Dow Building Solutions receives BBA accreditation for XENERGY SL

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.

Products that receives Agrément Certificates are recognised by building control, government departments, architects, specifiers and industry insurers. It’s a mark of quality, safety and reliability that provides reassurance of the product’s fitness-for-purpose.

The BBA certificate provides designers and specifiers with independent data on performance, assuring them that XENERGY SL will perform as described if installed in accordance with the guidance set out in the certificate.

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%.

The result is reduced heat transfer during winter to keep a building warm, as well helping to keep it cool in the summer.

XENERGY SL - the first XENERGY product available in the UK - is designed to offer highly moisture-resistant flat roof insulation at reduced thicknesses versus conventional XPS alternatives. XENERGY SL offers a reduction of up to 4mW of thermal conductivity in various thicknesses.

XENERGY SL was launched to meet demand from architects and specifiers for a product with improved thermal performance of inverted roof insulation. It also fulfils their need for thinner materials which can offer greater design possibilities, including lower parapet heights.

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.

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.”
