InsulFoam SP is an engineered insulation consisting of a superior closed-cell, lightweight and resilient expanded polystyrene (EPS) with a durable and stable, factory-laminated coated glass facer. InsulFoam SP is available in a nominal density of 1lb/ft3 or 1.25lb/ ft3, and meets or exceeds the requirements of ASTM C578, Standard Specification for Rigid, Cellular Polystyrene Thermal Insulation. In addition, InsulFoam SP offers a long-term, stable R-value and has excellent dimensional stability, compressive strength and water resistance properties. InsulFoam SP is specifically designed for low-sloped roof applications that employ mechanically fastened or ballasted TPO, PVC and EPDM, as well as low-sloped built-up, modified bitumen and fully adhered single-ply roofs that incorporate cover boards or slip sheets. InsulRoof is also designed for use in fully-adhered fleeceback systems with compatable adhesives. Please consult local building codes and membrane manufacturers for system requirements. Sizes InsulFoam SP is available in several standard thicknesses. Nonstandard sizes may also be ordered; InsulRoof SP can be made up to a thickness of 6” (R-26), with a minimum thickness of 2” for 1 lb/ft3 insulation and 1.5” for 1.25 lb/ft3 insulation. Code Approvals. Insulfoam insulations are recognized in the International Code Council Evaluation Service (ICC-ES), and have numerous Underwriters Laboratory and Factory Mutual Approvals. Please contact your local Insulfoam representative for details. Environmentally Friendly. It does not contain any ozonedepleting blowing agents, may contain recycled material, and is 100% recyclable if ever removed or replaced. Stable R-value. The product’s thermal properties will remain stable over its entire service life. There is no thermal drift, so the product is eligible for an Insulfoam 20-year thermal performance warranty. Proven Performance. EPS has been manufactured using the same chemistry since the mid-1950s, providing proven performance. Water Resistance. InsulFoam SP does not readily absorb moisture from the environment.
