Spray polyurethane foam (SPF) insulation is a spray applied polyurethane foam which seals cracks, gaps and voids by expanding up to 120 times its volume into a semi-rigid insulation and air seal. High air permeability of traditional insulations allows air to easily pass through walls where the gaps and seams exist. These air infiltrations is what reduces the thermal performance of traditional insulations. Foam Insulation Chagrin Falls
Spray foam insulation is available in two forms: Open-cell foam and Closed-cell foam.
Open-cell foam is soft and spongy with a light open texture, the cells of the foam are broken and air fills the “open” spaces, and has excellent sound absorption qualities. This type of foam in most commonly used in walls and attic spaces. This foam offers an R-value of 3.5 per inch sprayed.
Closed cell foam is hard and rigid with a dense texture, the cells of the foam are closed and compact, and offered added strength to the structure. This type of foam is most commonly used in commercial metal building structures, under home foundations, and applied to ductwork. This foam offers an R-value of 6 per inch sprayed.
