How Spray Foam Insulation Works

Spray foam insulation is a two-in-one product, insulating and air sealing in one step. Unlike fiberglass insulation, spray foam insulation expands when applied and completely fills a cavity to prevent air leakage and keep energy bills low. Spray foam wall insulation can also increase the strength of your home, helping to increase stability during high winds and severe storms.

Open and Closed Cell Spray Foams

Our spray foam installers use one of two types of spray foam when insulating a home: open-cell spray foam insulation or closed-cell spray foam insulation. The first, open-cell spray foam, is less dense as the cells in the foam are “open”.  The second, closed-cell spray foam, is denser as the cells in the foam are closed, creating more stability. Read on for more details about these two spray foam options.

Open-cell spray foam has a density of 0.5 pounds per cubic foot. It is made up of cells of foam that are not completely closed. The cells are broken and air fills all of the “open” space inside the material. Open-cell spray foam insulation has an R-value of 3.4 to 4.5 per inch.

Closed-cell spray foam has a density of 2.0 pounds per cubic foot. The cells are closed and packed tightly together. They are filled with gas that helps the foam rise and expand. Closed-cell foam is very dense and therefore has greater insulating properties. Closed-cell spray foam insulation has an R-value of 5.4 to 7.2 per inch.
