What Is Spray Foam Insulation & Why Is It Needed?
Spray foam insulation is a two-part system that, when combined, reacts to produce a substance with a foam-like consistency. Once applied, this type of insulation expands quickly and hardens to create a durable barrier.
How Does Spray Foam Insulation Work?
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 fills a cavity to add R-value and prevent air leakage, helping to keep energy bills low. Spray foam insulation can also increase the strength of your home by helping increase stability during high winds and severe storms.
Types of Spray Foam Insulation
Our spray foam contractors use one of two types of spray foam when insulating a home: open-cell spray foam insulation or closed-cell spray foam insulation. Open-cell spray foam is less dense as the cells in the foam are “open.” 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
This spray foam has a density of 0.5 pounds per cubic foot. It is made up of cells of foam that are not entirely closed. The cells are broken, and air fills all 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
This 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. This foam is dense and therefore has greater insulating properties. Closed-cell spray foam insulation has an R-value of 5.4 to 7.2 per inch.
