Enverge Nexseal spray foam insulation is a spray-applied, two component, closed cell polyurethane foam insulation system compliant with ASTM C-1209 Type II foams. The product is formed by the reaction of proprietary resin blend and polymeric methylene diphenyl diisocyanate. The resin blend is comprised of Polyols, additives, fire retardants, and Solstice LBA by Honeywell, which is based on hydrofluoroolefin (HFO) technology.

The spray applied nature of Nexseal spray foam allows the material to flow into voids and seal cracks, expanding to form a monolithic structure with high R-value (resistance to heat flow). Nexseal spray foam can form various control layers for buildings and structures: insulation, air barrier, moisture retarder, and weather barrier.
