Dow Xenergy SL Roofing Insulation BBA Endorsed

Dow’s XENERGY™ SL roofing insulation product has been endorsed by the British Board of Agrément (BBA), which provides a recognised symbol of quality and reassurance for the construction industry.

It follows Dow’s recent success in becoming the first company to attain a coveted Green Guide Rating A+ by BRE Global for XENERGY™ SL, and the only XPS manufacturer to achieve this internationally recognised certificate.

XENERGY™ SL is a flame-retarded, XPS roof insulation product, which achieves significantly improved lambda insulation performance delivering a Global Warming Potential (GWP) of less than five.

By using CO2 as the blowing agent and adding infra-red blocking particles to scatter and reflect heat radiation within the foam board used for XENERGY™ SL, lambda values have been decreased by up to 11%.

Chris Gimson, Head of Commercial at Dow Building Solutions, said: “We are very proud that XENERGY™ SL has been endorsed by the BBA.

“The BBA certification provides yet more evidence of the quality of our product and further assurance for the construction industry that XENERGY™ SL will deliver all the benefits that Dow promises.”

XENERGY™ SL is manufactured at Dow’s production facility in King’s Lynn, Norfolk, where a wind turbine is used to generate renewable energy for the company’s manufacturing processes. This has resulted in a 13 percent decrease in the site’s electricity bill and contributes to Dow’s commitment to meeting its sustainability goals by 2025.
