Dow Building Solutions wins three prestigious contracts in London for XENERGY™ SL Roof insulation

Published:  26 September, 2016

Dow Building Solutions has secured three business wins in London for XENERGY™ SL – the innovative high performance, flame-retarded, XPS roof insulation product that was launched last year.

A total of 8000m2 of XENERGY™ SL has been specified for a prestigious new residential development in Chelsea that is worth an estimated £300m. Known as the Glebe, it is predicted to overtake One Hyde Park as the most expensive place to live in London. It comprises six top-end apartments, a duplex penthouse and two large detached villas.

At 399 Edgware Road, 3333m2 of XENERGY™ SL has been specified for a giant, 80,000 sq ft Morrisons foodstore. The store is being built in a new mixed-use, retail and residential-led redevelopment.

In Stratford, 2625m2 of XENERGY™ SL will be used at Capital Towers – a luxury development comprising 191 luxury homes overlooking the Queen Elizabeth Olympic Park.

The products for these three projects were all selected by Radmat Building Products Ltd, one of the largest suppliers of roofing and waterproofing systems within the UK.

Robert Speroni, Managing Director of Radmat, said: “As a company that specialises in providing roofing and waterproofing systems that offer a lifetime’s protection for buildings, we are always on the look-out for innovative, yet sustainable, products that complement our portfolio.

“We chose XENERGY™ SL for these projects because it reduced thickness insulation boards enhance thermal performance and allow for greater design possibilities, including lower parapet heights.”

Chris Gimson, Head of Commercial at Dow Building Solutions, said: “Dow is renowned for its ability to respond to changing customer needs and it created XENERGY™ SL to fill a clear gap in the market for a versatile product that offers improved thermal performance.

“XENERGY™ SL has set a new standard for roofing insulation and it is the perfect solution for these prestigious new housing developments in London, where its environmental attributes will deliver real and lasting value.”

Dow, inventor of the extruded polystyrene insulation STYROFOAM™, has developed XENERGY™ SL to achieve a significantly improved lambda insulation performance and to deliver a Global Warming Potential (GWP) of less than five. Through combining a manufacturing process which uses CO2 as the blowing agent and adding infra-red blocking particles to scatter and reflect heat radiation within the foam board, lambda values have been decreased by up to 11%.

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