First company gets listed under new BRE Global thermal details and products certification scheme

Note: This press release is over six months old and the details may have been superseded. Please contact the Press Office for the latest information.

UK insulation manufacturer Xtratherm is the first company to be included in the certification listing of the new BRE Global Certified Thermal Details and Products scheme.

The scheme which was launched in March, aims to reduce the level of thermal bridging that can arise in buildings and homes causing heat loss. It certifies the ‘as designed’ thermal performance of junction details (SAP table K1 and other bespoke details), products (windows, doors and roof lights) and major building elements (wall, roof and floor systems).

It also enables suppliers to demonstrate that their products and services meet the appropriate performance standards, helping clients avoid costly mistakes and reduce risk.

Xtratherm, which is one of Europe’s largest manufacturers of rigid insulation products, submitted a full set of 25 junction details which were assessed by BRE experts and then independently certified by BRE Global (BRE’s certification company).

BRE Scheme Technical Manager Graeme Hannah said ‘Our aim with the scheme is to improve the energy performance and internal environment of buildings by providing independently and accurately assessed thermal details and products. I’m delighted that Xtratherm is the first company to submit details to the scheme – more companies are taking their lead and getting involved, we are starting to make a positive difference’.

The certified details will be accessible via a free online database aimed at manufacturers, suppliers, specifiers and designers. It will include a range of government accredited construction details, as well as BRE certified details, products and elements. The database will go live on 31st July.

Danny Kearney Technical Manager with Xtratherm said ‘We view this scheme as being a truly independent verifier of this most critical component in achieving an efficient building fabric. The concentration on U-values only, without looking at how insulation joins with other components gives an unreliable picture of overall insulation performance. The new cataloging and verification system will be a great asset to designers and building professionals not only in the UK but throughout Europe.’
