The UK government’s pledge to build 1.5 million

homes by 2029 is commendable, but actually

achieving this target seems highly unlikely given

the challenges our industry faces. Reaching the

target means building 300,000 homes every year

for the next fi ve years – three times the 104,232 new homes

registered to be built in 2024. In fact, it has been decades

since we achieved anywhere near that fi gure.

The challenges to building new homes en masse are

many and varied, from the over-reliance on private sector

developers, the lack of an established, national social

housebuilding plan, and an overly complex planning

system. Though planning reforms are underway, delays are

likely to continue while they are being implemented. The

availability of land presents another hurdle, especially while

balancing the need for new houses and the preservation of

green belt land.

Rising construction costs, the ongoing skills shortage

and continuing high infl ation and mortgage rates are

also deterring builders, though there are signs that the

construction industry is starting to return to slow growth.

While the 1.5 million target is a commendable idea that

will, hopefully, act as a catalyst for industry wide change,

achieving it is another matter entirely. Only through an

integrated, holistic approach to building and planning

reforms can the UK hope to overcome all these barriers.

Reynaers goes the

extra mile for charity

The Reynaers Aluminium UK team

has raised more than £3,000 for

Birmingham Mind charity after

clocking up 2,000km in a collective

step challenge.

The team challenged themselves

to walk the equivalent distance

from Lands Ends to John o’ Groats,

heading out on organised walks,

submitting their weekly step counts

and sharing photos of themselves

completing the challenge.

Far surpassing the collective

goal of 970km, the team achieved

2,003km – the equivalent of walking

from Lands’ End to John o’ Groats,

then from Reynaers’ Birmingham

headquarters to its global head

offi ce in Belgium, and halfway back.

As a result of the challenge and

subsequent donations, Reynaers

has donated £3,050 to Birmingham

Mind, which provides advice,

information and support for people

affected by mental health issues.

Birmingham Mind also supported

Pam Herbert in qualifying as

Reynaers’ fi rst Mental Health First

Strong start for private housing

Private housebuilding is shaping up to

be one of the most promising sectors

for new construction work in 2025 after

a strong start to the new year, according

to the latest Glenigan Index.

In the three months to the end of

January, private housing project starts

rose by 31% on the previous quarter

and were up 26% on the same period

a year earlier. This is in keeping with

predictions in the Glenigan Construction

Forecast 2025-2026 of a 13% rise in

the value of underlying private housing

starts (under £100 million) this year.

Housing market professionals are

also increasingly confi dent that better

times lie ahead. The January RICS

UK residential property market survey

showed a net balance of +10% of

agents responding were positive on the

outlook for house sales three months

ahead, with 30% positive on prospects

for the coming year.

Meanwhile, the volume of all house

sales agreed in January was 15%

higher in January than its recent trend

and demand was 8% higher, according

to Rightmove, the property search site.

The brighter outlook for the sector

is also refl ected in messages from the

larger quoted housebuilders. Barratt

Redrow has reported its private homes

order book rose by 11.2% on the period

a year earlier.

Passivhaus ‘accounts for 1% of new homes’

Projects being built to the Passivhaus

standard now account for around 1% of

all new homes under construction, the

Passivhaus Trust has said.

Passivhaus Trust data estimates there

are 2,250+ certifi ed Passivhaus homes

in the UK and more than 8,000 homes

targeting Passivhaus currently in the

pipeline. This represents 1% of all new

UK housing, assuming 2,000 projects in

the pipeline will be built per year.

Policy and funding changes, as well

as the standard’s growing popularity as

a solution to the energy bill crisis, are

all being credited with this increased

uptake within the UK construction

industry.

The Passivhaus Trust is now setting

itself the ambitious target of getting to

10% of all new UK homes by 2035,

which would require a tenfold expansion

within 10 years.

We’ve got just the ace up

English sites apply for new town housebuilding programme

More than 100 sites across England

have come forward to be considered

for the next generation of new towns as

part of the government’s housebuilding

programme.

Over 100 proposals have been

submitted from across every region in

England, which the government says

shows local areas and housebuilders’

ambition to build the next generation of

new towns – playing their part in getting

Britain building and tackling “the worst

housing crisis in living memory”.

Speaking during a visit to a housing

development in Buckinghamshire,

Prime Minister Keir Starmer said: “We’re

urgently using all levers available to

build the homes we need so more

families can get on the housing ladder.

We’re sweeping aside the blockers to

get houses built, no longer accepting

no as the default answer, and paving

the way for the next generation of new

towns.”

Housebuilders and local councils

have also highlighted more than 350

housing development sites currently

in the planning system that, they say,

could together unlock around 700,000

new homes.

Around a quarter of sites submitted

are reportedly already receiving

government attention since the call for

evidence closed in October.

Glidevale Protect and Superglass join forces

Glidevale Protect has announced a

collaboration with Superglass Insulation

to provide a collective system solution

for housebuilders, specifi ers and off site

manufacturers.

Achieving the required levels of

thermal performance, airtightness and

moisture control within the building

envelope is critical. The new working

partnership brings together both

companies’ respective expertise,

off ering insulating products for the

building fabric and tried and tested

solutions that achieve high energy

effi ciency and compliance when used

together as a full system.

A brochure exploring how Glidevale

Protect’s external and internal refl ective

wall membranes and Superglass

Insulation’s glass mineral wool insulation

can be used together to achieve low

U-values is available to download from

both company’s websites.

John Mellor, Head of Marketing at

Glidevale Protect, said: “For a home

to be energy effi cient and meet the

required regulations it’s important

for the individual materials specifi ed

as part of the building envelope to

complement each other as a system

and enhance the overall thermal

performance. Working collaboratively

with manufacturers like Superglass

Insulation is key to helping to reduce

the performance gap and ensure new

homes perform to the levels they have

been designed.”

Report calls for urgent action on fuel

poverty and poor living standards

There is an urgent need to improve

energy effi ciency in the private rental

sector (PRS), according to a new

report from the National Retrofi t Hub,

developed in partnership with Impact on

Urban Health.

With 4.5 million households renting

privately in England and a shocking

one in four renters living in fuel poverty,

according to Generation Rent, the

report delivers a clear message: without

immediate action, the PRS risks falling

further behind other housing sectors,

leaving millions of renters in cold,

ineffi cient homes.

The report proposes a supported

pathway to improved housing that

considers the needs of both landlords

and tenants.

It also calls for immediate updates to

Minimum Energy Effi ciency Standards

(MEES), setting ambitious yet achievable

targets to drive signifi cant, high-quality

retrofi t activity and minimise exemptions,

ensuring as many properties as possible

benefi t from improvements.

The report says landlords need a

robust package of support to enable

meaningful change, including tax

incentives to ease the fi nancial burden of

upgrades, and full-service solutions that

integrate fi nancing with retrofi t works.

To ensure tenants are not left behind,

the report also highlights the need for

stronger compliance and enforcement

measures, including robust tenant

protections during retrofi t works, and

increased funding for local authorities to

enforce regulations effectively.

Cara Holmes, National Retrofi t Hub

Technical Programme Manager, said:

“The private rental sector risks falling

behind other housing tenures, leaving

renters trapped in a cycle of inadequate

housing and energy insecurity. Tackling

this problem requires a coordinated

eff ort to raise standards, improve living

conditions, and ensure fair outcomes for

both tenants and landlords.”

Rayner pledges £350m

for affordable homes

An extra £350 million has been

pledged by the government for social

house building programmes to ‘get

Britain building’.

Deputy Prime Minister Angela

Rayner made the announcement,

which will see £300 million added to

the Affordable Homes Programme

and £50 million for the Local

Authority Housing Fund.

This, the government said, will

enable 2,800 more homes to be

built, with half available for social

rent, as well as providing better

quality temporary accommodation.

Rayner said: “We’re driving

forward on our plans to ensure

a better future for everyone who

needs a safe home...drivie up

living standards and build 1.5

million homes through our Plan for

Change.”

Coordinated action ‘urgently needed’

to remediate unsafe buildings

A centrally coordinated programme is

urgently needed to address barriers

to remediating unsafe buildings, the

National Fire Chiefs Council says.

In Remediation, a new industry

white paper, NFCC has said that,

despite progress being made, there

are longstanding challenges yet to be

addressed. The paper sets out some of

the barriers to meeting the Government’s

targets – including signifi cant diffi culties

in identifying and inspecting affected

buildings and tackling workforce

shortages.

Fire Chiefs are also calling on the

government to step up efforts to manage

the risk for those currently living in

aff ected buildings, by increasing the

use of sprinklers in existing residential

buildings over 11 metres, based on risk

assessment.

The white paper was published in

the same week as the government’s

response to the Grenfell Tower Inquiry

Panel’s fi nal report. The government said

it accepted “all the Inquiry’s fi ndings and

the problems that it highlighted need to

be fi xed. We are committed to taking

forward the work required to address the

Inquiry’s recommendations, and indeed

to going further: we must embrace not

only the specifi c fi ndings, but their spirit.”

Window retrofits ‘key’ to upgrading social housing stock

With local authorities and housing

associations facing acute pressure to

upgrade millions of social homes in

line with modern net zero and thermal

performance standards, retrofi tting

energy-effi cient windows and doors will

off er a vital way forward.

This is the view of REHAU’s Retrofi t

Right – Making Social Housing More

Energy-Effi cient report, which explores

how 4.4 million UK social homes across

the UK – mostly built between 1945 and

1980 – can be decarbonised in line with

legislative requirements and available

funding.

The whitepaper underlines the

importance of window and door

systems in aff ecting heat loss in

residential properties, detailing relevant

standards, regulations and metrics

such as those governing thermal

performance, noise attenuation, security

and ventilation. It can be downloaded at

COVER FEATURE

ARBOSHIELD PRO DELIVERS

FUTUREPROOFED PERFORMANCE

Mark Halliday, Divisional Façade and Technical Manager at ARBO, part of CARLISLE

Construction Materials, discusses how the ARBOSHIELD Pro range helps specifiers

deliver their new Building Safety Act obligations.

but also in the future as product

development and regulations evolve.

Among the products within the

ARBOShield Pro system is the

ARBOSHIELD Pro External Perimeter

Class A Membrane (EPAM), which

ensures a neat, fi re safe, compliant, and

trusted installation on all window, door

and façade structural openings.

It may be 18 months since changes

to the Building Safety Act (BSA) came

into force, but confusion still remains

about the implications for specifi ers and

contractors, and the obligations for every

link in the delivery chain.

At CARLISLE we are supporting

specifi ers by working collaboratively

with customers across our CARLISLE

waterproofi ng and ARBO façades and

sealants ranges to provide technical

advice and clear and verifi able

performance data. This helps deliver

a more collaborative and accountable

delivery chain, which forms a central

part of the updated BSA’s. We have

also published a handy guide to the

legislation, specifi cally in relation to fi reresistant

façades.

Changing obligations

A notable change to the BSA is the

introduction of mandatory Duty Holders

for every project – usually assigned to

the Principal Designer and/or Principal

Contractor – making them responsible

for building safety. The Duty Holder may

be penalised for non-compliance, so due

diligence in verifying the performance

capabilities of each specifi ed product

is essential, requiring an understanding

of testing and certifi cation, compatibility

with other building materials used, and

application suitability.

The legislation requires clear, verifi able

project data; a ‘Golden Thread of

Information’. This gives the project

an audit trail from conception to

completion, designed to ensure that the

completed building can be eff ectively

managed throughout its lifespan.

This requirement for accurate, relevant,

and accessible information at all stages

is intended to drive best practice

specifi cation and project delivery,

elevate safety and performance

standards in our built environment, and

futureproof buildings by compelling

those responsible to make informed

and justifi able decisions when selecting

materials. The goal is that specifi ers

will do more than achieve the minimum

standards required for compliance,

because they are accountable for the

legacy of their choices in terms of

performance and safety.

Improving fire safety

While much of the industry scrutiny

regarding façade safety has been

focused on cladding, the BSA requires

that the complete façade build-up is

subject to the same robust and informed

decision making to underpin safety. The

ARBOSHIELD Pro façade system from

CARLISLE has been developed and

tested as a cohesive, high-performing

system, comprising an extensive group

of products delivering Class A or B

reaction to fi re and W1 resistance to

water penetration. Tested as a complete

system, it provides total peace of mind

for both end user and specifi er that the

building will be compliant with safety

legislation, not only on completion,

Creating a watertight and airtight

seal with certifi ed fi re resistance, the

ARBOSHIELD Pro EPAM connects a

concrete structural frame or steel frame

to SFS sections and exceeds the current

Building Regulation and Approved

Document B requirements for a fi re

and weathertight seal, futureproofi ng

the project. With a self-adhesive

backing that bonds in temperatures as

low as -40°C, it can also be used for

applications such as weather sealing

of parapet walls, and weatherproofi ng

balcony details.

Prioritising performance

While safety is always a priority,

specifi ers also have an obligation to

select façade systems that will maximise

performance as part of a robust building

envelope specifi cation. Selecting

rigorously tested and compliant systems

that combine performance with ease of

installation is essential.

By simplifying the façade installation to

improve buildability, the ARBOSHIELD

Pro reduces the risk of errors, and the

products work in combination to deliver

airtight and waterproof details around

windows and structural openings. In

this way, the ARBOSHIELD Pro system

contributes to long-term building

performance and a more thermally

effi cient building.

CASE STUDY

VENTILATION GOES TO THE

TOP OF THE CLASS

Passivent has supplied a combination of Hybrid Plus2 Aircool ventilators and

Hybrid Plus Airstract roof ventilation terminals for a new London primary

school to help create a healthier, more comfortable learning environment for

children and staff to thrive in.

Greatfields Primary School in

Barking and Dagenham is a

three-form entry school which

will eventually serve 630 pupils. This

£11.8m building project was overseen

by main contractor Auburn Group, who

worked alongside Net Zero Buildings,

the offsite construction partner. By

building the structure offsite, disruption

was minimised in the local area during

construction, helping to meet the

project’s overall sustainability targets.

Working with Cedar Mechanical and

Electrical, Passivent supplied 58 Hybrid

Plus2 Aircool wall ventilators, each

mounted behind an external weather

louvre, to ventilate the classrooms

with fresh air from outside. The team

also supplied several of its Hybrid Plus

Airstract roof terminals for ventilation

of the school’s main hall. Passivent

provided temperature and CO 2

sensors

in each space, along with a 35-zone

iC8000 controller to regulate the internal

environment. The whole system was

linked back to the Building Management

System (BMS).

Passivent’s Hybrid Plus2 Aircool and

Hybrid Plus Airstract units both operate

on three modes of use for ventilation

provision or extraction, depending on the

needs of the building and the external

conditions. By drawing on both natural

and mechanical ventilation techniques,

the system is designed to be more

energy efficient and therefore more cost

effective. The Hybrid Plus2 Aircool units

are suitable for use in classrooms and

can be mounted in a wall or window, and

are also available as a ducted version for

installation in a ceiling void. The roofmounted

Hybrid Plus Airstract terminals

come with a 15-year no leak guarantee

and are particularly suited for large open

spaces such as school halls and sports

halls.

Marcus Bloomberg, Electrical Operation

Manager at Cedar Mechanical and

Electrical, says: “We were extremely

impressed with the results of

incorporating Passivent’s natural

ventilation solutions into this project. Not

only does the system deliver excellent

airflow and create a comfortable

environment, but the unique design of

the units also stands out. The softer,

curved shape adds a touch of elegance

and blends beautifully with the overall

aesthetic, providing a refreshing

alternative to the typical rectangular

units.”

Marcus went on to praise the service

provided by Passivent throughout

the project, having supplied and

commissioned the system on time. He

adds: “Ray, Passivent’s commissioning

engineer, was instrumental in the

project’s success. His expertise,

professionalism and dedication were

exceptional throughout. He went above

and beyond to ensure the system was

installed and functioning perfectly, and

his proactive support was invaluable. We

are thrilled with the outcome and highly

recommend Passivent for its products

and outstanding team.”

FROM WARDROBES TO WEATHERPROOF DECKING, WEST FRASER HAS PRODUCTS

FOR ALL HOUSEBUILDERS

With UK house prices rising, housebuilders and their

supply chain partners are under pressure to increase the

level of completions and meet demand. Timber panel

product specialist West Fraser is well placed to help

customers of all sizes respond, from those embracing

modern methods of construction as well as those

employing traditional building techniques.

West Fraser’s product range encompasses multiple

grades of MDF used for kitchens and other interior fit-out

work, to its ubiquitous SterlingOSB Zero,and the super

tough CaberDek, which offers 60 days’ exposure resistance.

The company has been investing heavily in improving

sustainability while also enhancing service levels.

Not only is the production process for SterlingOSB Zero

free from any added formaldehyde, it is made in plants

where all the energy comes from guaranteed renewable

sources, while efforts continue to drastically reduce the use

of diesel fuels in favour of electric powered fork-lifts and

loaders.

The Inverness plant is on track to achieve its 2030

sustainability targets within the next year, having replaced

the use of gas for the drying plant and investing in biomass

technology. Other sites are also making good progress on

their own road maps to net zero.

West Fraser’s products make significant contributions

to cutting carbon emissions by reducing waste, both in

customers’ factories and on site. Products like CaberFloor,

CaberDek and SterlingOSB Zero are dimensionally accurate

as well as rugged in use, so contractors need to spend far

less time on alignment or cutting. Consistency of size is

also of enormous value to the suppliers of timber frame wall

panel systems, including roof and floor cassettes or SIPs.

All West Fraser panel products produced in the UK

are net carbon negative and manufactured in mills with ISO

14001 accreditation. Responsibly sourced, the panels are

FSC certified and created from locally grown timber.

CASE STUDIES

TIMBER FRAME CREATES SEAMLESS EXTENSION FOR BRISTOL CARE HOME

An extension project at the Waverley Gardens extra care

housing scheme in Bristol saw timber frame selected as the

best possible construction method. To deliver this, main

contractor EG Carter & Co turned to Taylor Lane Timber

Frame, whose advanced wall panel system and I-Joist

cassettes were used to add 62 flats and a larger restaurant

area.

Waverley Gardens, run by Brunelcare, helps people

live independently later in life. Following the extension, the

development has 108 self-contained apartments, comprising

one- and two-bed flats, with 20 properties available for

exclusive shared ownership. There are also a full range of

on-site facilities including hair salon, therapy room, shop,

and laundry.

Mark Harries, Associate Director at EG Carter & Co, says:

“The Waverley Gardens project was constructed on a tight,

urbanised site; so a timber frame superstructure was the

perfect solution. The use of timber frame also meant the

project could be handed over sooner.”

The tight site had little storage space, which Taylor Lane

had to factor in when sequencing the works, especially

towards the end. Good communication with all parties was

crucial, not least due to sharing the tower crane with other

trades. This required liaison with other sub-contractors to

ensure work could be carried out as planned.

Having to build the extension while residents were in-situ

was perhaps, the greatest challenge. Taylor Lane had to

ensure robust health and safety measures were in place,

including fire risk assessments. In high-risk locations, the

timber frame was cement boarded and FR-treated (flame

resistant treatment applied) for safeguarding.

The final task was to link the extension into the existing

building. Precision was key to guarantee a successful

connection. Manufactured in a factory controlled

environment, the timber frame wall panels, floors and roofs

are precision-engineered off-site, allowing for a reliable and

high-quality build to exact specifications.

TIME TO MASTER GAME-CHANGING

COLOUR THEORIES

To help you understand how colour theories work, Johanna Constantinou, Trends

Expert at Tapi Carpets & Floors, has shared tips and tricks to create the perfect

interior design colour palette in 2025.

Colour is one of the most powerful

tools in interior design, capable

of shaping moods, defining

spaces, and creating harmony within

a home. With 2,900 average monthly

searches online for ‘colour palette’,

many seek inspiration to understand the

impact colour can make.

At its core, colour theory involves the

strategic use of the colour wheel,

colour harmonies, and psychological

associations to encourage specific

emotions and atmospheres. From the

warmth of monochromatic tones to

the bold contrasts of complementary

hues, people need to balance elements

such as saturation, temperature, and

proportion must be balanced to achieve

a visually engaging space.

The 60-30-10 colour rule

“60-30-10 is a timeless guideline in

interior design that helps achieve a

balanced colour scheme in any room.

By allowing one colour to dominate,

the design maintains cohesion. This

versatile rule suggests dividing a room’s

colour palette into three proportions:

60% for the dominant colour, 30% for

the secondary colour, and 10% for the

accent colour,” explains Johanna.

The dominant colour should cover the

largest portion of the space – usually

around 60%. “The 60% colour serves

Colour theory involves

colour wheel, colour

harmonies, and

associations to

encourage specific

emotions.

as the foundation of the room and

sets the overall atmosphere. It’s often

used on walls, large furniture pieces,

or flooring. This colour should align with

the overall mood and purpose of the

room, whether it’s warm and welcoming

or cool and serene,” says Johanna.

A soft neutral like light beige or a pale

grey on the walls, for example, creates

a calming backdrop, ensuring the room

feels spacious. The secondary colour

makes up about 30% of the space and

adds depth and contrast to the dominant

colour. For example, a rich navy blue or a

warm earthy tone, such as rust, could be

used for the sofa or curtains, providing

contrast to soft, neutral walls.

Johanna adds: “The secondary shade

complements the dominant hue but is

usually a bit more striking, offering variety

without overwhelming the room. It is

often applied to larger pieces of furniture,

window treatments, or accent walls.”

The accent colour makes up the

remaining 10% of the space and should

be used sparingly to add vibrancy,

interest, and focal points. For example, a

vibrant mustard yellow or deep emerald

green, used in accessories such as

cushions, adds excitement and draws

attention to specific areas.

“The accent colour can be an

unexpected pop of colour that draws

attention to key features like artwork

or throw pillows. They can be bold

or vibrant, offering an opportunity to

experiment without overpowering the

room,” says Johanna.

The colour wheel

The colour wheel is used to understand

relationships between different colours. It

consists of primary colours (red, yellow,

blue), secondary colours (green, orange,

purple), and tertiary colours (red-orange

or yellow-green).

Complementary colours are those that

sit opposite each other on the wheel,

creating high contrast and vibrancy, and

making them ideal for dynamic areas

such as living rooms or creative spaces.

Analogous colours are those that sit next

to each other on the wheel. They are

harmonious and create serene, cohesive

environments, ideal for bedrooms.

“Monochromatic colours are variations

of a single colour, using tints, tones,

and shades, which create a soothing,

minimalist aesthetic that works well in

spaces that need to convey calmness

and simplicity, like bathrooms or modern

living rooms,” adds Johanna.

Balancing warm and cool colours

The warm vs. cool colours rule is a key

principle, helping people create spaces

with specific moods and atmospheres.

Johanna says: “Warm colours such as

red, orange, and yellow, create a sense

of energy, comfort, and warmth, making

them ideal for lively, social spaces.

Conversely, cool colours, such as blue,

green, and purple, induce a calming,

soothing effect, perfect for where

relaxation or focus is essential. While a

predominantly warm palette can make

a space feel inviting, adding cool tones

provides contrast and depth. Similarly,

a primarily cool-toned room can benefit

from warm accents to avoid feeling too

sterile or cold.”

TIMBER DESIGN AND

COMMERCIAL VIABILITY

For a long time, the industry has delved into the benefits

that building with timber offers the construction

industry, particularly from a sustainability perspective.

However, some of the most beneficial aspects of the

material lie within its commercial viability. In order to

get the best out of timber as a construction material in a

housebuilding sense, we must equip architects with the

knowledge required to make informed design

decisions. Here, Paul Newman, Technical Director from

the STA explains more.

By now, the construction industry

is more than aware of the crucial

need to prioritise sustainability

in projects. As such, timber has

emerged as a key material for achieving

the UK’s ambitious net zero targets,

particularly while also needing to

achieve its commitments to build over

300,000 homes per year. However, the

advantages of timber go far beyond just

its environmental benefits.

Timber-framed homes can be

constructed in as little as 15 weeks,

significantly faster than the 26-30

weeks typically required for masonry

or concrete methods. This accelerated

timeline results in substantial cost

savings, reduced project risks, and

increased predictability—key advantages

in an industry where efficiency is

paramount. Additionally, timber-framed

structures become weather-tight 6 to

10 weeks sooner than masonry homes,

enabling internal work to commence and

finish much earlier.

In addition to the time-based benefits

of timber frame, it also generates far

less waste meaning minimal landfill

contributions and fewer weather

delays. The just in time approach to

offsite manufacturing enhances project

management, enabling shorter build

times and lower costs. These operational

efficiencies make timber a commercially

attractive option, especially in affordable

housing and high-volume projects.

competency, skills and informed decision

making on designs and planning.

The UK Government’s Timber in

Construction (TiC) Policy Roadmap

highlighted the importance of skills

and competency in priority theme

three: increasing skills, capacity and

competency across the supply chain.

To achieve widespread adoption of

timber, architects and designers must go

beyond simply substituting materials and

instead integrate timber-specific design

principles.

Architects must ensure that they

collaborate early with engineers,

clients, and contractors to align on best

practices while also possessing a good

understanding of the different timber

frame systems available, from timberframe

to SIPs. Of course, compliance

with fire, durability and acoustic

performance regulations is crucial,

as is the integration and adoption of

offsite manufacturing to leverage the

full potential of timber as a construction

material.

A well-trained workforce is crucial for

high-quality timber construction, and

the TiC Policy Roadmap highlights the

industry’s need to upskill professionals,

attract new talent, and ensure adequate

training for existing workers. However,

the sector faces several challenges,

including a lack of formal education

on timber construction in architectural

programs, a need for expanded

Continuing Professional Development

(CPD) initiatives focusing on timber

engineering and whole-life carbon

considerations, and a shortage of skilled

tradespeople trained in proper timber

system installation. To address these

gaps, industry bodies like the STA play a

vital role in providing resources, training,

and accreditation schemes.

The benefits of timber in construction

extend far beyond sustainability, offering

significant commercial advantages such

as faster build times, cost savings, and

improved project efficiency. However, to

fully harness its potential, architects and

designers must develop the necessary

skills and knowledge to integrate timberspecific

design principles effectively. The

UK Government’s Timber in Construction

Policy Roadmap underscores the

importance of upskilling the workforce,

expanding formal education, and

enhancing training initiatives to

drive wider adoption. By prioritising

competency, collaboration, and offsite

manufacturing, the industry can unlock

timber’s full value, ensuring it plays a

central role in meeting both housing

demands and sustainability targets. For

more information about the STA, visit

www.timefortimber.org

The advantages of timber construction

are clear, from viability in a commercial

sense to the sustainability benefits that

are so crucial to the industry. But how do

we achieve this transition successfully?

The key to this success hinges on

A NEW VISION FOR INDEPENDENT

LIVING IN CAMBRIDGESHIRE

In an era where retirement housing is evolving beyond the traditional, Rangeford

Villages’ latest development, Strawberry Fields in Cambridgeshire, is setting a new

benchmark for independent community living designs.

Strawberry Fields, Cambridgeshire,

is a new 100-acre site that

promises to be more than just

a place to live – it’s an integrated

community designed to offer a lifestyle

that encourages well-being, connectivity,

and modern luxury for its owners.

Officially launched in late 2024, the

development features 147 beautifully

designed homes, ranging from

sensitively designed bungalows to

spacious apartments, all incorporating

state-of-the-art amenities and the

creation of exclusive owner amenities.

With architecture inspired by the local

Cambridgeshire vernacular, the homes

have been seamlessly integrated into the

landscape, offering residents a sense of

belonging to both the community and

the natural environment around them.

The development’s design isn’t just

about aesthetics; it also prioritises

functionality and sustainability. The

homes offer state-of-the-art energy

efficient features including solar panels,

heat pumps, and triple glazing to

reduce carbon footprints. This focus on

sustainability is part of Rangeford’s wider

vision to create eco-conscious, energyefficient

spaces where retirees can thrive

without compromising on comfort or

style. The homes are all fully accessible,

with wide doorways, level access, and

integrated assistive technology such as

smart home features, emergency alert

systems, and automated lighting.

Strawberry Fields has been designed to

blend contemporary living with the area’s

rich agricultural heritage. The developers

have maintained and enhanced the

rural charm of the site, incorporating

open green spaces, meandering

walking paths, and scenic views of

the surrounding countryside. These

elements are intended to encourage

outdoor activity, fostering a healthy

lifestyle for its owners.

A strong sense of community

What stands Strawberry Fields apart

is its emphasis on community and

engagement, creating a vibrant, inclusive

environment where people can connect,

socialise, and pursue their passions. The

central hub of the village is designed to

be the heartbeat of the community, with

a village hall and amenities including a

wellbeing centre, gym, dance studio,

restaurant, coffee shop and bar, hair

and beauty salon. A full-time concierge

service ensures residents have access to

whatever they need.

The village features dedicated spaces

for mindfulness and meditation, with

a variety of social clubs, educational

talks, and workshops helping to

prevent the feelings of isolation that

can sometimes affect older adults.

Moreover, the proximity to the historic

city of Cambridge means residents have

easy access to a wealth of cultural,

educational, and healthcare facilities.

Care services are available on a bespoke

basis, ensuring that each resident’s

needs are met without the need to leave

the village. This includes domiciliary care,

housekeeping, and nursing support, all

delivered with the highest standards of

professionalism.

Supporting Local Economy

Beyond the benefits to owners,

Strawberry Fields is also set to have a

significant impact on the local economy.

From the construction phase to longterm

operations, the development will

create local employment opportunities

and provide a much-needed boost

to local businesses and suppliers.

Rangeford has also pledged to support

local charities and initiatives, ensuring

the development will continue to benefit

the wider Cambridgeshire area in the

long term.

Strawberry Fields represents a forwardthinking

approach to retirement living,

where design, wellness, community, and

sustainability come together in harmony.

Rangeford Villages has created a space

where retirees can live independently,

with the knowledge that help is always at

hand if needed, and where the emphasis

is firmly on a lifestyle that enriches every

aspect of life.

sustainable insulation to the UK and Ireland. Gramitherm

is the first insulation to be produced from grass, which

is sourced from public parks and grass verges then

combined with recycled jute fibres, plus a recycled

polyester binder. Each hectare of grass can produce

200m 3 of insulation.

Resistant to mould, Gramitherm has natural hygroscopic

properties that helps to regulate humidity and enhance

breathability. It has an Environmental Product Declaration

demonstrating that 1kg of Gramitherm sequesters 1.5kg of

CO 2

equivalent post production, making it a highly efficient

and eco-friendly choice.

Gramitherm can be installed in rafters, joists, walls,

ceilings and floors. The insulation is both flexible and rigid,

ensuring a snug fit without settlement. It has a high density

of 40kg/m 3 due to the fibrous structure of grass.

Gramitherm’s breathability and thermal performance

make it suitable for both newbuilds and retrofits. With a

thermal conductivity of 0.041W/mK and high heat storage

capacity, Gramitherm keeps buildings warm in winter and

cool in summer. It is available in 390mm and 580mm widths

at various thicknesses and can be cut to size easily.

Gramitherm has excellent acoustic properties,

absorbing 99% of sounds at 1000hertz and reducing noise

transmission.

HOSPITALS &

HEALTHCARE

ELEVATING HYGIENE AND DESIGN

IN HEALTHCARE SPACES

When it comes to healthcare design, the balance between hygiene standards, acoustic

performance and aesthetic appeal can be tricky. Here Zentia explains how well-designed

products can enhance both hygienic standards and the patient experience.

Healthcare facilities must uphold

the highest standards of

cleanliness while also creating

a sense of comfort and wellbeing for

patients, staff, and visitors. Despite

this understanding, hospital-acquired

infections (HAIs) remain a significant

challenge within healthcare settings,

with research indicating that airborne

bacteria and contaminants contribute to

the spread of infections, making ceiling

surfaces a critical element in infection

control strategies.

Moreover, compliance with healthcare

building regulations is essential. The NHS

Constitution mandates that all healthcare

organisations should “ensure that

services are provided in a clean and safe

environment that is fit for purpose, based

on national best practice”. The Health

Building Note (HBN) 00-10 provides

best practice guidance for the UK,

stating that healthcare facilities should

provide a “therapeutic environment in

which the overall design of the building

contributes to the process of healing and

reduces the risk of healthcare-associated

infections”. This guidance also sets out

the different requirements for ceiling

finishes in each type of hospital room

space.

The role of acoustic solutions in

healthcare

Beyond hygiene, the acoustic design of

healthcare spaces can also significantly

impact on a patient’s comfort and

wellbeing. Noise pollution in hospitals

is a well-documented concern, with a

number of different causes for excessive

sound including medical equipment,

patient movement and visitor activities.

Excessive noise levels can cause patient

stress and sleep disturbances, both of

which can negatively affect the healing

and recovery process. Staff are also not

immune to the negative effects of poor

acoustics in hospitals, with unmanaged

noise levels decreasing concentration

and increasing stress levels and the risk

of burnout.

The integration of wayfinding, zoning,

and acoustic control is also crucial in

optimising navigations and reducing

stress in complex hospital layouts.

Zentia’s ceiling solutions, for example,

can blend functionality with design,

helping to create an environment that

supports both patients’ psychological

wellbeing and the hospital’s operational

efficiency.

Zentia’s Biobloc range of ceiling tiles

have been carefully designed to meet the

rigorous demands of these healthcare

settings. The tiles feature a specialised

coating that actively inhibits the growth

of micro-organisms, making them

suitable for installation in clean rooms

with ISO 5 classification. They are also

resistant to moisture and can be cleaned

with standard disinfectants, supporting

infection control protocols that are

critical in hospitals, laboratories, and

other sensitive environments.

Within the Biobloc family are the Biobloc

Acoustic tiles, designed for areas where

infection risk is classified as ‘moderate

to high’. These tiles provide excellent

acoustic properties to minimise noise

pollution, contributing to a quieter and

more restful environment for patients

and staff.

Acoustic tiles provide solution for

Glasgow hospital

The Queen Elizabeth University

Hospital in Glasglow, one of the largest

acute hospitals in Europe, required a

ceiling solution that met the highest

standards of cleanability, resistance to

disinfectants, and acoustic performance.

The tiles selected for the project were

more than 110,000m 2 of Zentia’s

Biobloc Acoustic tile, which was used

throughout the hospital’s reception and

patient areas.

Zentia’s Biobloc range exemplifies the

importance and integration of hygiene

and design in healthcare environments.

supports the creation of hospital spaces

that are both safe and welcoming.

PROTECTING THE VULNERABLE

FROM SCALDING AND

BACTERIAL RISKS

Stephanie Allchurch,

Product Development

Manager at Altecnic

explores the importance of

getting it right when

specifying and designing

water systems in

healthcare settings.

While we hope that the

worst days of the

Coronavirus pandemic

are behind us, during

the toughest of times,

healthcare estates had to perform often

beyond their designed capacity. Now,

more than ever, we understand the

need to create reliable, safe and flexible

spaces if the NHS is to perform at its

best.

For health care specifiers, architects

and facilities managers, the ‘HTM04-

01 – Safe Water in Healthcare Premises’

regulation must be complied with to

ensure healthcare settings are safe for

vulnerable patients.

In particular, HTM04-01 part C -

Pseudomonas aeruginosa – advice for

augmented care units, describes how

‘hospital water is a recognised potential

source of Pseudomonas aeruginosa,

which is a microorganism that can

act as an opportunistic pathogen and

colonise and infect vulnerable patients.

Several outbreaks of P. aeruginosa have

been attributed to contaminated water

systems in hospitals’.

We know that legionnaire’s disease is

responsible for approximately 2-9% of

pneumonia cases and that the disease

is spread through the breathing in of

aerosolized water contaminated with

the legionella bacteria. This can be

created in environments such as hot

and cold water outlets, atomisers, wet

air conditioning plants, and whirlpool or

hydrotherapy baths.

Harmful bacteria, such as legionella,

grows in water systems where water

is stored between 20 – 60°C. So, it

makes sense to keep water stored and

distributed at temperatures above 60°C

to thermally disinfect systems, without

use of chemicals.

However, HBN 00-10 Part C – Sanitary

Assemblies advises that outlets above

46°C present a significant scalding risk

and should be labelled as such. It also

advises that thermostatic devices, such

as thermostatic mixing valves (TMVs),

should be used at each outlet to remove

the scalding risk.

According to the Child Accident

Prevention Trust, every year around 20

people die as a result of scalds caused

by hot bath water and a further 570

suffer serious scald injuries. Young

children and older people are most at

risk from bath water scalds because

their skin is thinner and therefore less

tolerant to higher water temperatures

than that of other age groups. As a

result, they sustain scalds more quickly,

at lower water temperatures and often

with a greater depth of burn.

Not only that, but ‘risk of scalding’ is

still on the NHS ‘Never Events’ list for

all organisations that provide NHS care.

The list highlights serious incidents

that are wholly preventable because

guidance or safety recommendations are

available at a national level and should

have been implemented by all healthcare

providers.

TMVs are used to blend hot and cold

water to maintain a set constant outlet

temperature. This ensures safe and

comfortable hand washing, shower and

bath temperatures, and signifi cantly

reduces the risk of scalding.

TMV regulatory standards in NHS

facilities

To store water at temperatures that will

thermally disinfect the water system, a

TMV must be specifi ed that adheres to

the strict testing regime of the TMV3 /

NHS D08 regulatory standard.

The TMV3 approval scheme provides

assurance that a TMV is tested and

deemed safe to use in a NHS setting.

This scheme applies to TMVs for use

in high-risk commercial healthcare

applications within the UK. These valves

off er a high level of protection, reacting

much more quickly in shutting off the

fl ow of water if the cold water fails,

or if a safe temperature is exceeded.

Testing bodies must ensure that the

valve adheres to the NHS D08 regulatory

standard, which ensures stable

temperature output despite varying

supply pressures and temperatures.

Other important factors taken into

consideration when carrying out

performance testing for TMV3

accreditation include:

• The company/manufacturer

applying for accreditation of the

valve must prove their compliance

with ISO 9001 (or equivalent quality

management system)

• The valve must feature the correct

markings making it identifi able in the

fi eld

• The installation and maintenance

documents must include information

stated by the scheme.

It is highly recommended that, once

installed, TMV valves are checked and

maintained annually to ensure they are

still providing suffi cient scald protection.

The outlet temperature should be tested

to check there is no signifi cant change

(≤2°C) and the failsafe shut-off activates

as intended. If this is no longer the case,

a full TMV service plus recommissioning,

or replacement, will be required. The

valve and fi lters, strainers and any other

components forming the device should

also be inspected, cleaned, descaled

and disinfected.

The importance of thermal

disinfection

This approach addresses the thermal

disinfection of 95% of the water

system, but there are several places in

which harmful bacteria can still form.

One of these includes the dead leg of

pipe between the TMV and the outlet.

According to the HSE’s approved code

of practice and guidance on regulations

on controlling legionella bacteria in

water systems, operators should:

“Consider the individual nature of the

site and system as a whole, including

deadlegs and parts of the system used

intermittently. These should be included

because they can create particular

problems, as microbial growth can

go unnoticed. When they are brought

back online, they can cause heavy

contamination, which could disrupt the

effi cacy of the water treatment regime.”

For this reason, it is recommended that:

• TMVs are installed as close to the

water outlet as possible, mixing

water at the point of use where

possible

• Multiple TMVs should be used in

the case of multiple outlets; use of

a single TMV increases the risk of

bacteria growth.

Full thermal fl ushes of water systems,

right up to the outlet, are also strongly

recommended to prevent the growth of

harmful bacteria in the dead leg between

the TMV and the outlet. However, this

can be costly and take considerable

time in a facility with multiple outlets

and TMVs. This is because each valve

will need to be bypassed in order to

successfully complete the thermal

disinfection.

To give a real scenario setting of

the drawbacks to this traditional

complete thermal disinfection method,

consider the scenario of a dormant

ward needing to be recommissioned

to house vulnerable patients at short

notice – something that was not

uncommon during the Covid pandemic.

Clearly, in this case, these steps and

considerations impede the facilities and

operations managers ability to act swiftly

to recommission the treatment space

with access to clean water, distributed at

safe temperatures.

However, there is a WRAS-approved

and TMV3 / D08 NHS regulatory

certifi ed TMV that allows easy thermal

disinfection right to the outlet – removing

the time and cost of recommissioning

the valve. The Mixcal Carefl o Plus TMV

removes the need to take off the TMV

to ‘fl ush’ out the whole system, making

the process quicker and more effi cient.

Using a special tool and the manual

override function, thermal disinfection

can be performed through to the outlets,

enabling a complete rather than a partial

fl ush and preventing the growth of

harmful bacteria.

The Mixcal Carefl o Plus TMV has

been designed and made to meet the

requirements of BS 7942:2000 and the

NHS model engineering specifi cation

D08 for use in healthcare settings,

hospitals, care homes and schools.

TMVs already play a vital role in

keeping people safe by regulating

water temperatures. These latest

advancements in TMV technology take

that safety role even further by making

it easier and faster to carry out thermal

disinfection when needed.

CASE STUDIES

CUPACLAD ADDS A NATURAL DEFINITION TO BESPOKE COASTAL PROPERTIES

CUPA PIZARRAS’ CUPACLAD 101 RANDOM natural slate

rainscreen cladding has been installed across two semidetached

newbuild properties on the Jurassic Coastline.

Chosen to blend in with the surrounding environment, the

slate provides a sleek and natural finish, as well as the high

level of performance necessary to cope with the coastal

conditions.

The properties were built to replace a 1918 bungalow that

originally occupied the site, with a key planning stipulation

that the new construction had to maintain the look and feel

of the existing street. This meant the design needed to

create two properties with the appearance of one, single

bungalow.

The architects at AR Design Studio proposed two

semi-detached properties that fan out at the rear into a Y

shape, providing two homes that deliver both privacy and

space. Appearing as a single-storey pitched roof bungalow

from the front, the steeply sloping landscape allowed the

properties to have a lower ground floor.

For a contemporary finish and to complement

neighbouring properties, natural slate was requested for use

on the roof and for the cladding on the upper storey.

Anna Rezin, Architectural Designer at AR Design Studio,

says: “The natural slate played an important role in helping

to maintain the aesthetic and rhythm of the surrounding

environment. We would highly recommend the CUPACLAD

slate cladding, as its external finish is sleek and all the

fixings are concealed.”

CUPACLAD is a fully BBA approved, Class A1 noncombustible,

back ventilated and drained façade system,

offering architects and specifiers a myriad of design options

from traditional to contemporary. The system is sustainable

and ecological, thanks to the use of a natural material and

recyclable aluminium substructure. The natural slate goes

through a production process that requires no chemicals

and less water and energy than alternative roofing products.

This approach has resulted in the slate gaining BRE Global

Certification.

The CUPACLAD 101 series is designed with an invisible

fixing system to ensure that the natural slate is the main

feature of a façade. CUPACLAD 101 RANDOM comprises

three different slate sizes installed horizontally on to the

aluminium frame, creating a dynamic composition using

self-drilling screws.

FORBO FLOORING SOLUTIONS USED IN STUDENT LIVING REFURBISHMENT

16-18 Potterrow Student Living is a purpose-built student

accommodation for post-graduates located opposite

the University of Edinburgh Campus, with 151 studio

apartments. Previously consisting of cluster flats, Jasper

Sanders + Partners, together with ADP Architecture, were

appointed by management company Curlew Capital to

convert the building into a more sophisticated space.

The brief was to transform the building to studios, with

premium finishes to attract an international post graduate

demographic. Jasper Sanders + Partners specified a broad

range of Forbo’s commercial flooring brands throughout the

scheme.

Creative Director Rebecca Finney explains: “We have a

longstanding partnership with Forbo and frequently specify

their products due to their versatility and durability.

“The texture and colours of Tessera Cloudscape,

specified in Stormy Weather, Mistral Gale, and Sirocco Blue,

perfectly suited the scheme with their rich texture, depth

of pattern and colour. This was specified for the communal

corridors and lift lobbies to add contrast and tactile feel.

Tessera is durable, easy to clean and reduces impact

sound. It is also a modular solution, meaning that if any

of the tiles needed replacing it is quick and easy to do so

without needing to replace the entire area.”

Forbo’s Marmoleum was also used extensively, including

within the studio apartments and entrance arrival area.

BRICKCLAD BRINGS TRADITIONAL

AESTHETIC TO

CONTEMPORARY HOTEL

A contemporary hotel in Liverpool has been designed to combine the city’s

traditional heritage with contemporary luxury using Shackerley’s BrickClad façade

system. Specify & Build reports.

Constructed on the site of a former

car park, the 133-room Halyard

Hotel in Liverpool is a four-star

boutique hotel designed by architect firm

ICA, located close to Liverpool’s famous

Albert Dock. Part of IHG’s Vignette

Collection, the hotel adds a modern twist

to the local area with a brick façade that

complements the type used to construct

the historic docks to capture the city’s

mercantile heritage.

The patented, mechanically fixed

BrickClad façade system from

Shackerley combines fired clay bricks

with the façade specialist’s Queens

award-winning SureClad primary support

system and an innovative steel cassette

profile. The façade system provides

the durability, aesthetics and longevity

of traditional brick construction, while

offering the design, buildability, speed of

installation, and consistency benefits of a

mechanically fixed façade system.

It was the façade installer for the project,

Task Contract Services, that put forward

the Shackerley BrickClad system as a

solution for the Halyard Hotel, having

used the company’s SureClad porcelain

stone panel system on previous projects.

Bespoke specification

Shackerley worked closely with the

architects, who originally specified a

narrow 50mm high Roman format brick

for the façade. The Shackerley team

developed a bespoke solution to create

the same longitudinal visual effect for the

brick façade with two extra-long brick

sizes – 277x65mm and 269 x65mm

– from the BrickClad Saxony range.

This solution successfully achieved

the architectural style required for the

2250m 2 façade, while providing the

speed and ease of installation benefits of

a robust and hardwearing mechanically

fixed system.

The patented cassette profiles for

The patented cassette

profiles for the BrickClad

the BrickClad façade system are

manufactured in-house by Shackerley

using the company’s bespoke rollforming

machines. The system is

usually supplied with Magnelis steel

cassette profiles as standard because

this type of steel has been treated with

a combination of zinc, aluminium and

magnesium, which provides many

times more corrosion resistance than

galvanisation and creates a self-healing

coating to protect cut edges and against

nicks or scratches that could be incurred

on site. For the Halyard Hotel project,

however, the specification required

a stainless steel cassette profile due

to the coastal location and planning

requirements, which was made to order

at Shackerley’s factories.

Shackerley also produces a range of

brick details for the BrickClad facade

system at its factories in Lancashire. The

specification for the Halyard Hotel called

for a large number of preformed corners,

which contributed both to the buildability

and speed of installation on site, and the

consistently high-end aesthetic of the

completed façade.

Smooth installation

The project also benefitted from the

SureClad primary support brackets,

which create a supporting grid for

SureClad ‘T’ profile extrusions. The ‘T’

profiles are inserted into these brackets

and aligned to ensure planarity, before

being secured with stainless steel fixings.

As Task Contract Services have installed

Shackerley’s SureClad façade systems

on a wide range of previous projects,

the installation team was already

familiar with this process, despite the

Halyard Hotel in Liverpool being its first

BrickClad project. After fixing the vertical

‘T’ profiles, the installation team fixed

the BrickClad cassette profiles to the

SureClad support framework ready to

receive the BrickClad Saxony bricks. The

bricks were then fitted into the precisionmanufactured

BrickClad cassettes, with

the top lip of each Saxony brick fitted

into the upper recess of the cassette. A

rubber mallet was then used to engage

the bricks securely in the BrickClad

cassette rail, prior to pointing with

specially formulated lime/sand pointing

mortar.

The finished façade achieves the look,

texture and enduring quality of local

heritage buildings, while enabling the use

of contemporary construction techniques

and ensuring compliance with current

building standards.

WEATHER THE STORM OF

CLIMATE CHANGE

With recent changing

weather conditions, Mark

Parsons, Technical Director at

Russell Roof Tiles, is urging

the industry to consider the

climate when working on

roofing specifications.

Over the last decade the UK has

experienced a huge change

in climate, with fluctuating

temperatures creating complications for

the industry and requiring specification

guidelines to be reassessed. January

2025 defied expectations and became

the world’s warmest on record, with

temperatures 2.0°C above predictions

despite forecasts of a cooler start to

2025. This came after a record-breaking

2024, with southern England seeing its

wettest autumn since records began.

A building’s location, structure and use,

alongside regional weather trends, are

some of the biggest factors to consider

when specifying a roofing solution. The

major shift in climate in the last few

years means solutions that may have

worked previously to combat extreme

weather conditions could no longer be

effective. Current weather patterns must

be considered during the specification

process to avoid the installation of

unsuitable roof products and ensure

optimal performance and safety.

If specified incorrectly, severe weather

patterns can significantly influence the

longevity and performance of roofing

systems. Prolonged exposure to harsh

climates such as excessive sunlight,

heavy rainfall, and high winds, can lead

to costly wear and tear overtime.

While strong winds are the most

common weather condition to affect

roofing – causing uplift, dislodging tiles

and damaging structures – excessive

sunlight, heat, rainfall and ice can be just

as detrimental. A well-designed pitched

roof will protect a structure from solar

radiation during warm weather, ensuring

the building doesn’t overheat. While, in

cold spells, it can successfully protect

against wind-driven rain and snow.

When considering materials and

components for newbuilds or reroofing

projects, it is essential to

choose products with a proven track

record from a reputable manufacturer.

Specified products must also be made

from durable, high-quality material to

ensure they can withstand all weather

conditions.

MODULAR ROOF SYSTEM MAKES

ENGINEERING CHALLENGE SIMPLE

Smartroof, a provider of offsite manufactured, modular ‘room-in-roof’ systems, has

completed its largest and most complex single house project to date as part of a

new property in Northamptonshire. Specify & Build reports.

Located in a picturesque

Northamptonshire parkland

setting, this arts-and-crafts styled

home presented unique engineering

challenges and logistical site issues that

complicated the roofing requirements

from the start. This included complex

design requirements, limited site access,

and proximity to an airfield that meant

any crane use had to be pre-approved.

The project, carried out for developer

Clayson Country Homes, was designed

by architects LMR Designs and

included several architectural features.

Smartroof’s solution centred on the

collaborative effort between its design

team, the architect and developer, and

structural engineer Simply Structural

Engineering.

A distinctive feature of the roof was the

integration of multiple working chimneys

which, along with custom-designed steel

beams supporting the roof cassettes,

designed by Smartroof, added

complexity to the manufacturing and

installation of this hybrid roofing system.

Adding drama with a vaulted ceiling

Each roof section and cassette

were unique, requiring precision

in manufacturing, transport, and

synchronised installation. The intricate

design involved multiple levels, styles

and stages incorporated in the build.

The vaulted ceilings, which included

a dramatic full height vaulted ceiling

reaching 4.8 metres in height,

necessitated roofing sections with in-lay

valleys and hidden box gutters.

Throughout the project, close

collaboration was crucial between

Smartroof, the developer, and the

site engineers. Regular meetings and

site visits were conducted to verify

measurements, discuss emerging

challenges and ensure the solutions

were fit for purpose. This ongoing

communication and flexible approach

to design and manufacturing allowed

Smartroof to adapt to any unforeseen

issues and keep this ambitious project

on track.

All project components were designed

by Smartroof and manufactured in its

state-of-the-art production facility in

Derbyshire. The offsite manufacturing

process offered significant advantages

including enhanced precision and quality

control, improved health and safety, and

the minimisation of material waste. By

prefabricating as much as possible, the

Smartroof system significantly reduced

on-site construction time and improved

overall safety during installation. The

efficient use of the limited site space was

essential, with close monitoring of the

crane placement and layout by all teams

making the installation smoother.

“This was one of our most ambitious

housing projects to date,” said

Smartroof’s Head of Contracts, Jamie

Bremner. “The complexity of this site

demanded proactive communication

between engineers, designers and site

managers. With the limited availability

of cranes, our design approach

The ceilings included a

dramatic full-height

vaulted ceiling that

stood at 4.8 metres.

provided an effective solution, ensuring

the project remained on schedule

without compromising on quality. This

collaboration demonstrated the expertise

and adaptability of team Smartroof,

delivering exceptional results under

challenging circumstances.”

The completed project exemplifies

Smartroof’s capabilities in delivering

complex challenges through innovation,

collaboration, and expertise, providing a

bespoke solution that addressed multiple

architectural and logistical challenges.

BEYOND COMPLIANCE: HOW

PRODUCT TESTING IS

RESHAPING SAFETY

Mike Vaczi, Technical Director at SOPREMA UK, discusses the changing face of

product certification and asks what the future could hold.

The construction industry stands

at a crucial turning point in its

approach to building safety and

product verification. Recent years have

seen unprecedented changes in how

we evaluate and certify construction

materials, driven by growing awareness

of environmental imperatives and

the Grenfell Tower tragedy. These

shifts have fundamentally altered the

responsibilities of manufacturers and

specifiers in ensuring building safety

and sustainability, and elevated the

importance of thorough testing and

independent verification.

The complexity of modern construction

materials and systems demands robust

verification processes. Every component

in a building must work in harmony with

others while maintaining its performance

characteristics throughout its service

life. This complexity is multiplied when

considering factors such as fire safety,

thermal performance and environmental

impact.

Independent certification plays a crucial

role in giving specifiers confidence in the

products they choose. Industry research

highlights that professional confidence

in products is intrinsically linked to the

availability of comprehensive, third-party

verified test data, but among the key

findings of the Hackitt Review was a

fundamental weakness in product testing

and certification. It found that many

products and systems were not being

properly tested, leading to inappropriate

or unsafe materials being used on

buildings.

The importance of independent

testing and certification is increasingly

recognised by specifiers and is a key

aspect of the Building Safety Act’s

Golden Thread requirements, which

demand accurate, trusted information

throughout a building’s lifecycle.

This becomes even more critical when

considering high-risk buildings, which

include structures at least 18 metres in

height or seven storeys tall containing

two or more residential units. For these

buildings, the Act establishes stringent

requirements for product information

and verification, making robust testing

and certification not just beneficial but

essential for regulatory compliance.

Product testing and certification

When it comes to roofing, façade and

insulation products, one of the most

important elements is ensuring that

products undergo testing as a system,

with all components installed as they

will be on a building. This allows the true

fire performance to be established, as

the interaction of different materials will

influence the penetration and spread

of flame. Any changes in the build-up,

such as a different substrate or thickness

of insulation, can alter how the system

performs in the event of a fire.

Documentation and transparency form

another critical aspect of effective

certification. The Code for Construction

Product Information (CCPI) emphasises

the importance of clear, accurate and

unambiguous product information.

This includes detailed specifications,

installation guidelines and performance

data that must be regularly updated and

readily accessible to all stakeholders in

the construction process.

Equally critical is the competency

of those involved in the testing and

verification process. The Building Safety

Act requires the clear demonstration

of competence for all duty holders.

This extends to those conducting and

overseeing product testing to ensure

that the certification process itself

maintains the highest standards of

professionalism.

The Gateway process introduced by the

Building Safety Act further emphasises

the importance of thorough product

testing and certification. Gateway

2 requires detailed technical and

product safety information before any

work can commence on site, making

it essential for manufacturers to

maintain comprehensive test data and

certification documentation.

SOPREMA, for example, has invested

significant time and capital in thirdparty

testing on all products within its

appropriate systems. Currently, more

than 200 system variations have been

tested and passed to BRoofT4, the

highest classification of fire performance.

This test data has also been certified by

the British Board of Agrément.

For more than 100 years, SOPREMA

has participated in the industry’s journey

toward more rigorous standards,

reflecting a broader recognition that

transparency and accountability

in construction products are

fundamental to achieving both safety

and sustainability goals. Successful

implementation of these depends

on close collaboration between

manufacturers, certification bodies and

industry stakeholders.

ROOFING & CLADDING

LEARNING LESSONS FROM

GERMANY

Designed by German architectural

practice MONO Architekten,

the extension of the Free

Waldorf School in Prenzlauer Berg,

Berlin, marked a distinct departure

from the site’s original architectural

style. Tasked with extending a 1970s

prefabricated building spanning five

storeys, the architects opted for a more

contemporary and dynamic appearance.

Stretching towards the sports hall,

the extension provides the school’s

courtyard with a structural back to the

street and a clear centre. The projections

and recesses create different outdoor

areas for various uses. A cluster of

pentagonal structures in different sizes

join together to form the unusual building

with roof slopes designed in different

directions.

With sustainability at the core of the

project, MONO Architekten specified

natural and renewable materials

wherever possible. The extension’s

structures are timber framed and the

outer walls filled with building straw

and plastered with clay. Untreated larch

wood planks of various widths serve as

exterior cladding to evoke the feeling

of a calm oasis in the middle of the

busy European capital. Coloured clay

plaster, wooden floors and wall heating

integrated into the outer clay walls create

a welcoming interior environment.

No ordinary roof

The entire roof area, including the

pentagonal structures, are topped with

green roofs to emulate the appearance

of lush, mossy stones and provide more

space for nature. A mix of low-growing

herb grasses was selected, which during

flowering season create a colourful

display for the children while attracting

pollinators to improve local biodiversity.

The green roofs offer additional benefits,

particularly in the urban setting. As well

as having a positive impact on people’s

health and wellbeing, the roofs help to

mitigate the urban heat island effect by

returning moisture to the environment

while providing good thermal and sound

insulation.

Sustainable waterproofing

In line with the architect’s creative

vision, the roofing membrane for the

new extension had to be sustainable,

efficient, versatile and flexible, offering a

perfect fit for the irregular shapes of the

building. It also had to be lightweight

and robust enough to provide a durable

foundation for the green roof system.

To meet these needs, Elevate’s

RubberGard EPDM single-ply roofing

membrane was specified. Made of

synthetic rubber, EPDM membranes

are designed for waterproofing flat and

low slope roofs. Its sustainable features

are widely recognised by international

institutions such as Greenpeace, and

the Dutch Institute for Building Biology

and Ecology (NIBE) have named it

as the roofing membrane with the

least environmental impact, offering a

durable, long-term solution for modern

architecture.

In its latest evaluation, NIBE states

that EPDM roofing membranes are the

most environmentally friendly choice

for flat roofs. Carried out every two

years, the analysis compares the initial

costs (material and installation costs)

as well as all hidden environmental

costs (raw material consumption,

energy consumption during production)

of roofing membranes from different

manufacturers. No harmful substances

are released during or after the

installation of an EPDM roofing

membrane, making it safe for rainwater

harvesting. Thanks to an improved

formulation, the release of carbon during

operational use has also been almost

eliminated.

The longevity of EPDM single-ply

roofing membranes has also increased.

The absence of plasticisers allows the

membrane to retain its flexibility without

the risk of migration, which can lead to

cracking, flaking and ultimately the failure

of the roof surface. The membrane will

return to its original shape and maintain

its performance after any expansions or

retractions caused by severe weather,

ensuring it can adapt to the roofs’

irregular shapes.

EPDM roof membranes evaluated in

Central European climatic region have

been independently studied with the

conclusion that a service life beyond 50

years may be expected.

ROOFING SOLUTION OFFERS LOW

MAINTENANCE SUSTAINABILITY

FOR CITY LIVING

The RESITRIX waterproofing system has

been specified as part of a luxury

residential development in Edinburgh,

offering sustainability and a long service

life for residents.

Located in the prestigious Barnton area of Edinburgh, The

Avenue is a luxury residential development with a mix

of apartments penthouses and villas, built by Cruden

Homes. Winner of a coveted NextGeneration Project Gold

Award for sustainability, the project specified the RESITRIX

waterproofing systems from CARLISLE for the roof and terrace

areas of both the apartment blocks and the villas.

It was important that the roofing system chosen for the project

could provide an extended service life and low maintenance,

to align with the calibre of the development, the expectations

of occupiers, whole-life cost management of the assets, and

the prestige of the location. RESITRIX is a hybrid, single-ply

membrane that combines the durability of a high-performance

bituminous membrane with the flexibility and elasticity of EPDM

in a single installation.

The system was recommended by roofing contractor Site

Roofing, previously known as Site Sealants, because the

company has used the system on a number of previous

projects and it has become their preferred option for buildings

that require a high-performance roofing solution.

A versatile, durable solution

RESITRIX enables the specification of a single membrane for

both roof and terrace areas. The roof areas include walkable

terraces, requiring a robust system that could cope with these

additional requirements. With proven performance during

both the build and operational phase, RESITRIX offered the

necessary durability, in particular its resilience to withstand

trafficking by construction teams during the build.

CARLISLE was able to supply the project from UK stock,

which enabled the roofing contractor to purchase the

required materials and store them off-site. This meant that the

contractor could draw down the materials needed on a just-intime

basis for the city centre site, making the project logistics

easier.

One of the key advantages of using RESITRIX for the project

was that the system requires no open flames, reducing health

and safety risk for all personnel on site, along with the potential

risk to the buildings. The system is fully bonded to the surface,

with a hot air gun used to seal the laps and complete the

details.

RESITRIX enables the specification of a

single membrane for both roof and

terrace areas

The Site Roofing team prepared the deck and then applied

CARLISLE’s FG35 Primer, allowing it to dry before rolling out

the RESITRIX SKW full bond membrane. RESITRIX SKW is

a self-adhering single-ply membrane with a peelable release

film for easy installation. Once the membrane is rolled, the

installation team scores the release paper to ensure a secure

bond between the substrate and the membrane. The laps and

details are then heat welded using a hot air gun.

Laura Duncan, Commercial Director of Site Roofing, says:

“We know that we can rely on the RESITRIX system as a

robust waterproofing membrane for which we can provide a

warranty with confidence. It gives us trouble-free installation

and is a complete system, enabling us to specify RESITRIX for

almost any flat roof requirement, including warm roofs, inverted

roofs, roofs with complex detailing, green roofs, podiums, and

balconies.”

Shail Chauhan, CARLISLE’s Marketing Manager, adds:

“The Avenue is an excellent example of the use of a highperformance

single ply system for a low-density, highvalue

residential development, where the calibre of design,

specification and construction are critical to securing occupiers

and maintaining the prestige of the accommodation for the

long-term.

“RESITRIX is EPD-certified, DGNB-compliant, and Green

Label certificated, and recognised as one of the most highperforming

single products for use on flat roofs in terms

of reduced environmental impact because it contains no

plasticisers and releases no harmful chemicals, while providing

an extended service life. Specification of this innovative system

for the roof at The Avenue contributes to the sustainability

credentials of the development.”

STAND OUT WITH WALK-IN

PANTRIES AND

CREATIVE COLOURS

Michael Marriott, CEO of Waterline Distribution, explores the

latest kitchen trends and how specifiers can capitalise on

them to stand out in a competitive market.

Kitchens remain the heart of the

UK home, with homeowners

increasingly choosing properties

based on the kitchen space. As the

trend for large, open plan kitchens and

living areas continues, making the right

specification choices is becoming more

important than ever to create a space

that will attract potential buyers and

maximise the potential purchase price.

Walk-in pantries have become a

highly sought-after kitchen feature as

homeowners look to create stylish,

practical and super-organised storage

spaces that can be cleverly concealed

behind closed doors. Available in a

variety of configurations, walk-in pantries

and breakfast cupboards offer versatile

storage options, as well as room for

compact appliances such as a coffee

machine, making them an appealing

proposition in apartments as well as

family houses.

Creative colour combinations

The trend for using cabinetry to bring

character to the kitchen isn’t going

anywhere as homeowners seek to create

eye-catching designs by mixing and

matching colours. Combining darker

colours such as Claret with paler shades

like Blush, for example, will create a

timeless look.

Maximise ceiling height

Homeowners and designers are also

thinking smarter about how to make the

most out of the space available. We’re

now seeing a big trend for kitchens

that provide more usable storage,

whether that be floor-to-ceiling cabinets

or strategically placed wall units that

maximise the height of the ceiling. It’s

all about getting more out of what you

already have, carefully considering

storage requirements and tailoring them

to suit the requirements of different

house buyers to create a more coveted,

personalised design.

The devil really is in the detail as

homeowners increasingly look to

bring style and personalisation to their

kitchens. This is also putting kitchen

hardware in the spotlight as a mix-andmatch

approach is enabling designers

and specifiers to create tailored kitchen

designs.

Connected appliances

High-tech appliances are also becoming

much more mainstream in the kitchen

as the consumer appetite for connected

products continues to grow. This is an

appliance trend that’s here to stay as

homeowners become increasingly tech

savvy and opt for intelligent models that

prioritise performance, sustainability and

convenience. Offering them even as part

of a contract kitchen design will elevate

your offering and provide house buyers

with an appliance package that will meet

their needs for many years to come.

Vented hobs

Finally, there’s also growing demand for

flexible vented hobs that offer the best

of both worlds as homeowners embrace

sleek, streamlined appliance solutions.

Combining an induction hob and

extractor, they provide a subtler way to

clear the air and, as overhead extraction

is not required, allows statement lighting

to be incorporated into kitchen designs,

which has become a highly sought after

feature among consumers.

DON’T UNDERESTIMATE THE

IMPORTANCE OF SINK DESIGN

Daniel Boulton,

Procurement Manager

at Clearwater, reveals

2025’s biggest kitchen sink

trends.

The importance of functional,

well-designed sinks and taps

should never be underestimated

in a modern kitchen. As two of the

most frequently used products in any

kitchen, they need to perform brilliantly,

look fantastic and, now more than

ever, offer real longevity and be easy

for homeowners to clean and maintain.

Manufacturers such as Clearwater have

risen to the challenge and the latest

generation of sinks not only tick all these

boxes but also help to optimise space.

Over the last few years, the demand

for multifunctional sinks has grown

significantly and it’s a trend that will only

continue to gain momentum. With the

rise in open-plan living, kitchens are now

used for much more than food prep and

cooking tasks, and are fulfilling more

functions than ever before, from working

and relaxing to socialising and home

entertaining. As a result, multifunctional

products that can cater for a wide range

of requirements are more appealing than

ever.

Workstation sinks, which are designed

for food prep and cooking as well as

washing up, have become increasingly

popular as homeowners look for

multifunctional sinks with smart,

integrated accessories.

Designed to make kitchen spaces more

efficient, products such as Clearwater’s

multitasking Urban Smart sink combine

style with convenience. This stainlesssteel

sink comes with a host of customfit

accessories, including a sliding

wooden chopping board and stainless

steel trays. These ergonomic additions

rest neatly on double-level bowl ledges,

making food prep easier by giving users

more hands-free space for tasks such as

rinsing vegetables or straining pasta.

Space savers

It’s no secret that space can be

a challenge in many newbuilds.

Workstation sinks with high-quality,

custom-fit accessories provide a stylish,

space-saving solution and mean home

buyers no longer need to compromise

on aesthetics or ergonomics. With many

models available in a range of sizes –

Clearwater’s Urban Smart sink comes in

three options of 540mm, 660mm, and

800mm – specifiers can now find options

to suit a variety of needs.

While home buyers love the flexibility

and practicality of double and 1.5-bowl

sinks, they are not always viable in

smaller houses and apartments. That’s

one of the reasons that Clearwater

introduced the Kameo-X sink, which

features a compact design as well as the

benefits of multiple bowls. Fitting into a

600mm cabinet, it has a generous single

bowl and a separate drainage outlet,

which also acts as the sink’s overflow

to enable the main bowl to be used to

its maximum depth. It comes with the

‘Smart’ accessory rail system, with its

accessory ledge accommodating a

chopping board and folding stainless

steel draining mat to cater for an array of

tasks within a small space.

A choice of materials

Sinks are now recognised as design

focal points in the kitchen and, as

personalisation has become more

important, housebuyers are increasingly

looking for sinks that give them greater

opportunities to customise their kitchen.

While stainless steel remains popular,

different materials and finishes are now

readily available.

Ceramic sinks, for example, can bring

character to classic and contemporary

homes. They are particularly well suited

to modern Shaker-style kitchens, which

has helped fuel demand. The latest

generation of ceramic sinks embrace the

current trends for layered texture with

brands such as Clearwater meeting that

demand with fluted finishes available

on a variety of its British-made single,

double and 1.5 bowl models.

With colour now a mainstay in kitchen

design, housebuilders that offer steel

sinks in eye-catching finishes can

provide a real point of differentiation.

Clearwater’s PVD sinks come in ontrend

Brass, Copper and Black finishes,

benefiting from being durable and

hygienic as well as offering even more

choice.

WASHROOMS

CREATE A SPA RETREAT IN EVEN

THE SMALLEST SPACES

With careful planning specifiers can create the ‘spathroom’ look in even the most bijoux of

spaces, according to Ben Bryden, Sales & Marketing Director of RAK Ceramics UK.

The demand for spa-inspired

bathroom designs has risen

significantly. But while many of

us dream of large, luxurious open-plan

bathrooms complete with a roll-top

bath and spa shower, the reality is that

the average UK bathroom measures

little more than 2m x 2m. Despite these

space limitations, however, homeowners

are increasingly investing in features that

promote relaxation and well-being in

their own homes. This is also translating

through into newbuild and specification

projects, highlighting a growing trend

toward creating personal sanctuaries

that offer both comfort and luxury.

The ‘spathroom’ trend is mainly being

driven by an increased desire for

relaxation and self-care. People want to

create calming spaces at home where

they can unwind, with advances in

technology and stylish product design

options also playing a role, making it

easier to combine comfort with luxury.

Specifiers can create a spa-like retreat

by focusing on relaxation and tranquillity.

Start with calming colours such as soft

blues, greens, or earthy tones to set

a soothing mood. Then, incorporate

natural elements like wood and stone to

bring in a touch of nature.

Smart technology adds convenience,

such as touchscreen mirrors and smart

showers, while luxurious fixtures like

rain showers and freestanding baths

enhance the experience. Sleek, wallmounted

furniture with minimalist

designs add style and saves space.

Ambient lighting can be introduced

to create a relaxing atmosphere, with

accessories like heated towel rails and

built-in seating adding extra comfort.

It’s true to say that the spathroom trend

isn’t going anywhere and it’s influencing

the very latest product designs to better

suit users’ needs. Seamless solutions

such as recessed shelving and niches

are being re-imagined and now come

in a choice of stylish finishes such as

brushed brass, matt black and brushed

nickel, providing storage solutions that

are as practical as they are elegant.

What could more emulate a spa feeling

than an illuminated recess inside your

shower filled with luxurious toiletries?

We are also seeing luxury finishes

becoming more popular, with

consumers looking to add personality

to their bathroom as demand grows

for unique products that reflect users’

individual style. It’s a trend that is set

to gain momentum this year, with

metallics leading the way across basin

and brassware design as vanity units

increasingly become the focal point of

the bathroom.

Finishes such as brushed brass and

brushed nickel, along with matt black,

are creating that coveted relaxed-luxe

vibe and will likely drive the overall

aesthetic of the bathroom. Cohesive

designs will also remain popular with the

trend for metallic finishes fitting into this

seamlessly.

Tile drenching is another interior style

set to really make its mark on bathroom

design in 2025, which again helps to

create a spa-like ambience. People want

to experiment more with colour, pattern

and texture in new and exciting ways as

the trend for individualisation gains ever

more traction. We’re seeing consumers

embrace different finishes across floors,

walls and even ceilings.

The spa bathroom trend will likely evolve

with more personalised touches and

advanced tech. Natural and sustainable

materials will gain popularity, and the

focus will continue on blending luxury

with practicality to create relaxing,

unique spaces.

DESIGNING FOR ACCESSIBILITY:

WHY INCLUSIVE SHOWERS MATTER

Suzannah Adey, Product Marketing Manager at Mira Showers, highlights the role

that showers play in accessible living.

When housing fails to meet accessibility needs it has

significant societal and economic impacts. The

Greater London Authority’s November 2023 Housing

Research found that poor housing conditions in London alone

cost the NHS around £100 million annually. With more than

20% of the UK population living with a disability and nearly half

of those struggling to access their own living spaces, the need

for truly accessible housing has never been more apparent.

With an ageing population, the urgency to future-proof homes

is only growing. The ‘Future of an Ageing Population’ report

predicts that by 2040, nearly one in seven people in the UK

will be over 75 years old. Additionally, figures from the Royal

National Institute of Blind People (RNIB) estimate a 27% rise in

the number of people living with sight loss by 2035, reaching

2.8 million individuals. With these figures in mind, it’s clear that

landlords, housing providers, specifiers and manufacturers

should collaborate to create products that meet the needs of

people of all ages and abilities.

More than just a shower

For many a shower is a daily ritual – a moment of relaxation,

a fresh start in the morning, or a way to unwind at the end

of a long day. However, it can be a daunting challenge for

those with disabilities. But inclusive design can make all the

difference and accessible showers must cater to a range of

user needs, including those with limited mobility, dexterity, or

visual impairments. With the right shower, this difficult task

can be transformed into an independent, safe, and enjoyable

experience.

Maintaining independence is essential for wellbeing and

dignity, particularly for older individuals and those with mobility

challenges. Accessible showers can help users manage their

daily routine independently by incorporating visual and aural

cues. By enabling people to shower without assistance,

inclusively showers promote independence and dignity.

Prioritising safety

Accessible design isn’t just linked to providing individuals with

easier access to the shower. It’s also important to specify

a shower system that provides a consistent and safe water

temperature and flow at all times – reducing the chance of

sudden cold or hot blasts and the associated risk of scalding.

Showers with TMV3 approval provide enhanced thermal

control, reducing the likelihood of scalding and making them

ideal for accessible housing and social housing projects.

Additionally, adjustable water flow and temperature controls

allow users to tailor their experience to their own needs.

A shower designed for everyone

Developed in collaboration with the RNIB, the Mira Select Flex

is purpose-built to support users with limited dexterity, mobility,

and visual acuity. It offers key accessibility features such as

high-contrast colours and raised icons for improved visibility,

tactile graphics and an anti-reflective surface to reduce glare

and enhance usability. There is also push-button activation to

eliminate the need for complex adjustments, with ergonomic

controls and audible feedback to ensure ease of use. As the

only RNIB ‘Tried and Tested’ accredited mixer shower, the

Select Flex represents pioneering inclusive design. Whether

users are standing, seated, or assisted by a carer, the Mira

Select Flex is designed to provide a safe, comfortable, and

enhanced showering experience for all.

Mira Showers believes nobody should be excluded from the

enjoyment of a good shower. By designing with accessibility

in mind, the company ensures that everyone – regardless of

age or ability – can enjoy a comfortable, safe, and independent

showering experience. The future of housing should be

accessible, adaptable, and designed for all.

HEATING, PLUMBING &

VENTILATION

WHERE NEXT FOR GROUND

SOURCE HEAT PUMP

TECHNOLOGY?

Ground source heat pumps have evolved from a niche technology to a key pillar of

the UK’s net-zero strategy. Tamsin Lishman, CEO of Kensa, explores the potential of

ground source heat pumps as the company celebrates 25 years in the market.

With growing public interest,

ambitious decarbonisation

goals and a desire for more

efficient heating systems, ground source

heat pumps (GSHPs) are primed for

rapid expansion – especially as a way to

decarbonise UK heat at scale.

Heat pump adoption is steadily rising,

yet the UK still lags behind its ambitious

targets. In 2024, just under 100,000 heat

pumps were installed in the UK. This

is a great sign of progress and should

rightly be celebrated, but the reality is

we’re still far short of the government’s

600,000-per-year target by 2028.

Achieving this goal requires the right

policies to enable mass deployment

of solutions like networked GSHPs – a

model specifically designed to tackle the

decarbonising challenge at scale.

The networked heat pump model,

which Kensa has been installing for

well over a decade, connects multiple

properties with their own ground source

heat pump to a shared network of

boreholes, dramatically reducing the cost

of installation per home. By leveraging

this approach, GSHPs become a viable,

scalable solution for entire streets, highrise

apartment blocks and newbuild

developments. Crucially, this model can

help minimise upfront costs, reduce

strain on the electricity grid thanks to

the system’s high energy efficiency, and

future-proof homes by securing a heat

source for more than 100 years.

Social housing

Social housing providers have been

pioneers in adopting networked

heat pumps. We’ve worked with

numerous local authorities and housing

associations to install thousands of

GSHPs, demonstrating the system’s

reliability and affordability. The Shoebox

heat pump, designed specifically for

compact urban spaces, has been at the

heart of many of these projects.

Recent flagship projects include:

• Thurrock Council: A large-scale

networked heat pump installation for

273 flats across three tower blocks,

significantly reducing tenants’

energy bills.

• Clarion Housing Group: Upgrading

81 Edwardian-era flats in central

London with networked heat

pumps, proving it can decarbonise

old building types.

Government initiatives such as the Warm

Homes: Social Housing Fund (formerly

the Social Housing Decarbonisation

Fund) are vital in enabling this transition.

The funding being awarded later this

year will help thousands more transition

to clean heat, helping grow the sector,

but it’s essential there is long-term

funding certainty to ensure greater

adoption across the sector beyond this

next wave.

Newbuild developments

When implemented the Future Homes

Standard will transform the heat pump

sector, effectively tripling the size of

the market overnight, making it one

of the most important policies for

future heat pump deployment. As the

Standard phases out new gas boilers,

housebuilders will need to find costeffective

alternatives that comply with the

regulations. Networked heat pumps offer

a tried and tested solution for this sector,

which cost the same as gas when

installed at scale, put no additional strain

on the gas grid, and meet regulatory

requirements.

Networked heat pumps are already

proving successful for housebuilders. For

example, a 133-home project in Bristol,

completed in 2023, saw the installation

of networked heat pumps, giving each

new home a low-carbon heating system

that won’t need replacing in the coming

years.

Kensa’s partnership with utility provider

GTC ensures networked heat pumps

can be installed in new developments

without no increase in costs for

developers compared to gas. This

is achieved because of the system’s

high efficiencies, meaning there’s no

need for additional grid upgrades

– avoiding a potential headache for

developers switching to electrified

heating. Integrating this system for new

developments helps housebuilders

meet the Future Homes Standard

before it comes in and, crucially, helps

homeowners avoid the cost of ripping

out their gas system in the future.

Opportunities for the future

While momentum is growing, key

barriers remain including upfront costs,

policy uncertainty, and awareness of

how effective GSHPs are. However,

with government support, industry

collaboration, and continued innovation,

it will play a crucial role in decarbonising

heat.

NEW HOMES + NEW HEATING =

SUSTAINABLE LIVING

Sean Keleher, technical director at Navien UK, takes a look at what really matters

when recommending heating solutions for newbuild properties.

The mounting costs of energy

have been squeezing

homeowner’s budgets for

years, placing more focus

on improving and optimising

heating technology to deliver better

energy efficiency and reduce household

bills – with a key focus being placed on

newbuild properties.

Recent Uswitch research shows that

first-time buyers are generally getting

older, with an average age of 34 when

they first enter the property market.

Unsurprisingly this new generation

of tech-savvy and environmentally

conscious house-buying millennials is

changing how things are done. Typically,

those buying newbuilds are looking for

homes with high-efficiency ratings and

more advanced heating technology to

achieve even greater savings and a lower

carbon footprint.

But specifiers can go further to help

customers keep more money in their

back pockets as well as helping the

planet – especially in newbuild homes.

New policy drivers

The Labour government has set out an

ambitious plan to build 1.5 million new

homes across England in the next five

years, which has served as a wakeup

call for the construction industry

and presents the heating sector with

a significant opportunity to support

the housing sector in moving to more

sustainable heating solutions.

On top of its commitments to newbuild

homes, the government is also pushing

a more sustainable agenda. In the

Chancellor’s first budget she committed

£3.4 billion towards heat decarbonisation

and household energy efficiency over the

next three years. While some of this will

support fuel poverty initiatives and the

Boiler Upgrade Scheme in England and

Wales, a significant slice will also support

the growth of the heat pump industry.

Complementing this, the Department for

Energy Security & Net Zero has selected

six towns and cities across Leeds,

Plymouth, Bristol, Stockport, Sheffield

and London to participate in a £5.8m

pilot programme for the nation’s first

heat network zones.

The new schemes will use trailblazing

technology to provide heating. Excess

heat from data centres – which would

otherwise be wasted – will heat the

Old Oak and Park Royal Developments

in London. In Leeds, commercial

buildings will get their heating from a

nearby glass factory. The scheme is

focused on large commercial and public

buildings such as hospitals, universities,

hotels, supermarkets and office blocks,

demonstrating the technology at scale.

However, we could see future heat

network zones used for residential

properties.

smarter appliances, and boilers are

no exception. If they can control and

The government made it clear that they see the

future of heating as being smart, sustainable

and better connected, something we’re actively

supporting at Navien. Thanks to these changes,

there is a demand for more sustainable homes.

Popular features now include apps that

provide downloadable Home Energy

Management System (HEMS) reports,

offering consumers informed insights into

their energy consumption. Some apps,

such as Navien’s, also enable the user

to set up geofencing to a radius of 5km

from the home, meaning they can set

the boiler to switch on or off whenever

they cross that line. This results in

the property always being at the right

temperature when they return home –

without burning gas to heat an empty

property.

This government has made it clear that

they see the future of heating as being

smart, sustainable and better connected,

something we’re actively supporting at

Navien.

Modern solutions

Thanks to these changes there is

a push-and-pull demand for more

sustainable new homes – both the

drive from the government and the

changing needs of younger house

buyers. For anyone working on newbuild

developments, it is crucial to understand

these twin drivers for cost-effective

heating systems that enhance energy

efficiency and reduce utility bills while

also meeting the needs of a modern

household. So, what heating solutions

do you need to consider?

Combi boilers

Newbuild developments also address the

growing demand for multiple bathrooms

in each property. Research from Savills

indicates that this can lead to a price

premium of up to 20% per square foot.

To meet these demands, a system boiler

would traditionally be required, which

also means space must be set aside for

a water cylinder. However, this desire for

more hot water outlets does not mean

that specifiers have to recommend

system boilers. Modern combi boilers

are more than capable of meeting this

increased demand while still retaining

their efficiency and cost-saving benefits.

Ultimately, what you can get for your

money today seems to be shrinking,

especially in built-up urban areas.

Despite a sleek and modern design,

ideally no one wants to see a boiler on

show in their home; which is why the

space-saving features of combi boilers

are appealing. Their compact dimensions

make it easier to hide discretely in

locations like a kitchen cupboard or

under the stairs. It’s also a win-win for

installers, as combi boilers can save

time on installation because you don’t

need to fit a separate hot water cylinder

Smart diagnostics functionality also

means homeowners can use the app to

identify issues quickly, helping to prevent

a minor problem becoming a major

issue. And the installer doesn’t have to

worry about updating the system; ON AI

uses wireless technology to download

and install firmware-over-the-air updates.

Boilers with smart technology integration

enable homeowners to keep a close eye

on their energy use in real time, further

fostering an energy-conscious culture

within the household.

The adoption of cost-effective and hybrid

boiler systems in newbuilds represents

a significant opportunity to create

more sustainable living environments.

Together, these technologies help

newbuild homeowners achieve

sustainable living through efficient

heating solutions.

HEATING, PLUMBING &

VENTILATION

UNDERSTANDING AIRTIGHTNESS,

MOISTURE AND VENTILATION

Dave Judd, Technical Specification Advisor at Ecological Building Systems, explores

airtightness, active moisture control and effective ventilation in sustainable homes,

including Passivhaus projects.

Unwanted air leakage has been

proven to significantly increase

the space heating requirements of

a building, as well as making them less

comfortable, draughtier and less energy

efficient. Air leakage can also lead to

long-term problems in the building fabric,

resulting in interstitial condensation.

Airtightness is therefore one of the

essential components of modern

sustainable homes.

For designers and specifiers of

Passivhaus dwellings, the gold standard

is to achieve an air leakage rate of less

than 0.6 air changes per hour (ACH)

at 50Pa (Pascals of pressure). This

stringent target ensures that the building

envelope is highly sealed, therefore

minimising uncontrolled air movement

and maximising energy efficiency.

Ways to achieve airtightness

There are a number of approaches that

can ensure airtightness. The first step is

to identify potential air leakage areas at

the design stage. These include service

penetrations (such as electrical wiring

or plumbing connections), structural

junctions or a combination of the two. By

proactively addressing and sealing these

critical points, for example with products

like a Pro Clima Aerosana Visconn

airtight liquid membrane, a continuous

and reliable air barrier can be created.

Secondly, an airtight vapour control

membrane can be designed into the

build that responds accordingly to

humidity. Intelligent airtight membranes

such as Pro Clima Intello Plus have

proven themselves for over 20 years,

allowing over 100 times more moisture

vapour to pass through when humidity is

high within the structure to guard against

mould and moisture related issues.

Finally, high-quality air barrier tapes and

sealants are crucial to ensure airtightness

at joints, seams and penetrations.

These specialist products are designed

to withstand movement, temperature

fluctuations and exposure to moisture,

providing long-lasting airtightness

performance.

Quality control

Ensuring airtightness on-site requires

a dedicated approach to quality

control both in terms of processes

and materials. Airtightness materials

should have adequate certification

from the Passivhaus Institute, BBA or

other third-party test bodies. Early and

frequent inspections are essential to

identify and address any potential leaks,

as well as clear communication and

co-ordination among all trades involved

in the construction process. The use of

a blower door test can provide valuable

insights into the building’s airtightness

performance, allowing for remediation

efforts to be made during the build

process.

Intelligent moisture management

Understanding how moisture vapour

moves through different building

materials can help to maintain the

integrity of the building envelope through

intelligent moisture management of the

building fabric.

We expect to have to prevent moisture

from entering a building from the outside,

but there are many ways that moisture

can enter a building from the inside. This

includes convection, the installation of

damp construction materials, vapour

diffusion and flank diffusion (where water

vapour bypasses a vapour barrier at a

junction with a structural element (eg, an

unplastered chimney breast). A careful

balance needs to be struck between

the moisture loading of materials and

ensuring sufficient drying reserves. If

the moisture loading of a build exceeds

the drying reserves, structural damage

can occur. Building in adequate drying

reserves is therefore essential to prevent

long-term issues.

Intelligent vapour check membranes are

designed to provide humidity-variable

diffusion resistance. These sophisticated

internal membranes can adapt to

changing environmental humidity

levels, allowing the building fabric to

dry out when needed, while preventing

excessive moisture vapour intrusion in

winter months.

Effective ventilation

As well as airtightness, a healthy living

environment also needs to have careful

control of indoor humidity levels and an

effective ventilation system to prevent

condensation and mould growth. Natural

ventilation is generally not sufficient to

meet the strict ventilation requirements

of a Passivhaus, especially in colder

climates.

An effective ventilation system strikes

a balance between fresh filtered air

supply versus unnecessary air supply

causing excessive heat loss. It must also

control condensation through humidity

regulation and provide heat recovery

which lowers energy demand. Achieving

optimal airtightness and moisture control

is essential to create a high-performance

Passivhaus that delivers exceptional

comfort, energy efficiency and indoor air

quality.

THE COMPLEXITIES OF UK

ENERGY PROCUREMENT

Rinnai’s Chris Goggin

considers the roles

different energies will play

as we approach net zero

and the influence of

international energy

markets.

This document also provides further

objectives in adding clean power to

the UK national grid. Renewables

increasingly play a huge role in the UK

domestic energy mix. Off shore wind will

be increased to 43 – 50GW, onshore

wind will be expanded to 27-29GW,

while solar power capacity will also be

increased to 45 – 47GW.

HEATING, PLUMBING &

VENTILATION

International geopolitics heavily

infl uences global energy prices

and distribution routes, as well as

highlighting the commercially driven

nature of the global energy market.

The UK is moving towards clean

renewables that are not subject to cost

spikes nor the interfering geopolitics

that typically beset fossil fuels. In 2023,

the UK energy mix consisted of 36.7%

renewables, but by 2024 that share

increased to 43.1%.

The current plan by the UK government

is to increase naturally sourced energy

extraction such as solar and wind power

and to eventually cease fossil fuels. UK

oil and gas usage has dropped over the

last decade, with the energy mix falling

from 58.1% fossil fuels in 2014 to 32.2

in 2023%.

The government is particularly keen on

introducing an age of cheap and clean

electrical power. A recent government

report – ‘Clean Power 2030 Action plan:

A New Era of Clean Electricity’ – details

its ambition of fueling UK domiciles

and commercial properties with green

electricity at low cost.

A move towards renewables means

that UK domestic energy security is

strengthened, with net zero targets

being met and customer costs lowering

in time. Modern energy extraction and

distribution is a complex process driven

by geopolitics and corporate commercial

ambition. By expanding renewable

capacity, the UK aims to reduce reliance

on outside infl uences and to cease

operating as a net importer of energy.

However, the UK approach to energy

cultivation and distribution is heavily

reliant on external players who do not

necessarily have to abide by UK rules

and regulations.

THE VALUE OF VALVES

Richard Bateman, Product Marketing Manager for RWC, explores why valves are

critical to the delivery of effective plumbing systems in multi-occupancy buildings.

There has been real growth in

the number of multi-occupancy

buildings in recent years, largely

down to more people living in urban

areas. For these properties to be

effective and comfortable for every

occupant, it is important to optimise

their plumbing systems. Systems in

multi-occupancy buildings are generally

more complex than traditional one-home

domestic systems, but they can still

remain highly efficient through correct

specification and installation.

One of the most important product

categories that help deliver that goal

is valves, which allow for the effective

control of water throughout the building

and ensure every outlet and appliance

can draw on the water pressure required

to deliver water when needed.

Water will also enter the building at

much higher pressures than is safe for

individual outlets to handle, so controlling

this pressure with the right valves is

essential to performance, longevity and

user safety. With this in mind, there

are a number of specific valves that

should be included in multi-occupancy

specifications.

Floreg isolating valve

This product limits the flow rate of a

supply pipe to a set limit, conserving

water and limiting water wastage at

outlets. Used in individual outlets such

as taps and appliances, floreg isolating

valves allow plumbers to undertake

repairs and maintenance on specific

sections of the plumbing system without

having to shut off and drain large

sections of the system.

Easy to install and suitable for hot and

cold water use, they can be used to

maintain flow rates of the desired level,

which helps to save water and energy,

whilst providing even distribution when

supplying multiple outlets. Precise

flow control enables designers to size

systems accurately, with flow regulators

available from 4 to 15 litres/min. In

addition, interchangeable regulators

allow flow rates to be altered easily.

Pressure Reducing Valves (PRVs)

PRVs control and regulate water

pressure to reduce the risk of burst

pipes, flooding and damage to heating

systems and appliances. Vital for

delivering safe and stable water supplies,

PRVs also conserve energy by slowing

down the water pressure to reduce

the amount of water that comes out at

the point of use and include filters for

enhanced water purity. They should

be fitted at the point where the mains

pipework first enters the property, usually

the kitchen.

PRVs are particularly useful in multioccupancy

properties, where more water

is typically used than in a single domestic

property. This pressure can lead to

issues including pipe bursts.

Combination valves

Combination valves such as the onepiece

Tenant Valve Advance provides

a single solution that controls water

pressure and monitors water usage and

supply, while overcoming time and space

constraints.

Developed specially for multi-unit

buildings including residential high-rises

and office buildings, it delivers multiple

functions within one self-contained unit.

In fact, it includes all the elements that

make up a chain of valves – making

maintenance and servicing easier,

as there is no need to check every

connection point. The one-piece

cartridge design also reduces potential

leak points and installation labour costs.

Thermostatic Mixing Valves (TMVs)

Commonly found in many plumbing

systems, TMVs blend hot and cold

water to ensure safe and comfortable

water temperature, reducing the

risk of accidental injuries and

burns. They are multifunctional by

design, preventing backflow and

water impurities, as well as providing a

fail-safe/emergency shut off and

tamperproof adjustment setting.

Approved for basins, bidets, showers

and high pressure fill baths, TMVs are

quick and easy to install and provide

ultimate protection to end users, while

reducing water wastage and energy

consumption. Crucially, they allow hot

water systems to run at a high enough

temperature to prevent Legionella

bacteria from breeding. However, it is

crucial that TMVs are sized correctly for

the specific application, allowing mixed

water to be delivered at a constant rate

and an accurate set temperature, no

matter how many outlets are being used.

With a growing number of people

calling multi-occupancy properties

home, it is imperative that plumbing

and heating professionals have the

tools and resources they need to meet

the demands of such buildings. Valves

are a great place to start, ensuring

performance, safety, and stable systems

for users.

SOLID PASTE WATER TREATMENT TRANSFORMS WATER QUALITY IN

LIVERPOOL HOME

HEATING, PLUMBING &

VENTILATION PRODUCTS

DosaFil Residential Technologies has launched a range

of solid water treatment products for the UK residential

heating sector. Based on an existing system used in

commercial heating systems, the water treatment has

been downscaled in size for residential use, without

losing efficiency levels. Its recent installation in a 50-year

old detached home in Liverpool gave the company the

opportunity to showcase its effectiveness.

The residential property has a heating system that had

not been treated before and which had no magnetic filter

installed. The vented system comprised a hot water cylinder

and 10 radiators, two of which were towel radiators, and a

Baxi Solo 3 PFL70 boiler with an aluminium heat exchanger.

Pipework was a mix of copper and plastic. Independent

installer Dave Jones from Oil Gas Safe Ltd was asked to

carry out the work.

Firstly, a DosaFil B2 filter was fitted, with 22mm

compression connections installed on the return to the

boiler. The system was bled and refilled with fresh water via

the F&E tank in the loft area of the property. Then, the 60°C

water was left circulating for 30 minutes with filtration only.

A water sample was taken and sent for laboratory analysis,

with significant magnetic particle capture already evident on

the bar magnet.

Over the next few days the system was dosed with three

DR1 solid inhibitor capsules and one DR2 solid online

cleaner capsule, as well as a DR4 solid biocide capsule.

On day five a water sample was again taken and sent for

laboratory analysis.

The solid water treatment products performed

exceptionally well, the company says, and the whole

process was undertaken without the need for power flushing

any flushing to drain and refill – a huge reduction in water

consumption.

Dave says: “The results speak for themselves. It’s clear to

see that this package has made a significant improvement

to the system water quality and will continue to protect all

the components in the months ahead.”

SATISFYING THE NEED FOR SPEED

Neil Gaffney, Managing Director of Instantor, shares why the heating and plumbing

market is moving towards press solutions.

The need for the heating and

plumbing industry to increase the

speed of installations is causing a

surge in demand for press-fit solutions,

whether it is copper, multilayer pipe or

stainless steel. The growing shortage

of heating and plumbing engineers

means a greater focus on time-saving

technology so that engineers can get

more jobs done without compromising

on quality.

Instantor’s press solutions are designed

for specifiers looking for time-saving

solutions, with flame-free, quick and

reliable solutions for any scale of

plumbing project. Using a press tool, the

fitting is simply crimped securely on to

the pipe in a couple of seconds, saving

up to 35% of time on site compared to

more traditional methods.

The sector is also embracing the

importance of sustainability in

manufacturing, with copper press fittings

gaining popularity among specifiers and

installers who prioritise environmentally

conscious solutions by extending

product lifecycles.

As customers prioritise long-term value,

products with enhanced durability and

reliability are in high demand. This aligns

with both Instantor’s and Tucson’s

commitment to delivering robust

solutions that reduce maintenance

needs, extending product longevity. The

Instantor Press System, for example, is

backed by a 50-year warranty, providing

long-term reliability and assurance. Such

durable designs reduce the frequency

of replacements and the associated

environmental costs, ensuring that

customers receive high-quality, durable

solutions.

Streamlined solutions

Specifiers are seeking streamlined

solutions that reduce complexity and

increase efficiency. To meet this demand,

Tucson Pumps is simplifying its product

range by offering fewer SKUs, with each

designed to cover multiple applications.

This not only addresses customers’

needs for versatility but also reduces

production and inventory challenges for

greater sustainability.

Instantor manufactures heating and

plumbing products for specifiers that

focus on ease of installation. Tucson

Pumps provides powerful, efficient,

reliable and cost-effective pumps for

domestic dwellings and light commercial

pumping applications. Both brands are

part of the Sanbra Group.

RINNAI LOWERS COSTS AND ENVIRONMENTAL IMPACT

FOR LAUNDERETTE GROUP

Rinnai has recently provided a high-efficiency water

heating solution to a South Wales launderette which

needed to replace its old gas boiler as the property

wanted to lower operational costs and drive down

emissions.

The new owner wanted to install new coin-activated

washing machines and increase its capacity for more

customers, resulting in an increase in peak demand

loading for the hot water delivery system. The launderette

planned to have 10 washing machines in total, with two

different models differing in size and hot water

consumption.

The site currently employs a low kW rating gas boiler

with 144 litres of built-in internal storage, with the system

only able to provide 154 litres of peak demand. The

new coin-operated washing machines would see peak

demand increase the loading of hot water delivery

requirement to 276 litres. It also needed to be able to

recover from peak demand conditions within 40 minutes –

the average cycle of a coin operated commercial washing

machine.

Rinnai UK proposed a system consisting of an N1300

continuous flow water heater with an additional 300-litre

storage buffer to hold the peak demand for the washing

machines. This system can recover the entire buffer in as

little as 23 minutes.

MEETING THE LATEST

VENTILATION REQUIREMENTS IN

NEWBUILD HOMES

Ruth MacEachern, Product

Manager at EnviroVent,

looks at how to improve

indoor air quality and

ensure compliance with

ventilation requirements

in newbuild dwellings.

The updated Approved

Document F regulations,

which came into place

in June 2022, reflect the

growing importance of

healthy living environments, particularly

as homes become increasingly

airtight. Before the 2022 update,

Approved Document F was a single

document that primarily addressed

ventilation in new dwellings. It provided

limited guidance on non-residential

buildings and was supplemented by

the Domestic Ventilation Compliance

Guide, which often led to confusion and

inconsistencies in interpretation.

The revised Approved Document F

comprises two volumes: Volume 1:

dwellings and Volume 2: buildings

other than dwellings. The Domestic

Ventilation Compliance Guide has

also been integrated into the main

document, streamlining the information

and making it more accessible. These

changes reflect a more holistic approach

to ventilation, acknowledging the

interconnected nature of air quality,

energy efficiency and occupant health.

Some of the most significant changes

include:

• Renaming of ventilation methods for

clarity.

• Increased whole dwelling ventilation

rates.

• Modified requirements for

background ventilation.

• Introduction of specific guidance for

existing dwellings.

• Enhanced focus on indoor air quality

and volatile organic compounds

(VOCs).

Indoor air quality

Indoor air quality is crucial for the

health and well-being of occupants.

Poor ventilation can lead to the

accumulation of pollutants, moisture

and allergens, which negatively impacts

health. As building regulations evolve,

building designers need to focus on

ventilation strategies that facilitate fresh

air circulation while reducing energy

consumption. As homes are designed to

be more energy-efficient, achieving this

balance becomes increasingly complex.

The role of mechanical ventilation

Mechanical ventilation systems, such

as Mechanical Ventilation with Heat

Recovery (MVHR) and Mechanical

Extract Ventilation (MEV), play a

crucial role in this balance. MVHR

systems recover heat from outgoing

air and transfer it to incoming fresh air,

significantly reducing energy losses and

heating costs.

MVHR systems, formerly known as

System 4, offer the most comprehensive

approach to whole-house ventilation.

These systems extract stale air from wet

rooms and supply fresh, filtered air to

habitable rooms, while recovering heat

from the extracted air to improve energy

efficiency.

MVHR systems offer excellent control

over indoor air quality and can

provide significant energy savings in

well-insulated homes. They can also

effectively filter incoming air, reducing

allergens and pollutants. Although the

initial outlay for MVHR may be higher

than for MEV systems, these systems

do offer an enhanced level of ventilation

performance, ensuring very good

levels of indoor air quality throughout a

property.

Previously referred to as System 3, MEV

systems provide continuous low-level

extraction from wet rooms, with the

option for boost speeds when required.

Decentralised MEV (d-MEV) operates

through individual fans in each wet room,

offering greater flexibility in installation

and maintenance.

MEV systems have many benefits,

including providing a consistent level

of background ventilation, a reduced

risk of condensation and mould growth

and also lower energy consumption

compared to intermittent extraction. A

lesser amount of background ventilation

is required in habitable spaces to ensure

sufficient cross-ventilation across the

property.

Meeting the challenges

Meeting the requirements of Approved

HEATING, PLUMBING &

VENTILATION

Document F presents several challenges

for specifiers of ventilation systems for

new homes or renovations. However,

working with ventilation specialists

means any obstacles can be overcome.

The increased whole dwelling ventilation

rates specified in the 2022 update

require a more rigorous approach to

system design and specification.

For a one-bedroom property, the

minimum ventilation rate has risen

from 13 litres/sec to 19 litres/sec – a

significant increase that may require

upgrading to more powerful or efficient

systems. As buildings become more

airtight to improve energy efficiency, the

risk of poor indoor air quality increases.

Striking the right balance between

conserving energy and providing

adequate ventilation is crucial. There

are a number of ways to address these

challenges. Firstly, MVHR systems

provide heat recovery which helps to

minimise energy loss, as well as filtered

incoming air. It is also possible to

implement demand-controlled ventilation

to adjust airflow based on occupancy

and humidity levels.

When MVHR is installed, it is essential

to ensure proper sealing of ductwork to

prevent air leakage, which is best done

by using a NICEIC approved ventilation

installer. In addition, on the handover

of a property, it is important to educate

occupants about the importance of not

blocking or disabling ventilation systems.

Highly insulated buildings

In homes with tight building envelopes

designed for optimal energy efficiency,

such as Passivhaus-certified buildings,

natural airflow is usually insufficient

to meet ventilation requirements.

Mechanical ventilation systems ensure

that fresh air is introduced via reduced

background ventilation or incoming

supply ducts for MVHR, while effectively

removing indoor pollutants. In addition,

for buildings situated in areas with high

levels of pollution, such as near busy

roads or industrial sites, mechanical

ventilation is crucial. These systems can

filter incoming air, ensuring a healthy

indoor environment for occupants.

Airflow measurement

Accurate measurement of airflow rates

is essential to verify that the installed

ventilation system meets the required

performance standards. The regulations

specify that:

• Airflow must be measured at each

room terminal.

• Measurement devices must have a

proprietary hood attachment.

• Equipment must have an accuracy

of ±5% and be calibrated within the

past 12 months.

• Results must be recorded on the

commissioning sheet.

For whole-house mechanical ventilation

systems, accurate balancing is crucial

to ensure that the correct airflow is

achieved in each room. This process

involves adjusting dampers and fan

speeds to achieve the desired air

distribution throughout the dwelling.

Housebuilders are required to keep

thorough documentation about

their design decisions and testing

processes. This information is crucial

for demonstrating compliance to local

building control and for providing

homeowners with guidance on

managing their ventilation systems.

Compliance with Approved Document

F means that ongoing maintenance

and monitoring are essential to ensure

continued performance and adherence

to regulations. In addition, with the

increasing recognition of the harmful

impact of Volatile Organic Compounds

within domestic settings, the 2022

update places greater emphasis on

indoor air quality and the control

of VOCs. While specific limits are

provided as guidance rather than

strict requirements, the inclusion of

this information highlights the growing

importance of these factors in building

design and ventilation.

The future of ventilation

As ventilation technology continues to

evolve, systems are likely to see further

advancements. This includes the

integration of smart technologies into

ventilation systems, which is enhancing

efficiency and the user experience.

Demand-controlled ventilation systems

can adjust airflow rates based on realtime

indoor air quality and occupancy

levels. For instance, these systems

can increase ventilation rates when

cooking or showering, ensuring optimal

air quality without unnecessary energy

consumption.

Low carbon

With sustainability remaining a top

priority, the move towards lowcarbon

heating and energy-efficient

ventilation solutions will only intensify.

Housebuilders will need to stay informed

about emerging technologies and

practices that align with sustainability

goals while ensuring compliance with

building regulations. As the industry

moves towards fully implementing

the Future Homes Standard in 2025,

ventilation requirements are likely to

become even more stringent.

By collaborating with ventilation

manufacturers on the design of

systems to meet the latest ventilation

requirements, building designers can

create healthy, comfortable and energyefficient

living spaces that meet both

regulatory requirements and occupant

needs. Effective ventilation system

design can go a long way to address

the potential challenges in new homes,

with the result being improved indoor

air quality, better energy efficiency and

reduced carbon emissions.

the use of brick as the primary façade

material. Until the early 19 th century,

the factory of tool manufacturer Robert

Sorby & Co occupied the site. Its

tools were exported around the world,

including to Australia where its Kangaroo

brand grew strongly and was used until

the 1980s.

The new Kangaroo Works residential

development features a range of highquality

shared facilities and amenities,

including a roof terrace, gym, reception

and co-working spaces. One of the coworking

areas is located on the ground

floor and it was here where Promat

SYSTEMGLAS fire-resistant glazing and

Promat PYROSEC Slimlite fire-rated

doors were specified to provide the

necessary passive fire protection.

Fit-out contractor Whitehead

Commercial Interiors awarded the

internal fire rated glazing project to MD

Glass Partitions, who are experienced

Promat recommended installers. The

brief was to provide two large screens

and two double door sets – all with

minimal framing and maximum glass to

optimise natural light. They also had to

meet a 1B1 safety rating and provide a

high level of acoustic insulation.

The design, including an industrial

look and feel, sought by the interior

designers along with high levels of EI

fire performance concluded that the

Promat SYSTEMGLAS Ferro screens

and Promat Pyrosec SLIMLITE Doors

with ‘Crittall effect’ bars would provide

an effective solution. The SYSTEMGLAS

Ferro and SLIMLITE doors are tested as

complete systems and can be finished in

any RAL colour.

The larger of the two screens measures

approximately 4.2m wide x 2.5m high

and features butt-jointed glass with

plant-on glazing bars applied. Within the

steel frame are Promat SYSTEMGLAS

F1 double glazed units which

encapsulate an intumescent fire-resistant

gel, specified with EI120 fire resistance

(120 minutes integrity and insulation

protection) and acoustic insulation with a

sound reduction level of 47dB (Rw). The

second screen is a similar construction

and configuration with dimensions of

approximately 3.6m x 2.5m, an EI60

level of fire protection and 45dB (Rw)

sound reduction.

Two double door-sets were created

using the Promat SLIMLITE steel framed

glass door system. The 2250mm wide x

2460mm high door-sets were specified

to provide EI60 fire resistance and

featured slim side panels at either side

to keep within tested evidence, as well

as full height back to back handles. The

glass used in the door-sets was Pyrosec

EI60 which combines fire resistance with

a 40dB (Rw) sound reduction rating.

Chris Hays, Project Coordinator at MD

Glass Partitions, says: “It was a pleasure

working with Promat and Whitehead

Commercial Interiors to deliver this

exciting project and I look forward to

being involved in future similar fire rated

glazing projects. The SYSTEMGLAS

Ferro and Pyrosec SLIMLITE door

systems provided solutions that

balanced aesthetics and performance,

with the added benefit of Promat’s

technical support throughout the design,

manufacture and installation stages.”

FIRE REVEALS NEED FOR

AUTOMATIC SPRINKLERS

SECURITY & FIRE

PROTECTION

Iain Cox, Chair of Business

Sprinkler Alliance,

discusses how early fire

suppression methods can

help fire services bring

incidents under control.

The fire that tore through a

6,000m 2 mixed-use building on

the Brucefield Industrial Estate in

Livingston in December has highlighted

the huge challenge faced by firefighters

when fire breaks out.

The extensive fire required nine

appliances, two aerial ladder platforms,

two pumping appliances, and a bulk

water carrier from the Scottish Fire and

Rescue Service (SFRS) to bring it under

control. While thankfully there were no

injuries, the industrial unit was destroyed,

impacting several businesses.

Tom Roche, Secretary of the Business

Sprinkler Alliance (BSA), says: “What

caught my attention was the sheer

destruction of what was a simple

industrial building. It underscores

how quickly these fires escalate when

buildings are not protected by automatic

sprinkler systems.”

Roche emphasised the critical

importance of early fire suppression,

explaining that while the average

response time to a primary fire in the UK

is eight minutes and 50 seconds, the

actual development of a fire can begin

long before the first appliance arrives.

Delays in discovering the fire, assessing

its nature and notifying the fire service

can allow the fire to grow unchecked.

Upon arrival, firefighters must evaluate

access, water supplies, and the safety of

the scene – all while the blaze continues

to intensify.

In stark contrast, when fire broke out

at a Winsford Packaging Factory in

January 2022, the fire was contained

by the premises’ sprinklers, preventing

significant damage and allowing the

situation to be managed quickly.

Similarly, a fire at a Lutterworth

Warehouse in March 2022 that started

in storage racks was suppressed

by sprinklers, enabling firefighters to

extinguish it with minimal disruption.

The BSA is advocating for the wider

adoption of sprinkler systems across

the UK’s built environment, including

industrial and commercial buildings.

Beyond the immediate destruction of

property and business interruption,

these incidents disrupt local economies,

jeopardise jobs, and place enormous

pressure on emergency services.

INTUMESCENT COATING SYSTEMS

FOR FIRE PROTECTION: WHAT YOU

NEED TO KNOW

Intumescent coating

systems, also known as

reactive coating systems,

can form an integral part

of a building’s fire safety

and fire protection

strategy. But there are

many considerations,

especially when it comes

to how they are tested and

certified. Here Dmitry

Podolski, Technical

Manager at Element

Materials Technology,

explains more.

Among various steelwork

protection options,

intumescent coating

systems are one of the

most commonly used

and globally accepted measures. In

the built environment, intumescent

coating systems typically consist of thin

films applied in layers over steelwork,

including a primer, intumescent paint,

and a topcoat. The intumescent paint

reacts to fire by expanding many times

its original size, forming a larger thermal

protection barrier around the steel.

Intumescent coating

systems offer one of the

most efficient methods

of protection for

structural steel

elements and can be

applied and installed

with relative ease.

Intumescent coating systems offer

one of the most efficient methods of

protection for structural steel elements

and can be applied and installed with

relative ease. These coatings can also

be used on steelwork of various shapes

and sizes, making them a versatile

solution for many projects. Incorporating

intumescent coating systems into

a building’s passive fire protection

specification is a crucial step in ensuring

fire safety and business continuity.

However, correct testing and accurate

specification are vital when bringing

these products to market and for the

coating systems to perform effectively in

the event of a fire.

Testing process

There are several considerations for

manufacturers during the testing

process. First and foremost, testing

should be undertaken by an independent

laboratory holding accreditation for the

relevant test by a National Accreditation

Body, eg, UKAS & BELAC.

Intumescent coating systems are

typically applied to structural steel

sections at the test houses. However,

if manufacturers choose to apply the

coating off-site and then send the test

specimen to the test house for fire

testing, it is good practice to include a

repair kit with the test specimen. This

ensures any damage to the intumescent

coating system during transit can be

repaired, maintaining the accuracy and

performance of the results.

It is also important to note that

environmental conditions can change

drastically when shipping intumescent

coating system components or test

specimens internationally, potentially

affecting product characteristics

and the end performance. However,

this risk can be mitigated by making

appropriate arrangements, such

as using environmentally controlled

shipping containers. Accuracy in

testing is of utmost importance. That’s

why at Warringtonfire, part of Element

Materials Technology, a clearly defined

and rigorous process is adhered to.

When all steel sections intended for

the intumescent coating system arrive

at the laboratory, they are measured,

recorded and verified against relevant

specifications before proceeding to

fabrication.

After fabrication, the sections are

typically cleaned by shotblasting,

following the manufacturer’s instructions,

to remove rust and create a profile

64

64_SB0325.indd 4 27/02/2025 16:42


that aids primer layer application. The

primer is then applied in a controlled

environment within a short window

after shot blasting to prevent rusting or

contamination of the steel surface.

After priming, thermocouples are applied

to each section as per the required

specification. These thermocouples are

used to record the core temperature

of the steel during the fire test. The

intumescent paint is then applied to the

sections. Application duration depends

on the required overall thickness –

known as dry film thickness (DFT).

The greater the DFT, the longer the

application process will take. Once

the required DFT is achieved, the

intumescent paint will need additional

time to cure. The curing time will depend

not only on the DFT but also on the

specific properties of the product.

When additional components, such as

reinforcement mesh and/or topcoat,

are part of the intumescent coating

system, they are applied individually

in strict accordance with the relevant

specification.

After ensuring the intumescent coating

system is ready for testing, the sections

are mounted on the furnace cover

slabs a day or two before the fire test,

preparing them for loading into the

furnace. A furnace section layout map is

used to identify each section’s location.

Each section is equipped with several

thermocouples connected to the furnace

logger computer, which monitors and

displays the steel core temperature at

that location.

During the fire test, each section is

monitored via the thermal data (displayed

on a screen) and observed through

viewing portals inside the furnace. Once

the required temperatures are achieved,

the test is complete.

Shortly after the fire test, the raw data

is sent to the client. The responsible

laboratory personnel will then format the

data ready to be entered into the fire

test report. The final stage of the testing

process is to produce the fire test report,

which is peer-reviewed by a competent

person, before being finalised.

Where can intumescent coating

systems be applied?

Intumescent coating systems can

be applied to steelwork on-site or

off-site. They are a great solution for

various shapes and sizes of steel and

can also provide an attractive finish if

the steelwork is exposed as part of a

building’s design.

Fire resistance requirements can

vary, but most intumescent coating

systems are designed to withstand fire

for increments of 30, 60, 90, 120, or

even 180 minutes, depending on the

specification, building design, and the

structural requirements of the steelwork.

Selecting the correct intumescent

coating system for a project is the first

step in ensuring fire safety, followed

closely by making sure that precise and

relevant testing has been conducted.

Confidentiality with testing

Rigorous testing ensures manufacturers

are up-to-date and operating in

compliance with industry standards.

As is common with globally accepted

products, there are several relevant

tests and standards for fire testing

intumescent coatings, but the most

common are currently BS 476 parts

20, 21 and EN 13381-8. Engaging with

a reputable fire testing provider, such

as Warringtonfire, will help determine

the most appropriate testing for the

product. Manufacturers typically work

very closely with the testing provider and

assessment/certification body from start

to finish to ensure the product’s fitness

for purpose, as well as a high level of

accuracy and detail in the testing.

Warringtonfire’s Birchwood Park

laboratory, which opened its doors in

January 2025, features seven dedicated,

confidential spray booths, with the

potential for a further two to be added

in 2026. Testing is performed in a

temperature-controlled environment

to ensure accurate results and proper

coating application. Additionally,

technology such as an autofed shot

blast booth with an abrasive recovery

system and modern blast machine

enhances testing efficiency.

Due to the nature of these firesafety

products, it is critical to seek

the best possible advice from the

beginning. A comprehensive end-toend

solution, including independent

fire testing, technical assessment and

fire certification, can provide a globally

respected mark of quality assurance.

This approach helps ensure a

competitive advantage by selecting

the best possible testing scope, and

by providing support and advice

throughout. When lives are at stake, it is

crucial to take all necessary precautions

to ensure consistent, high-quality

practices are upheld across the industry.

NAVIGATING GATEWAY 2

Quelfire held a panel discussion at London Build titled

‘Navigating Gateway 2 Submissions – Experiences,

Challenges, and Insights’. The session brought industry

professionals together to share their knowledge and

experiences from Willmott Dixon’s first complete gateway

submission. Specify & Build reports.

When The Building Safety Act

(BSA) came into force it set the

foundation for building safety

in the construction sector. Establishing

the concept of high-risk buildings

(HRBs), it created a new system of

Gateways to control their planning,

design, construction and maintenance.

It also placed new responsibilities on

the accountable person, dutyholders,

client, and the principal contractor and

designer, requiring those working on

construction projects to demonstrate

that they are competent. Ultimately, the

Gateway regime controls the flow and

progress of high-risk buildings.

Competency is made up of four

components: skills, knowledge,

experience, and behaviours. Craig Wells

commented that the behaviour aspect is

challenging to measure but is one of the

most important: an individual can have

the skills, knowledge and experience,

but without the willingness to do the right

thing, it all amounts to nothing.

Tom Hughes added that competency

allows design practices to interrogate

their internal processes and procedures,

ensuring they can de-risk and hit

compliance targets before speaking to

building control.

James Felstead advised the audience

to get ahead of the curve. If you’re likely

to work on a HRB that will go through

the Gateway regime, start reviewing

competency now. Much of the process

involves demonstrating and documenting

processes you may already be doing.

The BSA has also been the catalyst for

cultural change, especially regarding

attitudes towards fire safety: ‘design,

then build’. Jeremy Ockenden said the

current attitude of design teams is that

they must collaborate and demonstrate

compliance with building regulations.

He said: “We have to be absolutely rock

solid.”

What challenges lie ahead?

One main challenge stressed by Graeme

Whitty was the lack of guidance on how

much information the regulator required.

For example, Willmott Dixon submitted

over 900 documents for its first Gateway

2 submission for its ‘The Stage’ project.

The panellists included:

• Craig Wells, Sales Director

– Quelfire

• Graeme Whitty, National

Product Director, Willmott

Dixon Construction

• James Felstead, Director –

Child Graddon Lewis

• Jeremy Ockenden,

Technical Director – Affinity

Fire Engineering

• Tom Hughes, Principal

Building Safety Consultant

– Safer Sphere

This level of information also includes

the procurement of products. Hughes

explained this may cause issues later if

the chosen products are discontinued,

causing uncertainty. Whitty added

that the regulator must approve any

slight change to the submission before

implementation, so circumstances like

discontinued products could cause extra

costs and delays. While this will inevitably

be a learning curve, Hughes highlighted

that by adopting the ‘design then build’

model, projects will avoid potential risks

due to having more information to work

with at the tendering stage.

Ockenden added that before the BSA,

there was a tendency to think ‘we’ll

sort out the management at the point

of occupation’. But this is now being

brought earlier into the process because

the regulator wants full consideration.

This means collaboration is not just

between the design team but also

involves the client and person operating

the building.
