Open Cell Spray Foam Insulation Services

Open cell spray foam insulation is cheaper per unit of R-value than closed-cell foams. Open cell does not provide all the features that closed cell foams do.

Lower R Value and Sound Deadening Properties

Open cell foams are lower in R-value (3.8 vs. 7.0). Open cell foams have tremendous sound attenuating properties (STC 38 in a 2×4 wall assembly) and make for a substantial air-seal at greater thicknesses. In open cell spray foam, the tiny cells of the foam are not completely closed. The trapped air causes the R-value per inch to be lower than closed cell foam, but it also makes it an amazing sound dampener! In fact, open cell spray foam is one of the best and most effective sound attenuators on the market.

Thicker Layer Required

Open cell spray foam may cost less than closed cell spray foam, but it has a lower R-value per inch, so a thicker layer is required. If the framing members are deep enough to accommodate your required R-value, open cell spray foam may save you money.

Open cell spray foam is vastly superior in performance to fiberglass, and although more expensive, has a relatively fast pay-back period (ROI) over fiberglass.
