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 ...
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.
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]

The first expanded polystyrene ICF Wall forms were developed in the late 1960s with the expiration of the original patent and the advent of modern foam plastics by BASF. [citation needed] Canadian contractor Werner Gregori filed the first patent for a foam concrete form in 1966 with a block "measuring 16 inches high by 48 inches long with a tongue-and-groove interlock, metal ties, and a waffle ...

An assortment of polyurethane foam products for cushioning and insulation. Polyurethane foam is a solid polymeric foam based on polyurethane chemistry. As a specialist synthetic material with highly diverse applications, polyurethane foams are primarily used for thermal insulation and as a cushioning material in mattresses, upholstered furniture or as seating in vehicles.
After many years of exploration and attempt, EPS lightweight concrete can be used in many building structures, such as EPS insulation coating, EPS mortar, EPS sealing putty, EPS lightweight mortar, EPS concrete inner and outer wall panels, etc. [4] In addition, EPS lightweight aggregate concrete is also used in the fields of pavement backfill ...
