Made to reduce the harm of freeze-thaw cycles, Styrofoam™ Brand Roofmate™ XPS Insulation helps maintain a steady temperature in roof membranes – reducing damage during and after construction – and is reusable in many applications.
Thermax™ (ci)
Engineered for use on heavyweight decks (e.g. reinforced concrete) with a ballast layer of gravel or concrete slabs, Styrofoam™ Brand Roofmate™ Insulation helps the roof membrane maintain a steady temperature, minimizing the harmful effects of freeze-thaw cycles, weathering and physical damage during and after construction.

1Aged R-value at 1” of cured foam @ 75°F mean temperature. R-value expressed in ft2 •h•°F/Btu. R-value determined by ASTM C518 using the aging process in ASTM C1289 (90 days @ 140°F)
24Vertical compressive strength is measured at 10 percent deformation or at yield, whichever occurs first.
