What makes rigid foam insulation different

The key difference between rigid foam insulation and traditional insulation is, as you might expect, the strength of the material. Unlike batt and blown insulation, rigid foam won’t blow or shift out of place once it’s installed. It also is water and pest resistant, making it perfect for basements and crawl spaces.

Rigid foam insulation also offers benefits as air barrier, which can be accomplished when the boards are sealed at joints and edges with tape and spray foam. Rigid foam panels come in a variety of thicknesses and widths, but 2-ft. x 8-ft. and 4-ft. x 8-ft. panels are most common. Rigid foam cuts easily with a knife or saw to fit unusually shaped areas, and it’s typically cut to fit and wedged (friction-fit) into place. If needed, it can also be glued to surfaces with caulk, panel adhesive or spray foam.
