Invinsa resilient roof board is designed as a cover board component of the roof system. It provides a protective layer for the insulation, while adding stability to the membrane above to ensure maximum performance and longevity.
Its high-density polyisocyanurate technology is bonded in-line to coated fiberglass reinforced facers, providing resistance to water and hail. It has been tested in PVC, TPO and EPDM single-ply systems, as well as JMCleanBond SBS modified-bitumen roof systems and is approved for some class A applications by FM Global and Underwriters Laboratories.
