Styrofoam™ Roofmate SL-X extruded polystyrene (XPS) thermal insulation distributed by DCTech, is designed for installation above waterproofing membranes in protected membrane roof (PMR) applications. Styrofoam™ Roofmate SL-X XPS rigid insulation boards are unaffected by the conditions encountered on flat roofs including wide fluctuation in operating temperature or repeated freeze/thaw cycles.

Styrofoam™ Roofmate SL-X XPS thermal insulation offers a long term retained R-value, high compressive strength and superior moisture resistance, making Styrofoam™ Roofmate SL-X XPS the perfect solution wherever superior load bearing and high insulating capabilities are specified.
