ThermalGuard OC1 is an open cell, 100% water-blown spray polyurethane foam insulation system with a density of 1 lb and an R-value of 4.7 per inch. When applied, ThermalGuard OC1 expands to over 50 times in size in approximately 8 seconds, filling and sealing building cavities of any shape and size. It achieves twice the yield of 2 lb spray foam while reducing waste and cleanup time by up to 50% compared to that of a ½ lb spray foam insulation.
ThermalGuard OC1 satisfies energy code in most climate zones at less than 4 inches and is designed to use in wall, attic and roof-deck applications where cavity depth is limited.
