Spray Foam Insulation Closed Cell Vs Open Cell
In density or even higher for certain applications.
Spray foam insulation closed cell vs open cell. Closed cell and open cell spray foam do have different blowing agents. Closed cell foam can also increase the racking strength of attic walls which. However open cell and closed cell have their different uses. Open cell spray foam insulation cost open cell spray foam insulation costs 0 25 to 0 50 per board foot.
Open cell foam is full of cells that aren t completely encapsulated. Open cell tends to be roughly 0 5 lb cu. Architectural firms can specify both the building envelope for a total performance option. Closed cell spray foam is an incredible product below grade in your basement or crawl space because of its ability to block moisture see below.
