Open-Cell

Open-cell spray foam insulation has tiny cells which are not completely closed. Open-cell is usually less expensive because it is developed using fewer chemicals. Open-cell is superior as an air barrier, and is sponge-like in appearance. It is often used to insulate interior walls because it minimizes outdoor noise intrusion. It is not recommended for outdoor applications.

Closed-Cell

Closed-cell spray foam insulation is a higher-density foam than open-cell. The structure of the actual cells are more compact. It is both an air barrier, water-resistive, and vapor barrier. Closed-cell can be installed anywhere in the home.
