Closed cell spray foam


Closed cell

Closed cell spray foam insulation is one of the most efficient insulating materials available with a spray foam insulation r value above 6.5 per inch. The name closed cell comes from the cell structure of the finished insulation material. One cubic inch of polyurethane foam insulation contains millions of tiny plastic closed cells filled wih a blowing agent which is captured within the cells which contributes to highly efficient insulating properties. In addition closed cell foam provides an inherent air barrier with low moisture vapor permeability and excellent resistance to water. The density for closed cell spray foam is approximately two pounds per cubic foot. The medium density foam provides sheer and racking strength to wall assemblies in building applications. Closed cell spray foam insulation when properly installed can deliver energy savings of up to 50%. We highly recommen not using the do it yourself spray foam insulation because it will cost you double what we charge or even more. Also small imperfections in the building envelope not properly sealed will eventually lead to poor building performance or worse like moisture accumulation allergen/pathogen growth and possibly even structural failure. The solid nature and sealing capability of closed cell spray foam inhibits moisture driven elements.
