Many homeowners have not given much thought to the insulating needs of the crawl space below their homes, but they should know that it’s a necessary component of the overall insulation system of your home. Excess moisture can enter through vents that are meant to relieve moisture. This can be especially problematic during warm, humid months, when the crawl space can reach as low as 20 degrees below outdoor temperatures. When this occurs, the warm, humid air from outside cools off to the lower temperature in the crawl space, which causes moisture in the air to condense and fall on the cooler surfaces. If left untreated, this excess moisture can damage the structure of your home by growing mold and rot.

Fortunately, a variety of different materials and methods exist for insulating the crawl space. Closed cell spray foam, for example, is the most effective option because it does not sag like fiberglass batts. In addition, closed-cell spray foam also seals in nooks and crannies, preventing the crawl space air from entering the living space. This makes closed-cell spray foam the better option over fiberglass batts, which are prone to moisture and mold problems.
Closed-cell spray foam is an excellent choice for the crawl space, as it prevents moisture from moving through the open spaces in the crawl space. This type of insulation can also be used as a roofing material, as it can be applied directly to concrete, asphalt shingles, or wood. This product can also help protect the roof from damaging weather. In addition, closed-cell spray foam can also be applied directly to concrete or wood.
Installing a vapor barrier on the walls of the crawl space is a great way to prevent moisture and harmful gases from entering the home. Use a product that can seal the area and is made of 6 mil plastic. Then, overlap it six inches, seal it with high-quality tape, and extend it up to 12 inches along the foundation wall. Finally, apply glue or foam to the vapor barrier and adhere it to the foam.
Unlike fiberglass batting, spray foam insulation creates a seamless monolithic seal. Closed-cell foam is applied over a 12-mil poly liner that attaches to the walls. Then, closed-cell foam is sprayed into the joist ends, down the walls, and into the void between the walls. The finished product is a monolithic seal of the crawl space. In contrast, fiberglass insulation can be compressed by the wire insulation hangers, which makes the installation process difficult.
Crawlspace spray foam insulation has many benefits over traditional fiberglass insulation. The foam can seal small gaps and cracks to improve air quality in your home. In addition, it can also reduce energy costs by improving HVAC performance. You’ll have a better indoor air quality with less energy and fewer problems with mold and mildew. So, you should give it a try. You’ll be glad you did.
