-o-Mat is Britain’s biggest provider of fully accessible toilets,
including a substantial number of Changing Places facilities. It is
unique in its ability to deliver- in-house- design advice, supply,
installation, commissioning, project management and maintenance
across the gambit of accessible toileting equipment, including the
Clos-o-Mat wash and dry (automatic) toilet. To help leisure venues
‘get it right’, Clos-o-Mat has a raft of downloadable information on
its website, www.clos-o-mat.com, including sector-specific white
papers, CAD blocks, room renders and videos.

The best way to board your loft - StoreFloor
Utilising loft space and the methods of allowing safe access to this space can be tricky. Heavy timber boarded directly on to the
joists can cause real issues and changes to insulation and building regulation requirements mean that traditional methods now
are growing obsolete.
There is a new method, which is the
first method approved by BBA, to
circumvent these problems. LoftZone
StoreFloor's raised decking system allows for
safe access to the loft space in buildings,
whilst also allowing 350mm or more of
insulation to be laid underneath. Research by
the National Physical Laboratory and Carbon
Trust has shown that loft insulation is often
compressed to joist height to allow for safe
access walkways, and that this reduces its
effectiveness by at least 50-60%. The
LoftZone system allows you to meet Building
Regulation requirements (Parts K, L and P),
but also safe access for all storage and
maintenance purposes.
How it works:
The LoftZone system works via placing the
patented tri-supports, along with singular unisupports,
directly on to the joists. A metal
cross-beam is then placed on top, which then
allows for boarding to be screwed down on
top. The height of the tri-supports allows for
the full 350mm of insulation to be laid out,
whilst also allowing for an air to pass above
the insulation. This removes compression of
the insulation, ensuring maximum benefit
when it comes to energy efficiency.
The system also allows for handrails to be
installed, so as to comply with Working at
Height Regulations (Part K, BS6180). Loft
ladders can also easily be installed on to the
boarding for easy access.
Advantages:
LoftZone StoreFloor is very lightweight and
also quick to install when compared with
other methods of loft insulation. It's ideal
compared to traditional methods such as
adding extra timber directly on to the joists,
which obviously add weight and go against
Part L1A of the UK Building Standards.
LoftZone has already been put to good use at
the Oasis Academy Connaught school in
Bristol, where the system was installed during
refurbishment works. Aedis Building
Consultancy specified use of the LoftZone
system at the school, commenting: “Our
objective was to provide safe access in a large
roof void that was simple to install, cost
effective and would not compromise the high
level of thermal insulation we installed. The
LoftZone product met this objective and we
are very pleased with the results”.
One of the other advantages of LoftZone is the
speed of install. It only takes approximately 15
minutes to install 3m 2 of LoftZone kit. This is
due to the adaptability of the system when
encountering issues with problem/warped
joists, wiring etc.
Whereas other methods of loft boarding may
require extra timber to be put on to these
joists, LoftZone can simply bridge over them
and therefore cuts down on this excess work
time.
The LoftZone deck is often installed alongside
solar panels or MVHR units (or indeed any
other equipment in the loft), since it provides a
safe access deck for future maintenance of
said equipment.
LoftZone has many different practical
applications and is suited to a wide range of
projects. The raised loft floor is suited to both
residential as well as commercial properties
and benefits can be easily seen in both.

Zehnder ComfoAir Q
diamond heat exchanger
Energy Efficiency
Zehnder’s ComfoAir Q Heat recovery unit
achieves Passivhaus certification
Outstanding 96% heat recovery efficiency from next generation MVHR
ComfoAir Q
Zehnder Group UK is proud to announce
that its new ComfoAir Q range of
MVHR units – the most efficient heat
recovery system on the market - has been
awarded Passivhaus certification. This new
generation of heat recovery units offers
outstanding energy and noise performance
as well as smart technology that helps
improve the installation process and
accuracy on-site.
Why Choose MVHR?
Modern homes conform to stringent, energyefficiency
regulations and the choice of
heating and ventilation system is crucial to
achieving these standards and maintaining a
comfortable, energy efficient and healthy
indoor environment. When a fabric first,
energy efficient approach is taken to new
build, MVHR (mechanical heat recovery and
ventilation) really is the only choice - a whole
house system that works to maintain and
deliver fresh air 365 days a year.
Working across every new build sector, from
social housing to luxury high-end
developments, Zehnder has built up a
reputation as both a leading supplier and
authority on heat recovery systems and has a
particularly strong position in the Passivhaus
marketplace. Looking to build on this tradition
for innovation and excellence and following
extensive research and development, it is
proud to introduce the new ComfoAir Q
range. The next generation of MVHR unit.
Key Benefits of Zehnder ComfoAir Q Range
• World Class Performance: The range
provides up to 96% heat recovery efficiency,
making it the most energy-efficient unit on
the market and providing the greatest energy
savings to homeowners and energy bills.
• Elimination of nuisance noise: Zehnder
ComfoAir Q units are almost silent during
operation and are currently the quietest units
on the market. Did you know that for every
3dB increase, the sound you hear doubles?
ComfoAir Q = 42dB(A), while other MVHR
units = 50dB(A). This means that one
comparable MVHR product emits the same
amount of sound as eight ComfoAir Q units.
This has been achieved through the use of
innovative components designed to work
together in perfect harmony, including stateof-the-art
fan technology.
• Simple to Install: Connections can be
changed from right to left, ensuring that
everything fits even when the installation
situation is modified.
• Convenient to commission: A simple,
integrated commissioning wizard and app
assists with setting up the system exactly as
required. The commissioning process
concludes with an automatic system test and
confirmation, allowing the new unit to be put
into operation easily, quickly and safely.
• Improved Indoor Air Quality: Completely
sealed and maximised, the high-quality filters
ensure healthy, dust-free air and protect
against excessive humidity.
• Smart homeowner control: A convenient
app gives customers the right operating
solution whatever their needs.
• Maintenance: Systems can be monitored
easily via remoted access on the Zehnder
web portal. In addition, the units have easy
access for cleaning.
• Three sizes available: 350, 450 and
600 m³/h.

Ideal Commercial Boilers work out at
Lymington Health & Leisure
Four Ideal Commercial Evomax 100 boilers with frame and header
kits have been installed as part of an extensive retrofit at the
Lymington Health & Leisure centre in Lymington, Hampshire. The
new Evomax boilers, which were specified by loyal customer New Forest
District Council, were installed in the boiler room to supplement two
older, standard efficiency boilers which were deemed to be inefficient
and did not modulate, meaning output was all or nothing when fired.
New Forest District Council have implemented a programme of
refurbishments across numerous council sites involving Evomax and other
Ideal Commercial boilers. The council has found the combination of ease
of installation and high efficiency readings to be very impressive, along
with an attractive appearance. The introduction by Ideal of the new
Multiline cascade flue assembly allowed more of the work to be carried out by the council, thereby reducing the cost of the flue specialist materials
and labour.
Rob Sowden, Council Engineer for New Forest District Council, was able to carry out the majority of the installation himself as well as ensuring
continuous hot water between the old and new systems. Rob was particularly impressed with the support he received: “As usual, the technical
back-up from Ideal Commercial Boilers was exceptional, especially in the design stage, making sure that we complied with all current regulations.”
The new Evomax boilers also make sense financially. “We are predicting a 10% saving on the gas bill every year which equates to £4,000 per
annum. The complete project cost under our £30k budget so, at current gas costings, we are hoping the Evomax boilers will pay for themselves in
six or seven years,” Rob said. Additionally, the leisure centre can look forward to a quieter boiler room as the existing boilers were very noisy when
running.

Oxford Brookes University finds the answer
with EyeNut
Oxford Brookes, one of the UK’s leading modern universities, has chosen the EyeNut
monitoring and management system from world leader in the design and
development of wireless lighting controls Harvard Technology, as its lighting
control system of choice.
The university, which has so far rolled EyeNut out across three buildings, initially achieved
savings of 30% through the implementation of control strategies including daylight dimming
and occupancy detection.
Oxford Brookes then requested an illuminance capping exercise was performed to ensure
light levels were in line were recommended standards and user preferences. Harvard
assessed the university’s lighting in accordance with the Chartered Institute of Building
Service Engineer’s (CIBSE) interior lighting guide.
Lighting inside Oxford Brookes University
It was found that lumen levels were 15% to 45% higher than the users required. By capping lighting in line with CIBSE recommendations, energy
was reduced by a further 27%, equating to total savings of 48%.
Steve Holtom, energy manager at Oxford Brookes University, said, “We never thought that we would be able to achieve such impressive savings by
implementing a lighting control system. We are now looking at rolling EyeNut out across further sites, including student residence blocks. Now we
have the system in place, installing EyeNut in additional buildings is really easy and cost-effective.”
Colin Shockledge, specification manager at Harvard Technology, added, “We are really happy with the savings gained at Oxford Brookes University.
EyeNut is a fantastic solution for universities, allowing remote access controls over the whole estate not only in new build situations, but in
particular within older heritage buildings. However, regardless of the industry leading wireless connectivity, the main purpose of EyeNut is to save
energy and this study has proven the effectiveness of the system” he said.
The installation of EyeNut is part of Oxford Brookes’ 10 year estates refurbishment plan. So far, when factoring in the other three buildings currently
under refurbishment, savings achieved by EyeNut have equated to substantial financial reductions of £13,000 per annum.

Pegler Yorkshire
Completes Static
Valve Offering
To ensure heating and
ventilation systems
work to their
optimum efficiency valves
are a key element. Pegler
Yorkshire with its
foundations held in the
development and
manufacturing of valves, is
increasing its Static Valve
offering which incorporates
ultra low and medium flow
static products to
compliment all flow
variables.
“Standard practice of installed
HVAC systems is to ensure
minimal loss of hydraulic
flow. Therefore, regulating
flow and keeping pressure loss to a minimum is essential in the
optimum efficiency of a system,” said Sindar Singh, Climate
Control Market Manager for Pegler Yorkshire
Within the Ballorex Commercial Valves range the Pegler 1260 fixed
commissioning double regulating valves incorporate a fixed plate
orifice for accurate flow measurement and regulation. The design
includes an oblique pattern body and easily accessible test points
for use during commissioning.
The company has developed straightforward valve selection
process targeting ‘application areas’ which ensures the right valve
is chosen to support function, size, performance and optimization
The three key areas are identified as Source – which is focused
around plant / boiler centres, Network which encompasses the
distribution of heating and potable building systems, and finally
the Zone that is the occupied function zone, such as an
apartment, office or ward where the heat or water is emitted.
We can safely say that requirements for the Source area would be
centred on large sized valves.
Within the Network area valves are used to control water flow and
balance the heat and cooling distribution to different locations.
The next point of use is classed as the Zone area, for example
heating, this consists of pre-set valves for either panels or radiators
through to modular valves units used on fan coil units
“The additional valves incorporated into the Ballorex portfolio will
mostly be used within the Network application area”concluded
Sindar.

Titon’s Trimbox No2 filter named ‘Best Health and
Safety product’ at Housebuilder Product Awards
Titon was victorious at the recent Housebuilder Product Awards on 29 June 2016, with
its new Trimbox NO2 Filter® winning in the 'Best Health and Safety Product' category.
Designed to reduce nitrogen dioxide (NO2) emissions in the home as part of a Titon
Mechanical Ventilation Heat Recovery (MVHR) system, the Trimbox NO2 Filter® allows 'clean'
air into a property, creating a healthy indoor environment for its occupants.
Commenting on the accolade, Stephen Lilley, Design & Development Engineer for Titon, stated:
"It is great for the product to be recognised for its health and safety credentials. Our aim was to
make people more aware of the issues that NO2 causes within the home – especially in urban
areas which suffer from high levels of traffic pollutants. By designing the Trimbox into a MVHR
system, it will absorb over 95% of NO2, reducing respiratory issues that can arise".
The Trimbox NO2 Filter has been developed to complement its extensive range of HRV Q Plus
Eco MVHR units to combat the high levels of NO2 found in exhaust gases from diesel engines in
urban areas. The Trimbox NO2 Filter incorporates balanced flow technology to provide class
leading absorption of NO2 and is available in two duty sizes (depending on the duty required).
The Trimbox NO2 Filter is highly effective in reducing pollutants in urban homes (including
sulphur dioxide, hydrogen sulphide, hydrogen chloride and chlorine), improving IAQ and
reducing the risk of Toxic Home Syndrome and the ailments associated with air pollution. The
filter also performs well against ammonia odours. As with other impregnated grades of activated
carbon, it will also adsorb the same contaminants as impregnated carbon, e.g. volatile organic
compounds and solvents.

Nationwide Windows Ltd makes nationwide investment
Leading fenestration partner to the
social housing, new build and
commercial sectors, Nationwide
Windows & Doors is living up to its name by
making further investment into its network
of depots across the UK.
Daryl Cashmore, Operations Director at
Nationwide Windows & Doors comments:
“Thanks to the recent win of a six-year
contract with Cheltenham Borough Homes,
we’ve just opened a new depot in
Cheltenham. This has seen an investment of
around £875,000 and the aim is to support
current and potential new contracts in the
South West. There will be twelve fitting
teams operating from this depot servicing
around 5,000 properties in Cheltenham,
Gloucester, Bristol and Swindon. As well as
the fitting teams we will also be employing a
team of admin and support staff, with a
workforce totalling thirty-five employees.
“We’ve also made further investment into
other areas of the country. As recently
announced, the Nottingham depot has
moved into a larger premises. We’ve worked
with Nottingham City Homes (NCH) since
2008 as a preferred partner on the Secure
Warm Modern Programme initially covering
15,300 homes. Thanks to the continued
successful partnership with NCH the move
sees our capacity in the area increase to
18,872 square feet, allowing for further
growth.
“And investment doesn’t stop there. A new
retail showroom has been opened in London,
and is a facility that allows us to showcase
our extensive product range as well as
support the work we carry out with
Metropolitan Homes and a Noise Attenuation
Scheme in the London area. In order to better
service our customers in North Wales and the
North West of England, the current Bangor
depot has been absorbed into a new larger
premises in Deeside. The new depot is 5,700
sq feet and will see an investment of
£650,000 over the next five years.
“These are exciting times for Nationwide
Windows & Doors as a company but also a
reflection on the positive market place we are
operating in. We are very proud of the
fantastic partnerships we have developed
across the country in both social housing and
new build. Sustainability and community
support where we live and work has always
been a core principal for our business. These
recent investments allow us an employer to
establish local jobs and training for new skills,
qualifications and life opportunities. To be
able to continue expansion investment across
the UK was the logical next step to securing a
longer term future for us and our partners.”

New Spider system brings UFH
solution
A £5m project to rebuild Kenwick
Leisure Centre in Lincolnshire has
incorporated underfloor heating from
Giacomini. When selecting the UFH,
the contractors Nigel Smith Plumbing
and Mechanical Services Limited
chose Giacomini’s new Spider system,
making the leisure centre the first
installation of the new system for
Giacomini.
The Spider system has been designed for projects requiring
UFH but with limited floor depth due to room height
restrictions. It has a patented geometry that enables the UFH
system to be embedded in just 3cm of screed.
The Giacomini Spider system is available in three
configurations, and the Kenwick Leisure Centre uses the
R979SY021 which has a 6mm layer of HD insulation glued to
the underside of the panels. This helps to reduce downward
heat losses, whilst keeping the floor build-up to a minimum.
With adhesive bases, the Spider system is very easy to install
and offers a flexible and practical cutting-edge radiant floor
solution.

Kingspan updates guidance for high
rise fire safety compliance
With an ever increasing demand for
affordable homes and commercial
developments where space is
limited, developers need to be able
to build upwards; creating highdensity,
high-rise communities. To
ensure such purpose-built
constructions adhere to complex fire
safety regulations, as well as tackling
misconceptions surrounding the use
of insulation in rainscreen and
masonry façades, Kingspan
Insulation has released its second issue technical bulletin which
focuses on buildings with habitable storeys 18m or more above
ground level.
The improved ‘Routes to Compliance: Fire Safety’ bulletin features a
general overview of the linear, performance-based, and fire safety
engineering routes; offering stakeholders an easy place to check if
their desired build-up follows the best route to compliance.
In addition to the technical bulletin download, the ‘Routes to
Compliance’ page hosts a selection of other resources, including a
short video on the different approaches to compliance. Kingspan
Insulation’s technical experts can also provide practical guidance and
can be contacted for further information on

Hunter Douglas showcases expertise
at £16m leisure centre
The showpiece £16 million leisure and
community centre at Ashington in
Northumberland includes two stunning
ceiling systems, manufactured by Hunter
Douglas.
The first – a visually striking 640m2
wood linear open ceiling – stretches
across the entire entrance and main
atrium. Finished in American red oak, it
was made to 111mm module, with each
plank measuring 92mm x 15mm.
Hunter Douglas’ special demountable clips, which allow up to
50% demountability, were used, while the 19mm gaps between
the linear wood panels are visually closed by an acoustic fleece to
improve interior sound absorption.
Hunter Douglas also manufactured and supplied expanded metal
acoustic rafts beneath an exposed soffit in the gymnasium. Made
to a 1000 x1000 module, they have regular edges to fit a standard
24mm ceiling grid and include the Hunter Douglas LS10 stretch
metal pattern.
Black acoustic pads, which provide high levels of acoustic
absorption to offset the noise generated by the fitness
equipment, were fitted to the rear of the ceiling panels.

Company Profile
Pushing the envelope
Refurbishment contractors SPV Group specialise in design and build renovations of existing hotel, leisure and office buildings.
We speak to Howard Evans, Managing Director and Kate Whatley, Commercial Director about how building envelopes are so
much more than just a facelift.
Albany House,
before and after
What are the main services you offer to
clients?
Howard: SPV can offer project design and
construction on large scale renovation projects
in the commercial, retail, leisure, industrial and
educational sectors.
Now incorporating SPV Roofing & Cladding,
SPV Windows, SPV Shopfitting & Building, Ivor
Parnham Building Services, SPV Energy
Management Systems, and SPV Plant, SPV
Group offers a multitude of disciplines and
services to provide the complete package for
your building needs.
What’s the main benefit of a building
envelope refurbishment or renewal?
Kate: A dramatic effect can be achieved
through updating the building envelope of
buildings.
It is a very cost effective solution to
modernising the look of the tired façade of the
building to create a fresh presence in the area.
You operate a ‘single point of contact’ service
– how does this benefit the client?
Kate: A single point of contact has many
benefits for the client. All divisions within the
group work cohesively to ensure projects run
smoothly and efficiently and ensure the client is
kept updated throughout but not troubled
unnecessarily.
Howard: Driven by a desire to go back to old
fashioned values - by way of championing the
importance of communication and
collaborative working – the different divisions
of SPV draw on their individual areas of
expertise to address specific project
requirements.
Which manufacturers do you work with?
Howard: On the Albany House project, SPV
worked closely with Marley Eternit who we
procured through FGF Ltd in Birmingham and
were delivered to site on a just in time basis by
FGF.
What are the other benefits to clients?
Kate: The Albany house project is an 11 storey
office block in Birmingham city centre. When
we first started on the project, the offices were
around 40% let, but when we handed over the
project, the offices were 100% let, with
Birmingham Hippodrome and The Bangladesh
Embassy occupying space within the building.
This demonstrated the return on investment for
clients to undertake building envelope
upgrades.
What would you say was the company
ethos?
Howard: The SPV ethos is that of honesty,
integrity and collaborative working.
Our mission statement is “To be the leading
provider of high quality roofing, cladding and
glazing solutions in the UK refurbishment
sector going above and beyond the
expectations of our clients.”
With over 30 years of experience in the industry
and an excellent reputation, SPV prides itself on
its professional, superior quality of service, high
standard of workmanship and our ability to
always working very closely with all our clients.
Albany House in Birmingham was a recent,
large project. What did that comprise?
Howard: The office building which is owned
and operated by RVB Investments has been
refurbished with a new external facade system
and new glazing to all elevations.
The property is an eleven storey building that
includes both cellular and open plan office
suites with passenger lift access to all floors
approached via a marbled entrance lobby off
Hurst Street.
The project involved stone and concrete repairs
to the existing building followed by the
installation of 2800m2 of Marley Eternit
Equitone Cladding panels to all elevations in
four different colours - Onyx, Azure, Bluestone
and Muted Stone.
All existing windows were removed and
replaced with new Technal aluminum
windows.
SPV completed the works whilst the tenants all
remained in the building, undertaking noisy
works out of hours and ensuring as little
disruption was caused to the building users as
possible.
The client is delighted with the finished project,
commenting that the works have improved the
profile of the surrounding area and have also
transformed the previously drab looking
concrete structure into a vibrant and modern
aesthetically pleasing building.
