Quickly and Easily Insulate Rim Joists

Using Foam it Green for Insulating Rim Joists

Insulating rim joists with Foam it Green is quick and easy to do. When you use Foam it Green, you create an air tight seal that can lower your utility bills, stop drafts, and improve your indoor air quality. And this project is EASY.

This quick and easy project can be done in just one hour!

And because the rim joist is such a critical junction point between the home and the foundation, people often report massive savings from using a small amount of spray foam like the small kit, Foam it 202.

Plan on using 2 to 3 inches thickness of cured foam in order to get both the air seal and a high r-value.

Depending on how long your walls are, or how thick you want the foam, you may find you need to use the large kit, the Foam it 602. Either way, pound for pound this is probably the lowest cost spray foam project with the most dramatic return for people. By using closed cell Foam it Green, the seamless air barrier and high r-value keeps your home much warmer in the winter and much cooler in the summer.

You also get a pest barrier to help keep insects and rodents out. And unlike fiberglass, Foam it Green never sags or settles, so once it’s in place, it’s done.

In a damp area like a rim joist, you absolutely want to use our closed cell formula. Plus, you’re much less likely to have mold issues because the anti-microbial formula has passed the very tough ASTM G-21 tests. Don’t be duped into using something else in such a vital area. Get your project done properly in record time and start enjoying the fruits of a simple job well done.
