DECKMATE™ XPS Insulation

DECKMATE™ Insulation is a STYROFOAM™ Brand extruded polystyrene (XPS) foam insulation with a planed surface. It is designed for use in fully adhered conventional low-slope roof applications. Available in flat and tapered board stock, the rigid foam insulation boards can be installed directly on structural steel decks beneath a nonbituminous sheet membrane, eliminating the need for a thermal barrier. It has excellent insulating characteristics, high resistance to water and water vapor, excellent freeze-thaw resistance, exceptional compressive strength and long-term durability.

    1 R means resistance to heat flow. The higher the R-value, the greater the insulating power.
    2 Vertical compressive strength is measured at 10 percent deformation or at yield, whichever occurs first.
    3 Based on 1” (25mm) thickness.
    4 These numerical flame spread and smoke developed ratings are not intended to reflect hazards presented by this or any other material under actual fire conditions.
    5 Tested at 158°F/97% RH/7 days.
