Dow Building Solutions has marked the commercial roll-out of XENERGYTM SL with an event for over 70 leading architects, specifiers and roofing contractors at the ICEBAR LONDON. Manufactured in the UK, this inverted roof insulation improves LAMBDA performance by up to 11 per cent. XENERGYTM SL has been formulated with the addition of infra-red blockers which are finely dispersed and incorporated into the extruded cell walls. The particles scatter and reflect heat radiation, resulting in reduced heat transfer during winter to keep a building warm, as well as in summer to keep it cool. The product will fully replace Dow??s STYROFOAM ROOFMATE SL-A product during 2015. Speakers and other notable guests at the event included Dusty Gedge, a recognised authority, designer, and consultant on green roofs, and President of the European Federation of Green Roof Associations, and representatives of the Department for Energy & Climate Change, the Construction Products Association and the Association for the Conservation of Energy.
