Types of Insulation for Crawl Space Walls

There are a variety of insulation materials that can be used to insulate crawl space walls, including:

Fiberglass batts or rolls: Fiberglass is a popular choice for crawl space insulation because it is relatively inexpensive and easy to install. However, it is not as effective as some other types of insulation and can absorb moisture.
Cellulose insulation: Cellulose insulation is made from recycled paper and is a good choice for crawl spaces that are prone to moisture. It is more expensive than fiberglass, but it is more effective and can help to reduce noise.
Spray foam insulation: Spray foam insulation is a great choice for crawl spaces that are difficult to access or that have irregular shapes. It is more expensive than other types of insulation, but it is very effective and can help to seal air leaks.
