UL723)class 1 (Class A)spray foam insulation. <br /> The product is formed by the reaction of proprietary resin Flame Spread Index<25 <br /> blend and polymeric methylene diphenyl diisocyanate. The Smoke Developed Index<450 <br /> resin blend is comprised of Polyols, additives, fire retardants Thickness 4 inches <br /> and low global warming potential blowing agents. The These numerical flame spread values are not a true reflection <br /> proprietary system is specially formulated to reduce reaction on how this or any material will perform in actual fire <br /> exotherm during application and provide improved <br /> conditions. <br /> dimensional stability. <br /> The spray applied nature of NexsealTM 2.0 LE spray foam allows Thermal Barriers: <br /> the material to flow into voids and seal cracks, expanding to NexsealTM 2.0 LE spray foam must be separated from the <br /> form a monolithic structure with high R-value (resistance to interior of the building (occupied space) by an approved 15 <br /> heat flow). NexsealTM 2.0 LE spray foam can form various minute thermal barrier such as%" inch gypsum board or other <br /> control layers for buildings and structures: insulation, air equivalent material.
