Zi3 a d VG9C7 let NexsealTM 2.0 LE piP I Spray Foam Insulation Division 7: Thermal & Moisture Protection polyurethane systems Product Description: ASTM E-84: NexsealTM 2.0 LE spray foam insulation is a spray-applied, two NexsealTM 2.0 LE spray foam is an ASTM E-84 (NFPA 255, component, closed cell polyurethane foam insulation system. UL723)class 1 (Class A)spray foam insulation. The product is formed by the reaction of proprietary resin Flame Spread Index<25 blend and polymeric methylene diphenyl diisocyanate. The Smoke Developed Index<450 resin blend is comprised of Polyols, additives, fire retardants Thickness 4 inches and low global warming potential blowing agents. The These numerical flame spread values are not a true reflection proprietary system is specially formulated to reduce reaction on how this or any material will perform in actual fire exotherm during application and provide improved conditions. dimensional stability. The spray applied nature of NexsealTM 2.0 LE spray foam allows Thermal Barriers: the material to flow into voids and seal cracks, expanding to NexsealTM 2.0 LE spray foam must be separated from the form a monolithic structure with high R-value (resistance to interior of the building (occupied space) by an approved 15 heat flow). NexsealTM 2.0 LE spray foam can form various minute thermal barrier such as%" inch gypsum board or other control layers for buildings and structures: insulation, air equivalent material. Consult local building codes for barrier, moisture retarder and weather barrier. requirements and restrictions.
