DuPont™ Styrofoam™ Brand Roofmate™ XPS Insulation
Water-Resistant Insulation for Protected Membrane Roofing Systems
DuPont™ Styrofoam™ Brand Roofmate™ XPS Insulation
Water-Resistant Insulation for Protected Membrane Roofing Systems
<br><b>DuPont™ Styrofoam™ Brand Roofmate™ Extruded Polystyrene (XPS) Insulation</b> is designed for installation above waterproofing or roofing membranes in protected membrane roof (PMR) or green roof applications. <br><br> Engineered for use on heavyweight decks (e.g. reinforced concrete) with a ballast layer or gravel or concrete slabs, <b>Styrofoam™ Brand Roofmate™ XPS Insulation</b> helps the roof membrane maintain a steady temperature, minimizing the harmful effects of freeze thaw cycles, weathering and physical damage during and after construction.

1Long-term predicted thermal resistance value for 50 mm thickness.
2Thermal values are consistent with the criteria of ASTM C578 and are not assessed by the CCMC. Depending on the product, a 15-, 30- or 50- year limited thermal warranty is available.
4Vertical compressive strength is measured at 10 percent deformation or at yield, whichever occurs first. Since Styrofoam™ Brand Extruded Polystyrene Foam Insulations are visco-elastic materials, adequate design safety factors should be used to prevent long-term creep and fatigue deformation. For static loads, 3:1 is suggested. For dynamic loads, 5:1 is suggested.
5Water vapor permeance varies with product type and thickness. Values are based on the desiccant method, and they apply to insulation 25.4 mm (1.0-inch) in thickness. Thicker products have lower permeance.
