We all love to talk about houses. We watch
hours of TV programmes about renovating
them, buying them and selling them, and
house prices are an endless fascination for
millions of people, whether or not they have
made it onto the housing ladder.
Then there are the millions of us whose work revolves
around housebuilding – whether that’s as a specifier,
architect or contractor, or one of the millions of supply
businesses who sit alongside the housing industry.
Housebuilding now accounts for 60% of all new
construction work, and when the housing market is down,
it has a knock-on effect on the entire UK economy. That’s
why, despite the difficult times we have been experiencing,
it’s encouraging to see the first positive signs that private
housebuilding could be recovering with new project starts
rising (see page 6).
Even as these short-term challenges begin easing, longer
term there is much work still to do, particularly around
energy efficiency and decarbonisation, where the race to
net zero means it’s more important than ever that you make
the best product and material choices.
That’s why many of the case studies we’re looking at
this month focus on energy efficiency and renovation work.
Plus, given that 40% of all new construction work isn’t
private housebuilding, we’re also taking a closer look at the
Commercial, Retail, Hotel and Leisure sectors, to assess
changing trends that could impact the way you work going
forward.

Britain’s housing stock offers ‘worst value for
money’ of any advanced economy’, says report
A comparison of housing costs,
floorspace, quality and wider price
levels across countries reveals that
households in Britain are paying
more for less, and that our housing
stock offers the worst value for
money of any advanced economy,
according to analysis by the
Resolution Foundation.
The Foundation’s latest Housing
Outlook showed English homes
have less average floorspace per
person (38m 2 ) than many similar
countries, including the US (66m 2 ),
Germany (46m 2 ) and France (43m 2 ).
The UK’s housing stock is also
the oldest of any European country.
Older homes tend to be poorly
insulated, leading to higher energy
bills and a higher risk of damp, the
Foundation said. UK households
pay 57% more for the same
(quality-adjusted) housing as in
Austria, for example, and 36% more
than those in Canada. Housing in
New Zealand offers the second
worst value for money, followed by
houses in Australia and Ireland.
Adam Corlett, Principal
Economist at the Resolution
Foundation, said: “Britain’s housing
crisis is likely to be a big topic in
the election campaign, as parties
debate how to address high costs,
poor quality and low security issues
that so many households face.
Britain’s housing crisis is decades
in the making, with successive
governments failing to build enough
new homes and modernise our
existing stock. That now has to
change.”
Private housebuilding ‘springs to life’
The outlook for private
housebuilding has improved over
recent weeks, according to the
latest edition of the Glenigan
Construction Review.
The review has highlighted a
number of regional hotspots where
new housing work has been picking
up. The value of new housing
project starts in the West Midlands
rose to £854 million in the three
months to February – up 19% when
compared to the same period in the
previous year.
The East Midlands region also
saw an 8% increase in new housing
project starts.
Meanwhile, the new work
pipeline for housing shows signs
of improving in the North West.
Detailed planning approvals for
new housing work in the region
rose 13% to £1,974 million in the
three months to February, making
it the second most active region in
the country. Residential planning
approvals in the South West also
rose 27% in the period and were
worth £1,417 million.
Glenigan Marketing Director Ian
Bellamy said: “After tough times
in 2023, an upturn in new housing
output in January, and a series
of encouraging industry surveys
and announcements from major
housebuilders, point to better times
ahead for the sector, particularly in
the North and the Midlands. Recent
falls in mortgage rates and the
prospect of cuts in interest rates
has [also] given a lift to the overall
housing market.”
Insolvency hits
construction
companies
More than 4,300 construction
companies went out of business
between November 2022 and
October 2023, according to the
Insolvency Service – the highest
number since the financial crisis
of 2008-09.
Martin Vella, Managing
Director of contractor Pexhurst,
said: “The Covid pandemic, with
weaker consumer confidence,
inflation and interest rates,
has increased pressure on
all UK businesses, with the
construction industry being no
exception.”

Heat pump plans
delayed amid low
sales concerns
The Clean Heat Market Mechanism
(CHMM) is being delayed by a year
to 1 April 2025, to allow more time
for the heating industry to prepare.
The CHMM will introduce a rising
market standard for heat pump
sales as a proportion of fossil fuel
boiler sales, placing an obligation on
boiler manufacturers to meet targets
on their sales of heat pumps relative
to their sales of gas and oil boilers,
or face financial penalties.
The Department for Energy &
Net Zero (DESNZ) said it wanted to
allow industry more time to prepare
their businesses for the change,
and for more consumers to take up
heat pumps, before the scheme is
introduced.
The government says it remains
“fully focussed on supporting the
development of a heat pump market
of 600,000 installations per year by
2028, ensuring that heat pumps
become a mainstream consumer
solution alongside gas boilers, of
which approximately 1.8 million are
currently installed each year”.
However, recent figures from the
Heat Pump Association show that
just 55,000 heat pumps were sold
in the UK around 2022, meaning
an elevenfold increase would be
required by 2028 to meet the target.
A report from the National
Audit Office (NAO) has also noted
that the government’s flagship
Boiler Upgrade Scheme has
underperformed, installing just
18,900 heat pumps between May
2022 and December 2023. DESNZ
had previously said it expected
the scheme would deliver 50,000
installations by this point.
The NAO report said
“decarbonising home heating
represents one of the biggest
challenges to the government
achieving net zero”.
Heritage homes review ‘is a
positive step for homeowners’
A new energy efficiency drive for
heritage homes in the UK,
announced by the government in
early 2024, will review the barriers
homeowners face when looking to
future proof their homes while
protecting their heritage. The review
will also explore how these barriers
are affecting the UK’s work to
achieve net zero status by 2050.
With around 5.9 million properties
built before 1919 in the UK,
owners of heritage buildings face
difficult restrictions when looking
to upgrade them structurally. And
yet, with appropriate energy saving
measures, these homeowners could
save up to £428 per year on their
energy costs, estimates suggest.
The Residence Collection’s
Sales & Marketing Director, Sarah
Hitchings, said: “Trying to change
anything in a historic property or
conservation area is a long and
drawn-out process, which can be
immensely timely and costly.
“One of the biggest barriers is
that every local authority’s planning
department is different. With
this, homeowners and planning
authorities may not be aware of
the innovative products available
that can compassionately upgrade
period properties while maintaining
their original, historical beauty.
This makes it increasingly difficult
for homeowners to be granted
planning permission to upgrade their
properties.
“Reviewing these barriers
will mostly be positive for the
fenestration industry, as UPVC
windows offer a great thermal
performance and u-values for any
type of home, so owners of older
homes will really reap the benefits.
“Plus, this will allow installers to
add another sector to their business.
However, the review must be mindful
that there could be a skills gap, not
just in the fenestration industry, but
across the board when upgrading
period homes.
“As an industry, we must
continue to encourage highquality
installations in these types
of properties so we can preserve
these homes while being a part
of the solution to improve energy
efficiency.”

Second staircases should be fitted in tall buildings
The government has published new guidance to make it
clear that blocks of flats above 18m in height should be
served by a second independent staircase under
revisions to Approved Document B.
The new guidelines are expected to be introduced
in England from 30 September, 2026, as part of the
government’s efforts to improve fire safety by providing
additional escape routes in residential high-rise
buildings. There will be a 30-month transition period to
reduce the short-term impact on housing supply.
Announcing the new guidance, Minister for Housing
Lee Rowley said: “The change in guidance to include
two staircases for buildings over 18 metres provides
clarity and ensures both new and existing buildings
provide safe and secure homes for all residents.”
An impact assessment published by the Department
for Levelling Up, Housing and Communities (DLUHC)
estimated that compliance with the provisions would
cost £2.7 billion over the next 10 years.
DLUHC said: “Making provision for an independent
second staircase in tall buildings above 18m is part of
the post-Grenfell building safety programme. A second
staircase will provide additional capacity to reduce
congestion, support egress and facilitate additional
access for firefighting and rescue. Occupants will
benefit from an alternative means of escape if one route
is blocked or filled with smoke. A second staircase
will facilitate evacuation if a Stay Put recommendation
needs to be overridden. It will also help to synchronise
national standards by aligning to rules in Scotland.”

DELAYS, UNCERTAINTY AND A GENERAL
ELECTION BURDEN THE UK ENERGY MARKET
Rinnai’s Chris Goggin looks at
the current state of play in the
UK energy, heating and hot
water provision marketplace.
Commercial heating and hot water
provision sectors currently exist in a state
of uncertainty in relation to customer
costs, outside investment, future
direction and the implementation of
national legislation that encourages
decarbonisation. Further turbulence will
be exacerbated by the certainty of a
looming UK general election and a
possible change of government, which
could signal a redrafting of national
energy policy.
Over the past year the current UK
government and opposition parties have
reneged on several ecological pledges
and appear to have lost momentum in
implementing national decarbonisation.
Shifts in policy have created confusion
for investors inside the UK energy market
and, in the meantime, life goes on as the
population still requires heating and hot
water provision, through both new and
replacement systems. UK national
energy acquisition, property regulations
and UK gas boiler manufacture are all
areas of the UK energy market that have
experienced recent reversals in terms of
active or incoming legislation.
Aviva, one of the UK’s biggest insurance
company’s, was quoted in The Times as
saying: “The government increasingly
focuses on short-term energy security
over long-term sustainability.”
As European and American big business
have embraced large renewable
projects, UK political indecision, everrising
global energy costs and the
question of supply security has led to a
lack of investment within large-scale UK
renewable projects. In the same The
Times article, Aviva has said that “the
recent dilution in government net zero
targets is an even bigger challenge and
creates uncertainty”.
The Energy Transition Readiness Index
2023 is a measurement of a region’s
ability to transition towards net zero. It is
a report compiled for potential investors
to evaluate a country’s viability towards
profiteering from renewable electricity.
The latest report believes that investors
will only be attracted towards UK
projects if they can observe clear and
succinct governance as well as
regulatory stability. Presently, there is not
considered to be enough evidence of
either to entice outside capital
investment.
The UK government has had to offer
£800 million to support new offshore
wind farms as the amount of capital
incentives offered in the previous round
of CfD offshore wind auctions failed to
attract a single bid.
Concurrent with this is the situation
regarding the Minimum Energy Efficiency
Standard (MEES) regulations. These
ensure that all buildings have an Energy
Performance Certificate (EPC) with E as
its lowest rating. Further amendments
drafted in 2021 aimed for MEES to be
raised to D in 2025 and C in 2030.
This would have meant that landlords
who privately own and rent property
across the UK would have had to legally
meet energy efficiency standards to
continue renting to customers.
However, the UK government has
scrapped these plans as their
implementation would have meant extra
costs to both landlord and property
rental customer. A redrafting of MEES
regulations is expected and will likely
impose clean energy standards on
rented property.
Also, there is the ‘ban’ on gas boilers
being installed at off-grid sites, which
has been lengthened from 2026 to 2035.
The ‘boiler tax’ has also been delayed.
A potential new government later this
year could also introduce further
changes to the UK energy market by
way of a new direction in policy and
cost.
Specifiers, contractors, installers and UK
property owners should seek to work
with manufacturers of hot water and
heating products that can offer a wide
range of appliances in the variety of
energy vectors to produce low-carbon
solutions for all residential, industrial and
commercial properties. It is likely that the
UK will hold on to natural gas for the
moment while purposely manoeuvring
different energies and production into
play on a mass scale – be they wind,
solar, DME or BioLPG.

SPECIAL FEATURE
ACCUROOF: THE NEW NAME FOR
SIG DESIGN AND TECHNOLOGY
Trading Director Robert Edwards explains why SIG Design & Technology is
rebranding to AccuRoof, and what this means for its specifier-led customer base
and the wider construction industry.
Over the last decade, SIG
Design & Technology has
established itself as the
go-to roof design and
supply provider for both
newbuild and refurbishment projects,
including single ply, hot melt, liquid, slate,
hard metal roofing and cladding, as well
as green and blue roofing and biosolar
systems.
Central to our success has been our
ability to help specifiers deliver roofs
that are not only fit-for-purpose, but
also meet the required aesthetics,
are long lasting and sustainable. We
are constantly evolving our business
approach and customer offering, and
we recently decided to rebrand to
AccuRoof.
Accurate agnostic advice
The decision to rebrand has been
strongly influenced by the new Building
Safety Act and the Golden Thread.
We undertook market research with
key stakeholders, including architects,
surveyors, and contractors, to better
understand the areas they needed help
with. For most of them, it was assistance
with compliance and building legislation.
The SIG Design & Technology model
was already supporting this, but we felt
it was time to really push the envelope
and demonstrate our expertise within the
industry. This led to the AccuRoof name
and branding, which stands for accurate
agnostic roofing advice.
AccuRoof is a system agnostic roofing
specification and technical support
service for architects, specifiers and
contractors. We provide a complete
and impartial service, which covers flat
roofs, pitched roofs, green and blue
roofs, solar, biosolar, and hard metal
roofing and cladding. We provide expert,
competent guidance that is up to date
with current legislation, including British
Standards and the Building Safety Act.
As a distributor (part of SIG Roofing, a
part of FTSE-350 listed SIG Plc) we have
numerous product lines from a wide
range of manufacturers, enabling us to
offer the best roofing solution for any
given project. The advice part is fairly
self-explanatory: that’s what we are there
to do; to be experts within the roofing
industry.

specifications that meet a project’s
budget requirements. Parallel to this we

specifications that meet a project’s
budget requirements. Parallel to this we
have emerged as a dedicated roofing
consultant to specifiers themselves as
roofing system requirements become
more complex and they need our
specialist advice. We’ve taken that role
for over 10 years now.
The introduction of Gateway two under
the Building Safety Act means that the
way buildings and roofing systems are
procured may change. There will be
more collaboration, and Design & Build
may even become a thing of the past.
AccuRoof aims to be at the forefront
of this change, assisting architects,
surveyors and contractors with key
roofing decisions from the outset of
construction projects. This means
offering design and technical advice
on integrated roofing systems, while
adhering to building regulations and
other legislative requirements.
Because we are a distributor we have
access to an incredibly wide range of
products, so our roofing specifications
always fit the project, rather than the
other way around. This enables us
to advise on the best product for a
particular roofing solution, considering
CCPI, accreditations and testing, and
regulatory compliance, among many
other factors.
AccuRoof provides a wide range of
services free of charge, including design
liability (if required), detailing advice, full
NBS specifications, wind uplift, U-value
and drainage calculations, guidance on
renewable and specialist products that
assist with common design issues, such
as creating falls on flat roofs or providing
for energy production.
Added to this, we offer ease and
reliability of product distribution coupled
with a competent subcontractor network
under our AccuRoof
Contractor Installer
Scheme (ACIS).
Tailored services
Any organisation
that rebrands has to
have taken a long
hard look at how
it works and who
it supports. This
exercise has helped
us clarify how we
support the variety
of professionals
designing,
constructing and
looking after built assets. The uniting
theme is that we help the sector
deliver better performing roofing
solutions.
Alongside supporting specifiers, we
partner with main contractors on major
projects to offer them an end-to-end
service for their roofing packages,
ensuring they can always receive
dedicated technical support and helping
them work more collaboratively with their
supply chain.
Through ACIS we support roofing
contractors access training and
technical support to ensure they install
our products effectively and enable us
to provide warranties. In the education
sector we are a supply chain partner
on Department for Education projects,
helping education clients meet their
biodiversity net gain and net zero
challenges. We also provide a flat roof
replacement, planned maintenance,
funding and estate management
strategy support for multi academy
trusts.
Get specialists in early

can examine their designs and eliminate
potential issues, such as door thresholds
and parapets on flat roofs, or structural
issues relating to green and blue roofs.
Equally importantly, AccuRoof can assist
with fundamental decisions relating
to cost, aesthetics, compliance, and
warranties – all of which should be
carefully considered at the outset.
Adherence to regulatory, standards and
third party compliance is one of the
biggest challenges, so it’s important
that specifiers have confidence in the
competency of their design and supply
chain partners. AccuRoof expertise
in this area, coupled with its ability to
supply a wide range of products that
can satisfy the demands of both the
roof and the client make it a potent
force – especially where there is early
engagement with the specifier.
We’re excited about the future of
AccuRoof as a unique service for
specifiers. In the coming months we will
introduce new CPDs and launch several
new products, such as a lightweight,
non-penetrative, flat panel solar
roofing system, and a new TPE roofing
membrane.

SPECIAL FEATURE
A SHIFT IN THE LANDSCAPE
The Building Safety Act has been introduced to transform the way our buildings are
designed, constructed and maintained. Justin Pitman, Sales Director for Proteus
Waterproofing, explores what this means for specifiers.
The Grenfell Tower fire tragedy in
2017 sent shockwaves through
the UK, exposing widespread
safety failings in the construction
industry. In response, the Building
Safety Act 2022 has ushered in a wave
of changes. One crucial aspect of this
reform is the emphasis on protecting
specifications. But what does this mean
for manufacturers and specifiers?
The Act introduces a multi-faceted
approach to building safety, with several
key changes impacting the market. A
new regulatory framework means that a
Building Safety Regulator (BSR) will now
oversee all building work, with stricter
oversight for higher-risk buildings.
The Act clearly defines roles and
responsibilities for stakeholders such
as manufacturers, developers and
building owners, ensuring accountability
throughout the building lifecycle.
This involves the implementation of a
rigorous, stage-gated approval process
for higher-risk buildings, ensuring
compliance with safety standards at
each stage, supported by a ‘golden
thread’ of information capturing crucial
building data throughout the building’s
lifespan, improving transparency and
traceability.
There is also now more emphasis on
strict requirements for the competence
and accreditation of construction
professionals and manufacturers, in a
move to raise industry standards.
One significant aspect of the Act is
the increased emphasis on protecting
specifications. This means ensuring
that the materials specified are the
ones actually used in construction,
preventing substitution with inferior or
non-compliant alternatives. Several
provisions such as product certification
encourage standardised product
testing, with certification schemes to
verify performance and compliance with
building regulations.
Traceability and Chain of Custody
is also paramount. This requires
robust measures to track materials
throughout the supply chain,
preventing the use of counterfeit or
unauthorised products. There is also
a requirement to share key product
information between manufacturers,
specifiers and building owners at every
stage. At Proteus Waterproofing we
already hold BBA certifications and
other key accreditations, so we can
demonstrate compliance with these
stricter regulations. We have further
implemented a robust supply chain
management and sharing product
information system, which is helping
to build trust and confidence among
specifiers and building owners.
For specifiers, access to standardised
product data and certification schemes
allows them to make informed
decisions based on demonstrably safe
and compliant materials. Protecting
specifications minimises the risk that
non-compliant materials are used,
reducing potential legal and safety
liabilities. Confidence in material
performance and compliance further
contributes to a safer, more durable and
successful building project.
Robust traceability also helps specifiers
demonstrate they used the intended
materials, mitigating potential liability
concerns. The Act provides stronger
legal protection for specifiers who have
fulfilled their duty to specify compliant
materials. An increased onus on
manufacturers for product safety and
information sharing can also reduce
burdens and liability risks for specifiers.
Building trust and open communication
with manufacturers can facilitate access
to technical expertise and support
throughout the specification and
procurement process. We at Proteus
provide a full design package to help
architects at every stage of the project.
Staying updated on complex regulations
and navigating new approval processes
can be time-consuming for specifiers
with limited resources. Effectively using
and integrating product information into
project documentation and specifications
also requires additional effort and
expertise, something we can help with.
While the Building Safety Act is a
step towards a safer future for UK
buildings, its full impact is still unfolding.
Its success will depend on several
factors, such as the BSR’s approach to
enforcement and guidance, which will be
crucial in ensuring consistent application
of the regulations. Open communication
and data sharing between all
stakeholders will also be essential for
building trust and transparency.
The Act is an opportunity for the industry
to embrace higher standards and
safer, more sustainable buildings. While
challenges exist, manufacturers and
specifiers who collaborate and adapt
proactively can navigate the evolving
landscape and emerge as leaders in this
new era of building safety.

BALANCING CONSERVATION WITH
REFURBISHMENT
B&K Structures was involved in the reimagining of a former timber yard in the
famous Pimlico Road Design District. Specify & Build reports.
Newson’s Yard is a highprofile
new design hub
featuring top-end retail
outlets and eateries, located
in a meticulously refurbished
and reimagined former timber yard set
amidst the famous Pimlico Road Design
District.
Created mainly as a residential
extension to Belgravia, the Pimlico
district of South-West London is known
for its garden squares and Regency
architecture, being first designated
as a conservation area in 1968. As
befits a former timber yard, timber
was a key material for this imaginative
refurbishment scheme, and B&K
Structures (BKS) – a leading exponent
of mass timber and structural steel
packages – was instrumental in its
delivery.
Newson’s Yard has been developed
by Grosvenor, with Stiff + Trevillion as
architect and Heyne Tillett Steel (HTS)
appointed as structural engineer. BKS
provided the offsite-manufactured,
hybrid steel and engineered timber
package, including the use of CLT
panels, which formed part of the
new internal structure and created
an extensive mezzanine level, which
stands at the heart of the development’s
identity, as well as its commercial
success.
Design expertise helped address the
technical challenges associated with the
heavy refurbishment work of Newson’s
Yard. Rob Mills of HTS explains: “We
were involved in a very detailed survey of
the building prior to beginning the design
work, which showed the old timbers
were actually in quite good condition,
but the task of incorporating them, and
the retained brickwork, into the new
structure was extremely complex.
“Part of the reason we were able to
employ a CLT solution was its inherent
fire resistance. Each of the units has
its own means of escape so we were
only required to achieve 30 minutes
protection across the mezzanine:

AND RETAIL
Sustainability was a heavily emphasised
requirement for the project. As such, the
developers opted for offsite-manufactured mass
timber due to its sustainability benefits and wellrecognised
structural capabilities.
The supply chain for the Newson’s
Yard project, including BKS, used
interoperable Industry 3D modelling to
identify clashes and understand how the
CLT had to be installed before optimised
production began. Collaboration
between all parties on the project was
facilitated by the digital design software,
making time and cost savings and
offering the most up-to-date information
available.
which we could justify with the
charring characteristic of the CLT; and
therefore, installing fire sprinklers was
unnecessary.”
Michael Polack, Technical Manager
at B&K Structures, adds: “BKHS
designed the timber and steel
connections. The cantilevering internal
balconies, and restrictions on loading
of the existing masonry piers, led to
the challenge of high moments on
the CLT to steel connections. This
challenge was overcome by using
shot-fired connections which optimised
constructability on site.”
A focus on sustainability
Sustainability was a heavily emphasised
requirement for the project. As such,
the developers opted for offsitemanufactured
mass timber due to
its sustainability benefits and wellrecognised
structural capabilities.
However, the loadbearing requirements
sometimes require timber to be married
with stronger construction materials –
primarily steel – to match the project’s
specific demands. In the case of
Newson’s Yard, a hybrid offsite solution
in the form of structural steelwork
supporting 700m 2 of CLT floor slabs
and the retained frame of the Victorian
building proved the ideal combination.
Just as important was the conservation
of the timber yard’s aesthetic, meaning
that a totally bespoke design was
required. The inclusion of CLT panels
for the floor slabs brought a number of
aesthetic benefits to the project, with the
new tenants choosing to keep the visual
appeal of exposed timber, rather than
lining the units. In fact, the designers
specified ‘Industrial Visual’ grade CLT
slabs, which means the CLT is of a high
enough visual quality to be left exposed,
suiting the ambience of the former timber
yard and also offering a long, robust
working lifetime.
The use of a prefabricated mass timber
system had inherent time-saving benefits
that cut onsite prelims and supervision
costs by 20%. It also reduced overall
construction time by 25 to 30%
compared to traditional construction
methods for this contract’s build phase.
Due to the precision-cut nature of the
CLT, defects and snagging – often
prevalent in traditional construction –
was minimised, helping to increase the
reliability of the handover date.
BKS Operations Manager, Craig
Robinson, says: “From design to
manufacturing, transportation and onsite
installation, the team used the latest
digital tools collaboratively to ensure
the project’s speedy and accurate
construction. Prefabricated timber
panels meant that all elements and
connections were able to be fitted offsite
and erected very quickly.”

INNOVATIVE INSTALL CREATES
STYLISH SPACE
Forbo Flooring Systems’ Allura Luxury Vinyl Tile range was specified by design and fit out
company, Oktra, to transform an office building into a stylish and modern workspace.
Oktra was recruited by Akoya and
Brunswick Property Partners to
repurpose an office building and
create a vibrant and attractive space for
young professionals and entrepreneurs
to work in. Formally known as Knollys
and Stephenson House, the building
will be rebranded as Mosaic East, a
refurbishment of one of East Croydon’s
most iconic office developments.
Typically, carpet tiles or exposed raised
access flooring are the go-to solution in
these scenarios. However, a premium
design was required for this project, so
Oktra opted for something different, as
Danielle La Porte, Designer at Oktra
explains: “Akoya wanted to create a
range of category A office suites that
would be memorable to tenants, while
also meeting sustainability requirements.
We specified Forbo’s Allura Flex LVT,
which is available in range of elegant
colourways and wood effect designs.
“We decorated some of the category A
suites in a light pink colour with linear
LED lighting, and others in a light sage
green colour. To complement the colour
palettes, we chose Allura Flex LVT in the
Light Honey Oak shade. We then asked
flooring contractors The Commercial
Flooring Company to install the planks in
a beautiful herringbone pattern.”
However, appearance wasn’t the
only area of concern, with Akoya
also conscious of the sustainability
requirements. Danielle says: “The
aesthetics of the flooring weren’t the
only thing we had to keep in mind; we
also had to ensure that whatever floor
covering we specified would meet
Akoya’s sustainability aims. It was for
this reason that we specified Forbo’s
Allura Flex, as it can be easily installed
adhesive free, using IOBAC MagTabs.”
IOBAC’s MagTabs provide a twodimensional
hold, with one side being
magnetic and the other a dry-tack
adhesive. This means they can be
easily magnetised onto metal-raised
access flooring, like those at Mosaic
East, negating the need for traditional
adhesives.

Ian Spreadborough, Founder and
Director at IOBAC, explains: “Our
MagTabs essentially allow flooring
contractors to quickly place floor
coverings down onto raised access
flooring, without damaging the substrate
or the flooring itself. The flooring is
securely fitted but can then be lifted back
up to be reused elsewhere, or replaced
by another floor covering further down
the line.
“Oktra had used our MagTabs on a
previous project and was keen to use
the product again. Brunswick, which
owns the raised access flooring itself,
was keen to maintain the condition of
its asset, so the tabs served a double
purpose, protecting both a heavy carbon
embodied asset and Forbo’s floor
coverings.”
Jon Cochrane, Director – Asset
Management & Sustainability at
Brunswick Property Partners, adds:
“Cleaning adhesive residue off subfloors
in between leases is often messy,
expensive and time-consuming. In some
cases, the raised access floor panels
are so badly contaminated that they
must be completely replaced, something
which isn’t sustainable, environmentally
or financially. Using IOBAC MagTabs
removes this issue completely and
means the raised access flooring, is
protected and kept damage-free for
longer-term usage.”
Daniel Hassan, Operations Manager
at The Commercial Flooring Company,
says: “Thanks to IOBAC’s MagTabs it
took a team of three fitters around five
days to install 900m 2 of flooring in a
herringbone pattern, which is challenging
to install and would have taken much
longer to do through traditional methods.
This provided a great time saving and
allowed the other trades to work around
us while we fitted the flooring.”
The time saved during the installation
stage meant the project as a whole was
completed in just 10 weeks, a quick
turnaround for such a large job.

ROOFLIGHTS INSTALLED IN GRADE II* LISTED BIRMINGHAM MUSEUM & ART GALLERY
Whitesales has replaced the original timber rooflights in the
Grade II* listed Birmingham Museum & Art Gallery with new
bespoke aluminium rooflights, ready for the reopening of
museum during 2024.
Built in 1885, the Birmingham Museum & Art Gallery
has an unrivalled 2,000 piece Pre-Raphaelite collection.
However, it closed in November 2022 for essential
maintenance which has included electrical work, upgrading
of the heating, lift replacement and roof repairs.
The new rooflights were a key element, so the challenge
for Whitesales was to supply and install high performance,
energy efficient replacements for the timber originals which
satisfied the constraints of the Grade II* listing and met
the requirements of the City Council’s conservation office.
The solution included one bespoke Whitesales Monopitch
2,610mm x 1,260mm rooflight with vertical front face and
sides set at 350mm and two bespoke lantern rooflights
with sides set at 440mm and 450mm, all finished in an
anthracite grey on the exterior and white on the interior and
all CWCT TN92 Class 2 non-fragile to ensure the safety of
anyone walking on the roof.
Whitesales worked closely with contractors ISG
throughout the design and specification process. They
visited the site for a survey, attended design meetings
and delivered a sample to the site so that everyone on
the client team was happy with what was being supplied
in terms of both performance and aesthetics. They also
ensured that the rooflights were all fabricated and safely
delivered to site in manageable-sized elements to take
into account the difficult access to the city centre site.
For ISG’s Trainee Construction Manager Ryan Linnecor,
Whitesales impressed with their knowledge and experience
on heritage schemes. He commented: “Whitesales had a
clear understanding of the Grade II* listed scheme and
the constraints that presented. They impressed us once
again with their approach on how to undertake the work
sympathetically and the finished installation is of a very
high quality.”
The clients at the Museum have already commented on
how the new rooflights are bringing new natural light into
previously dull areas of the building, something which will
be appreciated by visitors when the Museum and Gallery
starts to reopen this year.

ZENTIA TO DELIVER FIT OUT AT DOVE VALLEY PARK
Located at the centre of one of the UK’s most important
manufacturing areas, Dove Valley Park is a 200-acre
industrial site that currently houses occupiers such as JCB,
Marstons and Rolls Royce, with further planning consent
granted for up to 2.3 million sq ft of infrastructure and
services.
Ceiling solutions provider Zentia has been asked to
deliver a fit-out for a newbuild office within the industrial
estate. The project scope includes meeting rooms and
bathrooms with a classic office visual, while incorporating
a burst of colour in the breakout space and meeting rooms.
The challenge was to execute a visually pleasing design
that complemented the newbuild while meeting the client’s
specific colour and acoustic requirements.
The project is in the installation phase, with main
contractor Roe Developments overseeing the construction
and East Midland Ceilings responsible for the ceiling
installation.
Zentia opted for Aruba square tiles throughout the
office space. They were installed in the meeting room
in two different shades of grey, while the bathrooms
featured Aruba hH tiles, ensuring a visually clean and
bright ambience but with enhanced humidity resistance.
The choice of tiles was driven by their high acoustic
performance, providing a conducive environment for
meetings and workspaces. The availability of colour
variations also appealed to the client and allowed Zentia
to create a seamless transition between the standard white
tiles and the specified shades of grey.
Installer Barry Deane, Director at East Midlands Ceilings,
said: “It’s always exciting when the customer wants a
change from the standard types of suspended ceiling
designs. It made the project extremely interesting to be
involved with, and the Aruba coloured tiles look amazing,
giving a modern and visual twist over the standard install.
The quality of the materials was also fantastic, with
everything being manufactured and delivered to suit the
project requirements perfectly.”

IS HYDROGEN A
SUSTAINABLE CHOICE?
Pete Seddon, Technical Manager at Rinnai, explores whether hydrogen is a safe
and sustainable choice for commercial heating and domestic hot water projects.
As global economies continue to
identify and incorporate clean
and sustainable energies into
respective national options, hydrogen
has emerged as a potential source
of energy capable of decarbonising
and delivering power to domestic and
commercial applications.
Despite the Whitby and Redcar
Hydrogen Village Trial cancellations, the
UK government has taken a strategic
policy decision to support hydrogen gas
blending of up to 20%.
To achieve the lowest possible carbon
outputs on a national, continental and
global scale there will, inevitably, be
significant changes to infrastructure
– in areas such as generation and
distribution. These changes will take
decades to implement. What is also
inevitable is that shared technology will
end a reliance on the mass production
of a major and singular energy source.
Hydrogen, along with all other fuels,
could play a major role.
Hydrogen has some specific advantages
over fossil fuels. It produces zero carbon
emissions and can be produced using
renewable resources such as wind and
solar power. Hydrogen usage can also
assist in creating healthier local air quality
and in the reduction of the UK’s reliance
on fossil fuels.
However, there are some real and
perceived safety issues surrounding
hydrogen’s mass deployment. Hydrogen
is highly flammable and requires careful
handling and storage, as do all domestic
and commercially used gases worldwide.
Additionally, the construction of hydrogen
infrastructure is currently incomplete
and could demand existing in-building
pipework to be connected to existing
commercial heating systems, meaning
hydrogen may not be accessible or costeffective
for every building.
Understanding the safety of
hydrogen
There are numerous reports that both
support safety risks and advantages
associated with hydrogen heating.
The UK government will decide on the
feasibility of hydrogen heating in 2026,
while the Health and Safety Executive
(HSE) will provide an authoritative and
impartial report on all safety aspects
concerning 100% hydrogen distribution
across Great Britain.
The support provided by the HSE will
feed into Government policy decisions
in 2026 based upon the HSE’s 2023 call
for evidence on hydrogen heating. The
HSE will also work alongside OFGEM,
gas operators and the Department for
Energy Security and Net Zero regarding
potential neighbourhood hydrogen
heating trials and evidence supporting
hydrogen usage across other regions.
The primary focus of the HSE is to
ensure that network operators possess a
full understanding of all risks associated
with hydrogen heating, storage and
distribution. The HSE has also set up a
future hydrogen regulatory workstream
to assess the suitability of HSE enforced
regulations. This work will consider
the regulatory and legislative changes
required to enable a potential larger roll
out of 100% hydrogen for heating.
The HSE will also develop options for
Hydrogen is highly
flammable and
requires careful
handling and storage,
as do all domestic and
commercially used
gases worldwide.
any necessary amendments to the
health and safety regulatory frameworks.
This will contribute to potential policy
options for future safety regulation in the
final quarter of 2024, followed by written
advice to the Department for Energy
Security and Net Zero in March 2025
ahead of the final decision on hydrogen
for heating in 2026. Therefore, if greater
volumes of hydrogen do enter the UK
gas distribution network, it will only be
after a complete safety review.
Hydrogen projects being implemented
in other countries demonstrate that
hydrogen heating is not just a theoretical
concept, but a practical and viable
solution for reducing carbon emissions
and transitioning to a more sustainable
energy system. In The Netherlands, the
HyStock initiative aims to produce and
store hydrogen using excess renewable
energy. Stored hydrogen is used to
provide heat and power during periods
of high demand, reducing national
reliance on fossil fuels.
Hydrogen heating has the potential to
be a safe and sustainable energy option,
but a final decision will only be made
after a robust and detailed safety review
is presented alongside a comprehensive
structure of regulatory framework.
Hydrogen offers environmental benefits
such as zero carbon emissions and
renewable sustainability that reduces
fossil fuel utilisation, however safety
considerations and limited infrastructure
are areas that require further
development and study.

DOKA FORMWORK ESSENTIAL TO THE DELIVERY OF HIGH-PROFILE SCOTTISH
HARBOUR EXTENSION
Doka has supplied the specialist formwork and technical
support to facilitate a multimillion pound expansion of South
Harbour in Aberdeen, the largest marine infrastructure
project in Trust port history.
The company worked in conjunction with contractor
Beattie FRC on the harbour’s North Breakwater Crown Wall
and surrounding main quay works.The overall aim of the
development was to expand and diversify its use, allowing
more vessels to dock and significantly broaden trade
opportunities.
The 620m crown wall’s concrete construction was the
result of detailed consultation between Doka and Beattie
FRC. The contractor specified a two-pour solution in height
involving 10m lengths boxes for what was an extremely
large scale programme. With inclement weather a potential
hinderance, the need to meet the client’s strict deadline was
of the utmost importance.
The Framax Xlife and Eurex 60 550 plumbing struts,
MF240 platforms, WS10 Platforms from Doka were key to
the safe, timely completion of the crown wall pours, which
varied from 3m to 5.5m in height. The system’s rapidforming
capability was enabled by its optimised panel sizes,
which worked perfectly for the new desired pour heights.
Furthermore, its forming times are kept to a minimum by
widely-spaced form-ties of up to 1.35m apart. With the
Framax Xlife unit, accuracy is not compromised for speed,
with all connectors and accessories fitting seamlessly by the
site team.
On the crown wall quayside, the Doka MF240 climbing
formwork optimised any on-site works as these were all
assembled offsite by Doka in Sheffield. It meant that when
they arrived at the site, they were almost immediately placed
on the wall. The fully edge-protected, 2.40m-wide working
platform enabled engineers regular, controlled access to the
crown wall during its construction, as well as being able to
plumb and align the Framax.
Similarly, this process was duplicated for the WS10
platforms for the North Sea side of the wall. On this side
of the wall the top pour contained a cope that had to be
formed and supported. This helped inform the WS10
platforms’ design. The cope’s load was transferred from the
T7 spindles back to the platform and cast in wall anchors.
This further intricate detail was easily accommodated by the
range of quality Doka systems.
The South Harbour’s expansion has achieved a number
of beneficial outcomes. These include increasing the
harbour’s water depth to 15m; enabled the berthing of
300m vessels; expanding laydown area to 125,000m 2 and
widening channel access to 165m.

HOTELS AND LEISURE
VICTORIAN MANSION
TRANSFORMED INTO CARBON-
NEUTRAL EVENT VENUE
Bronllys Hall in Powys, Wales is on a journey to become a sustainable events venue heated
by an innovative system using vegetable oil, solar, wind, batteries – and a Megaflo cylinder.
AVictorian mansion in Powys
is being transformed into a
sustainable events venue using
a combination of renewable and lowcarbon
technologies, including a new
hydrogenated vegetable oil (HVO) boiler
working alongside a highly efficient
Megaflo 1,000-litre cylinder. It’s believed
to be the first heating solution of its kind
fitted into a UK events venue.
Work underway at Bronllys Hall, parts
of which date back to the 18 th and
16 th centuries, will create 40 ensuite
bedrooms and various entertainment
areas – and a lot of space to heat. It
was important to find a boiler solution
that was suitable for the job, so Hughes
Architects, the conservation architecture
specialists managing the Bronllys
project, teamed up with Suffolk-based
Hounsfield Boilers.
The systems integrators for Bronllys
Hall, working with a local plumbing
company, connected Hounsfield’s
HVO boiler technology into a thermal
storage system provided by Baxi.
Manufactured in the UK, the Megaflo
1,000-litre cylinder is highly insulated
to ensure low heat losses, constructed
of duplex stainless steel for longevity,
and maintenance-free with no sacrificial
anodes.
Richard Whittington, Technical Sales
Manager at Baxi, says: “The very low
heat losses of our Megaflo hot water
cylinders and their reduced carbon
footprint dovetail perfectly with the
carbon-neutral aims of this project, as
well as meeting the requirements for a
long-term, low-maintenance solution.
We are extremely proud to be playing a
part in this ground-breaking sustainable
events venue.”
This is a key step forward in the major
renovation project at Bronllys, which
aims to transform the deteriorated
structure into a five-star events venue
that operates sustainably and uses only
renewable energy sources.
Doug Hughes, Principal Architect
and Managing Director of mid Walesbased
Hughes Architects adds: “Along
with our other partners, Hounsfield’s
technology and Oil4Wales’ logistics
enable HVO heating to work at scale
with high availability. HVO is a highly
effective way to solve the difficult issue
of decarbonising heating, with options
to scale for the future and deliver on our
collective commitment to sustainability.
This approach not only gives incredible
projects like this a competitive edge
through delinking from carbon-intensive
fossil fuels and their price swings,
but also adds further to its core eco
credentials.”
Andrew Hounsfield, Founder of
Hounsfield Boilers, says: “We have been
producing HVO-ready boilers for a few
years now, with a focus on long life
through quality, British-made parts. We
need to decarbonise and HVO provides
a sustainable green energy source.
Adopting this fuel more widely will
reduce our reliance on foreign fuel.”
Although HVO is produced from 100%
sustainable resources, is low carbon
and reduces emissions, it is still being
taxed as road diesel, due to the way it
is distilled, and that attracts a 57.95ppl
duty as a result.
Sally Williams from Oil4Wales says: “The
cost of HVO is currently about twice the
price of heating oil. If the government
were to reduce the tax this would drive
demand and enable the industry to make
economies of scale, bring the price
down, and boost uptake of HVO as a
low-carbon heating fuel. Converting from
Kerosene to HVO can be very cheap and
easy.”
Hughes continues: “Bronllys Hall is an
older historic building that we, with the
owners and skilled local tradesmen
have sought to conserve and safeguard
its history, while embracing the best of
British technology to delivery sustainable
outcomes and efficient operation.
“We also work closely with our partners
to ensure the technologies we use
integrate effectively; HVO for heating,
sophisticated battery management
systems for long life and British Solar
panels, along with other innovative
technologies and partnerships to be
announced over the next few months
that when fully integrated will deliver fully
on our carbon neutral ambitions.”

HOTELS AND LEISURE
DESIGNING LUXURY HOTEL
BATHROOMS
Sanipex Group’s Specification and Design Manager Ashley Sinclair explores what
makes a good hotel bathroom design, and the questions specifiers need to ask at
the beginning of a project.
What makes a good hotel
bathroom design?
Is it all down to its
function and practical
elements that make
cleaning simple and keep downtime to a
minimum? What about guest comfort?
And, with homeowners increasingly
taking influence for their own bathrooms
from their hotel stays, how can hotel
designers and specifiers raise the levels
of luxury even further to really inspire
their guests?
Hotel bathroom trends are constantly
evolving as hoteliers seek to carve
out a unique identity for their brand,
particularly in the luxury sector. The
quality and amenities of the bathroom
have long been considered an important
indicator of a hotel’s rating and, with the
current consumer preoccupation with
wellness, a hotel room that comes with
a luxurious spa-like bathroom is more
important than ever to boost customer
satisfaction scores.
A luxurious hotel bathroom designed
to promote wellbeing is increasingly
becoming an essential expectation for
sophisticated travellers. Must-haves
include freestanding or oversized
bathtubs, invigorating showers and
lighting that can be easily adjusted to
suit the mood. Biophilic design principles
add to the upscale ambience, bringing
the outdoors in with carefully curated
organic materials, natural textures and
a relaxing colour palette inspired by the
local environment.
Whatever the design aesthetic and however
striking the visual impact, ensuring optimal
functionality is the critical element that
ultimately determines the success of a project.
Functionality is one of the cornerstones that
interior design is built upon.
A new design twist is to blur the
boundaries between living, sleeping
and washroom spaces to promote an
enhanced sense of flow. The clever use
of sliding panels, doors and glass then
allows guests to close off the bathroom
as and when they require privacy.
Whatever the design aesthetic and
however striking the visual impact,
ensuring optimal functionality is
the critical element that ultimately
determines the success of a project.
Functionality is one of the cornerstones
that interior design is built upon and,
if not adhered to, may well have a
negative impact on budgets, delivery
timeframes and, ultimately, occupancy
rates and revenues. Meeting hotel design
regulations, as well as complying with
health and safety measures, offers peace
of mind to travellers, with minimum
standards needing to be met to achieve
set star statuses.
A balance of form and function
Grab bars are not always the most
attractive of bathroom accessories,

Located on the
banks of the River
Thames, the Vintry &
Mercer Hotel is steeped in
tradition and brought to life
with contemporary styling.
Bagnodesign was chosen to
supply high-quality brassware,
sanitaryware and accessories
for the hotel’s 92 tailored rooms
and suites. The turquoise tiled
bathrooms add to the charming
mix of old and new with a deep
bathtub and rainfall shower
for the discerned traveller.
Bagnodesign’s luxurious
brassware, sanitaryware and

functionality, while blending
in with the hotel’s unique design concept. The deep freestanding bathtub has a pull-out shower and handy
drinks ledge, promises a relaxing reprieve from the bustling city.
HOTELS AND LEISURE
Thankfully, contemporary designers
understand the need for aesthetically
pleasing options, the result being a
range of modern designs that will work
harmoniously with the overall bathroom
aesthetic. For larger projects, grab
bars can be custom plated to match
the overall bathroom finish, which is
particularly applicable for more unique
finishes such as Brushed Bronze and
Matt Black.
One benefit of choosing a bathtub in
modern composite stone, for example,
is that a grab rail can be integrated into
the bathtub design – by cutting it into
the composite itself – to allow safety
standards to be met without distracting
from the aesthetic appeal.
There are many examples among the
Sanipex Group portfolio of hotel projects
where form has met function due to the
careful specification of sanitaryware,
brassware and fittings.
One instance is the exclusive Kudadoo
private island resort, which has an
intimate boutique feel with its 15
stunning one- and two-bedroom, selfcontained,
over-water villas. Blending
authentic organic materials and textures
with luxurious finishes, each bathroom is
a peaceful sanctuary designed to invoke
the ultimate in wellbeing.
Acting as the focal point of each
spacious en-suite, the sleek lines of the
freestanding bathtub work in perfect
harmony with the overall biophilic
design aesthetic that comes through
in the raw wood finishes of the walls
and floor, and the artfully decorative
handicrafts. Specified baths were crafted
from Bagnotec and Bagnoquartz. Both
comprise of specialised compounds of
natural minerals and pure blended stone,
resulting in a velvet-textured finish. Each
Matt-White bathtub is custom-made to
fit the exact design specifications for the
space.
Meanwhile, organic simplicity meets
sleek styling in the 430 ensuite
bathrooms of Jumeirah Al Naseem, a
five-star hotel in Dubai. Natural organic
textures blend beautifully with the
wood finishes, marble surfaces and
subtly shimmering mosaic tiles layered
throughout the space.
Taking centre stage in the bathroom, a
custom-made freestanding oval bathtub
in enamelled steel with the Duo Comfort
invites guests in for a relaxing soak.
The space also functions as a wetroom
and features a separate walk-in shower.
Flexibility is key with edge-to-edge
louvred doors enabling guests to have
the room as either one open-plan space,
or in the more traditional configuration,
as and when they wish.
Overall, hotel bathroom trends reflect
a growing emphasis on wellness and
luxury. Examples like those described
here demonstrate the successful fusion
of form and function, creating tranquil
sanctuaries that enhance the overall
guest experience.

LONDON’S LAFAYETTE NIGHTCLUB - NOW WITH SANICUBIC
The Lafayette nightclub is a musician-friendly club in the
heart of Kings Cross, London, which first opened its doors
in early 2020 before being swiftly closed due to lockdown.
Since successfully re-opening in 2021 it has become wellknown
on the UK music scene, hosting hundreds of music
shows and performances from household name bands.
When the 600-capacity venue was refurbished, a kitchen
was installed in the basement and WCs sited on the floor
above, along with a cleaner’s cupboard. All waste water
from these areas formerly drained into a bespoke pumping
system in the corner of the pot wash area, which pumped
the waste up to ground level and away to the main drain.
However, a soil inlet that was slightly submerged into the
lower section of the chamber was preventing waste water
from completely draining into the pit, while a 100mm inlet
pipe was too close to one of the submersible pumps in
the pit, preventing it from eliminating all paper waste. This
caused clogging and blockages, ultimately becoming a
general inconvenience to an otherwise excellent venue.
Surrey-based PumpServ was approached by the club’s
management to evaluate the issue and suggest a solution.
One option was to lower the chamber floor, but this would
involve breaking out the concrete oversite.
With concerns about the proximity of the Regent Canal
and potential ground water ingress, PumpServ offered an
alternative solution. After a call to the technical team at
Saniflo and a subsequent site inspection, the floorstanding
Sanicubic 2 Pro lifting station was recommended.
David Knight, Business Development Manager for
PumpServ says: “The Saniflo Sanicubic Pro 2 has taken
away the headache of blocked facilities for the Lafayette
nightclub. The position of the two submersible pumps was
restricting black waste and paper waste flow and these were
building up at the point of entry.
“Occasionally, the inflow would surcharge back to the
kitchen floor drains causing a flood. With twin pumps – for
failsafe operation – the sealed unit simply slotted into the
space without any need for civils work, eliminating the risk
of overflow. The 110mm inlets, positioned at 140mm (floor
height to centre of inlet), enabled a better fall for the swift
discharge of incoming waste.”
The Saniflo commercial range has been designed for
practical situations where waste needs to be lifted away
safely and efficiently and the installation of this Sanicubic 2
Pro in the Lafayette nightclub perfectly illustrates the use for
a Saniflo lifting station.

ROBUST FLOORING FOR HAMPSHIRE MILITARY TRAINING FACILITY
When designing a gym for free weights and functional
training in a demanding environment, it’s important to
choose a product that has strength, flexibility and longevity.
CMS Danskin was approached by a respected gym fit out
company to assist with a strength and conditioning facility in
a tri-service military base in Hampshire. The company has
worked with CMS Danskin on gym products for many years
and approached it to supply flooring for the entire 332m2
facility at Worthy Down, home of the new Defence College
of Logistics, Policing and Administration, which provides a
single site for training key support roles for the Royal Navy,
Army and Royal Airforce.
Facilities for military training often have a number of
specific requirements. In this case the requirements were a
single flooring solution suitable for free weights, providing
a heavy-duty dropping zone, plus user comfort during
functional training and while using a variety of equipment.
The facility needed a particularly robust solution able to
meet the high standards expected by a military client, and
the entire facility needed to be able to be rapidly broken
down and moved out, including the flooring.
CMS Danskin Acoustics recommended a specialist
flooring for the strength and conditioning facility, consisting
of REGUPOL everroll multitile 43mm, laid over a 10mm
everroll Impact Pad protection layer.
Everroll multitile 43mm is an extra robust tile designed for
use in free weights areas, with a Force Reduction rating of
approximately 44.2%. It not only helps to minimise impact
sound, but its shock absorbing and anti-slip properties are
also designed to protect gym members during workouts.
The everoll multitile does not need to be adhered to the
subfloor - instead the 1,000 x 500mm tiles can be pegged
together for easy disassembly and reassembly at a later
date.

WHAT REGULATION CHANGES
MEAN FOR HOT WATER
While building regulations are changing all the time, some of the most significant
came into effect in June 2022. These groundbreaking reforms are a stepping stone
to the 2025 Future Homes Standard. Suzannah Adey, Product Marketing Manager
at Mira Showers, reveals the importance of planning for future regulations and
what they mean for hot water specification.
With the average new
home expected to
have 75-80% fewer
carbon emissions than
those built to current
standards, as a result of the Future
Homes Standard (FHS), specifiers,
property designers and shower
manufacturers need to consider the
impact of the new regulations now to
ensure that properties built to the new
standards can be built at scale.
In fact, these regulations and the need
to truly focus on sustainability means
that it’s becoming increasingly essential
that shower manufacturers work
collaboratively with housing developers
and contractors to incorporate
innovations in sustainability and
buildability.
How the changes might affect you
While many of the regulation changes
took place in June 2022 and came
into effect in June 2023, the bulk of
the regulation changes are part of a
roadmap towards the FHS, which
is planned for 2025. While these
regulations are set to be introduced
next year, the plans are currently out for
consultation, which was extended until
27 March 2024.
Following this, compliance with FHS will
be mandatory. The Government believes
these changes will mark an important
step towards a cleaner, greener built
environment and will help to reduce
the UK’s carbon emissions to net zero
by 2050. With that in mind, specifiers
and architects will need to be looking at
how they can meet these targets now.
Therefore, adapting to more sustainable
technologies and meeting the rigorous
A significant percentage of energy used to heat
showering water goes down the drain as shower
waste. Plus, as homes become more insulated,
the relative proportion of wasted energy linked
to showering could even increase.
requirements will be crucial for creating
resilient and energy-efficient homes.
With sustainability now a huge focus
for the whole supply chain, newly
built properties will require extensive
decarbonisation, with a range of
measures that include the improvement
of heating and hot water systems and
the reduction of heat waste.
The role of showers in energy
performance
With hot water production the second
largest user of energy in an average
UK home and showering representing
up to 50% of household hot water use,
showering can significantly impact a
property’s energy usage.
So, optimising efficient showering
systems in terms of water and energy
efficiency is becoming increasingly
important. Furthermore, there is a need
to enhance and maintain showering
experiences for the end user. Products
that reduce end user satisfaction,
30
www.specifyandbuild.co.uk \\ April 2024
such as increased noise levels or poor
performance, should not be considered
as they could lead to customer
complaints.
With sustainability an increasingly
effective indicator of building quality, it’s
imperative that shower manufacturers
use innovative ideas and engineering
to provide a positive impact. Indeed,
incorporating new technologies, such
as waste water heat recovery systems
(WWHRS), is becoming increasingly
important.
This is especially pertinent given that
studies have revealed around 85% of
the heat energy in shower water ends
up going down the drain. Essentially,
this means that a significant percentage
of energy used to heat showering water
goes down the drain as shower waste.
Plus, as homes become more insulated,
the relative proportion of wasted energy
linked to showering could even increase.
Installing a WWHRS will significantly
help to reduce the amount of energy
required per shower and the CO 2
often
associated with the production of hot
water. Doing so could recover up to 55%
of the energy that is normally lost, which
can then be used to preheat the coldwater
feed supplying the cold side of the
shower and/or the domestic hot water
heater, reducing energy costs.
How SAP assesses showers
With showering and hot water delivery
playing a huge role in a property’s energy
use and waste water heat recovery
becoming increasingly important,
showering plays a vital role in Standard
Assessment Procedures (SAP) for
the energy rating of dwellings. These
procedures assess how much energy
a dwelling will use while delivering a
defined level of service provision and
comfort and are based on standardised
assumptions for occupancy and
behaviour.
SAP will quantify a dwelling’s
performance in terms of energy use per
unit floor area, assessing the energy
efficiency rating and emissions of CO 2
.
These indicators are based on estimates
of annual energy consumption for the
provision of space heating, lighting,
ventilation and domestic hot water.
Helping achieve sustainability
targets
Design for the Environment is a vital
aspect of Mira Showers’ product
development and accordingly, Mira
Showers’ products are designed to meet
legislative targets whilst maintaining
the user experience. The Mira Minimal
was designed to offer an alternative to
traditional bar valves with its smaller
footprint, as well as in-use benefits
such as a quality showering experience
at 6 litres per minute. When used with
WWHRS, mixer showers will help

Furthermore, government-set targets
can be achieved using WWHRS. Having

requirements having never been
higher, shower manufacturers and the
construction industry have a key part to
play in working together and planning for
the future.

ROOFING AND
CLADDING
A SPECIFIERS’ GUIDE TO SCHEDULE
3 AND BLUE GREEN ROOFS
The Flood and Water Management Act Schedule 3 is expected to be implemented
this year, which means sustainable drainage systems (SuDS) will become
mandatory in England for a significant number of new and retrofit developments.
Neill Robinson-Welsh, Consultant at ACO Building Drainage discusses what specifiers
need to be aware of, especially when it comes to inner-city schemes and projects
involving blue green roofs.
With the implementation
of Schedule 3 just
over the horizon, it is
important for specifiers
working on property
development projects to have a clear
understanding of the new requirements
and how their responsibilities will likely be
impacted. By understanding Schedule
3, specifiers will be better positioned to
select the roofing solutions that fall in line
with regulations and help mitigate their
project’s impact on the environment.
What is Schedule 3?
Schedule 3 is an umbrella term
encompassing several requirements
related to sustainable drainage. It
comes from the Flood and Water
Management Act 2010 and will
mandate that all construction projects
incorporate Sustainable Drainage
Systems (SuDS). While there is still some
uncertainty around the details, once it is
implemented, Schedule 3 is expected
to impact both new developments and
renovation work on multiple dwelling
units or properties over 100 square
metres.
One major change with Schedule 3
will be that there will no longer be
an automatic right to connect new
and refurbished properties to public
sewers. Instead, permission must
be given and, in order to secure that
permission, appropriate SuDS must be
put in place and signed off by the local
SuDS Approval Body (SAB). Each local
What differentiates blue from blue green roofs is
that the latter is a home to live plants as well as
flow slowing solutions. These plants can
contribute to biodiversity and act as a natural
carbon sink, improving the air quality
authority will have its own SAB, and it is
this body that will ensure any drainage
proposal meets the standards created
by the Department for Environment,
Food and Rural Affairs (Defra).
To meet Schedule 3 requirements, it is
expected that demand for innovative
drainage systems such as blue and
blue green roofs will increase. These
are viable solutions for many drainage
projects in dense urban areas and have
a proven record of their efficacy and
sustainability.
The difference between blue and
blue green roofs
Traditionally, roofs have been designed
with the goal of removing water from a
property as quickly as possible. Blue and
blue green roofs work very differently –
intentionally slowing the flow of water
off the roof using water storage, flow
restrictors, and other features to avoid
overwhelming sewers and create more
sustainable drainage.
What differentiates blue from blue
green roofs is that the latter is a home
to live plants as well as flow slowing
solutions. These plants can contribute to
biodiversity and act as a natural carbon
38
www.specifyandbuild.co.uk \\ April 2024
sink, improving the air quality of their
immediate surroundings and offsetting
carbon emissions.
Many blue green roofs reuse some of
the collected water to sustain the plants
that fulfil the green aspects of the hybrid
design, making them especially ecofriendly
roofing options.
Relevant regulations
It’s important that specifiers keep in mind
that drainage should be selected with
those once-in-a-century rainfall events
in mind, and not just accounting for
average conditions.
Along with this consideration, blue
roofs need to be installed in compliance
with BS EN 12056-3:2000, the British
Standard for gravity drainage on flat
roofs, as well as BS 6229:2018, for
flat roofs with continuously supported
flexible waterproof coverings.
BS EN 12056-3:2000 contains design
guidance for roof and paved area
drainage, while BS 6229:2018 outlines
best practice for the design, construction
and maintenance of roofs with a flat or
curved surface.
On a technical level, it is worth noting
that blue and blue green roofs made
from solutions such as ACO’s RoofBloxx
shallow geocellular crates are attenuation
systems on roofs and not roofing
systems as such. Once installed, they sit
on top of a roof, but function separately.
It is this distinction that allows roofers to
follow both BS EN 12056-3:2000 and
BS 6229:2018, which are two seemingly
incompatible requirements. In practice,
it means water should not be allowed to
sit on top of the waterproofing layers as
that can risk causing structural damage
to the roof.
Industry changes can present
challenges, so it is important to for
specifiers to be up to date and able to

CUPACLAD ADDS DURABLE
CLADDING TO COUNTRY CLUB
CUPA PIZARRAS has installed a range of CUPACLAD rainscreen cladding on the
Cambridge Country Club building, in Cambridgeshire.
Situated in the countryside location of Bourn, Cambridge,
the Cambridge Country Club boasts an extensive
18-hole private golf course, luxury spa and function
space. Recently the club needed to replace a stretch of timber
cladding that was no longer looking its best with a more
durable cladding solution that would maintain its finish.
CUPA PIZARRAS’ CUPACLAD rainscreen cladding was
suggested by the site’s contractor Roof Brothers. Once
completed, the installation on the country club’s building not
only provides an eye-catching feature wall as part of its overall
façade, meeting the aesthetic requirements of the client, but
it also provides an ideal East Anglian location where specifiers
can see the standard CUPACLAD designs in a stunning
environment.
CUPACLAD is a ventilated natural slate rainscreen cladding
system suitable for use on both contemporary newbuilds
and traditional renovations. BBA certified, the solution has an
incredibly low level of water absorption and is very resistant
to high winds, impacts and fire, as it is classified A1 noncombustible.
It is also easy to install, maintenance free, and will
retain its colour and sheen throughout its 100-year lifespan.
joints. A system with visible fixings – CUPACLAD 201 – is also
available.
Victor Wakefiled, Company Director at Roof Brothers, says:
“We would definitely recommend the use of CUPACLAD to
clients looking for a straightforward but highly effective cladding
system. The installation is easy and in terms of design, I believe
the 101 RANDOM is the most effective and eye-catching.”
Trevor Mansfield, local Technical Sales Manager at CUPA
PIZARRAS, adds: “This is a brilliant collaboration that now
allows architects in this part of the UK to see CUPACLAD in all
its splendour and in a truly beautiful location.”
Specifiers can arrange to view the installation by getting in
touch with their local area sales manager.

The CUPACLAD 101 system – showcased at the country
club – uses invisible fixings to ensure that the slate is the main
design feature. Easily installed using stainless steel nails, the
101 range includes 101 LOGIC, which reflects the traditional
overlapping roof slate arrangement; 101 RANDOM, that
combines different sizes of slate to generate a creative and
dynamic composition; and 101 PARALLEL, which can be used
to create a homogeneous finish through its use of aligned

PITCH-PERFECT AESTHETICS
Roof pitches contribute to a building’s aesthetic appeal and also play a crucial role
in its functionality and durability. Ardit Strica, Technical Manager at Onduline
Building Products, provides a comprehensive overview of low-pitched roofs and the
challenges in specifying them.
The definition of a pitched roof,
according to British Standard
BS 5534, is a roof with a
pitch greater than 10° and
less than 75°. Anything under
20° is generally considered as a lowpitched
roof, while anything below 10° is
deemed a flat roof.
Several factors influence the selection of
a roof pitch, including material
availability, cost, aesthetics, construction
difficulty, weather conditions, and
local building permissions. The client’s
preferences and the architect’s designs
also play a pivotal role in determining
the roof pitch, as it significantly
impacts the external appearance of a
building, making it a crucial aesthetic
consideration.
The pitch of a roof is not just an
aesthetic choice but also a practical
one. Different loads, such as snow,
wind, dead load, and live load, exert
forces on a roof structure, making it
essential to tailor the pitch to suit the
local weather conditions. The choice of
roofing material further influences the
final pitch, with concrete, clay, and slate
being common options. However, low-
42
www.specifyandbuild.co.uk \\ April 2024
pitched roofs present unique challenges,
particularly in terms of effective water
drainage.
The challenge of low-pitched roofs
Low-pitched roofs, often applied to
extensions, come with their own unique
set of advantages and challenges.
While they may be considered more
aesthetically pleasing than flat roofs,
slow water runoff and limited tiling
options are key drawbacks.
In contrast to steep pitched roofs, where
water runoff is rapid due to gravity, lowpitched
roofs can struggle to shed water
efficiently. This may lead to water pooling
on the roof, causing leaks and potential
damage to the property. Additionally,
the limited availability of suitable tiles for
low-pitched roofs poses a challenge for
designers and builders.
In recent years, changes in permitted
development rights have provided
homeowners with greater flexibility
in renovating and extending their
properties, making low-pitched roofs
more appealing. The option to lower a
roof pitch gains traction as it allows for
additional ceiling space, aligning with the
increased trend in property extensions
and renovations.
The choice of roof pitch becomes crucial
in home extensions, with flat roofs being
a common option due to their spacesaving
and contemporary aesthetics.
However, pitched roofs, especially
those matching the main property,
contribute to a more cohesive visual
appeal. The introduction of low-pitched
roofs in extensions, in particular, provide
an opportunity to use matching tiles,
ensuring uniformity with the existing
property.
The role of sub-roof systems
While low-pitched roofs offer several
advantages, the limitation in available
roofing tiles has been a significant
hurdle. This is where sub-roof systems
come into play, helping to increase the
possibilities for specifiers when it comes
to roofing design and functionality.
A sub-roof is an additional protective
layer within the roof structure, acting as
the primary waterproofing layer under
the tiles when the tiles’ minimum pitch
cannot be met. British Standard BS
5534 acknowledges situations where
using roofing products below the
recommended pitch is challenging and
emphasises the need for a functional
weatherproof sub-roof system.
Sub-roof systems change the dynamics
of traditional roof structures. Instead of
relying solely on tiles for waterproofing,
the sub-roof becomes the main
waterproofing layer, allowing the tiles to
serve as a secondary defence against
water ingress. This enables the use of
all types of concrete, slate, and clay roof
tiles, even at pitches as low as 10°.
Flat sub-roofs, involving non-breathable
felt on a rigid sarking board, and
corrugated sub-roofs, using bituminous
corrugated roof sheets, are two
prevalent options in the market. While
One significant advantage of sub-roof systems is
their ability to accommodate heritage sites and
older properties.
both provide solutions for low-pitched
roofs, corrugated sub-roofs offer
enhanced ventilation, minimising the risk
of moisture build-up and timber rot.
The rise in popularity of sub-roof systems
is attributed to the newfound freedom
they offer in roofing projects. Whether
the project involves a low-pitched roof or
not, a suitable sub-roof system provides
flexibility in choosing roof tiles, enhancing
both aesthetics and functionality.
One significant advantage of sub-roof
systems is their ability to accommodate
heritage sites and older properties. By
allowing the use of existing or reclaimed
tiles, sub-roofs maintain the original look
and feel of the property while providing
an additional layer of protection against
water ingress.
A prime example of an innovative subroof
system is Onduline’s ISOLINE LOW
LINE solution, which is BRE tested
and BBA accredited to as low as 10 o
with a 30-year guarantee. Made from
approximately 50% recycled material
and specifically designed for use on low
pitch roofs, this lightweight bituminous
underlay sheeting is fitted under roof
tiles, thus being shielded from elements
such as wind and rain, making it an
exceptional long-lasting waterproofing
solution.
ROOFING AND
CLADDING
As the construction industry continues
to evolve, innovations such as sub-roof
systems play a crucial role in addressing
challenges and expanding possibilities.
The ability to create visually appealing,
functional, and watertight low-pitched
roofs opens up new avenues for
architectural creativity and sustainable
construction practices. With a deeper
understanding of these concepts,
professionals in the field can make
informed decisions that contribute to
the overall success and longevity of their
projects.

WRAPTITE OFFERS PROTECTION
FOR INNOVATIVE ECO HOUSE
A new ecological house in the Outer Hebrides is being protected against the elements by A
Proctor Group’s Wraptite external barrier system. Specify & Build reports.
The Wraptite external air barrier system from A.
Proctor Group has provided the significant benefits of
airtightness and enhanced build quality for a sea lochfacing
property on the isle of North Uist in the Outer Hebrides.
7-22 Systems, an ecological construction business based
in the Southern Isles of the Outer Hebrides, has built a small
house and artist’s studio using its ecological, prefabricated
offsite building system. 7-22 Systems was formed by
experienced Uist-based Fraser Architecture in response to the
practical and design challenges of delivering the best value,
high quality, environmentally sustainable buildings.
The key requirements for the project at 27 Locheport, North
Uist, included the speed of assembly, excellent insulation
values, lots of natural light and the efficient use of space. Alex
Durie, architect and co-founder of 7-22 Systems explains:
“Using Wraptite, 7-22 Systems could pre-apply the breather
membrane to each prefabricated component in their dedicated
controlled workshop setting. The A. Proctor Group pre-cut
the rolls to match the sizes of the external faces of each
component, and then Wraptite tape was applied on-site to lap
between the components.
“Wraptite has enabled 7-22 Systems to build to even greater
quality, add another facet to their prefabrication, and provide
the system with the breathable construction that will benefit the
quality of space offered by their buildings.”
The Wraptite air barrier system is a safe and simplified
membrane system. It provides a fully self-adhered vapour
permeable air barrier certified by the BBA and combines the
critical properties of vapour permeability and airtightness.
Wraptite has a robust two component solution comprising
Wraptite and Wraptite Tape. This approach saves on both
the labour and material costs associated with meeting the
demands of modern energy efficiency requirements in both
commercial and residential buildings.
Exposure to the elements can present challenges when
designing for a remote location or during transportation to the
site of offsite components. However, the self-adhesive Wraptite
membrane is easily applied in the factory, bonded externally
to the substrate, and ensures that the membrane is held firmly
in place, even during transportation, maintaining the system’s
quality from installation to finished build.
Alex Durie adds: “Wraptite has enabled 7-22 Systems to
meet their targets for the on-site assembly of the project. It
is a high-quality material that holds up well to severe weather
conditions. The Wraptite membrane works well in a factory
setting and is robust enough to withstand delivery to the site.
Previously, applying on-site with the requirement of dry timber
to apply a membrane to has been a challenge in the unsettled
Hebridean weather.
“The ease of handling in a prefabrication setting is a great
benefit. In addition, providing clients with a breathable
construction is an added benefit and improves the durability of
our system. Wraptite has definitely increased our prefabrication
productivity compared to traditional rolls of breather
membrane.”

SEEKING DURABLE BUILDING
ENVELOPE SOLUTIONS
As the industry focuses on the delivery of sustainable buildings, the durability of materials
specified will have a key role to play. Dr. Peter Barker, Manager New Product Development
at Tata Steel, explores how considering the long-term performance of the building
envelope is key to delivering a whole-life carbon benefit.
The built environment
generates around 40% of our
global carbon emissions – a
well-known figure that the
industry is working hard to
reduce. While there are many factors at
play here, product durability is a vital part
of achieving more sustainable building
envelopes that deliver in-use benefits.
While a building is generally expected to
have a lifespan in excess of 40 years, the
reality can be very different, with location,
usage and materials used all contributing
to the ultimate design life.
Imagine specifying and installing a
steel cladding system that only lasts
10 years before it deteriorates and
requires remedial works. The resources
and embodied carbon spent on
repairing, or removing and replacing
the building envelope system would be
significant. Instead, by making informed
specification decisions and choosing
long-lasting, high-quality solutions
backed up by comprehensive test
evidence, we can do our bit in helping
to build the sustainable structures of the
future.
Steel buildings have evolved significantly,
from simply meeting a need to keep
contents (whether produce or people)
dry, to now enabling specifiers to create
high-quality, aesthetic and incredibly
long-lasting building envelopes.
Building requirements have also now
changed, making it important to look
at the value ‘in-use’ over the life of the
building. Building owners want their
building to stay looking good for a longer
period of time. With this in mind, it’s
easy to see why pre-finished steel has
fast become one of the most popular
building envelope solutions worldwide,
thanks to the design advantages,
maintenance benefits and corrosion
resistance it can offer throughout a
building’s lifecycle.
That said, it’s important to note that not
all pre-finished steel products offer the
same performance levels. A key feature
of pre-finished steel is the numerous
layers that make up its composition, with
paint layers, primers and pre-treatments
all applied to the steel in an automated
and carefully controlled process.
It is the quality, type, thickness,
consistency and application of these
layers that dictate the overall durability
and quality of the steel, resulting in a
material that is truly robust, versatile and
aesthetically pleasing.

CLADDING
40%

emissions are generated
by the built
environment
A great example of this is the prefinished
steel’s topcoat, ranging from a
nominal thickness of 25 microns to 200
microns. To put this into perspective,
the paint thickness on modern cars
is around 120 microns, with buildings
expected to last a lot longer. This is
especially important to consider from a
building lifespan perspective, as well as
a functional point of view. For example,
if you are looking to install renewable
energy systems on the building, such as
solar photovoltaic modules, you must
consider the robustness of the topcoat
during installation.
Another essential layer is the metallic
coating on pre-finished steel products,
traditionally 100% zinc and often referred
to as a Hot-Dipped Galvanised Steel
(HDG). While this HDG coating does
provide improved corrosion protection,
when compared to uncoated steel it
can still leave cut edges vulnerable to
increased rates of corrosion, as well
as any corrosive attack dissolving all
the metallic coating at the same rate.
In comparison, pre-finished steel with
an alloy metallic coating (such as zinc
and aluminium) can offer a combination
of increased barrier and sacrificial
protection, with the metals corroding at
different rates.
By taking a closer look at the layers of
a pre-finished steel product, you can
have a better idea of how well it will
stand up to corrosion and UV radiation
during the building’s lifespan. The latter is
particularly destructive to paint coatings,
with the UV rays directly absorbed
and known to affect the colour’s gloss
resistance. Fortunately, European
Standards have put ratings into place
to help specifiers understand how
pre-finished steel solutions will perform,
so they can make more informed
specification decisions from a corrosion
and UV performance point of view.
For example, EN 10169 classifies the
corrosion resistance of pre-finished
steel using the ratings RC1 to RC5+.
To achieve RC5+, the pre-finished steel
must be subjected to extensive natural
weathering tests, spending a minimum
of four years at an extreme coastal
location (certified as a C5 environment)
and resisting blistering, surface damage
and edge peel to less than 2mm.
Product durability is a
vital part of achieving
more sustainable
building envelopes that
deliver in-use benefits.
Despite Ruv and RC ratings highlighting
the performance of different factors,
they should not be considered in
isolation. Instead, specifiers should look
at choosing products that meet all the
requirements of the project, as well as
being backed up with a comprehensive
guarantee.
In an era when embodied carbon
is driving specification choices, it’s
important to consider ‘in use’ carbon
to get a real view of the building’s
carbon lifecycle. Otherwise, any savings
achieved at the upfront carbon stage
may be negligible in the life of the
building. A key part of this is to consider
the durability of building systems
specified and real-life examples of
performance, to further maximise the
project’s lifespan and reduce its carbon
footprint.
www.colorcoat-online.com
Tata Steel’s Colorcoat HPS200 Ultra pre-finished steel combines outstanding performance with
exceptional durability, designed to withstand even the most demanding and aggressive environments.
Its multi-layered, 200-micron thick structure incorporates a unique protective layer and the latest
polymer technology, as well as the Galvalloy metallic coating, made with a special mix of 95% Zinc and 5%
Aluminium. Having been installed around the world in many demanding environments, including the Middle
East, South America and the Far East, Colorcoat HPS200 Ultra surpasses the requirements of Ruv4 and RC5+
as per EN 10169:2022, proving excellent colour and gloss retention and corrosion resistance.
Furthermore, the product is chrome free (a requirement for all products manufactured in Europe since 2017),
REACH compliant and comes with the industry renowned Confidex guarantee. This offers up to 40 years
protection for industrial and commercial buildings – the most comprehensive guarantee on the market – and is
direct to the building owner, with full rectification in the event of a failure.

PREVENTING PEELING PAINT
PROBLEMS
Cladding Coatings offers specifiers advice on the causes, consequences and
solutions to peeling paint problems in buildings.
When you carry out external
maintenance checks on a
property, one of the most
important things to look out for is peeling
paint. It’s a really common issue faced by
many building owners and is often found
on metal cladding and roofing sheets.
The appearance of peeling paint on
metal wall cladding is not only unsightly,
but it can also lead to costly problems. It
can cause damage to the metal surface,
impact the overall appearance of the
building, and impact the durability of
the protective coating. Therefore, it’s
essential to address peeling paint issues
as soon as possible.
Of course, peeling paint doesn’t occur
without warning, which is why it is
important to carry out regular checks on
the condition of the paintwork so that it
can be spotted early and repaired before
more serious consequences arise.
Before peeling occurs, paint on both roof
and wall metal cladding sheets or panels
will normally begin to fade, and it will

happening in the first
place.
then start to chalk, meaning fine white
lines start to appear. After this stage the
paint begins to peel away from the metal
surface and flake away.
What causes paint to peel?
Peeling paint on metal wall cladding
is often a result of poor adhesion
between the metal surface and the
paint layer. This can be attributed
to a range of factors such as poor
surface preparation, insufficient coating
thickness, inferior quality paint products,
and exposure to extreme environmental
conditions like heat, moisture, or UV
radiation. Additionally, peeling paint can
occur due to the use of incompatible
coatings that are poorly designed for use
on metal substrates.
What problems does it cause?
Peeling paint can lead to multiple
problems, including aesthetic issues,
corrosion and reduced durability of the
protective coating. When paint chips or
peels off, it exposes the underlying metal
surface to the external environment,
making it more vulnerable to rust and
other forms of corrosion. Moreover, the
unsightly appearance of peeling paint
can impact the value of the building and
make it appear unattractive to potential
buyers or tenants.
How to fix peeling paint
The best way to fix peeling paint is to
prevent it from happening in the first
place by using high-quality coating
systems that are designed for use with
metal substrates. However, if peeling
paint has already occurred, it requires
specialised treatment to repair.
The Cladding Coatings team can
prepare a building’s surface by removing
any loose paint from the metal cladding.
Once prepared, the wall or roof is then
re-coated with high-performance coating
systems that are guaranteed for a
minimum of 10 years. Any areas of cut
edge corrosion that may have occurred
due to the paint peeling away and
exposing the metal surface can also be
repaired at the same time.
High-quality paint systems
The Cladding Coatings team uses
paint systems that are tried and tested
and guaranteed to last. Using these
leading coatings systems, combined
with our team’s expertise, results in a
professionally applied, high-quality finish
that will last for over a decade.
Peeling paint is a common issue that
building owners face, and it can lead
to serious problems if not addressed
promptly. It’s important to understand
the causes, consequences, and
solutions of peeling paint to protect
your metal wall cladding and keep your
building looking great. By choosing a
reputable coating solutions provider,
such as Cladding Coatings, specifiers
can have peace of mind that the building
is protected with high-performance
coating systems that prevent peeling of
paint and keep your metal wall cladding
looking as good as new.

EFFECTIVE COMMUNICATION
ELEVATES CONSTRUCTION
SPECIFICATIONS
Dan Hancox, Corporate Sustainability and Development Director at Russell Roof Tiles,
explains how better communication between stakeholders can result in more
support for specifiers and, ultimately, higher quality buildings.
Effective communication
among key stakeholders
is vital in the construction
industry, where projects often
hinge on intricate coordination
and collaboration. According to the
Project Management Institute, poor
communication contributes to the failure
of one-third of construction projects, with
only 52% meeting their original targets.
As the industry grapples with challenges
ranging from escalating costs and
material shortages to labour deficits,
the need for cohesive communication
between material manufacturers and
specifiers has never been more pressing.
In the face of these challenges,
businesses operating within the
construction supply chain must
recognise the substantial costs that
could be incurred due to a lack of unity.
With billions lost annually, overlooking
communication gaps is a luxury that the
industry can no longer afford.
Collaborating effectively and establishing
clear lines of communication with
material manufacturers’ technical
support teams is essential. These teams
play a pivotal role in driving specifications
forward and guiding projects across their
lifecycle, as well as helping specifiers
identify and choose the right products.
However, with budgets being stretched
further than ever before, there is the
danger that specifiers may prioritise
cheaper products over quality ones,
especially when it comes to roof tiles.
Despite these constraints, it remains
essential that buildings are constructed
to the highest specification, using the
right roofing product and accessories.
It is also important that the projects
remain in line with legislation changes,
which have been increasingly tightening
requirements recently, emphasising the
need for meticulous attention to detail
when specifying products.
Delivering quality and reliability
Manufacturers throughout the
construction industry consistently
underline the rigorous standards
products must meet to deliver on
quality and reliability. Yet it is crucial
to adopt a holistic perspective when
evaluating roofing systems, to ensure
optimum performance and longevity.
Manufacturers such as Russell Roof
Tiles specify concrete roof tiles and
50
www.specifyandbuild.co.uk \\ April 2024
accompanying accessories, where every
component plays a vital role in the overall
system.
For example, Russell Roof Tiles provides
RussSpec – which has a 15-year
guarantee when using the whole roof
solution. This is applicable where the
specification has been followed and
detailed in accordance with advice
provided in the fixing specification and
instruction. Having guarantees of this
kind in place means the specifier can
rest assured that the manufacturer is
committed to providing a high-quality
product. These roofing systems are
meticulously developed for specific
products, and so, the inclusion of
third-party fittings or components
may compromise the validity of these
assurances.
Deviating from specified accessories
could introduce compatibility issues,
potentially affecting the whole roofing
system’s performance and appearance.
Additionally, customer support and
technical service are intricately linked to
the use of recommended accessories,
making it challenging to extend the same
level of support for accessories from
other manufacturers.
By working closely with specifiers,
manufacturers’ technical teams
provide invaluable insights into a
product’s features and limitations. This
collaborative approach ensures that
specifications align with regulatory
standards and project requirements,
mitigating risks and enhancing project
outcomes.
It is also important to be aware of the
guarantee’s limitations. For example,
products must be installed as specified
and any substitution of components
with other products, at any stage of
construction, will invalidate guarantees.
By working closely with a manufacturer
that offers guarantees, the contractor is
in a stronger position to ensure a viable
roofing solution that meets all their future
needs.
Specifiers who communicate and work
closely with a manufacturing technical
team will have more confidence in their
products and will find it easier to check
compliance, which will inevitably prevent
build developments from going over their
allotted timescales and any associated
consequential losses, which will save
money and time in the long run.
Russell Roof Tiles exemplifies the
importance of a robust technical
support team. Over the past decade,
the company has bolstered its support
team to cater to the increasing demand
for expert guidance. The team receives
many calls per week with all manner of
queries and has recently seen an influx
of enquiries following the rising costs and
uncertainty of the supply chain.

By collaborating with insightful,
experienced, and knowledgeable
technical experts, manufacturers can
help to build smooth procedures for
seamless transitions from the planning
and design right through to installation
and client handover. It eliminates
problems or compatibility issues before
they arise and reduces liabilities down
the chain.
This relationship between specifiers and
a manufacturer’s technical team needs
to be seen as a necessity rather than
a luxury, as it will help to reduce issues
before, during, and after installation as
well as giving contractors peace of mind
that projects are built using consistent
and quality products with long service life
and durability.

INSULATION AND
ACOUSTICS
SOUND ADVICE FOR CREATING
IDEAL LEARNING AND WORK
SPACES
Mat Hartley, Partitions Business Development Manager at QIC Interiors Specialist,
explains why specifiers need to understand acoustics to create positive public and
commercial spaces.
Sound waves respond differently
depending on the surface
they impact with. International
standard EN ISO 11654 part-highlights
this process by compartmentalising
sound absorption into different classes
(A-to-E). Class ‘A’ is designated as the
most sound-absorptive, but it isn’t the
sole answer to striking the right acoustic
balance in places where effective
communication isn’t compromised by
extraneous noise, and particularly in
public and commercial environments.
Sound absorption occurs when sound
waves dissipate upon meeting an
absorptive material. Set out in EN ISO
11654, the absorption value is recorded
as a weighted single figure (αw), with
0.0 being no sound absorbency and 1.0
being 100%. If a product has αw 0.9 it
absorbs 90% of the sound and belongs
to Class A. Class A would often appear
the ideal solution for a project where
acoustics were a key consideration,
however, this is not always the case.
With each project’s unique acoustic
requirements, it is important to consider
what class sound absorption is best to
achieve the desired outcomes.
Understanding the applications of
different sound absorption classes is
important. There are environments
where the highest sound absorption
class would be the most beneficial,
for example large, high-volume places
where silence is important, such as
school classrooms, sports halls, concert
venues, cinemas, theatres and recording
studios.
However, extremely high sound
absorption isn’t always the most
effective answer. It can deaden acoustics
in places relying on a certain amount
of atmosphere-enhancing noise. For
example, in a restaurant you want to be
able to communicate comfortably with
your fellow diners, but some background
noise is needed to instil a sense of
occasion.
The acoustic benefits of
demountable glass partitions
Creating spaces that suit the individual
and group dynamic is equally pertinent
to schools. Particularly when School
Census figures in England for 2021/22
revealed that nearly 1,800 Reception
and Key Stage 1 classes exceeded the
statutory limit of 30 pupils per class. The
same report, published via NASUWT, the
Teachers’ Union website, revealed that at
Key Stage 2 level, more than 16% of Key
Stage 2 pupils were taught in classes of
31 pupils or more.
The higher the classroom number,
the greater opportunity for noise and
distraction to detract from the learning
experience. A University of Portsmouth
study found that pupils most at risk of
school difficulty were also more likely to
be annoyed and distracted by classroom
noise. In such an environment,
demountable glass partitions are adept
at creating spaces that are productive
and collegiate.
Easy to install and disassemble,
demountable partitions can transform
learning spaces and other areas
where occupant comfort and clear
communication are crucial. They also
negate the need for costly refurbishment,
a valued benefit for state-run schools
and colleges where budgets are often
tight.
There is also a growing awareness in
the commercial world of the value of
demountable partitions. Taking a onesize-fits-all
approach to office design,
for example, doesn’t always achieve the
desired effect. That’s why demountable
partitions are a gift for employers, as
they can be used to create areas that
acoustically, cater for individual needs.
Open plan offices can be very noisy,
stressful places, leading to individuals
feeling overwhelmed. Demountable
partitions help cocoon staff from the
hustle and bustle, providing an oasis
of solitude when working in peace
and quiet is preferred. A well-designed
demountable partition system can
offer up to 50% noise reduction,
allowing students or employees to
better-focus on activities at hand.
Therefore, demountable partitions could
be a genuine game-changer for high
intake schools and busy offices where
traditional interior design is hindering
communication, concentration and
occupant wellbeing.

INSULATION AND
ACOUSTICS
SPECIFY PIR AS A PATHWAY TO
ENERGY COMPLIANT HOMES
Simon Blackham, Senior Technical Manager at Recticel Insulation, looks at the issues to
consider when selecting a PIR system that paves the way for regulation-compliant homes.
The latest Part L regulations,
introduced in June 2022, provide
an interim lift to required energy
standards for newbuild homes, before
a further strengthening of legislation
is brought in with the Future Homes
Standard (FHS) in 2025. Part L’s primary
objective is to achieve a 31% reduction
in carbon emissions from newbuild
homes, accomplished through a
combination of fabric enhancements and
low-carbon heating technologies.
The amendments also entail stricter
standards for older homes in relation to
extensions, replacements and upgrades.
Current legislation puts a focus on
improving the energy efficiency of new
homes through a fabric-first approach
to design. Key to this process – and
creating an effective thermal envelope
– is the specification of appropriate
polyisocyanurate (PIR) insulation.
Targeting CO 2
through legislation
The new Part L regulations are
considered a critical stepping stone
towards the FHS, which aims to
achieve a 75 to 80% reduction in
carbon emissions compared to current
standards. The FHS is a transformative
shift in the construction industry’s
approach to building homes and will
introduce several initiatives to ensure
homes meet the required energy
performance. Such initiatives bring
a more stringent onsite monitoring
process, with contractors being required
to document critical junctions via
geo-located digital photographs. This
transparency enables homeowners to
better understand the as-built energy
calculation of their property.
The FHS will emphasise a more holistic
approach in assessing a property’s
anticipated energy performance, using
an updated Standard Assessment
Procedure (SAP) methodology. It will
place greater emphasis on heat losses
at junction details such as windows,
which are calculated using the PSI value
method. Although seemingly minor,
these amendments could be crucial
to ensuring the necessary thermal
outcomes are achieved.
The FHS underscores the need to
improve the energy standards of a
building’s fabric, with a particular focus
on insulation. Inadequate insulation
is a significant contributor to energy
wastage in domestic buildings and
leads to buildings falling short of U-value
requirements. PIR panels are regarded
as a long-term solution that can
address this energy performance gap,
when compared to mineral fibre-based
insulation.
The value of PIR in meeting targets
In performance and installation terms,
PIR insulation is ideal for fabric-first
design. Lightweight and easy to handle,
PIR is a versatile product that delivers
consistent thermal performance and
product reliability for walls, floors,
pitched roofs and flat roofs over time.
With impressive lambda values as low as
0.022W/mK, PIR insulation offers users
excellent performance and quality in
relation to cost.
PIR’s thermal performance isn’t
compromised by its slim composition,
and it requires less thickness to achieve
the same U-value as other insulation
materials. This benefit is particularly
valuable for housebuilders seeking to
maximise interior living space and plots
per area in multi-property developments.
It is also a means to achieving U-value
targets in applications such as terraces
and balconies, where space is limited
and threshold levels are an issue.
Enhanced PIR performance
Recticel Insulation specialises in PIR
products which are suitable for fabricfirst
construction thanks to their good
thermal performance. The tongueand-groove
joint found on Recticel’s
Eurowall+ rigid full-fill insulation board
has further enhanced PIR performance.
This design feature, combined with
a 10mm air gap created by a 90mm
Eurowall+ PIR board in a traditional
100mm masonry cavity wall, facilitates
a more convenient installation process
for bricklayers. It also ensures Eurowall+
panels achieve regulation targets for
walls with a traditional 100mm cavity
size.
Amended Part L legislation and the
subsequent implementation of the FHS
will present challenges for specifiers
across the industry. However the stricter
regulations, which highlight fabric-first
design as a route to carbon-efficient
buildings, are essential if we are to
deliver energy compliant homes now and
in the future.

COLLEGE ACOUSTICS UP TO DATE
A leading Oxford University College has seen its acoustic performance significantly
upgraded thanks to the use of the StoSilent Direct acoustic ceiling system.
able to satisfy all these
requirements,” says Harry
Austin of Alpine Finishing,
which installed the acoustic
products. “Working together
with Sto and Associated
Architects was also very
beneficial, as we were able
to pool our expertise and
create a really successful
solution.”
The StoSilent Direct system has been installed at
Somerville College as part of a major project to upgrade
both the acoustics and the lighting of the Grade II-listed
dining hall.
“This was a complex project where the aim was to create a
much-improved acoustic environment in the hall,” explains
Sto’s acoustics project manager, James Gosling. “The hall is
used both for dining and for formal events, so outstanding
acoustic performance was a key requirement. The aim was
to increase the amount of acoustic attenuation material
within the moulded panels of the existing vaulted ceiling,
but the chosen acoustic system also had to be sufficiently
flexible to accommodate the new lighting system which was
being installed. The project demanded close liaison between
ourselves, the architect and the applicator to design and install
the most effective and appropriate solution possible.”
Thomas Cotton of Associated Architects continues: “We knew
that Sto had worked on similar, historically-sensitive projects
in the past, and that experience was a key requirement for
us. Refurbishing buildings of this age comes with particular
challenges, so it was important that we worked with a proven
acoustic ceiling supplier and installer who understood our
requirement for high-performance absorption with minimal
visual impact.”
The chosen system also had to offer a high degree of flexibility
in terms of design and installation. Associated Architects was
looking for a system that could be applied directly onto the
existing structure, but which would have minimal physical and
visual impact. This project involved a very significant heritage
building and the acoustic boards had to integrate as closely as
possible with the existing ceiling beams and surfaces.
“The Sto system is extremely adaptable and so it was
The StoSilent Direct
system offers a particularly
economical method of
minimising reverberation
times and reducing noise
levels, as it can be applied
directly to walls and ceilings
without the need for a sub-construction – a feature which also
makes it quick and easy to install.
The acoustically porous nature of the materials and finish
textures mean that the system is highly sound absorbent and,
in addition, has a reaction to fire classification of A2-s1, d0 in
accordance with EN 13501-1.
The Sto system was completed with a StoSilent Top Finish
to blend with the existing refurbished ceiling features. This
organic, porous finishing coat is trowel-applied, and has an
ultra-fine grain size to allow the creation of smooth surfaces
across ceiling areas. It is environmentally friendly and available
in a large range of colours, making it compatible with a wide
range of architectural and design styles.
The wood-panelled Somerville College hall features raised
stage areas at either end, and these required a slightly
different treatment. Bespoke acoustic modules constructed
from Sto’s StoSilent Distance system were created and then
installed above the raised platform areas to add extra acoustic
attenuation.
Somerville College is a constituent college of the University of
Oxford. It was founded in 1879, and former students include
prime ministers and pioneers in the fields of literature, science
and public service.
Working closely with architects, designers and specifiers, Sto
provides extensive technical guidance including samples,
specifications, consultations, design tools and on-site support.
The company also runs a series of RIBA-accredited CPD
seminars covering topics such as render, externally insulated
and rainscreen cladding systems, and acoustic reverberation
control systems.

SPECIAL FEATURE
LINOLEUM: SPECIFYING FOR
SUSTAINABILITY
With sustainability now a major focus for construction, specifying environmentally friendly
products is key. Donna Hannaway, Forbo Flooring Systems’ Head of Marketing UK and
Ireland explores the benefits of linoleum for interior spaces.
It’s a well-known fact that the built environment accounts for
over 40% of all carbon emissions globally. As a result, many
specifiers are under pressure to reduce the carbon footprint
of their projects, through the specification of environmentally
conscious products and materials.
One such example of this is linoleum. Widely regarded as
one of the most sustainable floor coverings on the market,
linoleum is made using natural, renewable raw materials, such
as linseed oil, jute, pine rosin and wood or cork flour. In fact,
it was linseed oil that ‘accidentally’ inspired the creation of
linoleum in 1863, when Frederick Walton watched the linseed
oil used in paint harden on the surface, thus creating linoleum.
These ingredients are all naturally occurring, therefore making
linoleum an ideal choice for sustainability focused projects.
Some manufacturers have taken this a step further, offering
linoleum that is independently certified as Climate Positive from
cradle to gate, without offsetting. This means that the CO 2
produced in the extraction, transportation and manufacturing
of the floor covering is more than balanced out by the removal
of CO 2
during the growth process of its natural materials.
Forbo’s Marmoleum range has been independently proven
to be Climate Positive, with a full Environmental Product
Declaration to back this. Marmoleum is Climate Positive from
cradle to gate without the need for offsetting, providing a 446g
carbon saving for every square metre that is installed on a
project.
Thanks to new technologies, linoleum has evolved to be
suitable for even the most demanding of interior environments.
Top layers and finishes, such as Forbo’s Topshield pro, allow
for easier cleaning, with minimal chemicals required, as well as
providing additional resistance to the daily scrapes and wear
expected on an interior floor covering. These finishes not only
ensure that the linoleum floor coverings look great, but that
they lead a longer service life too – all helping to improve its
sustainable credentials.
While linoleum floor coverings can be used in all applications,
one sector where it can be particularly beneficial is healthcare.
Thanks to the use of linseed oil in the production of linoleum,
it is inherently bacteriostatic, and some manufacturers have
had their linoleum products certified as being able to inhibit the
growth of C Difficile, Norovirus and MRSA – without the need
for surface additives.
Linoleum also has Total Volatile Organic Compounds (TVOCs)
that are 30 times lower than the European norm and 50%
lower CO 2
emissions than other resilient floor coverings. This
means linoleum can contribute to better indoor environments,
whether that be for healthcare or any other sector. Some
brands of linoleum also boast the prestigious Allergy UK Seal
of Approval, meaning that with the correct cleaning regime the
flooring will not harbour allergens or house dust mites.
Of course, it isn’t just the functionality of a solution that’s
important, but its design too. New developments have
expanded the range of finishes linoleum floor coverings
are available in, whether that be contemporary shades and
patterns, or wood inspired designs. A great example of this
is Forbo’s newly refreshed Marmoleum Solid, which offers a
range of aesthetic options. Take Marmoleum Cocoa, which
incorporates recycled cocoa husks into its production,
helping to create stylish and sustainable flooring schemes.
The colourways in Marmoleum Concrete, by contrast, are
inspired by stone and concrete textures, providing a natural
finish and helping to promote biophilic design and increase
wellbeing. There is also Marmoleum Walton, which contains
a range of plain options for environments where those with a
neurodiversity, such as dementia, may be living.

Building Regulations, which ban combustible materials in
external walls of buildings over 11m, the existing expanded
polystyrene insulation (EPS) system installed by another
manufacturer had to be removed and replaced.
CASE STUDIES
The project’s first phase comprised two buildings which
had the StoTherm Mineral K EWI system specified to
meet the required fire rating while maximising thermal
performance. BBA-certified, StoTherm Mineral K features
A1 mineral fibre insulation boards and the system is
classified with an A2-s1, d0 reaction to fire in accordance
with BS EN 13501.
Specialist surface finisher One & Maike was responsible
for installing StoTherm Mineral K on behalf of principal
contractor Osprey, a façade remediation specialist.
The insulation boards were fixed directly to the existing
concrete substrate avoiding the need for a cavity. StoLevell
Duo Plus, a strong mineral adhesive, was applied to the
back of the insulation boards, and additional fixings were
also used to secure the insulation boards to the substrate
to suit wind load conditions. Sto-Glass Fibre Mesh was then
embedded into the outer surface of the reinforcing coat
providing crack resistance to the system.
The system was finished with StoSilco K1.5, a silicone
resin render ensuring high levels of water repellence and
protection from harsh weather conditions. This was applied
across an area totalling 2,500m 2 , creating elevations
featuring various colours, including white, terracotta and
blue.

CLASS 1 MAGPLY BOARDS WITHSTAND REAL-LIFE FIRE TEST ON SURREY HOME
A potentially catastrophic blaze that consumed the garage
adjoining a £1m property in Surrey was stopped in its
tracks thanks to the use of 12mm A1 non-combustible
Magply being chosen as the render substrate board on the
contract.
The property was constructed using a Structurally Insulated
Panel system construction (SIP), with A1 non-combustible
Magply being used on the exterior of the building as the
substrate panel for the proprietary render system.
Magply is a multi-use A1 non-combustible board with an
impressive library of testing for fire applications. In the
offsite and timber frame sector the board is designed and
specified to contain fire and support the emergency service
with added crucial time.
Although the emergency services were quick to attend the
fire, which happened in August, it had taken sufficient hold
that the large timber framed garage was totally destroyed
with just some sections of the frame still standing. However,
the gable end to the house, which features a relatively thin,
weatherproof finish of the silica-based K-Rend suffered
only surface damage.
Although areas of the render had spalled off, the 12mm
Magply boards underneath had not even charred and had
fully protected the SIPs structure beneath: a fact borne
out by the system supplier, Glosford SIPs, which took core
samples to confirm the continued integrity of the insulated
sandwich panels which are faced by OSB.
Contracts Manager for Fullers Plastering, James Corlett,
said: “The fire-resistant qualities of the Magply boards
saved the day. We had used Magply as a render-backer
on a number of projects before being awarded the contract
to apply K-Rend to the half dozen homes here and have
always been very pleased with the performance. It is an
easy board to cut and fix, while we can now definitely
confirm to clients that it fully complies with the fire
requirements for domestic and commercial buildings.”

CASE STUDY
AIRTIGHT PROTECTION FOR WEST
COAST OF SCOTLAND SELF-BUILD
The threefold combination of
the Wraptite, Wraptherm and
Reflectatherm airtightness and
vapour barrier systems from A. Proctor
Group has been chosen to provide
enhanced thermal performance and
protection for a sea-facing SIPS
construction self-build property on the
west coast of Scotland.
The self-build project, managed by Phil
and Lynn Dickinson, is designed by
Allan Corfield Architects, and located
in Craobh Haven – a unique location
that combines the beauty of an Atlantic
Rainforest with stunning sea views.
Craobh Haven is a small, purpose-built
village and sailing port on the west coast
of Argyll and Bute, Scotland. The main
contractor for the project is Rochead
Irvine Construction.
The key requirements for the project
included a fabric-first design, SIPS
construction and breathability, plus
protection from the Argyll coast exposed
site. In addition, the client’s design
sought to achieve excellent insulation
values and highly efficient thermal airtight
performance.
detailing made it an ideal choice for this
self-build project.
The self-adhering nature of the Wraptite
allows a simple and fast installation
process. It also has excellent weather
protection and water-tightness
properties. The membrane can be
installed directly to walls and openings
with speed and efficiency, enabling
internal fit-out to begin more rapidly than
in traditional forms of construction.
Wraptite has an Sd-value of 0.039m,
offering a fast and effective solution
to unplanned air leakage and its
dertrimental effects on energy
performance. It can be used on projects
from domestic scale timber frame to
steel framed high rise and everything in
between.
Alongside the Wraptite membrane, the
thermal and airtightness performance
of Wraptherm is included in the build.
Wraptherm is a high-performance
membrane composite that is selfadhesive
and consists of a 10mm
Spacetherm aerogel insulation blanket
bonded to the face of Wraptite.
Using Wraptherm provides improved
airtightness levels combined with a
reduction in thermal bridging.
The final part of the airtightness and
vapour barrier system is provided
by Reflectatherm Plus, a reflective,
high-resistance vapour barrier for
internal walls, ceilings and floors that
will significantly reduce the risks of
condensation by providing the highest
levels of moisture resistance.
Reflectatherm Plus is an reflective vapour
barrier that combines the highest thermal
performance in its class with a high
vapour resistance to prevent interstitial
condensation and is suitable for use in
walls, ceilings, and floors on the warm
side of the insulation.
The clients were supported throughout
the project by the A. Proctor Group’s
technical team. The company offers
expert advice for self-builders available
at all stages of the building process, from
design work to on-site support.

Keep the building wrapped tight
Wraptite is installed as an external air
barrier and an alternative to a traditional
standard breather membrane. Wraptite is
the only self-adhering vapour-permeable
air barrier certified by the BBA and
combines the essential properties of
vapour permeability and airtightness in
one self-adhering membrane. The selfadhered
nature of Wraptite and its high
level of water resistance and simplified
