Closed Cell Spray Foam vs. Open Cell Spray Foam

The decision on whether to use open cell foam or closed cell foam becomes easier once all information is gathered on each. Some questions you may ask are, what's the difference or when should you use a specific type.

This table should help you see some basic differences between the open cell foam and closed cell foam.

Cell Structure soft, spongy hard, stronger
Density .5 lb/ cu. ft. 1.7 - 3.0 lb / cu. ft.
Properties sound deadening, better insulator compared to fiberglass stronger, better insulator, resistant to transmission of air & water vapor
Insulation Value R - 3.5 R - 6.0


Open Cell Spray Foam and Closed Cell Spray FoamDepending on the location of your spray foam insulation and your budget, you may be inclined to opt for one type of spray foam versus another. Because the closed cell foam type is more resistant to air and water vapor, this may be the wiser choice when insulating a basement or attic space. If you'd like to stay within a budget, the open cell spray foam may be the better choice for you.

Regardless, having been in business since 2014, HomeCore, LLC has the experience and expertise in working with both the open cell spray foam and closed cell spray foam.
