Closed Cell Spray Foam in Pocatello, ID

Dense, high R-value foam that seals air, blocks moisture and adds strength.

Closed cell spray foam is the densest, highest-performing insulation we install, at roughly R-6 to R-7 per inch. At about two inches it also acts as a vapor barrier, so it stops both air and moisture.

That makes it the right choice for metal buildings and pole barns that drip condensation, crawl spaces and rim joists that let cold air under the floor, and any spot where you need the most insulation in the least space.

Closed cell foam also bonds to the surface and stiffens it, adding strength to walls and metal roof panels.

Frequently Asked Questions

How thick should closed cell foam be?

It depends on the space. Many shops get 1 to 2 inches on the walls and 2 to 3 inches on the roof; homes often need more. We'll recommend a thickness based on how you use the building.

Is closed cell worth the extra cost?

Where you need a vapor barrier, maximum R-value in a thin space, or condensation control on metal, yes. For interior walls and sound control, open cell is often the better value.
