Projects – How to Quickly and Easily Insulate Rim Joists

I had quotes to insulate rim joists in a rental house: $850! I ordered the FOAM IT GREEN and went to work! It took me less than an hour to do it myself! And here’s the kicker: I’m a 52 y/o female, 5’2! HA! $500 still in my bank account! – Karen B., Painesville, OH

Use Closed Cell Foam it Green for Insulating Rim Joists

Insulating rim joists with Foam it Green is quick and easy to do. Plus the benefits range from much lower utility bills to reduced sound transfer.

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.

The rigid foam creates a pest barrier that helps keep insects and rodents out. And because it never sags or settles, once it’s in place, it’s done, unlike fiberglass. Plus, you’re much less likely to have mold issues with the anti-microbial formula.
