Insulate 2×4 Walls with Foam it Green

Easy to use, adheres easy, cleanup easy. Took no time at all to do 5 walls and presto done. It stopped the dampness in the downstairs area which has 2 walls below ground level. Got rid of the musty odor and looks great. – Frank S., NJ | Read More >>

Use 2-3 inches Closed Cell Foam it Green for 2×4 Walls

Insulating a 2×4 wall with Foam it Green is the quickest and easiest way to meet code standards. Code is all about sealing and insulating now. Foam it Green sprays on fast, creating a seamless air and moisture barrier. And, with an R-7 per inch, you get to R-21 in 3 inches of foam. Fiberglass doesn’t seal, and in most climate zones, it doesn’t have enough R-value to meet code in a 2×4 wall.

A seamless air barrier and high R-value:
Keeps your home warmer in the winter & cooler in the summer
Saves you a lot of money on energy bills
Stops uncomfortable drafts
Keeps out bugs and rodents
Improves the air quality in the room
Stops sound transfer
Stands up to flooding
Stops mold (there is an Anti-Microbial additive in Foam it Green)
And because spray foam never sags or settles, once it’s in place, it’s done!

You do not have to fill the entire cavity with spray foam insulation. You can leave empty space. You can do spray foam plus fiberglass or open cell if you wish, but if you use heat often in the winter, spray at least 2 inches of closed cell foam first.
