By the time this issue lands on your doorstep, the
Chancellor will have delivered his Spring Budget
and we’ll have a better sense of the state of the
economy as we head towards the next General
Election. The big question is whether any of the
rumoured tax cuts and changes on the horizon will help the
construction and built environment sector which, along with
the rest of the economy, is experiencing tough times.
The government’s annual housebuilding targets have
yet again failed to be met, and given the general state of
the economy it’s hard to see how this is going to change in
the near future. This is particularly true when you consider
the recent Competition & Markets Authority report into
the housebuilding market, which has raised ‘fundamental
concerns’ about the planning system and build quality of
new homes, which you can read more about on page 6.
But while things may seem gloomy on the surface, there
are still opportunities out there. We’ve taken an in-depth look
at the housing and healthcare sectors this month, bringing
you examples of some fantastic projects, where innovative
materials and new technologies have created some truly
inspiring buildings. We’ve been particularly impressed by
how the drive for energy efficiency is now sitting at the heart
of so many building projects.

CMA finds ‘fundamental concerns’ in Great
Britain’s housebuilding market
The Competition and Markets
Authority (CMA) has published
a report on the housebuilding
market in Great Britain – finding
the “complex and unpredictable”
planning system, and the limitations
of speculative private development,
responsible for the persistent underdelivery
of new homes.
The study also found substantial
concerns about estate management
charges – with homeowners often
facing high and unclear charges
for the management of facilities
such as roads, drainage, and green
spaces. Concerns have been found,
too, with the quality of some new
housing after the number of owners
reporting snagging issues increased
over the last 10 years.
The CMA has also opened an
investigation into the suspected
sharing of commercially sensitive
information by housebuilders which
could be influencing the build-out of
sites and the prices of new homes.
The investigation – under the
Competition Act 1998 – is being
conducted into Barratt, Bellway,
Berkeley, Bloor Homes, Persimmon,
Redrow, Taylor Wimpey, and Vistry.
The CMA has not reached any
conclusions as to whether or not
competition law has been infringed.
There are persistent shortfalls in
the number of homes built across
England, Scotland, and Wales, with
less than 250,000 built last year
across Great Britain.

HHIC releases guide on differing CO detector
requirements across the UK
Following several regulatory changes
across the different countries in the
UK, the Heating and Hotwater
Industry Council (HHIC) and the
Council of Gas Detection and
Environmental Monitoring have
launched a guide on carbon
monoxide (CO) detector requirements
across the UK.
As variation in CO legalisation
across England, Wales, Scotland and
Northern Ireland could cause
confusion, the guide has been
launched to provide the best practice
for each region.
Property owners must ensure that
CO detectors are present in each
property, in the appropriate locations
and in accordance with legislation and
related guidance. The guide highlights
the differing requirements including
the number of CO detectors required
in a property, the batteries that must
be used and where detectors must be
installed.
Kevin Lowe, Technical Manager of
the HHIC, said: “Following changes to
CO legislation made in the past year,
it’s crucial to be aware of the different
obligations across England, Wales,
Scotland and Northern Ireland. Our
guide will help [people] easily
understand the regulations they must
adhere to.”
The guide also features the
standards placed upon social and

Massive industrial fire destroys warehouse
A major fire at an industrial estate in Bridgend destroyed a
huge 20,000m 2 building used largely for warehousing,
sending plumes of smoke into the surrounding area. One
of the largest fires in Europe in recent times, the scale of
the blaze was immense, impacting a number of
businesses and highlighting gaps in fire safety measures.
The devastating fire broke out on 19 January in a
building largely housing a warehouse owned by the Owens
Group. This was also home to a number of businesses
ranging from a tyre company and storage facility to a
company selling paper products. The building was
completely destroyed and the blaze required 10 fire crews,
four water carriers and two aerial ladder platforms from the
South Wales Fire and Rescue Service.
Thankfully, there were no reported injuries in the blaze
but there were repercussions for businesses within the
warehouse, as well as adjacent businesses and colleges.
Iain Cox, Chair of Business Sprinkler Alliance, says the
building lacked a sprinkler system, and is campaigning for
the inclusion of such systems into warehousing units.
He says: “It’s important to point out that unless the
whole building was storage, automatic sprinklers would
not have been required from a Building Regulations
perspective. However, any partitions erected within the
building to separate units and changing uses within the
building were ineffective. It points to the fact that for such
buildings the unit of control is the entire building and not a
smaller compartment within it.”
Recent statistics reveal the average cost of a large
warehouse fire amounts to £5.9m, with at least one
occurring every working day in England alone. These
figures underscore the critical importance for businesses
to carefully consider the impact and consequences of fire.
Quickly stopping the spread of fire when it is first
detected is the best way to limit damage and minimise
costs and impacts. Sprinklers have been shown to
contain, control or extinguish fires in 99% of cases when
caused to operate.

Specifying roof protection?
Get your ducks in a row.

COVER EDITORIAL
TACKLING THE CAUSE AND EFFECT
OF CLIMATE CHANGE
CARLISLE Construction Materials, the global specialist in building envelope solutions
for roofs and facades, discusses the need for roofing systems that both address the
causes and reduce the impacts of climate change, highlighting how thermoplastic
polyolefin technology fits the bill on both counts.
The summer weather in the
recent past in the UK may
most accurately have been
described as a wash-out,
and the flooding belies the
evidence from across the world that the
planet is heating up at a speed that not
even the scientists who warned of a
climate crisis had anticipated.
Changing weather patterns present
huge challenges for the specification and
construction of our built environment.
Increasingly, the whole construction
delivery chain is looking for solutions
that deliver a circular approach to
sustainability. As Carlisle launches
the SURE-WELD TPO (thermoplastic
polyolefin) system in the UK, what
advantages can TPO demonstrate to
reduce a building’s impact and improve
its resilience to climate change?
The urban heat island effect
The most immediately obvious difference
between a TPO roofing membrane
and other single ply roofing systems is
the colour. TPO is a pale grey or white
roofing membrane which reflects heat,
preventing solar gain.
This heat absorption issue is a
phenomenon known as the urban heat
island effect, but it is not confined to
urban areas. It can also affect industrial
estates, logistics hubs, large hospital
complexes – any environment where
large expanses of roof have the potential
to absorb or reflect heat. It is a problem
that is growing exponentially, as the
level of urban density and the scale
of industrial and logistics buildings
increases.
While a heat-reflecting roof covering
such as SURE-WELD TPO is not a
complete solution to the urban heat
island effect on its own, it is a key
element of the role that the building
fabric can play in reducing this issue.
When specified in combination with
energy efficient building services and an
insulated building envelope that reduces
heating and cooling requirements, it
can form part of a robust environmental
strategy.
Robust performance
The flip side to the higher temperatures
the world is experiencing due to the
changing climate is the level of rainfall
we’re getting – which is also predicted to
increase in the coming years.
Waterproofing is the main purpose of
any roofing system, and any technology,
properly installed, should have that
fundamental principle at the heart of its
performance.
As best practice goals, however,
specifiers should also be looking for
waterproofing systems that enable the
project team to make the structure
watertight quickly. This reduces the
risk of leaks at seams or fixings, and
provides consistently high levels of
waterproofing performance throughout
an extended service life. For larger roofs,
a flexible membrane available in large
sheets enables the project team to make
the building watertight quickly, and both
TPO and EPDM systems are ideal in this
regard. Both Carlisle’s SURE-WELD TPO
system and Hertalan EPDM system are
suitable for installation using induction
technology, which not only enables a
quicker and simpler installation process,
but also means that the membrane can
be removed cleanly and easily from the
roof at the end of its service life.
Longevity is also an important element
of performance and environmental
credentials. TPO contains no plasticisers
and will not crack or blister over time,
retaining its elasticity and consistent
performance throughout its service life.
As an additional performance benefit,
the SURE-WELD TPO system has been
formulated with Octaguard XT weather
protection, an ingredient combining
U/V and temperature stabilisers, which
improves durability and flexibility.
Enhancing green credentials
Operators of large buildings, such
as logistics hubs and factories, are
increasingly aware of the need to invest
in environmental best practice as part
of their ESG commitment. They are also
cognisant of the operational cost and
resilience benefits of using renewable
energy, rather relying on the grid. As
a result, companies like Amazon are
installing solar panels at their sites.
TPO is an ideal partner for rooftop solar
PV, because it is robust enough to
support the installation and its reflective
properties help to maximise the potential
energy conversion of the panels.
Similarly, large roofs have the potential to
enhance biodiversity and embed green
space into development projects with
the specification of a green roof. Offering
excellent root resistance, TPO is also an
ideal waterproofing membrane for use in
green roof projects.

HOUSING
RENOVATE OR RELOCATE?
Dave Broxton, Managing Director at Bohle, explores how companies can capitalise
on the current trend for quality home renovations.
More homeowners are renovating their homes with a
view to the future, with a recent study from Houzz
finding that 62% of homeowners who had undertaken
renovations planned to stay in their property for 11 years
or more. An estimated one in 10 potential sellers are also
choosing to invest in quality renovations as opposed to moving
home, according to Your Mortgage Expert, citing the current
mortgage and housing market pressures as factors in their
decision.
This focus on improving, rather than moving, is a real
opportunity that specifiers can capitalise on. By offering highquality
and high-performance products that will stand the test
of time, businesses can increase their margins and also reduce
the likelihood of callbacks, which is a win-win scenario for
everyone.
Made to last
This long-term view is especially crucial in more skilled
renovations, where costs tend to be more of an investment
and products need to be installed to last. While a bedroom
can be transformed with a quick lick of paint, or a dining room
given a new style by re-furnishing, the cost and disruption
involved in a bathroom renovation means once it has been
designed, specified and installed, the chances are that the
bathroom will then be left alone for a considerable period of
time. Because of this, we are seeing people gravitate towards
higher value bathroom installations.
Aesthetics and ease
The Juna Shower Door Hinge for glass shower doors, for
example, features minimum gap dimensions to create a clean,
high-quality appearance. Other modern aesthetic features
include no visible screws, a practically continuous sealing
strip, and the above-average return angle of 20°, which closes
the glass door automatically. Tested to 100,000 cycles, the
Juna Shower Door Hinge is made from brass and stainless
steel with a load capacity of 50kg per pair – a necessary
requirement for ever larger shower doors. It is also supplied
with a five-year guarantee for peace of mind.
The Juna shower door hinge was also designed to be easy
to install, so that specifiers can choose it without worrying
about issues during the installation process. The zero-position
adjusting screw is easily accessible and enables convenient
adjustment: the clamping screws and the zero-position fixing
screw have uniform screw heads, which can all be tightened
with just one tool.
Furthermore, the centred mounting plate is designed to
perfectly locate the cover cap, which guarantees a firm and
precise fit.
Quality is king
Aside from the possible quality implications of a cheaper
alternative, there is also a rising consumer sentiment against
mass-manufactured, discount products. Perhaps a by-product
of the global focus around sustainability and ethical production,
67% of consumers now regard the behaviour of a company
as important as what it sells, according to research by Ernst &
Young.
The bulk of Bohle’s products are now manufactured in Europe
and distributed locally through our subsidiary network. They
are produced in an energy efficient manufacturing environment
that will become even more sustainable this year, when our
manufacturing site in Haan in Germany will generate most of
its energy via solar power, thanks to a substantial photovoltaic
installation.

AN ANCIENT MATERIAL IDEAL FOR
MODERN BUILDINGS
There is much to recommend clay bricks as a modern, sustainable building
material. Keith Aldis, CEO of the Brick Development Association, explores its
environmental credentials.
clay brick buildings rather than demolishing them, carbon
emissions are further reduced while preserving the architectural
heritage of the local area.
As a durable, reusable and recyclable material, clay brick is
one of the most carbon-friendly building options. Its resilience
over generations embodies sustainable design, saving carbon
and retaining the character of our built environment. A cradleto-cradle
mentality recognises the sustainability inherent in this
natural material.
However, current methods for assessing sustainability such
as Environmental Product Declarations (EPDs), often fail to
account for clay brick’s exceptional longevity. EPDs typically
use a limited 60-year study period, which fails to account for
the exceptional longevity of durable materials like clay brick.
As we have stated, the oldest fired bricks are over 6,000 years
old, demonstrating how clay bricks’ lifespan can exceed EPD
assumptions by over 98%.
Clay brick has proven its performance for thousands of
years. When compared to other forms of construction,
clay brick’s minimum active lifespan of 150 years sets
it apart. In fact, clay bricks can last much longer. Roman
structures such as the Pantheon were built using brick in
120AD and are still perfectly intact.
In the UK, present-day Cambridge is an excellent example of
a city built on clay brick, with many university buildings dating
back to the 1400s. The prevalence of Georgian-era brick
buildings that also continue to be used and appreciated across
the UK are testament to the durability of clay bricks. Clearly,
under the right circumstances, the evidence of clay brick’s
longevity is all around us.
Brick resilience
When compared to other building materials, clay bricks are
highly durable, stable and robust. It will not break down and,
in most environments, is completely impervious to anything.
Resilient to extremes of weather including flooding, clay
brick can withstand generations of wear and tear with little
or no upkeep. Non-flammable and non-combustible, clay
brick façades often survive fires structurally intact, enabling
renovation and reuse.
Cradle to cradle
Clay brick’s durability and resilience over time demonstrate
the importance of taking a cradle-to-cradle approach
when evaluating sustainability, and considering a product’s
environmental impact across its entire lifecycle from production
to use, maintenance, and reuse or recycling. With extensive
longevity, clay brick buildings prolong usable lifespan, resulting
in a lower carbon footprint per year of use. Clay brick can also
be reused and recycled indefinitely, avoiding waste. By reusing
This longevity drastically reduces clay brick’s carbon footprint
per year of use. While EPDs ignore lifespan beyond 60 years,
clay bricks endure for centuries. By underestimating the
extended lifespans of clay bricks, EPDs and the specifiers who
reference them lack crucial data on true carbon footprints.
Only an analysis accounting for longevity and recyclability will
capture the minimal carbon impact of clay brick across its full
lifecycle.
A local product
It’s important to highlight that clay brick is also a local product
for local communities – and has been that way for thousands
of years. When you consider that 85% of the bricks used in
the UK are manufactured here, it’s easy to see why we are a
country built on locally produced clay brick. Clay bricks from
UK brick manufacturers travel on average no more than 68
miles from factory to site. This short distance from factory
to construction site minimises economic and environmental
costs.
Thermal mass
Clay brick is also noted for its excellent thermal mass. This
ability to absorb, store and release heat energy helps to
regulate indoor temperatures and reduce energy consumption
for heating and cooling. This contributes to lower operational
carbon emissions, as the building requires less energy to
maintain comfortable temperatures throughout the year.
Clay bricks contain only natural elements such as clay, sand,
water, and air. No harmful toxic substances are added during
the brick-making process as they are made entirely from inert
materials that pose no health risk to humans. This results in
a healthy building material free of volatile organic compound
emissions, with no risk material throughout their lifecycle.

HOMEOWNER BUILDS DIY
FLOOD DEFENCE
A homeowner has been dubbed ‘Worcestershire’s answer to King Canute’ after
building his own flood defence for his property.
Located on the banks of the River
Severn, Nick Lupton’s converted
17 th century house has been
flooded 11 times since he and his wife
Annie moved into the property in 2016.
With the area prone to flooding during
periods of heavy rainfall, Nick knew he
needed to take action to protect his
property against further flood damage.
Nick explains: “Right from the moment
we bought this house, we knew exactly
what the flood risks were. We live in a
very beautiful part of the world, right
next to the River Severn, with one
drawback – we get flooded. Having
faced eight floods since 2019 alone, we
finally decided to take matters into our
own hands and build ourselves a wall to
protect our property.”
Self-built defences are common to
some properties in the region due to its
proximity to the River Severn. Having
considered some solutions used by
neighbours – such as layered masonry
which is tied together and filled with
concrete, Nick wanted a product that
was both hardy and reliable, and as
he’d be completing the bulk of the build
himself, easy to install.
One of the major
appeals with Stepoc,
for me, is that it
provides both vertical
and horizontal
reinforcement, giving
the product high levels
of structural integrity
The solution Nick decided upon was
Stepoc. Developed by clay and concrete
building materials manufacturer Ibstock,
Stepoc is a precast concrete block
retaining wall system which can be laid
dry. Available in a range of sizes, Nick
opted for Stepoc’s 200mm unit.
Nick explains: “One of the major
appeals with Stepoc, for me, is that it
provides both vertical and horizontal
reinforcement, giving the product high
levels of structural integrity – obviously
key for effective flood defence.”
In total, Nick required 110m 2 of Stepoc
blocks to build his protective wall, which
ranges in height from four to seven
courses. To ensure the project was as
cost effective as possible, Nick elected
to build most of the wall himself –
working with a contractor only to lay the
foundations and the first course.
To this end, the relative simplicity of the
Stepoc build process was another major
selling point. Nick continues: “Given the
scale of the wall needed to protect the
property, I knew that this wasn’t going
to be an inexpensive project. That’s why,
wherever possible, I was looking at ways
I could economise without compromising
on product quality. Thanks to Stepoc’s
easy to install functionality, I was able to
build much of the wall myself – a huge
help in managing the spend on the
project.”
Nick, who purchased his Stepoc via
Travis Perkins, also had access to
Ibstock’s in-house team of technical
experts and product datasheets, who
were able to provide him with in-depth
insights to ensure he was specifying the
best product for his requirements.
The build commenced in May 2023
and was completed in September, with
testing via Storm Babet occurring just
weeks later in October. In January 2024,
the wall faced its greatest challenge yet
when Storm Henk swept the country.
Nick concludes: “Almost as soon as the
wall was finished it was being tested
by some extreme weather. The flood
brought about by Storm Henk is one of
the severest we’ve experienced since
moving into this property, with water
levels nearly exceeding the record
flooding experienced in the area in 2020.
This was a great test for the wall and,
I’m happy to say, it has so far completely
stood up to the challenge.”
With more extreme rainfall, and thus
exacerbated risk of flooding, an
increasingly common part of the British
climate, investing in adequate flooding
defence is a growing concern for
property owners in vulnerable areas.
Ibstock’s Stepoc retaining walls are
uniquely designed to create a cascade
effect which ensures a smooth filling of
the pumped concrete, forcing out air
and eliminating segregation to create
walls which have immense compressive
and lateral strength.

HOUSING: CASE STUDY
2 COUNTIES CONSTRUCTION
REVIVES FORMER STABLES
A 16 th century hunting lodge has become a high-spec four-bedroom family home
following an extensive renovation. Specify & Build reports.
The Coach House forms part
of Hillhampton House estate,
originally the hunting lodge for
Witley Court, in Worcestershire. Built
in the 16 th century, the structure has
been extended several times over the
years and comprises many different
architectural styles.
Purchased with planning permission
for residential conversion, the owners
appointed local chartered architect Zebra
to manage the extensive renovation
of the Grade II* curtilage listed Coach
House.
“The building’s structure and fabric were
in danger of becoming deteriorated
but provided a great opportunity to
create a new usable environment,” says
Matthew Parsons, associate director and
chartered architectural technologist at
Zebra.
“The planning authority and English
Heritage were very particular about
the design of the building, and the
concept was based around converting
the spaces but only if the interventions
could be achieved without detrimental
alteration to the character of the
structure.”
To achieve this, the project required a
main contractor with the necessary skill
and experience to manage and deliver a
complex renovation of a listed building.
“2 Counties Construction had tendered
on a previous project and submitted
a professional response and so we
approached them for the Coach House,”
continues Matthew.
“Mark and his team provided a price
which was well thought through and
comprehensive, and they were able
to commence work within the client’s
timeframe. They were responsive to
queries relating to their proposal and
were willing to discuss details which
would make the project go smoother.
More importantly, they were human and
felt like a team we could work well with.”
A contemporary transformation
2 Counties Construction transformed
the disused brick built stable block
into a four-bed luxury family home with
contemporary design, using traditional
methods and materials.
The biggest challenge was combating
the damp. This is one of the reasons the
Worcester-based building contractor
used lime products to improve the finish
and durability of the structure, allowing
the walls to breathe. There were also
areas of traditional lathe and plaster
which had to be preserved.
Thermal efficiency was vital to the
success of the project, to create a warm
and energy efficient home. Multiple
measures were employed to achieve
this, including a thermally upgraded
roof. The groundworks also included
preparatory works for the installation of
an underground 10,000-litre oil storage
tank. This was particularly challenging
as the levels had to be accurate for the
boilers to perform.
To meet planning stipulations, certain
historic details had to be preserved or
re-worked into the renovated structure.
2 Counties Construction re-laid the blue
engineered brick floor, for example.
Being a stable, the original floor was
dished for drainage so the bricks were
dug up and laid flat to create a charming
and characterful floor in the kitchen.
Working with a specialist sub-contractor,
2 Counties Construction also replaced
sections of cornicing using a replica
mould.
The Coach House is ancillary to the
main house and as such, significant
external works were required. Alongside
extensive groundworks, 2 Counties
Construction remodelled the driveways
and courtyard and installed a sewerage
treatment plant. Due to the location and
nature of the property, the building firm
liaised with ecology and conservation
professionals to install bat lofts and
mitigation systems.
Matthew concludes: “2 Counties
Construction were professional, hardworking,
and attentive. They could
always be found on site, carrying out and
planning work. They had the resource
to be able to cope with the project and
respond to a changing brief and extra
requests, without complaint.”

FABRIC-FIRST DESIGN IS KEY TO
COMPLIANCE
Simon Blackham, Senior Technical Manager at Recticel Insulation, highlights how

31% more carbon efficient
than previous standards. Prioritising the
composition of the walls, floors and roof
reduces reliance on mechanical heating
and ventilation systems and creates
homes that use less fuel to run.
Low-carbon heating technologies such
as heat pumps have a part to play in

regulations
Case studies carried out on fabric-first
designed buildings found that fabric
insulation alone reduced heating demand
by up to 63%, according to a report by
Cardiff University on behalf of the Welsh
Government. This can be achieved
using widely available and cost-effective
insulation technologies together with
conscientious design principles. Highly
effective energy performance depends
on achieving good U-values in the walls,
floor and roof, as well as openings such
as windows and doors. To achieve
maximum performance and to ensure
airtightness targets are met, it is
important the insulation is specified and
installed properly to reduce instances of
thermal bridging.
The Part L amendments also create
stricter standards for extensions,
replacements, and upgrades to older
homes. However, a proportion of these
buildings will not be suitable for retrofit
and approaches may need to vary
from one dwelling to another. Thus,
a proper assessment and design is
always essential. By getting this aspect
right, heating demand in older buildings
retrofitted with quality insulation can be
reduced by up to 50% when compared
with the current housing average.
Looking to the future
These latest amendments are
considered a critical milestone toward

a transformative shift in the construction
industry’s approach to building homes.
It introduces several initiatives to ensure
that homes are constructed to meet the
required energy performance. These

process, where contractors are required
to document critical junctions via
geo-located digital photographs. This
transparency enables homeowners
to better understand how the as-built
Similar to the interim Part L regulations,
the FHS underscores the need for
improving 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
can lead to buildings falling short of
U-value requirements. Polyisocyanurate
(PIR) panels are regarded as a longterm
solution to address this energy
performance gap compared to mineral
PIR’s thermal performance also isn’t
compromised by its slim composition,
and requires less thickness to achieve
the same U-value as other insulation
materials. This benefit is particularly
valuable for specifiers 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 terraces and balconies where
space is limited and threshold levels are
an issue.
The Future Homes Standard places greater emphasis
on heat loss at junction details such as windows, which
is calculated using the PSI value method. Although

How PIR benefits performance
In performance and installation terms,
PIR insulation is ideal for fabric-first

PIR is a versatile product that delivers
consistent thermal performance and

pitched roofs and flat roofs over time.
With impressive lambda values as low
as 0.022W/mK, PIR insulation offers
excellent performance and quality in
relation to cost.

BUILDING RESILIENT CITIES
Modern cities require enhanced levels of infrastructure that can reduce risks and
respond to the increasing climate challenges. That is why the concept of urban
resilience is steadily growing in popularity. Sontay reports on how advanced
technologies can fortify the foundation of urban sustainability.
The vision of resilient and
sustainable cities has transcended
from aspirations to a necessity.
It is defined by the Resilient Cities
Network as “the capacity of individuals,
communities, institutions, businesses
and systems within a city to survive,
adapt and grow no matter what kind of
chronic stresses and acute shocks they
experience”.
Climate-resilient cities
Addressing the world’s climate
challenges requires proactive measures,
as the number of climate-related threats
such as rising sea levels, droughts and
intensified extreme weather events
escalate. As cities continue to grow in
number and size, the need to fortify
buildings against these challenges while
actively mitigating carbon emissions is
only becoming more urgent.
At the heart of climate resilience is
energy resilience, a fundamental pillar
in the construction of sustainable cities.
Transitioning towards greener energy
solutions that are centred around
people’s needs and with reduced carbon
footprints, is becoming paramount for
achieving climate resilience.
A resilient city is a smart city, and there
can be no smart cities without smart
buildings, which is why embracing the
latest technological advancements,
particularly in Building Management
Systems (BMS), becomes indispensable.
Building management systems
Smart technologies provide building
owners and managers with versatile
tools to navigate both internal and
external climates, while continuing to
strategise for sustained sustainability and
growth. In terms of energy consumption,
buildings stand as significant
contributors, with a considerable portion
being wasted. This reality underscores
the need for sustainable solutions
like BMS, particularly in buildings
aspiring for heightened environmental
consciousness.
As cities aspire toward modernity,
intelligence and resilience, the surge in
electricity demand could pose a threat
to structures such as the National Grid.
However, a BMS can provide a strategic
and sustainable alternative, minimising
overload on existing energy providers.
The functionality of BMS extends
across many tasks, encompassing the
monitoring and management of crucial
building systems such as ventilation,
lighting and heating. By harnessing
real-time data analytics, BMS enables
automatic adjustments for optimal
energy efficiency, including intelligent
reactions such as heating adjustments
based on occupancy. Building managers
can leverage this wealth of data to
intervene when required and ensure
ongoing building efficiency during
changing circumstances. A BMS can
also identify and alert building managers
to system faults or inefficiencies, preempting
potential escalations that
could prove costly, both financially and
environmentally.
Building smart with Sontay
Sontay provides sensing and peripheral
devices for any kind of building. With
an extensive range of products and a
team of experts, Sontay’s offering spans
monitoring and control across various
environmental categories – from air
quality and gas to temperature, air/water
flow, and occupancy levels. Notably, the
Sontay Open Range Application (SORA)
stands out for its wireless adaptability,
presenting an ideal solution for any
application, but particularly for older
buildings seeking modernisation with
less construction work involved.
Hospitals epitomise the critical
infrastructure within resilient cities,
yet much of the UK’s hospital stock is
housed in old buildings with antiquated
systems.
Due to the important services being
carried out within hospitals, they require
a smart solution that can work around
the busy hospital setting, rather than
causing unnecessary downtime. This
is where Sontay’s SORA range offers a
practical solution, facilitating seamless
integration and showing how BMS can
contribute tangibly to the realisation of
resilient urban landscapes.
Today’s reality demands infrastructure

DECARBONISING THE UK’S
SOCIAL HOUSING
The social housing sector is at the heart of an energy revolution in the UK. Lee
Caulfield, Head of Residential Specification at Baxi, outlines the possible approaches
to bringing down emissions across our social housing stock.
Social housing properties
comprise a wide variety of
complex needs and strict
budget constraints that
make enacting change a
real challenge. Striking the right balance
between residents’ fuel poverty and the
need for decarbonisation is a decision
that will have long-lasting consequences
and must not be taken lightly.
Older buildings are often inefficient
to heat, meaning the social housing
sector needs new solutions to solve
heritage problems. While it would be
easy to view this as a hurdle in the road
to energy efficiency, it should be seen
as an opportunity to design innovative
strategies using the newest technologies
to improve the energy performance of
historic social housing.
There will not be a one-size-fits-all
answer to this challenge, but it can be
approached holistically by considering
the end-user at its centre. A realistic
solution which considers funding and
the types of properties that require
upgrades, as well as encouraging social
housing providers to participate in the
drive towards sustainability, will be
required.
At present, it is estimated that there are
5.4 million social housing properties in

But there is funding available for green
upgrades through the Social Housing
Decarbonisation Fund (SHDF), where
£3.8 billion has been set aside for social
housing providers to claim over the
course of 10 years.
The process of decarbonisation can
begin by assessing a property and
defining the areas of energy waste, heat
loss, or other system inefficiencies. The
SHDF also provides an excellent starting
point for financing green upgrades.
The smallest of efforts can lead to
sizeable steps in the path towards
decarbonisation and sustainable,
affordable heating. With a long journey
still to go, many specifiers working on
social housing projects will want to know
where to start.
addition of generally small improvements
which will, in turn, negate the need
for more significant upgrades in
the future.
As well as planning for the
future, residents should be
educated about the steps
they can take to reduce
energy consumption. This
can help highlight how
small changes can have
a significantly positive
impact. For example,
the Energy Saving Trust
estimates that a 1°C rise in
thermostat temperature may
equal a 10% increase in heating
bills.
Welcoming innovation
Introducing add-ons that do not require
maintenance can then be an easy and
effective way of improving a system’s
performance. Adding devices such
as Flue Gas Heat Recovery (FGHR)
systems can bring down emissions
and provide a more cost-efficient and
sustainable heating solution.
To demonstrate, in a three-bed semidetached
house, the addition of FGHR
to a Baxi Assure 500 Combi 2 can
reduce annual carbon emissions by as
much as 268kg. As a result, this saves
between 37 and 50% of the gas used to
generate hot water annually by storing
heat that would have been lost. The
system then redirects this otherwise
wasted energy to preheating cold water.
Inventive solutions such as these can
reduce overall emissions, bring down
costs, and increase the quality of living
for tenants simultaneously.
Collaboration is key to completion
As the journey to decarbonisation
continues, larger upgrades will almost
certainly be necessary. The installation
of air source heat pumps (ASHPs),
introduction of heat networks for multioccupancy
properties and exploration
of hybrid systems are all part of effective
forward planning.
The critical evaluation of options and
working closely with manufacturers who
offer energy-efficient and low-carbon
heating solutions is key. A collaborative
effort means that social housing
specifiers have the correct solution ready
for each individual property and project.
The future frontier
As the climate crisis worsens and
net zero targets get closer, specifiers
have an opportunity to place the
social housing market at the forefront
of innovation. The UK’s existing
housing stock’s energy efficiency must
be harnessed to progress towards
sustainability.
Social housing leaders and associations
can make use of valuable support
through working with heating experts
such as those at Baxi. Through the
application of heating expertise in
combination with social housing needs,
the target of an environmentally and
economically sustainable future for social
housing is in sight.

Fabric first
Focusing on the fabric of a building is
a good place to start on the path to
reducing emissions and energy costs.
This should not just be about retrofitting
but about creating homes that are

modernising windows, making sure
there are sufficient levels of insulation
throughout, and that rooms are draftfree.
It is also important that end users
are kept up to date on how to correctly
operate temperature control devices,
such as TRVs, to optimise energy
efficiency.

SPECIAL FEATURE
TRUST ACCREDITATION TO CHOOSE
THE RIGHT MATERIALS
Don & Low explores the added value specifiers can make the most of when working
with an accredited construction membrane manufacturer.
Choosing the right building
materials is crucial for ensuring a
building’s integrity, performance
and durability. But when it comes to
construction membranes, it’s important
to remember that they are not all the
same. Picking the best available option
can have a significant impact – and that
is where the true strength of accredited
construction membranes kicks in.
Working with an accredited membrane
manufacturer gives specifiers, architects,
builders and contractors several
advantages, such as consistent quality
and supply, which are essential to the
successful, timely completion of any
construction project. Accreditation
proves manufacturers’ dedication to
upholding industry standards and
regulations, ensuring the reliability of their
membranes. It’s no surprise then that
certain projects, such as governmentrelated
initiatives or social housing, make
accreditations a necessity.
As an added bonus, environmental
accreditation shows a commitment to
supporting carbon footprint reduction
efforts – and a strong sense of corporate
responsibility. All players in the supply
chain can rest easy knowing that an
accredited manufacturer and their
products have undergone independent
checks, audits and approvals. This
trustworthiness is usually matched with
excellent technical support, as is the
case with Don & Low.
Cracking the code of membrane
accreditation
Accreditation goes beyond being a mere
stamp of approval. It involves a thorough
evaluation carried out by independent
third-party agencies. Thus, when it
comes to construction membranes,
professionals should keep an eye out for
the following:
• ISO9001. The globally recognised
quality system indicates that a
manufacturer’s entire operations
have been independently evaluated
and audited. Don & Low maintains
consistency in every aspect of its
business, from materials inbound to
production, delivery, billing and record
keeping.
• British Board of Agrément (BBA)
Certification. An industry recognised
standard that details construction
membrane specification and use. Don
& Low holds this for all of its applicable
construction membranes.
• Supply Chain Sustainability School
(SCSS). Works within the construction
industry to enhance the sector’s
environmental performance and
ultimately reduce the carbon footprint.
Don & Low holds the highest (Gold)
membership with the school.
• Structural Timber Association
(STA). An organisation formed to
influence legislation and regulation
within the structural timber sector.
Don & Low’s membership reflects the
company’s commitment to support
this essential industry, which will help
the UK fulfil its newbuild housing target
through offsite manufacturing.
• Environmental Product Declaration
(EPD). Demonstrating the amount
of CO 2
generated in membranes
production. As the UK’s only
vertically integrated manufacturer
of construction membranes, Don &
Low is able to track the products’
manufacturing process from polymer
pellets to finished membranes and
calculate the CO 2
produced. Notably,
Don & Low also uses a minimum

ENHANCING EFFICIENCY IN
HEALTHCARE SETTINGS
Jason Hartigan, Specification Sales Manager at Wilo UK, underscores the crucial
role of correctly specified and maintained pumps in achieving the NHS’ ambitious
net zero goals.
The pursuit of net-zero targets
within the NHS is a formidable
challenge, particularly when
it comes to navigating the
safety-critical components of
plant rooms and pumps, where precision
and reliability are paramount.
Hospitals and healthcare facilities can
be likened to humans. Much like how
we rely on our hearts to pump blood
around our bodies, hospitals also rely
on plant rooms, which contain intricate
networks of circulating and booster
pumps, responsible for distributing hot
and cold water through the hospital.
The failure of these plant rooms and
pumps is not an option, as it could
lead to catastrophic consequences,
disrupting operations, closing surgical
wards, and creating unsafe conditions
for patients and staff. Given the current
strain on the NHS and the imperative
to reduce carbon emissions wherever
possible, ensuring the efficiency and
reliability of these systems is paramount.
Apart from safety considerations, the
operational efficiency of plant rooms
is equally essential. With the NHS
contributing a significant share of the
UK’s carbon emissions, efforts to bring
down these figures are crucial if the
NHS is to achieve its declared ambition
to be net zero by 2045.
A challenge for asset managers
The challenge lies in the regular and

specialised monitoring required to
maintain optimal operational levels
for plant rooms and pumps. Estate
managers, often burdened with a
myriad of tasks, may overlook individual
pumps’ health, leading to potential
failures. Complicating matters further,
there may be a lack of up-to-date
asset lists, making it challenging to
track equipment installation and service
needs.
Navigating plant rooms is tough not
only due to historical knowledge gaps
but also because these areas are often
difficult to access.
Some plant rooms may be perched
on top of hospitals or tucked away in
inaccessible locations, posing logistical
challenges for auditing and replacing
pumps. Careful planning, consideration,
and often complex procedures are
required for demounting, removing, and
installing new pumps in such areas,
especially if they are heavy and hard to
carry.
Given these complexities, involving
pump industry specialists becomes
imperative to establish clear
maintenance schedules in healthcare
settings. Suppliers like Wilo, for
instance, can offer expertise in how
to consolidate existing assets, create
comprehensive asset lists, and
deploy effective planned preventative
maintenance (PPM) solutions.
A simple, yet efficient PPM schedule
is the traffic light system, which ranks
equipment from red to green. Quite
simply, equipment ranked as red needs
urgent attention, amber may require
attention soon, and green means the
pumps are in good health. Adopted
by Wilo, these schedules assist with
arranging maintenance routines and
keeping on top of documentation, while
lessening any sudden and unforeseen
downtime. Remote monitoring,
preventative maintenance and service
agreements can also be offered, taking
the pain away from estate managers
completely.
Importantly, when finding suppliers
to work with, there should be an

understanding that plant rooms are
sensitive areas. Any third-party staff
should undertake the correct training
and be certified to enter these areas,
so as not to cause any additional
problems. Seeking industry specialists
that have been through CSCS Training
and hold all the right qualifications is
key.
The smart way to NHS net zero
Collaboration between estate managers
and pump manufacturers can also
leverage smart pump technology to
make significant strides toward the
NHS’ net-zero goals.
Smart pumps, exemplified by products
like the Wilo-Stratos MAXO, not only
facilitate the movement of water but
also contribute to immediate energy
savings through intelligent, automated
operations. These pumps ‘learn’ the
operational characteristics of heating or
cooling systems, adapting in real-time
to demands and working synergistically
with other building services. Smart
functions provide detailed data to
estate managers, offering insights into
system health and enabling proactive
maintenance.
To ensure pumps are working to their
highest efficiency, performance data,
alerts, warnings, and notifications are
now readily available and can ensure
systems are always maintained. The
latest in smart pump technology
also provides information on heat
flow, cooling flow and volume flow.
Combining this data with other smart
systems provides insight into usage
patterns, resulting in better-regulated
indoor climate control that keeps power
and water usage to a minimum while
also reducing costs.
Manufacturers can assist in specifying
the right pumps and forecasting energy
and cost savings, supporting the NHS
in achieving its net-zero ambitions.
Wilo, for example, offers energy audits
to determine return on investment and
payback periods.
Recognising the safety-critical nature of
plant rooms and pumps in healthcare
settings, a concerted effort from
both internal managers and external
specialists is essential. The holistic use
of smart pump technology allows for the
collection and analysis of crucial data,
contributing to significant cost, energy,
and water savings, thus propelling the
NHS closer to its net zero aspirations.

REHAU PROVIDES THE CURE FOR
EPSOM HOSPITAL
When Epsom Hospital’s emergency department was in need of energy efficiency
upgrades during the peak of the global pandemic, seamless collaboration was
required between all parties. Specify & Build reports.
Epsom Hospital in Surrey provides
services spanning accident and
emergency, diagnoses and more
to the people of its namesake borough.
As a critical piece of infrastructure, its
continued operation is vital to the health
and wellbeing of the local community,
with this proven truer than ever during
the COVID-19 pandemic. However, like
any long-serving site, upgrades to the
building’s fabric would eventually be
necessary for it to remain operational.
“Getting projects across the line in a
live hospital environment is a challenge
at the best of times, let alone during a
global pandemic,” begins Dan Kocev,
Project Manager at Epsom and St.
Helier University Hospital’s NHS Trust.
“However, vital energy efficiency
upgrades were necessary to bring the
site into the 21 st century and ensure that
it is able to continue providing the best
possible environment for care.”
Natanael Florut, Project Commissioning
Manager at the NHS Trust, adds: “We
had some old timber screens and
windows that simply weren’t up to
scratch in terms of energy efficiency. I’d
previously worked with REHAU products
and know their quality. While choosing
something like REHAU’s curtain walling
was quite straightforward, I knew that
the installation would be something else
entirely, especially as our database did
not have too many technical records
from when the hospital was initially built.”
REHAU was designated the appointed
supplier and critical infrastructure
specialist Hanevo was brought on
board to facilitate the design and build.
JM Aluminium was then awarded the
installation contract based on a list of
recommended installers and fabricators
provided by REHAU.
Noel Hanley, Executive Chairman at
Hanevo, says: “Working in critical
infrastructure means that we’re no
stranger to complex projects, but we
knew that this installation would be
difficult even by our own standards.
However, through close collaboration
with REHAU and the other project
partners we were able to come up with
a design that we were confident would
work.
“Kevin O’Neill, REHAU’s Commercial
Manager, helped out with the drawings
and window specification, and ensured
that the whole project was compliant
with building regulations. The section
we were replacing backed onto critical
operating theatres and quiet rooms
that would remain in use during the
installation, so the plan was to complete
the removal screen-by-screen. This
would also help keep the site protected
from the elements as we worked through
the winter.”
With the stage set for the installation,
it fell on JM Aluminium to put the plan
into action. “This was one of the most

ambitious projects we’ve ever taken
on, but comprehensive planning and
collaboration gave us confidence that
we could get the job done,” explains
Director David Morant. “The new curtain
walling was to be installed over a live
ambulance bay and main pedestrian
thoroughfare, requiring comprehensive
health and safety assessments. It
was clear that we’d need a specialist
system to get the profiles up safely.
We were able to work closely with
London Network Scaffolding to design
a bespoke hydraulic and mechanical
system, adapting the top of the
scaffolding and fitting an electric hoist to
raise the panels up through the middle.”
As well as the complex curtain walling,
the project also saw the installation of
20 TOTAL70 windows in a foil wood
grain finish. All in all, the project took 16
weeks, beginning in spring 2022 and
concluding in the winter.
Kevin concludes: “Collaboration can
often be a buzzword across the industry,
but I don’t think I’ve worked on a project
that epitomises it more than this. The
outcome simply wouldn’t have been
possible without the hard work and
adaptability of all of our stakeholders,
from design through to installation.
Minimising disruption was our main
priority over the course of the project,
and the NHS has told us that it was
enamoured with the lack of complaints
they received.”

THE IMPORTANCE OF
ANTIBACTERIAL SURFACES
George Emms, Specification Sales Leader at Polyrey, part of Wilsonart UK, explains what
must be considered when specifying surfaces for the modern healthcare estate.
Given the ongoing need for
healthcare providers to
balance form with function,
surfaces are an area
where estate stakeholders
can make efficiency gains, while also
ensuring cleanability, antimicrobial
protection and durability in line with
rigorous standards.
The primary function of the healthcare
estate is to improve patient outcomes.
All design, wherever possible, should
be geared towards this aim – providing
care and comfort in an environment
that is effective, safe and operationally
efficient. Each aspect of a modern built
environment contributes towards this,
whether directly or indirectly. Indeed,
beyond the clinical aspect, it is important
for patients and providers alike to be in a
comfortable and convenient setting if the
best outcomes are to be achieved.
From the waiting room to the operating
theatre, all surface coverings used in
healthcare must meet rigorous standards
around cleanability and durability.
This includes acting as a safeguard
against the risk of infectious agents and
Healthcare-Associated Infections (HAIs).
Engineered surfaces such as melamine
faced chipboard (MFC), high-pressure
laminate (HPL) and compact laminate
are key.
It is with this in mind that the area of
microbial protection must be explored.
Currently, all surfaces must be selected
with hygiene management and the
prevention of bacterial proliferation
in mind. This includes ensuring any
specified products are hardwearing
without requiring additional protective
coatings such as varnish or paint, and
that they are easy to maintain.
Given the requisite emphasis on
cleanliness, surfaces should be
resistant to a large variety of sanitation
procedures. For example, they must
be able to withstand intensive cleaning
procedures such as bio cleaning or
disinfection with hydrogen peroxide,
while also being resistant to a large
variety of cleaning products.
Hygienic vs. antibacterial
There is an important distinction between
coverings that are classed as hygienic
and those designated antibacterial.
While the former passively limits bacterial
proliferation, the latter actively assists
toward this aim. While all laminate
surfaces will generally be considered
hygienic, not every type of surface can
be classed as antibacterial.
Whether used in a decorative or
technical context, antibacterial laminate
panels are designed to destroy 99.9%
of bacteria within 24 hours. This is
made possible due to enhanced silver
ion protection being integrated into the
material during the resin impregnation
stage of the manufacturing process.
Consequently, this benefit is enmeshed
within the product, meaning its effect
will not deteriorate over time due
to expected wear and tear within
the hospital environment. When
complemented with the rigorous cleaning
practices expected in healthcare estates,
antibacterial panels can provide an
important marginal gain toward infection
control and patient safety.
Rigorous testing
These solutions are currently offered by
Polyrey due to its work with SANITIZED
AG, a producer of antimicrobial hygiene
function and material protection for
textiles and polymers. SANITIZED AG’s
performance certificate is renewed every
year following rigorous laboratory testing.
This has been integrated into Polyrey’s
in-house processes to ensure
antibacterial grade products including
MFC, HPL and compact laminate are
included as standard without additional
costs or manufacturing delays. It is
certified as food-safe, skin-safe and,
when combined with the properties
of water-repellent laminate materials,
prevents moulds and bacteria from
proliferating.
Additionally, the silver ions used within
the material are not soluble, nonmigratory,
non-allergen and do not lead
to respiratory effects, so they are not
dangerous for patients or the healthcare
environment. As a result, surface
cleanliness can be enhanced and HAI
risks mitigated.

HOSPITALS, HEALTHCARE AND THE
LOW CARBON HOT WATER
CHALLENGE
The NHS has made a commitment to become the world’s first net-zero national
health service. With NHS estates and facilities playing a critical part in achieving this
ambition, Andy Green, Technical Director at Baxi, discusses the options for generating
safe, reliable and efficient hot water.
As part of its commitment
to tackling climate change,
the NHS has set ambitious
targets for reaching net zero
from its directly controlled
emissions by 2040, and the emissions
it can influence by 2045. Achieving low
carbon hot water generation is one of
the areas identified for achieving this
target.
Given the high demand for hot water
that is frequently associated with
healthcare premises – from comfortable
conditions and catering to in-house
sterilisation and laundry – this service is
a clear priority for efficiency. But it’s one
that comes with certain challenges.
First and foremost is the need to
prioritise patient safety and wellbeing.
Ensuring an adequate, reliable hot water
supply is key to the whole operation,
creating comfortable conditions for
patients and staff, maintaining clinical
standards, as well as being essential for
treatment purposes.
Related to this is the need to implement
measures to prevent the build-up of
waterborne pathogens, mostly related
to the control of legionella bacteria, in
the hot water system. To reduce the
risk of legionella, the Health and Safety
Executive (HSE) advises that domestic
hot water (DHW) should be stored at
a temperature of at least 60°C and
distributed so that it reaches 55°C at
the point of use in healthcare premises.
As the risk of patient scalding or burning
increases when water temperatures
are too high, a further consideration is
temperature control, which needs to be
provided at hot water outlets to protect
patient safety.
The Government has
identified heat pumps
as one of the favoured
technologies to achieve
net-zero buildings
The vast scale of the NHS estate, the
diversity of its buildings and differing
heating systems add to the complexity
of the challenge facing NHS estates and
facilities managers. Our focus here is on
newbuild net-zero carbon hospital and
healthcare buildings, and the design
strategies for their hot water systems.
The role of heat pumps
The Government has identified
heat pumps as one of the favoured
technologies to achieve net-zero
buildings. Certainly, in new hospitals and
NHS buildings, heat pumps will play a
key role in achieving low-carbon heating
and hot water.
Using refrigerant technology is an
attractive proposition for generating lowcarbon
heat as the potential efficiency
of air source heat pumps (ASHP) can be
up to 400% in many cases. This means
that for every 1kWh of electricity used to
run the heat pump, you get up to 4kWh
of heat output.
A number of logistical factors will
need to be considered at the project’s
outset, including the available space
and budget. The electrical capacity of
the site will be a further consideration,
especially where EV charging points
are in place. Your chosen manufacturer
should be able to advise on the options
36
www.specifyandbuild.co.uk \\ March 2024
as well as the latest technologies and
designs.
ASHP design options for DHW
When considering DHW generation and
the specific requirements in hygienecritical
healthcare environments, there
are a number of ways in which ASHPs
can be used.
Low-temperature ASHPs can be used
with direct electric water heaters in
an all-electric approach to raise the
DHW to safe temperatures. As this
approach would involve higher volumes
of stored DHW, it is important to take
into account the available space and
the weight of the larger cylinders –
particularly when dealing with rooftop or
non-basement plant rooms. Additional
forms of legionella control within the
larger volumes of stored water will
also need careful monitoring and
management.
Another option is high-temperature
ASHPs, which are capable of delivering
the high flow temperatures required
to meet the design temperature for
sanitary hot water. The advantage of
using high-temperature heat pumps is
that it avoids the need for an alternative
form of technology to store the DHW
above legionella temperatures.
This brings greater design flexibility
as less space is required, making for
a much simpler design and easier
installation. However, it’s important to
note that the coefficient of performance
of heat pumps drops off at higher
temperatures, affecting the real-world
efficiency and operating costs.
Point-of-use solutions
Point-of-use electric water heaters
should also be considered as an
efficient solution to the need for
immediate supply of sanitary hot water
in hospitals and GP surgeries, as they
only generate energy when required.
Installing a point-of-use water heater
like the Heatrae Sadia Multipoint
that incorporates anti-legionella
functionality, water pasteurisation and
anti-tamper design, will ensure that
water is adequately stored, cycled and
distributed.
Calculating embodied carbon
Net-zero targets mean that specifiers
must increasingly evaluate the
embodied carbon levels associated with
the manufacture of a product, as well its
operational performance. This includes
the carbon embodied in its installation,
transportation, maintenance, repair,
replacement and end of life.
To make it quicker and easier for
specifiers to evaluate and select
equipment with lower embodied carbon,
sustainably minded manufacturers
now provide this data on their
products. Baxi, for example, offers
free CIBSE Technical Memorandum 65
Embodied carbon in building services
calculation documents for its Heatrae
Sadia hot water solutions, with full
Environmental Product Declaration
(EPD) documents to be made available
for all new products – including the new
commercial heat pump range.
There are any number of options to
generate sanitary low-carbon hot
water in new hospital and healthcare
buildings. But achieving an efficient
service while avoiding the risks
associated with hot water provision
can be a complex challenge. This
is where early conversations with
your manufacturer of choice can be
beneficial, ensuring that you specify the
best possible products for your project.

KEY STEPS TO CREATING A SAFE
BATHROOM SPACE
Housing providers hold a responsibility to deliver reliable and inclusive homes. Karen
Wise, Head of Product Management at Triton Showers, outlines the fundamental
steps to creating a safe bathroom space.
water temperature. While hot water
poses a risk to us all, the effects
can be more severe for vulnerable
demographics, such as elderly residents
and those with physical or sensory
impairments.
Regulations state that 46°C should be
the maximum temperature of water
produced by a tap, yet the British
Burns Association recommends that
it should not exceed 37.5°C and
extra precautions should be taken for
vulnerable occupants.
We all want to feel safe in our
homes, and this is particularly
important within the spaces
we use regularly. In accordance with
the Decent Homes Standard, which
sets minimum standards for social
housing, bathroom appliances, pipework
and sanitaryware must not be more
than 30 years old. Therefore, when the
time for replacement comes around,
understanding how to provide an
updated space that preserves end-user
safety is crucial.
The Decent Homes guidance specifies
the need for an appropriately located
bathroom and WC that has adequate
space and a suitable layout. Maximising
the potential of limited space is a familiar
challenge to housing providers, and
overcoming layout constraints in the
bathroom can be achieved in several
ways, such as by specifying a shower
instead of a bath to save space.
For those with mobility issues, wet
rooms can offer a simple yet functional
design. By not needing to make room
for a shower enclosure or raised shower
tray, a wet room design can also be
practical when planning a space.
Ensuring there is sufficient drainage,
however, is just as important to
maximise usability and safety across the
generations.
Preventing slips and falls
As one of the most frequently used
rooms in the house, slips and falls
when exiting bathtubs and showers
consistently rank among the most
common cause of accidents in the
home.
Here, installing a grab bar will help users
maintain balance and navigate areas
with slip hazards. While this feature
is sometimes overlooked due to the
misconception of creating a clinicallooking
area, there are options that
maintain aesthetics while providing
added functionality. Weight-bearing
riser rails, for example, provide discreet
support without sacrificing style.
Evacuating wastewater from showers
where gravity is unable to do so is
another essential consideration. To
support housing providers, Triton has
developed Bluetooth compatibility with
its Omnicare Design and Omnicare
Ultra Plus electric care showers. Where
gravity drainage is not suitable, these
inclusive solutions allow for automatic,
easier pairing with a Whale Instant Match
Pump.
Getting the right temperature
Perhaps one of the most serious
considerations when it comes to
bathroom safety is maintaining a safe
Correctly positioning the showerhead is
another important step in lowering the
risk of injury. The further the showerhead
is placed away from the user, the cooler
the water flow will be. For functional and
care reasons, however, older users and
those with mobility issues are more likely
to be seated when showering, and if
the showerhead is positioned too high
then water may feel noticeably cold. This
can be avoided by carefully considering
the height of the showerhead in relation
to where the person will be positioned
when showering – and offering flexibility
to cater to both seated and standing
scenarios.
Further considerations
Specifiers are being encouraged to
choose products with credentials
and certifications, such as the BEAB
Care Mark, a stamp of recognition
that provides specifiers with peace of
mind that a shower is tried, tested and
trusted. Triton’s Omnicare range is both
BEAB Care Mark approved and RNIB
accredited, supplying a simple operation
that prioritises the independence and
wellbeing of end users.
Carefully specified bathroom designs
can not only create a space that ensures
independence and security, but also
offer a stylish and comfortable look. It is
essential that specification remains userfocused
by designing areas that are safe
both now and in years to come.

BATHROOM TRENDS HIGHLIGHT
STYLE AND FUNCTIONALITY
Bathrooms have evolved into havens of relaxation and style, with the latest design
trends focusing on personality, functionality and luxury. Ben Bryden, Sales and
Marketing Director for RAK Ceramics UK, looks at how to incorporate these trends
into new projects.
for bathrooms. This is not to the detriment of metallics, as
brushed brass, nickel and even gold add an air of opulence
and timeless grandeur to the bathroom.
Colours
There has been a notable shift in recent bathroom design
trends towards embracing colour as a means of adding
personality, warmth and visual interest to these spaces. While
the all-white bathroom has long been a classic choice for its
versatility, homeowners and designers alike are increasingly
drawn to the idea of incorporating colour to create more
dynamic and personalised bathroom environments.
Neutral and earthy tones continue to be a timeless choice
for bathroom colour schemes, offering versatility and
sophistication. Shades of beige, taupe and warm grey create
a harmonious backdrop that pairs well with a variety of design
styles, from modern to rustic. Neutral colours also have a
timeless quality that can adapt to changing trends.
Small bathrooms
This move towards spa-like bathroom design, creating a
calm oasis in the centre of our busy lives, is not limited to
large bathrooms. Designing a small bathroom doesn’t mean
compromising on style. In fact, the latest trends offer plenty of
opportunities to make a big impact in compact spaces. One
popular approach is to maximise vertical space by installing
tall cabinets or shelving units to provide ample storage without
taking up valuable floor space.
In recent years there has been a significant shift towards
natural and sustainable materials in bathroom design.
Materials like wood, stone and concrete are gaining
popularity for their earthy appeal and timeless elegance. Wood
accents, whether in the form of vanities, shelving or flooring,
add warmth and texture to the space and create a spa-like
atmosphere.
From earthy textures to botanical motifs, incorporating natureinspired
materials adds warmth, tranquillity, and a sense of
connection to the outdoors. Natural stone-inspired surfaces
are particularly on trend, not only for countertops and flooring
but also for shower walls, accent walls, and even sinks.
Mirroring the unique characteristics of such materials, porcelain
surfaces add a layer of durability and ease of cleaning
too, offering the best of all worlds in the busy bathroom
environment.
Additionally, matte black fixtures and hardware continue to
reign supreme, providing a striking contrast against lighter
backgrounds while adding a touch of modern sophistication.
The matte finish not only looks sleek but also resists
fingerprints and water spots, making it a practical choice
Opting for large-format tiles can visually expand the room,
creating the illusion of more space. Lighter colour palettes,
such as soft whites, pale greys, and light blues, reflect light and
make the room feel airy and open.
Additionally, clever use of mirrors can enhance the sense of
space and light in small bathrooms. Mirrored cabinets not only
provide storage but also bounce light around the room, making
it feel larger and more inviting.
Strike a balance
When incorporating the latest bathroom trends, it’s essential
to strike a balance between style and functionality. Start by
identifying the client’s preferences and lifestyle needs, then
tailor the design to suit their taste and requirements.
Consider mixing different materials and finishes to add visual
interest and depth to the space. For example, pair a marble
countertop with matte black taps for a sophisticated, yet
contemporary look. Then, you can experiment with textures,
such as sleek porcelain, to create contrast and tactile appeal.

MAKE THE MOST OF SMALL
KITCHEN SPACES
Willi Bruckbauer, Founder and CEO of BORA, looks at how choosing the right
appliances can help make us feel good about our kitchens, regardless of their size.
It’s easy to fall into the trap of
believing that every kitchen is a
sprawling, open-plan haven of space
and light. However, kitchens are
often compact, challenging, and
require innovative solutions to make
them both practical and aesthetically
pleasing. Despite the constraints of
limited space, the desire for a multifunctional
kitchen remains a priority
for many and, with thoughtful design,
even compact kitchens can be highly
functional and stylish.
Designing small kitchens means focusing
on maximising space efficiency without
compromising on performance or
aesthetics. This is based on several key
principles. Firstly, streamlined design;
minimalist design concepts prioritise
clean lines and clutter-free surfaces.
By reducing visual clutter and opting
for sleek, space-saving solutions,
small kitchens can feel more open and
spacious.
Flexibility is also key in small kitchen
design, with a need for modular or
customisable storage solutions that can
adapt to the specific needs of the space.
By incorporating elements such as pullout
shelves, adjustable racks and folddown
surfaces, every inch of available
space can be optimised and enjoyed.
Effective kitchen design for small spaces
goes beyond the visible, including
incorporating smart technology. From
energy-efficient appliances to intuitive
controls and automation features,
leveraging technology can enhance both
the functionality and user experience of a
small kitchen.
And, of course, the importance of
natural light can never be overlooked.
Well-placed windows, skylights, or
strategically positioned mirrors can help
to visually expand the space and create
a brighter, more inviting atmosphere.
Unobtrusive task lighting is another
essential, particularly in a kitchen that
is used for a variety of functions, from
food prep to home working, socialising

The founders decided to equip the

BORA S Pure induction cooktop and the
BORA X BO steam oven were chosen
to offer maximum performance without
compromising on convenience – the
perfect fit for Vagabundo’s philosophy.
There is no cooker hood to interfere with
the views of nature through the large

The team was impressed with the BORA
X BO’s qualities and performance.
“When we tested the steam oven for
the first time, we were thrilled that our
roasted vegetables were ready after just
12 minutes,” recalls Andreas.
The BORA X BO is a steamer and oven
rolled into one appliance. The steam
oven offers professional technology
for the domestic kitchen, with a steam

with the activated charcoal odour filter
it keeps the kitchen full of fresh air,
ensures a clear view and prevents steam
from escaping when the door is opened.

Mira Showers has introduced the new Mira Select Flex
– a mixer shower designed in partnership with the Royal
National Institute of Blind People (RNIB) to support a wide
range of accessibility needs.
This update to the Mira Select range uses cutting-edge
technology to offer inclusivity and sustainability, setting new
standards in shower design and functionality.
Mira Select Flex supports users with a wide range of
accessibility needs, including those with limited visual
acuity, dexterity, or mobility, as well as vulnerable users.
Developed specifically for aid and adaptation installations
and using the same inclusive design principles as the
Mira Advance, Mira Select Flex enables more confident
independent showering and easier assisted care showering.
Robin Spinks, Head of Inclusive Design at RNIB, said:
“We’re delighted to have had the opportunity to work with
Mira on the Select project. What we’ve really seen here is
a company who’ve been willing to ask questions, to listen
to users, to consult with expert organisations, and then to
take those findings and actually integrate them into the
design process so that what comes out at the other end
is a thoughtfully designed, inclusive and pleasant to use
product.”
The Mira Select Flex is the only RNIB ‘Tried and Tested’
accredited mixer shower. The simple push-button actuation
negates the need to adjust temperature and flow control
every time the shower is used, making it far easier to
operate, particularly where assisted showering is required.
The shower’s detents and visuals have been developed
in conjunction with the RNIB to ensure that it is optimised
for those with visual impairments. The high contrast colours
used, along with an anti-reflective surface makes showering
controls more visible, and raised icons and tactile graphics
have also been incorporated.
SELECT FLEX OFFERS AN ENHANCED
ACCESSIBLE SHOWER EXPERIENCE
Ergonomic controls, including an easy-grip loop-handle
lever for temperature and a lever for flow adjustment, plus
audible feedback, ensure the shower is easily handled by all
users.

HEATING AND
VENTILATION
SPECIFYING FOR FUTURE
VENTILATION COMPLIANCE
When specifying a new ventilation system, it is important to bear in mind future
compliance with the TR19 guidance document. Gary Nicholls, Managing Director of
Swiftclean and co-author of TR19, explains.
When specifying a ventilation
ductwork system, it is vital
to remember that, in future,
it must be professionally cleaned in
compliance with the TR19 guidance
document on ventilation hygiene, issued
by the Building Engineering Services
Association (BESA).
TR19 requires ventilation systems to
be classified as high, medium or low,
according to the areas that they serve
and the degree of usage to which
they are put. Large buildings, such
as hospitals, may have systems with
varying classifications; operating theatres
will be high; rarely frequented boiler
rooms or plant rooms will be low; while
the majority of facilities will be classified
as medium. TR19 contains helpful tables
which set out the intervals at which
ventilation systems should be cleaned
according to their classification and
usage.
However, to ensure that TR19 is followed
and ventilation systems are professionally
cleaned at their recommended intervals,
it is essential that ventilation cleaning
technicians can access the full length
of each system. This is where problems
can arise. DW/144: Specification for
Sheet Metal Ductwork, the specification
for the design and construction of
metal ductwork, does not require the
same frequency of access points for
the construction of ductwork as TR19
requires for its ongoing compliance.
TR19 currently requires that there should
be access points or hatches every
three metres, while DW/144 is less
prescriptive. Advocates of hygiene in
ventilation systems already in operation
have, through practical experience,
moved ahead of the theory of designing
and building them. Some fabricators
have been observant of the needs of
TR19 and started to specify and design
according to its recommendations.
Others have lagged behind, however,
perhaps on the grounds of cost;
although this is something of a false
economy.
The disparity between the two
documents is an important consideration
for specifiers and facilities managers.
It is still perfectly acceptable to follow
DW/144 to design, construct and
install ductwork. However, following
DW/144 to the letter means that, at its
first professional clean, the system will
almost certainly require additional access
hatches to be retrofitted in order to
achieve compliance with TR19.
This can be a huge headache and it
is far more cost effective to include
sufficient access points at the design
stage. Retrofitting them at a later date
may even be impossible if other features,
such as fixed ceilings, have been added
after the ductwork has been installed. A
far more sensible approach would be to
design every new ventilation system with
TR19 compliance in mind, ensuring there
are sufficient access points to clean the
entire system from the outset.
TR19 is currently undergoing revision,
and we expect it to be reissued shortly
as TR19 Air. This follows the issuing of
TR19 Grease, the sister specification
which governs the cleaning of kitchen
extract ductwork systems. We anticipate
that TR19 will actually increase the need
for access points, recommending that
they occur every two metres, at even
greater odds with the requirements of
the current version of DW/144.
Access to the entire system is also
critical on safety grounds, especially on
either side of a fire damper. Fire dampers
are located at the point at which
ventilation ductwork passes through an
internal fire-resistant wall creating an
opening in a fire-resistant compartment.
Fire dampers comprise a set of steel
louvres which remain open to allow air to
flow freely, and close automatically in the
event of a fire to form a barrier designed
to prevent smoke and flames from
passing through the fire-resistant wall;
resealing the compartment.
Ideally, we would like to see DW/144
be revised to bring it in line with the
expected TR19 Air, incorporating
sufficient access to the entire system to
allow future cleaning and compliance.
Until then, it seems only sensible to
design with future compliance in mind
and to follow the requirements for TR19
from the earliest stage.

COLOURED RADIATORS ADD
WARMTH TO STUDENT
ACCOMMODATION
The heating system in a block of student accommodation in Leeds was given a
splash of colour with the addition of 92 Stelrad radiators in anthracite grey.
University students these
days expect quality student
accommodation, and part of that
includes being able to stay in a warm
and comfortable room served by a
decent heating system.
Students at Leeds University are now
able to benefit from a heating system
that shares its heat through a selection
of Stelrad radiators – in anthracite grey –
a mixture of 92 Vita Deco Concept and
Compact with Style Coloured radiators.
There is a wide selection of potential
accommodations for students at the
University of Leeds to choose from,
including the impressive Devonshire Hall
in Headingley, just a short walk from the
world famous cricket and rugby league
grounds.
Devonshire Hall is a Victorian Gothic
building which has been refurbished and
added to with modern buildings in the
grounds, that provide in total 592 rooms
for students to choose from. Most rooms
have a junior double or double bed, and
some of the standard rooms have a
wash basin, with some en-suite rooms
available.
The foyer of the original building features
a traditional fireplace with comfy chairs,
where students can relax with their
friends after a meal. Devonshire has a
vibrant and active community that allows
students selecting this as their home to
get involved with a number of concerts
and theatre performances throughout
the year. They even have the opportunity
to experience formal events ranging
from Halloween balls to Burns Night
celebrations.
The beautiful grounds are home to
an imposing main hall, converted
Victorian mansion houses, and other
new, purpose-built accommodation.
The Hall is great for music and theatre
enthusiasts, with practice rooms
available as a rehearsal space. There are
also great sporting facilities at the site,
with a gym and a squash court.
Stelrad’s North East and Cumbria
Specification manager, Lewis Aird, says:
“We were delighted to be selected to
provide the radiators for this phase of
the heating system upgrade. We’ve
been involved in a number of student
accommodation upgrade projects in the
last year or so, but this is the first one
I’ve been involved in where coloured
radiators have been selected. Many of
our radiators are available from stock in
anthracite grey and these radiators really
look very smart in the surroundings of
student accommodation – in en-suite
rooms or in the communal kitchen and
bathroom areas.”
The radiators were supplied by merchant
James Hargreaves in Hunslet and
Radiators offer a sensible
solution to sharing heat
from either a traditional
boiler driven system, or
renewable heating

CONFUSION AND CHAOS IN UK’S
ENERGY DIRECTION
Rinnai’s Chris Goggin examines the current state of UK domestic energy policy as the
UK phases out fossil fuels for renewable alternatives.
UK energy policy is currently
convoluted and chaotic with
apparent scant insight into
the future pathway and direction
provided to customers and energy
industry professionals. At present, the
UK relies on fossil fuels for national
energy resources, with the future aim
of transitioning to significant carbon
reducing alternatives. These reductions
are targets, written into law.
Solar, wind, and greener gasses like
hydrogen or renewal DME are likely to
play significant roles in delivering power
to UK housing and building stock once
natural gas usage is nullified. For this to
happen, a concise strategy must deliver
infrastructure and installations capable
of transporting clean energy into UK
properties.
To begin with, UK decarbonisation
plans and commitments have been
diluted, preferring instead to expand
and increase North Sea oil and gas
production. The Times newspaper
recently published an article that quoted
the UK’s largest insurance provider,
Aviva, 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 and
rising global energy costs has led to a
lack of investment within large scale UK
renewable projects.
The Energy Transition Readiness Index
2023 is a measurement of a region’s
ability to transition towards NetZero.
A report is 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 enough evidence of either to entice
outside capital investment.
Specifiers of heating and hot water
products must absorb centralised
information to devise a strategy capable
of producing carbonising solutions.
Presently, the flow of governmental
information can be contradicting and
even bipartisan. For a UK national
energy transition to be successfully
implemented, the information and
agendas must be clear and consistent.
Without this required synchronicity all
those in the supply chain risk appearing
uninformed, especially in view of
constant misinformation from a variety
of questioning sources and bodies.
The industry needs a unified approach
which delivers clean, sustainable and
renewable energies with all associated
appliances and systems.
Hydrogen is an example of the confusion
that travels throughout the UK energy
For a UK national energy transition to be
successfully implemented, the information and
agendas must be clear and consistent
sector. Two recent reports have been
released claiming a contradicting
outcome regarding the future of the UK
national gas transmission network. The
Future of Great Britain’s Gas Networks
Report by the National Infrastructure
Commission and Ofgem, say that
the national gas network should be
decommissioned in favour of widespread
electrification.
An additional report, funded by UK gas
operator Cadent and conducted by
The Imperial College of London, has
stated that a switch to hydrogen as
domestic and commercial fuel could
save the British taxpayer up to £5 billion
a year when compared to widespread
electrification.
Offshore wind is a further area of the
energy industry that is encountering
problems. Despite government subsidies
being made available, major renewable
firms are beginning to question the
viability of huge UK offshore wind
projects.
Solar energy appears to be the least
turbulent and contested area of energy
adoption. Solar is well placed to play
a significant role in future UK power
provision. If wider electrification is
embraced solar will contribute by way
of delivering a source of generational
power.
However, due to the uncertain state of
UK energy policy, any move towards
solar will be in the future. The main
issue regarding present solar power is
a long wait for grid connectivity. Some
businesses and domestic customers
have been told that they must wait
between 10 and 15 years for access to
the UK grid. A lack of infrastructure and
a queuing system for grid applications
are contributing factors in this long wait.
Contractors, specifiers, system
designers and installers of home heating
and hot water systems should consider
companies such as Rinnai, which offers
a range of decarbonising products that
ensure low customer costs and efficient
performance.

ALPHA LAUNCHES THE ‘NXT’
GENERATION OF GAS BOILERS
HEATING AND
VENTILATION
Alpha has added the ProTec
NX to its portfolio of gas
boilers, offering a highefficiency,
fan-assisted
condensing boiler for
commercial applications, as well as
larger domestic projects. Offering
the maximum efficiency available for
condensing boilers, the ProTec NX
improves running costs and has ultralow
emissions to meet the latest building
regulation and authority requirements.
Available in six individual outputs ranging
from 48kW up to 180kW, the boiler
range has the capability of cascading
to achieve higher outputs and increase
load flexibility. Its wide 1:10 modulation
range enables the boiler to run at a low
output with fewer on/off cycles, reducing
emissions and increasing longevity.
The ProTec NX offers an easy-to-fit unit
which can be either wall-mounted or
fixed to a freestanding low or ultra-low
frame. The boiler is factory-fitted with a
room-sealed ‘C’ flue type configuration
but is also compatible with B23 or twin
flue systems using the stub kit.
The new range offers a more compact,
space-saving solution, especially when
banking boilers together with a range
of flue options for individual, cascaded
and different ventilation scenarios. A
wide range of hydraulic accessories
is available to link boilers, and plate
exchangers and low loss headers to feed
multiple heating and hot water zones.
The ProTec NX has an inbuilt option
within the boiler control panel capable
of setting programs, temperatures and
zones to suit the system need. Using
Alpha’s smart commercial controls,
it is possible to link multiple boilers in
cascade and drive them all from one
‘master’ boiler.
Alternatively, separate controls can be
used to manage the ProTec NX, either
through Alpha’s own cascade controller
or a separate panel from the plant
room. Input from these can be simple
ON/OFF control; or using OpenTherm
compatibility.
The commercial controls engineered
by Alpha are not only technologically
advanced but compatible with a broad
spectrum of market options, ensuring
seamless integration and maintenance.

FERNOX EXPANDS RENEWABLE RANGE WITH
NEW ANTIFREEZE VALVES
Fernox has introduced new TF1 Antifreeze Valves to its
portfolio of renewable products. Available in two sizes
suitable for both compression and BSP fittings, the highperformance
valves have been specifically engineered for
heat pumps, to prevent ice forming in heating and cooling
systems and damaging the heat pump itself.
When temperatures drop, systems that are not treated
with a glycol-based fluid can freeze within the heat pump
circuit, potentially resulting in costly damage to components
and pipework. The Fernox TF1 Antifreeze Valve reduces
this risk thanks to its internal sensor, which detects when
the fluid in the system is close to freezing. When the
circuit temperature drops to 3°C, the valve discharges a
small amount of fluid, allowing the circuit to drain until the
temperature rises.
Manufactured from brass for robust, durable and longterm
operation, the valve is available in two sizes – either
28mm Compression or 1¼” BSP.

FIRE AND SECURITY
MANAGE FIRE RISK WITH EFFECTIVE
COMPARTMENTATION
Compartmentation is a critical line of defence for fire safety, with accurate
specification essential to delivering life-saving performance in the event of a fire.
Here Joshua Slack, Promat’s National Specification Manager, explains how.
For fire safety policies to work
effectively and meet building safety
regulations it is critical that buildings
are designed and constructed to allow
time for occupants to evacuate safely,
and for the fire and rescue services to
tackle the blaze and protect the integrity
of the building. Compartmentation is
essential to this, providing fire protection
for walls, ceilings and steelwork to
contain the spread of heat and smoke.
Compartmentation involves dividing a
structure into ‘compartments’ that are
protected using fire-resistant materials.
For effective protection a holistic
approach is required. This means as well
as the walls and ceilings themselves,
any element that forms part of the
compartment line, such as doors,
firestopping or steelwork encasements,
must maintain the performance of the
element as a whole.
By creating compartments using fire
protection boards along walls and
ceilings, and to encase structural steel, a
fire can be contained within a determined
area for a set period, as long as the
correct level of passive fire protection
has been specified. This underpins the
effectiveness of any measures taken to
address a fire risk in a building, including
‘Stay Put’ policies and the creation of a
fire safety corridor to allow vital access to
the emergency services.
Specifying compartmentation
Fire-rated partitions play a crucial part in
ensuring the safety of all buildings, from
warehouses and commercial premises
up to high-rise office blocks. With such
a wide range of possible applications,
there can be a vast difference in the
scope of specification for passive fire
protection.
For compartmentation to provide the fire
protection required, it is essential that the
correct system is specified. Promat, for
example, manufactures fire protection
boards that can be built into fire-rated
systems to provide protection from the
spread of heat and smoke for between
30 and 240 minutes, with the correct
fire-resistance period being dependent
on the type of building, the height, size
and complexity of application. This must
be supported by the effective use of firestopping
systems to provide a protective
seal where penetrations have been made
into the board to accommodate, for
example, pipework.
A simple, straightforward structure will
see the use of fire protection boards on
ceilings and walls that have been tested
and certified in that application. A more
complex building may require a bespoke
approach, including the support of a
fire engineer to ensure compliance with
Approved Document B fire regulations
and the Building Safety Act.
To demonstrate it meets the required
standard, all passive fire protection
systems must have a valid testing report.
Promat advocates that boards and
products are certified by a recognised
third party, where possible, as well
as meeting the necessary EN fire test
standards.
In more complex projects, the sheer
variety of applications means there
may not be existing test standards
and certification systems to cover
that particular use. In this case, a fire
engineer will be needed to demonstrate
how the use of separately tested
systems can meet the project’s demands
– potentially requiring additional technical
support and testing.
Technical support
With the introduction of the Building
Safety Act there is a greater emphasis
on the need for early specification, so it
is important that compartmentation is
factored into any project at the design
stage. This will ensure any potential
issues are flagged, and the necessary
support sought to ensure correct
specification.
Adequate maintenance is also vital to
ensure the compartmentation continues
to perform as required throughout the
life of the building. This involves ensuring
any damage is promptly repaired and
any post-installation penetrations, such
as for new pipework, is firestopped
with products certified for the specific
application.

with building safety to create spaces that are not only
safe and functional, but also welcoming and inspiring for both
staff and students.
Designed by Wiersema Architecten and de Architecten CIE,
the Academy Tien is a beautiful new school building near
the centre of Utrecht. Catering for students between 10 and
18 years-old, the academy has been constructed with a
contemporary open plan layout, to maximise the building’s
natural light transmission.
JM Van Delft & zn, a specialist in glazing system solutions, was
contracted to deliver the fire-resistant steel interior partitions
and frames on the project.
Sales and Operations Manager Ruud van Dal said:
“Throughout this project, it was important that both aesthetics
and safety were considered and well balanced. There was a
clear requirement for keeping the school’s interior spaces light
and open, while simultaneously providing a safe environment
for students, staff and visitors to work and learn in. As a
result, fire safety glass was chosen as the perfect material for
installation within the building’s internal partitions, doors and
central atrium.
“Pyroguard Protect EW60 was installed within the doors,
sidelights and designated escape routes. Pyroguard Protect
EI60, which offering the highest level of protection, was
installed between classrooms and the central atrium, creating a
series of fire-safe compartments.”
This compartmentation process can form a key part of any
building’s passive fire protection strategy, working to split the
building up into a series of fire-safe zones. As well as helping
to limit the spread of a fire, this can also provide both a safe
route of escape for occupants and a means of entry for the
emergency services.
Ruud continued: “Pyroguard Protect’s high visual appearance
helped to maintain the light and open interior that the architect
desired, while its multi-functional capabilities proved key in
delivering improved acoustic control and impact resistance –
something which was a clear priority when designing the new
academy.”
Pyroguard Protect is a toughened fire safety glass, certified for
use in steel, timber and aluminium profiles. Providing 30 to 180
minutes of protection against smoke and flames, 1B1 impact
resistance, and UV stability, Pyroguard Protect ensures that
both design and safety requirements can be achieved.
The Academy Tien opened its doors to students in January
2024.

PRODUCTS
Insulation manufacturer Marmox has introduced a highly
versatile Fireboard into its range for both internal and
external wall insulation (IWI/EWI) applications.
The Marmox Stone Wool-based product shares the
Marmox honeycomb surface structure with its XPS
forerunner, Multiboard, to create a weatherproof, A1 noncombustible
certified render-backer. It can further be used
internally across walls or ceilings to take a plaster finish,
while providing sound absorption properties, as well as
thermal insulation. The 600 x 1,200mm Fireboards are
available in thicknesses from 20mm, 50mm and 100mm
and with the polymer-modified mortar honeycomb coating
applied to both faces. With a nominal density of 150kg/m 3 ,
the boards’ core material offers a compressive strength
of 90tonnes/m 2 . The 20mm Fibreboard is also suitable for
external window and door reveals, ready for rendering.
Grant Terry, Marketing Manager for Marmox, said:
“The introduction of Fireboard into our range significantly
enhances our offer to the construction industry, meaning we
have an A1 non-combustible backer board for internal or
external use, which can safely be installed across masonry
as well as timber or steel framing systems. The Stone Wool
boards are made of formed molten rock, meaning it is
impossible for the fibres to absorb moisture, so they will not
degrade no matter what weather they are exposed to.
“The thermal conductivity of 0.037W/mK delivers very
good thermal insulation, while the tiny air pockets within
the micro-fibre structure of the Stone Wool serves to
interrupt the pathway for sound transmission, which solid
materials facilitate. We expect Fireboard to find applications
in newbuild and refurbishment work within residential,
commercial and other sectors.”
Marmox Fireboard has been tested to prove compliance
with BS EN 1182, EN 1716 and EN13823 (Resistance to
fire test) conducted by UKTC, along with other testing
completed by the BRE.

CPD PROMOTES FIRE SAFETY OF
MULTIFUNCTIONAL ROOFS
ROCKWOOL has launched a new Continuing Professional
Development (CPD) module to help specifiers and roofing
contractors assess and mitigate potential fire safety risks
for flat roofs used as additional functional space of a
building.
Flat roofs are a common construction, especially in
busy urban environments where space is at a premium.
Leveraging flat roof space enables designers, developers
and ultimately tenants to make use of the ‘fifth façade’ for a
variety of social and practical purposes.
The CPD aims to improve understanding of the role of the
modern flat roof, and how to identify and mitigate fire risks
above and below the roof.
Participants will learn about the requirements of
the Building Regulations for flat roofs and the role of
guidance documents like Approved Document B, or
regional equivalents. The final section of the CPD outlines
ROCKWOOL’s range of fire-resistant stone wool insulation
products.
The module is available through the bespoke
ROCKWOOL Learning platform, or as a traditional in-person
course.
Lisa Stephens, Product Manager – Building Envelope,
ROCKWOOL UK said: “By taking part in this CPD module,
roofing professionals will learn about the implications of
practical and social installations on flat roofs, and their
impact on design and build. The CPD also addresses the
situation surrounding solar PV installations and how this is
reflected in regulations and guidance.”

FIRE AND SECURITY
FIRE SAFETY FOR THE HEALTH
SECTOR
Peter Barker, Technical Manager at Warringtonfire, discusses the important role of
fire doors and the key considerations to ensure they will perform as required in the
event of a fire.
From hospitals to nursing homes,
given their size and complexity,
healthcare premises present
major challenges when it comes to fire
protection in buildings. As such, having
a clear and robust fire safety strategy is
crucial.
Given that complete evacuation of a
healthcare site is often impractical and
highly challenging, the most common
approach is progressive horizontal
evacuation. This involves moving
occupants from the fire-affected area,
through a fire-resisting compartment line
to an adjoining area, which is designed
to protect the occupants from fire and
smoke. If safe to do so, the occupants
then remain in the fire safe area (refuge)
until the fire is extinguished or, if
necessary, further evacuation is required.
In conjunction with other measures,
fire-resistant compartment lines are a
critical element of a fire safety strategy.
If the fire-resistant compartment lines
and fire doors cannot be relied upon, the
evacuation strategy for the hospital will
be severely compromised.
Healthcare fire doors
A fire doorset specified for use in a
hospital or healthcare facility will have
to provide fire resistance to meet the
functional requirements of Part B of the
Building Regulations. According to HTM
05-02: Guidance in support of functional
provisions for healthcare premises,
unless pressurisation techniques
complying with BS EN 12101-6 are
used or the door is in a cavity barrier, the
doorset must also offer smoke control.
However, there are many other
performance and design requirements
that healthcare fire doors must adhere
to. Cross-corridor doorsets will need to
withstand constant opening and closing,
as well as resisting potential damage
caused by regular impacts from hospital
trolleys and wheelchairs. Doorsets into
cleanrooms must be totally hygienic to
avoid harbouring harmful pathogens,
while doors on high-security wards must
safeguard patients and staff.
Planned preventative maintenance
Ongoing maintenance of fire-resisting
doorsets should be incorporated in a
programme of inspection. This is key to
the longevity of fire protection elements
and anticipating malfunction or defects
before they occur. Planned Preventative
Maintenance (PPM) is often the typical
approach, involving regular inspections
dictated by relevant risk assessment,
professional judgement and local
circumstances.
Given that damage is largely caused
by staff while transporting patients and
goods, encouraging staff to use doors
in a caring, responsible manner can
mitigate the chances of this happening.
This is especially important for personnel
who use equipment and machinery that
have a high risk of breaking the door,
such as pump trucks, trolleys and beds.
If the doorset is in an area with
particularly high traffic, it may be
necessary to include design features,
such as electronic hold open devices,
that automatically release the doors on
activation of a fire or smoke alarm. Such
devices must be approved for use with
the doorset designs on site and regularly
checked.
Resolving issues
If a fire-resisting door requires
remedial works, it is crucial that this
incorporates operational functionality
and fire performance. For this reason,
the person undertaking the works
must have a sound knowledge of
fire-resisting doorsets, and familiarity
with the appropriate testing and
certification process. They also need to
be competent in their skills, experience,
and behaviours to ensure the doorset’s
performance is maintained. All too
often, well-intended repair works by
improperly trained personnel can have a
detrimental impact on the fire-resistance
performance of the door; whether by
replacing glazed elements without the
correct fire-rated glazing seals or fitting
incompatible hardware.
While not currently mandated in the
UK, NHS bodies are encouraged to use
third-party certification schemes in HTM
05-02: Guidance in support of functional
provisions for healthcare premises. BM
TRADA provides a number of such
schemes for fire door manufacture,
installation and maintenance to help
provide confidence in the performance
of a doorset throughout its operational
lifetime.

FIRE AND SECURITY
IS SECURE PRIVACY GLASS A DOOR
TO THE FUTURE?
Susan Sinden, Commercial Manager of ESG Group, explores a new use of LCD glass
technology, combining security with the ability to switch between visibility and
privacy for doors and entrances.
At one time, privacy glass
was synonymous with
frosted or etched opaque
glass. While this certainly
delivered privacy, it was an
all or nothing approach, and restoring
transparency meant replacing the glass
with a clear pane. With advances in
glass processing and the advent of
switchable LCD interlayers, privacy
has become a more versatile concept.
Specifiers no longer need to choose
either transparency or privacy; the LCD
interlayer delivers both.
Switchable privacy glass products
act exactly as the name suggests;
transparency and privacy can be
switched on and off at will. A small LCD
current is passed through the interlayer
when switched on, causing the liquid
crystals within the interlayer to align
and the pane to become optically clear,
allowing the end user to see through the
glass. As soon as the electrical current
is switched off, the liquid crystals settle
into random configurations and the glass
becomes opaque, completely restoring
privacy. As the glass is opaque until
the current is passed through it, it has
become a popular choice for en-suite
bathrooms and mezzanine walls, as well
as partitions in open plan living and work
spaces.
Switchable glass is also growing in
popularity as a door panel, replacing
spy holes and completely removing the
need for security chains. Interlayers can
be used to provide a range of different
characteristics in glass, including high
security and resistance to intruders, or
sound attenuation. Critically, more than
one interlayer can be used in a single
glass product to produce glass products
with multiple properties. Therefore,
privacy and security can be combined
to create a door with a large but secure
glass panel. By replacing an entire door
panel with a glass product such as ESG
Secure Vue door panels, the occupant
is able to switch the panel on to see any
caller in far more clarity than through a
spy hole and without opening the door
or neighbouring window.
To view the caller, the occupant simply
switches on the panel, either with the
press of a button or using an app or icon
on a smart phone or tablet. This simple
push button or icon tap operation is
also easier to use for those with limited
dexterity. The caller can then be clearly
viewed through the transparent glass
without sacrificing any security.
Once the caller has been admitted or
has left, the glass panel is switched off
to restore complete privacy. There is no
need for mains wiring as the amount of
electricity needed to operate the LCD
door panel is minimal. Instead, a small
battery pack is installed in the door
frame to power the Secure Vue glass
panel, and the battery will not need
replacing for some considerable time.
The advantages of being able to view
the caller without opening the door are
obvious, especially in settings involving
the elderly or infirm. There are also
other benefits, such as not opening the
door in winter and allowing valuable
domestic heat to escape. Secure privacy
door panels would also be suitable in
sheltered housing accommodation,
where a warden could use an app to
observe first hand that residents are well
and safe without having to enter.
Secure switchable door panels have
an obvious application for domestic
front doors, but also for a wide range of
commercial and public sector settings. In
hospitals, for example, switchable door
panels have practical applications for
monitoring patients visually, or for holding
consultations in privacy. Door panels
have been installed in operating theatres,
laboratories and clinics to provide the
versatility of privacy or openness as
required.
These panels are also suitable for
secure high value retail or banking
settings, and even detention setting
applications, allowing occupants to
security check visitors before admitting
them. In custodial settings, switchable
glass panels provide a far larger and
clearer view of detainees who need to be
monitored than with limited observation
hatches.

FIRE AND SECURITY
MAKE THE IMPOSSIBLE POSSIBLE
When it comes to creating buildings which include architectural elements, intricate forms or
accent details, complex brickwork detailing can be achieved using specialised products to
make the exceptional attainable. This is where special lintels come into their own for
architects and designers. Keystone Lintels explains why.
Steel lintels are not specified simply
for their loading conditions, length
or type of wall under construction,
and have moved on considerably from
their timber or stone predecessors.
Contrary to a common misconception,
special lintels are not limited to basic
loading solutions. In fact, with larger
spanning special lintels, manufacturers’
technical engineers can incorporate
structural steelwork into the design. The
shop floor then rolls, mitres, welds, and
bolts the beams as necessary to form
the desired structural shape.
Special lintels are bespoke, made-toorder
products that are designed to be
fit for a specific purpose. Each lintel is
designed specially to suit the load or
aesthetic requirements for any given
opening on a build.
The range of special lintel solutions
offered by Keystone Lintels, for example,
can cater to different architectural
visions. For example, corner lintels can
enhance spaciousness and natural
light in a room while splayed bay and
square bay lintels can achieve a timeless
blend of classic and contemporary
elegance. From large apex lintels
that are perfect for accommodating
impressive glazed openings to full and
segmental arch lintels, gothic, parabolic,
and venetian arch lintels that provide
striking architectural features, there are a
range of solutions for designers seeking
creative freedom.
St Clement’s Heights
At St Clement’s Heights – a mixed
private housing and supported living
development in Sydenham Hill,
London – Saunders Architects required
three heavy-duty special lintels to
accommodate the scale of the secondfloor
openings.
The four large glazed apex openings
provide a source of natural light to the
second-floor master bedrooms, helping
to create a bright and comfortable
living space. The 4m openings
accommodated glazed sliding doors
leading out onto the balcony.
Keystone engineers designed a solution
that accommodated the 2m high apex
detail, while considering the location of
the ridge beam to avoid any clash and
need for fixing.
The end bearings of the lintel were
increased to 225mm to help better
distribute the loading applied.
Additionally, the design incorporated a
spreader plate at the apex on the inner
leaf to further ensure the structural
integrity of the lintel once built-in, taking
into account the position of the steel
ridge beam overhead.
“We’re always looking to provide
innovative solutions for any type of
challenge presented to us; big or small,”
said Ciaran McAliskey, Specification
Manager at Keystone Lintels.
Each lintel is designed
specially to suit the
load or aesthetic
requirements for any
given opening on a
build
Sun lounge systems
The potential for special lintels and
systems to significantly enhance a
building project is further exemplified by
Keystone’s Sun Lounge Lintels. Offering
greater practicality and user friendliness
than a conservatory, a Sun Lounge Lintel
is an easy way to add space and value
at minimal cost when building a new
house or extending an existing property.
A Sun Lounge Lintel is more visually
appealing than a conservatory and offers
much better heat retention in winter, and
protection from the blazing summer sun.
Moreover, incorporating a Sun Lounge
floor area into the overall measurement
of the house size can add considerable
value to the property. It goes through the
same approval and delivery process as
Keystone’s other special lintels, and is
manufactured similarly to bay lintels. In
cases where the Sun Lounge Lintel is too
large to be maneuvered or transported
in one piece, it can be supplied in two
or three manageable sections that
seamlessly bolt together on-site.
Personalised service
Keystone Lintels not only offers a special
range of lintels but also provides a host
of complementary services that include
free scheduling and specification,
customised design, and on-hand
technical expertise.

A MASTERPIECE FOR MASTERTRACK
York-based glass merchant and glazing contractor, Kimberlite Glass, has been a
Bohle customer for over 20 years, and their latest project showcases the strong
partnership they have with the hardware company to fulfil their innovative designs.
CASE STUDY
Kimberlite Glass is a staple
of the York glass industry:
based in the same premises
since 1976, the company
has developed a strong
reputation for high quality installations,
supplying and fitting a huge range of
glass including splashbacks, shower
screens, mirrors, and double-glazing.
With contractual projects for both
schools and universities, as well as
its own design and installation team,
Kimberlite Glass is renowned for its
ambitious results.
The company’s latest project is no
different – a floor-to-ceiling opaque
glass box with a sliding glass door
constructed to house an en-suite within
the bedroom of a residential property.
“We were approached by the company
that was contracted to manage the
project,” says Kimberlite Glass Owner
and Director, Ed Appleton. “It was
The glass was so heavy
that we needed to
reinforce the ceiling to
support the weight, but
with the MasterTrack
system the doors
opened effortlessly
a really impressive project that they
proposed: an unused corner of a
bedroom would become a top-spec ensuite,
framed within a glass box.
“We did the calculations for the glass
– considering the type and thickness
of the glass, we worked out that each
glass panel would weigh nearly 100kg.
We knew with that kind of weight that
we would need the highest quality
hardware to support it, so we went
straight to Bohle.
“When I spoke to Helen at Bohle and
told her what we needed to achieve,
she immediately recommended the
MasterTrack system,” Ed explains.
MasterTrack is Bohle’s internal
sliding door system. Designed to
accommodate glass thicknesses
between 8mm and 12.76mm, and with
maximum weights of 150kg, it can be
either be wall-mounted or ceiling hung.
Capable of being installed in as little as
10 minutes thanks to an easy-to-use
clamp system, it is particularly suitable
for the home improvement and light
commercial sectors.
MasterTrack also uses a patented
hydraulics system and a double-sided
spring to slow the door in a single, ultrasmooth
operation.
“The glass was so heavy that we
needed to reinforce the ceiling to
support the weight, but with the
MasterTrack system the doors opened
effortlessly – you’d never know that you
were sliding nearly 100kg of weight!”
Ed says. “It was simply the best system
for the job. It enhanced the style of
the project, it had the correct weightbearing
credentials, and it is a high-end,
quality product. We know once we’ve
installed a MasterTrack system, or any
Bohle hardware for that matter, that
we won’t be getting callbacks for faulty
door closures: this is obviously vital to
us as we don’t want to be spending
time and money back on site replacing
sub-standard parts.”
For Kimberlite Glass, the company’s
relationship with Bohle shows no signs
of slowing. Ed continues: “I’ve been the
Director of Kimberlite Glass for 20 years,
and in that time, we’ve always used
Bohle products. I know my predecessor
before me also used their hardware too.
“For us, it’s all about quality. We have a
reputation to uphold, and we know that
by using Bohle, we won’t get caught
out on quality. You can’t go wrong with
German engineering.
“And they offer everything glass-related
you could possibly need, for hundreds
of different projects. We know that
whatever the challenge, we can go to
Bohle and they will be able to offer us
an honest solution.
“The staff are so friendly and helpful,
and they actually care that they’re giving
us the correct products for the job – it’s
not just a tick box exercise for them.”

THE RESIDENCE COLLECTION UPDATES BESPOKE
CONSERVATION AREA DEVELOPMENT
Premium window and door designer The Residence
Collection has completed a newbuild development in the
conservation area of Woolley, near Wakefield. The highend
luxury development, named Old Beech Farm, features
more than 200 Residence Collection windows across six
newbuild properties.
Alongside fabricator HWL Windows and an independent
housebuilder, the traditional R9 windows were added in the
Painswick colourway, to complement the stone exterior of
the homes. This project has also recently won Commercial
Project of the Year award at the G23 Awards.
The original timber alternative window, Residence 9, is
widely accepted in Conservation Areas and for Grade IIlisted
buildings across the UK due to the collection adhering
to the key principles, shapes and dimensions from the
Article 4 Conservation Area guidelines for windows. This
particular window system was chosen by the developer due
to its low maintenance and superior performance features,
as well as the high-end finish that fits the style of the
premium development.
The selection of windows, which meet Part L
requirements with a u-value of 1.2W/m 2 k, surpassing British
Building Regulation requirements, was based on their
thermal efficiency, heritage, and attractiveness to end-users.
The windows also achieve a certified A++ window energy
rating and satisfy Passive House standards, with u-values of
0.74W/m 2 k with 44mm triple glazing.
The Timberweld jointing technique was employed in the
fabrication of the Residence 9 windows. This welded joining
method creates a seamless butt-joint appearance on both
the exterior and interior of the windows, offering an authentic
timber look and enhanced strength.
The Residence Collection windows can be delivered
without glazing, facilitating easier on-site handling. For Old
Beech Farm, the windows were supplied with pre-fitted
Georgian bars.
Jo Trotman, Marketing Manager at The Residence
Collection, said: “At The Residence Collection, we prioritise
offering a selection of new windows that not only enhance
the aesthetics of properties but also deliver long-lasting
performance. This particular project opted for a colour that
perfectly complemented the exterior of the building, while
still capitalising on all the other performance qualities that
the R9 boasts.
“Establishing quality partnerships is crucial in the delivery
of our superior design, manufacturing, and installation
services that we consistently provide to our customers. We
are delighted to have successfully concluded yet another
project with HWL windows and look forward to many more in
the future.”

DURAPOST FENCING SYSTEM PROVIDES
LONG-TERM ALTERNATIVE TO TIMBER
A failing timber fencing system at a property in Leeds
has been replaced with a range of high performance
DuraPost products. Incorporating fence posts, Urban
Slatted Composite fence panels and an aluminium gate,
the solution from Birkdale Sales provided all the necessary
aesthetic and performance requirements.
While timber fencing can look attractive initially, it
inevitably begins to rot, weaken and deteriorate over time.
This was the case at the property of Mr Edwards, whose
ageing timber fencing was losing its appeal and beginning
to fail – so a replacement was needed.
“We wanted something that would look neater and not
require much maintenance. DuraPost by Birkdale seemed
to tick all the boxes,” said Mr Edwards. “The slim and
tidy galvanised steel posts in anthracite grey give me
more space in my garden and come with up to a 25-year
guarantee – although it is likely they will last much longer. I
then opted for the DuraPost Urban Slatted Composite fence
panels in the Natural colour option. It looks just like cedar,
but has greater longevity, thanks to its ability to resist mould
and rot.”
Birkdale’s Urban Slatted Composite fence panels are
manufactured from a combination of materials, including
rice husks – a natural bi-product from the rice industry –
which accounts for 55% of the panel. Recycled high-density
polyethylene (HDPE) is also incorporated into the design.
These robust panels are incredibly strong and wind tested
to high speeds.
