Sika Sarnafil launches BRE certified thermal details

In a move to help specifiers make buildings more sustainable, Sika Sarnafil is proud to announce the launch of its BRE Certified Thermal Details, available to download via its online Sustainability Hub and from the Certified Thermal Details and Products scheme website.

The Certified Thermal Details and Products scheme, run by world-leading building science centre BRE, gives thermal junction details an independent third party assessment, assuring users of the ‘as designed’ thermal performance. Sika Sarnafil has been working with BRE for the past year to become one of the first flat roofing manufacturers to have its thermal details certified.

Since the introduction of the revised Part L building regulations, which deal with energy efficiency requirements, architects and specifiers are now actively encouraged to use details with thermal values attached, otherwise they may have to pay a penalty elsewhere.

Easily accessible and straightforward to use, all Sika Sarnafil’s thermal details have been redrawn and modernised with values that tie in with the requirements for Part L. The specifier can be confident that all Sika Sarnafil thermal details assessed under the new scheme will perform as described, as well as being of a very high quality.

Becoming part of the Certified Thermal Details scheme is part of Sika Sarnafil’s ongoing commitment to promoting positive, sustainable change in the industry, as Sika Sarnafil’s Martin Bidewell, technical services manager for Single Ply Roofing, explains:

“Insulation used in roofs and walls to maintain heat works well, but this can fall down at junctions and thermal bridges where heat can escape. Recent research has shown that thermal bridging can be responsible for up to 30 per cent of a dwelling’s heat loss, which is really significant.

“Independent certification helps to address the problem of this performance gap – enabling us to build better buildings with superior thermal performance, which in turn are better for the environment. In addition there are serious cost savings for all parties involved in the project, not to mention those who will be paying the energy bills.

“Of course, all of this work to provide accredited details falls down if they are not installed properly. That’s why we fully train our registered contractors and have a dedicated Applications Team that visit projects, inspect work and give advice.”

Graeme Hannah, Scheme Technical Manager from BRE, adds:

“Since the launch of the Certified Thermal Details and Products Scheme at EcoBuild 2015 we’ve had an excellent response from industry, with both manufacturers and designers realising the value of accurate and independently assessed thermal performance values. The free to access searchable online database is constantly evolving, and the increasing number of high quality suppliers, such as Sika Sarnafil, undergoing certification demonstrates a positive step change in reducing the performance gap and enhancing building performance.”

The details are available to download via Sika’s new Sustainability Hub, a website packed with tools for those specifying projects with a sustainability requirement.
