EPD: Polystrene foam insulation, R = 5.3 m2K/W, 8 ft x 4 ft, 0.744 kg/m2, Styrofoam™ (Dupont)

DuPont’s XPS insulation primarily consists of polystyrene foam and a blend of blowing agents. Additionally, some of the products under review are lined with films or facers that help prevent water and water vapor intrusion into the insulation foam, meaning less potential for mold and mildew in the building envelope. All of DuPont’s XPS insulation products offer consistently high, long-term thermal resistance to reduce energy costs, are moisture resistant to increase resiliency, and are availablle in a variety of thicknesses and edge treatments to meet today’s design demands.
