Fire protection meets thermal insulation The hybrid insulation system combines the best of both worlds: The EVAROC® rock wool insulation board in the upper layer provides optimized fire protection, while the EVAPIR® insulation board made of rigid polyurethane foam underneath offers excellent thermal insulation. This combination creates an innovative hybrid system from a single source with a slim profile, low weight, and good compressive strength—and all this as part of a complete roof structure. For permanently secure and watertight roofs that impress in every respect—typical alwitra.
