Elevate RESISTA flat and tapered roof insulation consists of a closed cell polyiso foam core laminated to a specially coated, inorganic, fiberglass facer. RESISTA roof insulation provides outstanding fire, wind and thermal performance for single-ply and modified bitumen commercial roofing applications. All Elevate polyisocyanurate foam insulations use EPA accepted blowing agents and qualify under the Federal Procurement Regulation for Recycled Material. Flat and tapered RESISTA insulation with ISOGARD™ foam technology incorporates a HCFC-free blowing agent that does not contribute to the depletion of the ozone (ODPfree). Additionally, Elevate RESISTA insulation is a formaldehyde free material.
