Green "X" Series
 

Green "X" Series

ROOFMATE™ SL-X and ROOFMATE LG-X are the STYROFOAM™ Solutions for insulating inverted roofs. These boards are unaffected by the conditions encountered on flat roofs including wide fluctuations in temperature or repeated freeze/thaw cycles. ROOFMATE SL-X insulation is intended for use on heavyweight decks with a ballast layer of gravel or concrete slabs. Its rot-resistance makes it ideal for insulating roof gardens. ROOFMATE LG-X boards have a 10mm modified concrete topping on the upper surface, eliminating the need for separate ballast and making it possible to gain the benefits of the inverted roof on lightweight decks.
