DuPont™ Styrofoam™ Brand Deckmate™ Extruded Polystyrene (XPS) Foam Insulation* is an extruded polystyrene foam insulation with a planed surface designed for use in fully adhered conventional low-slope roof applications. It has excellent insulating characteristics, high resistance to water and water vapor, excellent freeze-thaw resistance, exceptional compressive strength and long-term durability.

Styrofoam™ Brand Deckmate™ Insulation can be used over any substrate in new construction or thermal upgrading of existing roofing when reroofing is required. The rigid foam insulation boards can be installed directly on structural steel decks beneath a non-bituminous sheet membrane or on a standing seam metal roof, eliminating the need for a thermal barrier.
