Rigid Foam Insulation provides both insulation and air sealing, provided that seams between foam panels are sealed with tape.

What are some pros to Rigid Foam Insulation? 

The different thicknesses of Rigid Foam are available to suit different application & R-value requirements. Rigid Foam panels are easy to cut and can be installed in any temperature. There are no harmful emissions during installation. Rigid foam is the one of the best installation options for insulating crawl space and basement walls. Some rigid foam panels include a radiant barrier for additional energy savings.


What are the cons of Rigid Foam Insulation?

R-value varies based on type of rigid foam. It can be as low as R-3.8 per in. or as high as R-8 per in. The installation is more time-consuming than spray foam due to the fact that you have to cut and fit each piece. Sometimes single-component spray foam must be applied around edges of rigid foam to seal and hold panel in place.


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.

Do you have more information on rigid foam insulation?

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 the 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.
