NEW REGULATION COMPLIANCE THREATENS HOUSING TARGETS

Ministers have met this week with the construction industry to hold talks over controversial post-Brexit safety testing rules that the sector argues could delay the construction of 150,00 new homes next year, E&T can reveal.

As well as derailing government house-building targets, the construction industry has warned that the rules could impact the UK’s decarbonisation efforts and exacerbate the cost-of-living crisis.

Under the UK’s new regulatory goods regime, manufacturers currently have until 1 January 2023 to obtain a UKCA marking on a huge range of products which will replace the EU CE marking. The government says the move is an opportunity “to make our regulations work in the best interests of UK consumers and businesses”.

However, the construction industry says the deadline represents “a fast-approaching cliff edge” as there is not enough testing capacity in the UK to ensure certain crucial building products are certified.

The CE mark demonstrates that products comply with health and safety and environmental protection legislation. It has been a minimum requirement for manufacturers to place on their products in the EU market since 1993.

CE testing is currently undertaken across a network of European testing and certification bodies but under the new system, the UK will not recognise these certificates. This means that, in some cases, manufacturers will need to have their products retested even though the technical requirements and standards that need to be met are largely the same for UKCA as they were for the CE mark.

Last week, Brexit minister Jacob Rees-Mogg hinted that the UKCA mark could be dropped, arguing that “there is no point in us repeating things that other organisations and countries do to a perfectly competent standard”. But he was promptly slapped down by No 10, which confirmed the UKCA mark would be introduced on 1 January next year, as planned.

While many construction products can be brought to market with a ‘self-declaration’ of conformity to demonstrate compliance with the regulations, several crucial construction products including radiators, glass, passive fire protection, glues and sealants will have to be completely retested before they can be sold in the UK.

The Construction Leadership Council (CLC), a joint industry-government body, has estimated that the inability to certify radiators in the UK “could delay the construction of over 150,000 homes in a single year” while also delaying “the switch to low-carbon heating”. To put this in context, the government has a target to build 300,000 new homes a year.

In addition, the government has pledged to install 600,000 heat pumps a year by 2028. Heat pumps require larger radiators as they run at lower temperatures than conventional gas-powered boilers, although heat pumps can also be used with underfloor heating systems.

Tom Garrigan, technical director of BSRIA, which is currently the only UK-approved body to test radiators for the UKCA mark, noted that there are eight EU-notified bodies that test radiators for CE-marking purposes in Europe.

“On the assumption their individual annual throughput is similar to that of the single UK-approved body, there is estimated to be an enormous 64 years’ worth of retesting required,” he added.

Carrigan said this was an “impossible target to achieve” by 31 December 2022.

As it stands, manufacturers and distributors of radiators that have not had their products retested would legally have to remove products that had not been tested from the market in Great Britain after this date.

“This is clearly an unintended consequence, however this may lead to a deregulation of product conformity, limit product availability, and a backlog of testing could stifle innovation as new product designs will be required to enable low-carbon technologies to operate efficiently,” said Carrigan.

 

The issue is not just confined to radiators.

The Construction Products Association (CPA) says other products that may not be tested before the deadline due to “a lack of capacity, capability or ambiguity in the legal requirements include: windows and doors, insulation products, synthetic renders, adhesives and sealants, coated and laminated glass, timber products, electric cables, cement admixtures and some critical fire-safety and building-system products”.

The CLC told E&T that it had had a “productive meeting” with the construction minister Lee Rowley on Wednesday and understood that “further developments are likely in the near future”. The Department for Business, Energy and Industrial Strategy said it was “working on solutions to issues around construction products testing capacity and supporting industry to prepare for UKCA adoption”. But it is not clear what type of solution may be forthcoming.

The government has already extended the deadline for UKCA by a year to 1 January 2023 but the CPA says this will still not leave enough time for testing.

Peter Caplehorn, the CPA’s chief executive, told E&T: “At the moment, industry’s hands are tied. Post-Brexit, the CA regime limits us to having access to only 70 certification and testing organisations in the UK, where previously we had access to over 700 across the EU.

“We would agree with the recent reported comment by Jacob Rees-Mogg; in the case of the great majority of construction products there is simply no point to the new CA regime. This process makes no difference to the quality, safety or robustness of a product.

“It just adds significant costs to retest, re-certify and rebrand the same product to place it on the UK market.”

There are also concerns that these extra costs will be passed on to consumers, who are already facing unprecedented rises in energy bills this year.

Garrigan said that “an option to avoid the cliff-edge at the end of the calendar year” would be for the government to recognise products such as radiators that are already compliant under the CE system as valid in the UK.

However, this could prove difficult politically for the government as it would mean UK goods would be aligned with EU rules that the UK has no control over, defeating the original rationale behind Brexit.

HIGH PERFORMANCE, FUEL SAVING EFFICIENCY FOR LIMITLESS HOT WATER

creating a healthier way of living

DON’T GO ‘LIKE for LIKE’ TRADE UP

TO HIGH PERFORMANCE, FUEL SAVING EFFICIENCY FOR LIMITLESS HOT WATER

TEMPERATURE ACCURATE ON DEMAND READILY AVAILABLE NOW

Hydrogen blends-ready Rinnai continuous flow hot water delivery units&systems

analysis shows 20% (min.) carbon emissions reduction compared to heated storage systems

 

 

When a stored water system or unit comes to the end of its working life it is assumed that replacing ‘like for like’ is the best option. But, says Pete Seddon for Rinnai, ‘If we look at the ‘like for like’, out with the old one and in with the same model stored water heater – there is actually a huge and costly amount of work involved. Changing the same old for the same new does not mean it is better. Most plant rooms are limited in space which would require the old equipment being removed before the ‘like for like’ appliances can be installed.

Easy access and continuous, limitless flows of hot water are critical components of building services for all applications in all sites adds Mr Seddon.

He says, “Continuous flow technology in hot water delivery provides constant flows of temperature specific and controlled delivery end-product, which are hydrogen blends and BioLPG ready. They are also a one-man lift requiring no lifting gear.

‘Not only that, but if the appliance being replaced was non-condensing and the new appliance was condensing, then the flue would most likely require changing as well as the provision to discharge condensate. Plant rooms are very rarely designed to remove equipment. This requirement to remove equipment before new is installed would have a major impact – and it takes so much time,’ adds Pete Seddon.

‘The hot water system would have to be completely shut down to allow such major works to take place and all sites, especially healthcare ones, cannot simply allow this to happen.

Due to the size and weight of these appliances it can make life exceedingly difficult for installers. They are usually manufactured with Enamel Lined (Glass Lined) Mild Steel which can make it extremely heavy but also very fragile. It would require multiple personnel to manoeuvre these out and in, even specialist lifting equipment and for plant rooms high up cranes would be required. All of this will add a lot of time and cost to the overall installation. Not only that, but if specialist lift equipment and cranes are required you are going to need suitably trained personnel as well as permits.

Says Pete Seddon, “So, what can continuous flow solutions offer that can make this entire process a lot easier? Well, we will start with their size and weight. This type of technology is 30kg. That is a one-man lift. Two sizes are available – 47kW and 58kW. This would equate to a large volume of hot water for such a physically small appliance. (774 and 954 litres per hour at a 50-degree rise).

‘The other benefit is the ability to cascade these appliances so when more hot water is required you would simply add more continuous flow water heaters. This would mean that just a single installer could create a system that would produce vast amounts of temperature accurate hot water. Whilst also creating built-in redundancy – this means that if one unit needs to be shut down the complete site still has ready access to hot water.

“Also possible is a ‘plug and play’ cascade sequencing control system that will automatically control how many appliances are running at any one time, all the installers would have to do is plug it in and select the primary water heater. Continuous flow can easily cope with any size of healthcare site. Simple as that,’ adds Mr Seddon.

With a continuous flow system there are also externally sited units where there is just no space in a plant room. These external hot water heaters are fully weather protected with and hold IPX5D rating. Installations also come with frost protection down to -20°C and will keep the appliance protected so long as the mains power supply is left switched on.

When measured in economic performance, continuous flow water heaters are half the yearly costs on a Peak Period of 3 hours per day at 960 I/h that a combustion unit would accumulate.

A typical water storage-based installation will cost £5,662.13 per year, where in comparison a Rinnai continuous flow water system will cost £2,736.02.

Rinnai’s complete range of hot water heating units are available for next day delivery on orders placed before the previous mid-day.

A NEW BRITISH INVENTION

The Portascanner® AIRTIGHT 520: Complementing Essential Existing Technology for Airtightness Testing in the Built Environment

A new British invention, following the co-location of Coltraco Ultrasonics’ Physicists and Scientists at Durham University, a globally outstanding centre of teaching and research excellence, the handheld Portascanner® AIRTIGHT 520 is a completely unique technology able to compute air flow and air permeability, quantifying leak sites to complement an airtightness test. Designed during COVID-19 with support from UK Government COVID-19 Emergency Technology Funding and available for exporting globally now, the Portascanner® AIRTIGHT 520 builds on Coltraco’s long history in watertight integrity monitoring for the Royal Navy to deliver the Safeship™ at sea, applying our advanced understanding of fluid dynamics at sea to air flow dynamics to deliver the Safesite™ on land.

The unique ability to detect, locate and quantify air leaks, non-disruptively and without the need for any room pressurisation, in a complementary manner to existing Door Fan and Pulse Airtightness Testing, will enable users of the Portascanner® AIRTIGHT 520 to make sharper decisions, verify technical specifications, and reveal possible defects if design standards have not been met rapidly and reliably.

The Importance of Building Ventilation: Changing Standards in the Built Environment
Professor Catherine Noakes OBE, who sits on the UK Scientific Advisory Group for Emergencies (SAGE) states that “if we do invest as a nation [in ventilation], there’s a potential big win,” with the “long-term payback [of] improved health and productivity, and lower energy use.”
COVID-19 is essentially an indoor air crisis. Whilst vaccinations are a crucially important tactical response, they must be complemented by longer term strategies. To ensure Human Air Hygiene, and safeguard that basic human right, a continuous and assured access to pure, fresh air, every public building must have a Ventilation Strategy.
In its most basic form, the challenge of building ventilation centres around increasing the number of air changes per hour. However, the integrity of air filtration, and or air purification, can only reasonably be assured if all unwanted air infiltration through gaps, is sealed. Air flow measurement devices, such as the Portascanner® AIRTIGHT 520, that allow for frequent and regular detection, location and quantification of unwanted air leaks must therefore be integrated alongside existing airtightness testing equipment, to ensure the success of building ventilation strategies.
In addition to Human Air Hygiene, Fire Suppression, Thermal Comfort, Acoustic Insulation, and Insect and Pest Control are all integral aspects of the Built Environment which require a certain level of airtightness to be maintained, either to deliver the minimum number of air changes per hour, restrict the supply of oxygen to extinguish a fire, or lower energy consumption and waste.
Indeed, in a post-COP26 global environment, addressing the effects of climate change and making buildings more energy efficient and environmentally responsible is driving the construction industry towards “Build Tight Ventilate Right.” Buildings are a significant producer of carbon emissions, accountable for 35% of total energy consumption.
Testing for air leaks and simultaneously testing for watertightness with the Portascanner® AIRTIGHT 520, as water ingress seriously damages buildings and destroys electrical equipment, will improve build qualities, and reduce the costs of operating and maintaining the Built Environment.

The Portascanner® AIRTIGHT 520: Unique Technology to complement Existing Airtightness Testing
During Coltraco Ultrasonics’ long history in watertight integrity monitoring for the Royal Navy they learned that it was one thing to be able to identify large and microscopic leak sites, but that it was quite another to precisely locate and quantify the leak site through the structure concerned to determine the water flow rate. These are the crucial pieces of information required to assess the damage control risk overall in a ship’s watertight compartment, watertight door or watertight Multiple Cable Transit Area between bulkheads.
The Portascanner® AIRTIGHT 520 takes Coltraco Ultrasonics’ understanding of fluid dynamics at sea and applies it to air flow dynamics on land. They take the best ultrasonic technology in Coltraco’s hardware to identify leak sites with a microscopic level of accuracy and apply computer science to measure and quantify the leak-site by the Portascanner® AIRTIGHT 520’s algorithm, which also generates a value for the air flow rate through that leak and the building’s overall air permeability.
The ability to record and analyse these 4 factors makes the Portascanner® AIRTIGHT 520, a British lightweight, hand-held, and portable analytical instrument, a unique technology globally. The Portascanner® AIRTIGHT 520 has been invented to complement existing airtightness testing, typically achieved using a Door Fan Test or a Pulse Test, that is essential for measuring the integrity of the Built Environment.

Integrate Dynamically with Essential Existing Technologies to be Better-Faster-Cheaper: Testing the Portascanner® AIRTIGHT 520 at The Airtightness Testing and Measurement Association’s (ATTMA’s) Building Performance Hub
In January 2022, Coltraco Ultrasonics’ Daniel Dobrowolski (Senior Physicist) and Bernard Hornung (Head of Built Environment) joined Paul Jennings (Airtightness Specialist) and Dr Bill Bordass OBE (Building Scientist) to test the Portascanner® AIRTIGHT 520 in a full-sized house. Testing followed a Pulse Test and a Door Fan Blower Test, both of which the Portascanner® AIRTIGHT 520 is designed to complement.

The Portascanner® AIRTIGHT 520 performed outstandingly, being able to identify and quantify leaks that had been found with traditional basic methods of leak detection such as thermal cameras, smoke pencils and anemometers, but most importantly finding leaks that could not be found with any alternative method. A significant number of leaks were identified in window and door seals.

The Portascanner® AIRTIGHT 520 allows the ultrasonic quantification of leak sites in a depressurised environment, which has never been achieved before. Door Fan Testing or Pulse Testing can then be conducted at an appropriate moment, once detected leakage points have been identified and repaired. Uniquely, during these tests, the Portascanner® AIRTIGHT 520 allows the location and measurement of air leaks, facilitating remedial action that is precise, immediate, and often low-cost.

Furthermore, Buildings can be surveyed with a Portascanner® AIRTIGHT 520 before an air tightness test so that they have a better chance of passing and, if a building fails an airtightness test, the diagnosis as to why it has failed could include locating and quantifying air leaks with the Portascanner®.

These capabilities of the Portascanner® AIRTIGHT 520 are even more important when one situates the device within the increased world-wide emphasis on airtightness in the built environment as a result of the dual pressures of COVID-19 and climate change. In the UK, higher standards on airtightness in the Built Environment are being encouraged by institutions such as the Passivhaus Trust, which forms a part of the global Passivhaus movement, and is the UK affiliate of the International Passive House Association.

Passivhaus builds are approximately ten times more airtight than the standard required of new-build domestic dwellings in the UK, meaning special attention must be paid to identify potential leakage areas in the building fabric and offsite-manufactured components during the final stages of construction. There are about 65,000 buildings worldwide which have achieved Passivhaus standards of comfort, health, and low energy consumption, with many more in the planning process.

Being able to use ultrasound to detect, locate, and quantify air leaks, eliminates the need for pressurisation, negative or positive. Therefore, the Portascanner® AIRTIGHT 520 can test building components when they are manufactured, such as windows and doors, which is where most leaks manifest themselves, with the aim to eliminate leaks before installation. During the execution of a build programme, or in the case of offsite construction, during the assembly of building components, building control aimed at assuring a better build quality should include the frequent and periodic use of the Portascanner® AIRTIGHT 520.

Coltraco Ultrasonics’ technologies provide their users with the unprecedented visibility necessary to make sharp decisions and understand opaque issues. Integrating the Portascanner® AIRTIGHT 520 with essential existing Door Fan and Pulse airtightness testing will improve build quality, and reduce the costs of operating and maintaining the Built Environment, by improving Human Air Hygiene, Fire Suppression, Acoustic Insultation, Thermal Comfort, and decreasing water ingress and absenteeism.

TURNING DOWN THE HEAT

Turning down the heat:

Futureproofing the homes of tomorrow

Authored by Mark Dowdeswell, Senior Category Manager – Domestic, at Uponor

 

New homes will have to produce around 30% less carbon emissions as part of a major update to the Building Regulations this year. Under Part L1A, there will be a maximum flow temperature requirement of 55°C for new and replacement heating systems, meaning that more low energy heating systems must be used in today’s modular builds.

Underfloor heating systems (UFH) have a larger area heat emitter than traditional radiators, meaning they require a lower heat input in order to heat a room effectively. This allows them to work efficiently alongside renewable heating technologies, such as air source heat pumps (ASHP), which help to reduce a home’s operational carbon footprint.

 

With technology constantly advancing, both ASHPs and UFH now lend themselves perfectly to modular builds with limited space and high-quality design demands. Innovative low profile UFH systems, such as Uponor’s Minitec which stands at just 15mm build height, enable design teams to optimise available space, giving maximum design freedom. To ensure consistent quality of UFH installations in modular assemblies, Uponor also works closely with its partners to provide design support, continuous training and installation reviews, whilst simultaneously providing the largest product range of radiant heating and cooling systems of any manufacturer from under one roof, meaning that design teams do not have to compromise on their aspirations.

This vast product range also enables contractors, architects and specifiers to work alongside one manufacturer, rather than multiple suppliers, allowing them to rest assured that the systems used will not only meet building regulations and hit new performance goals, but that they will be fully-warranted and long-lasting, meaning that the homes built for today, will perform well tomorrow, too.

RINNAI – WE ALL WIN WITH NETZERO

 common sense, calm and commitment

 

Cp and hot water industry and this can be supported via gathered scientific data applied to finding solutions that allow for least harm and disruption to current standards of living and comfort.

The manufacturing sector of the heating and hot water industry has a responsibility in playing a leading role in the reduction and eventual removal of harmful emissions. For UK decarbonisation targets to be met, working practises that rely on fossil fuels have to be changed and transparent assessments of product impact and efficiency should be common currency. To enact the transition to greener energy there is a pressing need for unity of purpose across multiple industry sectors.

 

 

Rinnai Managing Director Tony Gittings says: “Fact, logic and reason must be employed to achieve the best outcome for all of us. We need decarbonisation, we need NetZero, and we need it as soon as possible but in such a way that is pragmatic in terms of catering to the existing populations and markets.”    

“To further encourage decarbonisation the heating industry must look past just simple financial motivation. No one single product alone is presently capable of delivering NetZero, so rather than fracture into competing groups, the heating & hot water sector will benefit from a platform of cross-communication and information sharing that can be relayed to positively assist the UK end-user and customer.

“We need to look at this from the consumers’ viewpoint. We need to be putting accurate information in the public arena. At the moment there are a lot of interested bodies and companies showing understandable self-interest in wanting to know they have a future in the marketplace.

“In our sector we have manufacturers of similar or like-for-like products which are looking to what will replace natural gas as the fuel of mass consumption and how that will affect them. We also have the pragmatic logic of trying to find affordable fuels for the mass market. Alternatives on their own are simply not an answer. We also need to look at the range of innovations and developments such as Hydrogen and BioLPG that will come on stream.

“Yes, individual products have a place. But what would be the NetZero answer, as an example, to a commercial or industrial unit or site that has the added complications of needing Legionella prevention regimes and constant high temperature hot water in large volumes. How would electrification and heat pumps, for example, be attractive in terms of capital, installation and ongoing operational costs and performance?

“Everything has a role to play and everything non-carbon can have a future. And a collective, equable effort will give us the result we all want, the result we must have, if we are to have a sustained quality of life.

“We are a business based on engineering excellence and are employing technological creativity to achieve the targets. It will mean, in the UK, that we begin to offer a wider range of products under the H3 umbrella of Hydrogen, Heat Pumps and Hybrid Systems to enable our customers to achieve their own carbon reductions and eventual neutrality.”

 

Rinnai are also now offering a free “Carbon Cost Comparison” that can be found by following this LINK .   The Rinnai Carbon Cost Comparison Form offers a free appraisal of a site’s current hot water delivery system, along with recommendations for reducing the carbon load.

TRIPLE CHALLENGE FOR NEW MD

It’s a triple crown for Steve Marshall who has not only taken over as Managing Director of Strand Hardware, but also its two sister companies – Strand Technologies and AliMet Fabrications.

The industry stalwart has taken the helm of the three Midlands companies following a 24-year career at GEZE UK where, for the past two years he served as Operations Director, following roles in the service and commercial teams.

However, his new challenge has taken him full circle – he began his career as an estimator for an aluminium door and window fabrication company (James Gibbons) before moving into the world of automatics (Newman Tonks followed by Horton Automatics).

Steve’s appointment is a significant step change for Strand Hardware and demonstrates a resounding belief in his abilities. It will be the first time that the company has seen day-to-day operations managed by someone outside the family-run firm. Strand was founded by Jonathan Franks in 1991 and his daughter, Catherine, took on the role of Managing Director in 2005. She will continue to help steer the ship in her new role as Chair of Strand Hardware.

Said Steve: “It is such an exciting challenge. They are three fairly different companies which at the same time complement each other. My work at GEZE UK has given me a background in door hardware, albeit that Strand Hardware has a different range of specialist products, but I know a lot of people in the industry that are customers of Strand already.

“GEZE also distributed iContact which is a pivotal product within the Strand Technologies range.   Although a relatively new company, Strand Technologies is going from strength to strength and diversifying into many new markets outside the door industry. I began my career with a door and window fabrications company, so AliMet’s business is not unknown to me either. All three are really, really exciting, and I’m looking forward to working with the teams, helping them develop and achieve further growth.”

He says he intends to spend his first 100 days ‘learning and planning’ – getting to know the teams, existing customers, market segments and identify opportunities for growth, development and diversification.

Steve will be supported at Strand Hardware by Sales Director Craig Fox and General Manager Jo Wallis in managing the day-to-day business operations.

Catherine Franks is to focus on special projects, strategy and investments. She said she felt certain that Strand Hardware and its sister companies were in “a safe pair of hands”.

“I would not move aside, if it were not for the certainty that Steve is absolutely the right person for the job. Managing three companies is not easy, each has its own unique demands but Steve has huge amounts of experience working within complex working environments and to time-sensitive deadlines. I feel confident that he will be able to support all three companies and help them grow.”

SterlingOSB Zero a great choice

The practical benefits that make SterlingOSB Zero a great choice for the UK construction industry

 

With an ever-increasing checklist of requirements, UK builders have very exacting standards when sourcing the right materials for their project. Choosing panel products that satisfy building standards, have sound environmental credentials and are quick and easy to use when battling all that the Great British weather has to offer, it’s no wonder West Fraser’s (formerly known as Norbord) SterlingOSB Zero range is one of the most popular in the construction industry.

West Fraser’s OSB portfolio comprises of SterlingOSB Zero OSB3, SterlingOSB Zero Tongue and Groove, and SterlingOSB Zero StrongFix. They are variants of the precision-engineered OSB3 board; BBA-approved and designed for humid conditions, the board contains zero added formaldehyde (ZAF) and is unique in the market by being the only ZAF OSB manufactured in the UK.  Produced in Scotland from forest thinnings taken from sustainably managed forests, the board is certified according to the guidelines of the FSC or PEFC.

Among its multiple uses, SterlingOSB Zero is ideal for timber frame construction. The boards are designed to speed up the build process and are available in a wide range, thicknesses and sheet sizes. For structural use in dry or humid load bearing situations, SterlingOSB Zero OSB3 is the board of choice. When undertaking dry lining, SterlingOSB Zero StrongFix quickly provides secure anchorage areas.

Flooring and roofing applications are served by SterlingOSB Zero OSB3 and SterlingOSB Zero Tongue & Groove. Panels are easy to saw, drill, nail or plane. SterlingOSB Zero’s smooth surface gives improved adhesion qualities for all flat roofing applications with no sanding required, even for GRP finishes.

In building sites all over the UK (and other rainy, snowy or generally mucky climates), the art of getting buildings wind and watertight quickly is an important one that the builder needs to get right! Choosing a quick, easy to install, reliable and versatile roofing system is, therefore, vital. High quality roof decking or pitched roof sarking is an essential component and Oriented Strand Board (OSB) is now the preferred option for many today. And winning the game with outstanding attributes is West Fraser’s SterlingOSB Zero OSB3 or SterlingOSB Zero T&G.

Ideal for structural use in load bearing dry or humid conditions, SterlingOSB Zero OSB3 offers great value and durability. Stronger than most softwood ply, thanks to its makeup of multiple layers of real wood strands pressed together, it is designed to withstand the toughest of conditions. Working with the boards is trouble free as they are uniform in quality with no knots, voids or delamination issues. Helping to cut waste, a range of panel sizes and thicknesses is available to suit all needs.

The boards are square edged so butt together easily and cleanly. Panels are cut and installed on a roof using conventional roofing equipment and are easy to saw, drill, nail or plane. Nails can be driven as close as 8mm from the panel edge without causing splitting. SterlingOSB Zero’s smooth surface gives improved adhesion qualities for all flat roofing applications and no sanding is required, even for GRP finishes.

With all the advantages of the Sterling OSB Zero range, SterlingOSB Zero T&G is specifically designed for flat roofing and is BBA approved and fully compliant to BS 6229:2003. The panels are consistent and machined to exact tolerances. Reliable fixings are easily achieved across the board using 3mm diameter ring-shank nails or 50mm long screws at 100mm centers across the supporting joists.

The inherent strength of SterlingOSB Zero makes it the natural choice for site hoardings and for boarding up windows and doors of vacant properties. Hoardings formed using SterlingOSB Zero may be finished with most popular surface treatments, allowing marketing messages and designs to be displayed to create a smart site perimeter.

Along with its many practical attributes, the Sterling OSB Zero range has strong environmental credentials. All West Fraser panel products produced in the UK are net carbon negative and manufactured in mills that have obtained the coveted environmental ISO 14001 accreditation. Responsibly sourced, the panels are FSC certified and created from locally grown timber, cutting embodied carbon from transportation. Sterling OSB Zero is also the first OSB product to be made in the UK with zero added formaldehyde, ensuring an even ‘greener’ board that meets all standards with ease.
