Quickly and Easily Insulate a Crawlspace

Last year, I paid a professional spray foam company $9,000 to spray parts of my home. This year, I sprayed two Foam it Green 602 kits on the ceiling and rim joists of the crawl space. It was a piece of cake and a big success! – Eileen F., NJ

Use 2-3 inches Closed Cell Foam it Green for Insulating a Crawlspace

Insulating a crawlspace with spray foam insulation is a great way to stop drafts and pests. Crawlspaces are often big energy wasters and bring all sorts of opportunities for improvement. Foam it Green spray foam makes this project quick and easy to do. Plus you can get much lower utility bills with fewer hassles like pests, rodents, drafts, and smells.

Generally speaking, the main objective of spraying a crawlspace is to seal off the living area. If you are heating and cooling the basement you insulate the walls of the crawlspace. This keeps outside air outside and vice versa. If not, you just do the top of the crawlspace.

Sometimes crawlspaces have dirt floors. You don’t want to spray the dirt floor because it won’t adhere fully. You just need to decide if you want to heat and cool the crawl space. If you do, then you spray foam the outer walls so that the building envelope incorporates the crawl space. If you don’t, then you use spray foam to isolate the crawlspace from the rest of the living area. Makes sense, right?

When you’re doing a crawl space you absolutely want to use our closed cell anti-microbial formula. Please don’t be lured by fiberglass or open cell spray foam. They absorb moisture and rodents and pests love fiberglass. Worse still, fiberglass won’t stay in place and it wont stop air leaks.

And you want something that’s passed the tough ASTM G-21 Anti-Microbial tests. Crawlspaces are known for moisture and mold. This is an important time and place to get this right.

By using closed cell Foam it Green, you’re getting a seamless air barrier and high r-value. That tight air seal can be magical in making your home much more energy efficient and much more comfortable. Foam it Green doesn’t sag or settle, so once you’re done, you’re done.

With all of the above, crawlspaces seem to have the widest variety of how they show up. Please call our friendly Chicago-based team at 1-800-516-0949 to discuss any deviations from the norm.
