STYROFOAM DECKMATE Product Information Sheet (83KB PDF)
STYROFOAM™ DECKMATE™ extruded polystyrene insulation is used on conventional roofs beneath mechanically fastened, fully adhered, or ballasted sheet membranes. Also, BUR, modified bituminous and metal roofs. It can be installed directly on a steel deck without the use of a thermal barrier such as gypsum board. Custom sizes are available. STYROFOAM DECKMATE extruded polystyrene insulation has smooth, high-density skins, with a closed cellular structure and can be reused when the membrane must be replaced. If offers excellent insulating characteristics low water absorption, excellent compressive strength and meets CAN/ULC S 701 Type 2.

**Not all product sizes are available in all regions.
†R means resistance to heat flow. The higher the R-value, the greater the insulating power. R-values are expressed in ft2•h•°F/Btu.
††Vertical compressive strength is measured at 10% deformation (5% for STYROFOAM HIGHLOAD 40, 60 and 100 insulation products) or at yield, whichever occurs first. Since STYROFOAM extruded polystyrene insulation products are visco-elastic materials, adequate design safety factors should be used to prevent long-term creep and fatigue deformations.
