Dow Building Solutions have launched a new product to innovate the use of XPS in flat roofing. XENERGY™ SL is a flame retardant XPS product for use in inverted roof systems and offers a durable, attractive roof finish for roofs where heavy traffic is expected. In application, reduced thicknesses of the product can be used in comparison to conventional XPS alternatives.
XENERGY™ SL was launched to meet demand from architects and specifiers for an inverted roof insulation product with improved thermal performance. It also fulfils the need for thinner materials which can offer greater design possibilities, including lower parapet heights.
Through using CO2 as the blowing agent and adding infra-red blocking particles to scatter and reflect heat radiation within the foam board, the lambda values of XENERGY™ SL decrease by up to 11% compared to Dow STYROFOAMTM insulation boards. XENERGY™ SL also delivers a Global Warming Potential (GWP) of less than five and has an A+ rating in the BRE Green Guide.
The product has been endorsed by the British Board of Agrément (BBA), alongside being 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 specified.
