Sealection 500 spray foam R-3.8 (RSI-0.67) per inch. [12] a water-blown low density spray polyurethane foam that uses water in a chemical reaction to create carbon dioxide and steam which expands the foam. Flame spread is 21 and smoke developed is 217 which makes it a Class I material (best fire rating). Disadvantages: Is an Isocyanate.
Spray foam insulation or spray polyurethane foam (SPF) is an alternative to traditional building insulation such as fiberglass. A two-component mixture composed of isocyanate and polyol resin comes together at the tip of a gun, and forms an expanding foam that is sprayed onto roof tiles, concrete slabs, into wall cavities, or through holes ...
Cementitious foam insulation is a cement-based thermal and acoustic insulation, [1] with an R-value similar to that of fiberglass. [2] It is installed as a foam with a consistency like shaving cream, [2] or as pre-cast slabs. [3] The current cost is similar to that of polyurethane foams. [2]
