Spray foam insulation closed cell vs open cell.

Closed cell and open cell spray foam do have different blowing agents. Open cell is lightweight foam that is flexible and an excellent air barrier. When applied on the interior open cell spray insulation provides performance advantages that differ from those of closed cell spray foam used on the exterior. In other words the cells are deliberatly left open.

Open cell foams most commonly range from 5 lb to 7lb densities. Architectural firms can specify both the building envelope for a total performance option. Closed cell foam is roughly four times as dense as open cell for insulation applications.
