Projects – How to Quickly and Easily Insulate Basement Walls

Installing Foam it Green on the basement walls as part of a finished basement project I was able to cut my heating costs drastically…I’m now heating twice the square footage for approximately 30% less than I did during last years mild winter. – Michael G. Howard, PA

Use Closed Cell Foam it Green for Basement Walls

No one should use fiberglass to insulate a basement anymore. Fiberglass doesn’t stop air, water, mold, bugs, rodents or radon.

Foam it Green Closed Cell spray foam is the quickest and easiest way to insulate any type of basement wall. Concrete wall? Stone wall? Brick? No problem. Spray foam insulation gets into all the cracks and crevices to provide a complete air and moisture seal.

Foam it Green’s continuous air barrier means:
Lower heating and cooling bills
A block for radon gas
A block for bugs and rodents
A block for mold growth thanks to our Anti-Microbial additive
A more comfortable room
Warmer upper-level floors in the winter

By using closed cell Foam it Green, you create a seamless air barrier and high R-value that will keep your home much warmer than before in the winter and much cooler in the summer. Since the basement is where the cold comes into a house in the winter, spraying Foam it Green creates a solid foundation for energy savings in the whole home.

Foam it Green never sags or settles. Once it’s in place, it’s done!

The space allows for the foam to seal behind the studs, creating a continuous air and insulation barrier.) Apply closed cell foam to achieve 1” cured layers, making sure the foam is applied to the joints connecting the studs to the substrate.

2) Spray additional closed cell foam to achieve 1” cured layers each, to the desired final depth. (Fig. 4)

3) If the foam expands past the studs, it can be trimmed flat with any serrated edge before enclosing the wall. (Fig. 5)

1) If the building is heated during colder months, and using a combination of insulation materials in the wall cavity you intend to close in with drywall or paneling, such as fiberglass, cellulose, rock wool, or open cell foam over the closed cell foam, it is recommended to apply a final minimum thickness of 2” of closed cell foam first. A
minimum thickness of 1” is recommended for climates in which no heat/furnace is used.

2) It is recommended to apply a vapor barrier before installing the desired wall covering such as drywall or
