Insulation products specialist Dow Building Solutions has expanded its range of ROOFMATE SL-A STYROFOAM in response to industry demands.

The famous blue extruded polystyrene insulation foam – manufactured in the UK at Dow’s STYROFOAM plant in King’s Lynn - is now available in thicknesses up to 200mm as roofing contractors aim to support developers in meeting increasing thermal efficiency targets.

ROOFMATE SL-A - which is only available from Dow Building Solutions and its distributors - has high compressive strength, excellent water resistance and long term durability, making it the first choice of some of the UK’s biggest names in roofing.

The product was used in major developments such as the Westfield shopping centre in White City, The Elements retail park in Livingstone, the revamp of Union Square in Aberdeen and is currently being installed on several Olympic Park projects.

ROOFMATE SL-A is an ideal solution for insulating flat, inverted roofs as the insulation boards are unaffected by conditions encountered in such environments, including wide fluctuations in temperature and repeated freeze/thaw cycles. It’s intended for use on heavyweight decks such as reinforced concrete with a ballast layer of gravel or concrete slabs.

ROOFMATE SL-A can also be used in Dow’s ROOFMATE MinK system, which reduces the rain water cooling penalty and helps minimise the insulation thickness required.

All of Dow’s STYROFOAM-A products use carbon dioxide as the main blowing agent, resulting in an Ozone Depletion Potential (ODP) of zero and a Global Warming Potential (GWP) of less than five.
