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.

Choose the right type of rigid foam for your needs

When choosing rigid foam insulation, you have three main options:

  • Polyisocyanurate: Known as polyiso for short, polyisocyanurate foam has the highest R-value per inch (R-6.5 to R-6.8) of any rigid insulation. This type of rigid foam usually comes with a reflective foil facing on both sides, so it can also serve as a radiant barrier. Polyiso board is more expensive than other types of rigid foam, but it offers the most benefits. Our Foamax® polyiso insulation comes with a foil vapor barrier on the back and a white foil finish on the front, providing quality insulation while also adding a clean finished appearance to the space.
  • Extruded polystyrene: Extruded polystyrene (XPS) rigid foam is usually blue or pink in color, with a smooth plastic surface. XPS panels typically aren't faced with other material. The R-value is about R-5. Like polyiso, this type of rigid foam won't absorb water and is stronger and more durable than expanded polystyrene, so it's probably the most versatile type of rigid foam. XPS falls between polyiso and expanded polystyrene in price.
  • Expanded polystyrene: Expanded polystyrene (EPS) is the least-expensive type of rigid foam and has the lowest R-value (around R-3.8 per in.). It's also more easily damaged than the other types of rigid foam. However, EPS foam is a good addition for budget conscious homeowners in areas where it won't be exposed to a lot of traffic.
