STYROFOAM ROOFMATE Product Information Sheet (29KB PDF)
STYROFOAM™ ROOFMATE™ extruded polystyrene insulation with fabric and ballast is installed above waterproofing membranes. This helps keep the membrane at a more steady temperature and minimizes the harmful effects of freeze/thaw cycles, weathering and physical damage during and after construction – the most common causes of premature roof failure. STYROFOAM ROOFMATE extruded polystyrene insulation offers high R-value, compressive strength and moisture resistance for protected membrane roofing applications. CAN/ULC S701 Type 4.

**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.
