Enverge EasySeal.5 spray foam insulation is a spray-applied, two component, open cell polyurethane foam insulation system. The product is formed by the reaction of a proprietary resin blend and polymeric methylene diphenyl diisocyanate.  The resin blend is comprised of polyols, additives, fire retardants and blowing agents.  The spray applied nature of EasySeal.5 spray  foam allows the material to flow into voids and seal cracks, expanding to form a seamless thermal envelope. EasySeal.5 is an air barrier, with high yield and high R-value (resistance to heat flow).
