ROOFMATE™ SL-A is the STYROFOAM™ Solutions for insulating inverted roofs. The boards are unaffected by the conditions encountered on flat roofs, including wide fluctuations in temperature and repeated freeze/thaw cycles.
ROOFMATE™ SL-A insulation is intended for use on heavyweight decks (e.g. reinforced concrete) with a ballast layer of gravel or concrete slabs. It can also be used in the ROOFMATE™ MinK system, a unique development from Dow Building Solutions which brings together ROOFMATE™ SL-A and a vapour-permeable separation layer, ROOFMATE™ MK.
The rainwater cooling effect (caused by rainwater flowing between the insulation and waterproofing membrane) requires an increase in insulation thickness in order to meet BS EN ISO 6946. However, this increase can be substantially reduced by using the ROOFMATE™ MinK system, which helps to minimise the heat loss due to rainwater cooling and therefore the amount of insulation required. Its rot resistance also makes it ideal for insulating green roofs. ROOFMATE™ LG-A - an insulation board with an integral 10mm thick mortar topping - is ideally suited for parapet/upstand insulation.
