What Is Spray Foam and Why Do I Need it?

spray foam insulation sealing the floor and wall cornerSpray foam insulation performs a dual purpose of insulating and air sealing in one application. The foam expands upon installation and completely fills an opening, including any cracks and crevices. Some of the benefits of spray foam are preventing air leakage including humid Florida air, providing a sound barrier, helping to deter mold growth, and helping conserve energy.

Spray foam insulation is available in two types: open cell spray foam and closed cell spray foam.

Open cell spray foam is light and flexible. It is made of cells that are left open. As open cell spray foam dries, gas escapes from the cells through the cell walls, making the foam light and malleable.

Closed cell spray foam has a higher density than open cell spray foam and the cells are closed. Since closed cell spray foam is highly dense, it has better insulating properties and a higher R-value than open cell spray foam. Its density makes it more resistant to varying temperatures and weather conditions.
