More about Historical: Closed Cell Spray Foam Insulation - 2015
Spray foam insulation (SPF) is a site applied foam insulation for residential, commercial, and industrial applications. SPF is a two-part polyurethane based foam and can be used in place of other insulating materials like batt insulation (fiberglass, mineral fiber) and loose fill insulation. SPF can be either open or closed cell and both can be used to create a continuous air barrier. Despite its higher cost, closed cell insulation has gained larger market share due to its higher R value and vapor barrier characteristics. Closed cell SPF can be used in various applications including interior or exterior walls, attics, foundations, HVAC ducts, etc. Since these products are reacted and applied on site, special care must be taken to avoid occupational exposure to the isocyanates, amines, blowing agents, etc. that volatilize during the application process. Special training is required for applicators of SPF, and there is a delay period before unprotected individuals can re-enter the application area. Offgassing from the SPF can occur for extended periods after installation. There is continued debate on the definition of full cure for SPF insulation and the amount of time needed for harmful levels of emissions to recede is highly contested.
