Use 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.
How to Insulate 2x4 Walls
How to Insulate 2×4 Walls Quickly & Easily:
1) Follow all of the instructions in the included instruction manual regarding proper Foam it Green setup, project area preparation, and substrate readiness. Make sure that you have all of the tools required for the job (see Tools).
2) Apply closed cell Foam it Green to achieve a cured thickness of one inch, making sure the foam is applied to the joints connecting the studs to the substrate. (Fig. 1)
3) Spray additional layers of closed cell foam at cured thicknesses of one inch each to the desired final depth. (Fig. 2)
4) If the foam expands past the studs, trim flat with a serrated edge before enclosing the wall. (Fig. 3)
If the building is going to be heated during colder months, and will use a combination of insulation materials in the wall cavity (such as fiberglass, cellulose, rock wool, or open cell foam) it is recommended to apply a minimum thickness of 1.5” of a closed cell first. (A minimum thickness of 1” is recommended for climates in which no heat/furnace is used).
For most homes, it is recommended to apply a vapor barrier after installing insulation before the desired wall covering (drywall or paneling) goes up.
