Rigid Foam Wall Insulation


SilverGlo rigid foam insulation allows both an air barrier and a thermal barrio.


Avoid Water Damage, mold and Losing R-Value

Rigid foam although not as popular as cellulose or fiberglass has found a lot of loyal follower with builder and homeowner who like it. It is perfect for wall insulation and other application.

Even though there are different kinds of rigid foam boards, all rigid foam has an advantage. Rigid foam will stop air leakage if it is sealed with special tape. Water will not be absorbed, nor will mold.



Perfect for masonry walls


Rigid foam have variations in width and thickness. They come in 2ft. x 8ft and 4ft by 8ft panels. Rigid foam is light in its weight and can be cut easily with a knife. Mostly rigid foam is used to insulate masonry walls. It can be glued to the masonry with adhesive and then masonry fastener can be sued to secure the panel. The laws require that fire-proofed material be used to cover the foam. Regardless it makes a thermal barrier allowing energy efficiency.

Three Types of Rigid Foam

Polyisocyanurate (a.k.a. polyiso) comes with the highest R-value per inch R-6 of any rigid insulation. A radiant barrier reflective foil is also paid on both sides for some application. This foam is more expensive than the other types of foam.

Extruded Polystyrene (XPS) rigid foam has two color: blue or pink. It has an R-value of about R-5 per inch and has a smooth plastic surface.

Expanded Polystyrene (EPS) is the budget friendly rigid foam and has an R-value of about R-3.8 per inch. Most of these foams are 3.8 per inch. Available in different thicknesses these offer versatility and air sealing
