Fiberglass insulation in a crawl space ceiling can easily absorb moisture, which causes the material to clump together, lose R-value and fall onto the crawl space floor.
Many homes with crawl spaces have wet, sagging and fallen insulation that actually does more harm than any good.
Although fiberglass batt insulation can perform well in the upstairs walls, it tends to get wet and heavy when installed in a crawl space ceiling, especially when the crawl space is vented to the exterior.
Moist air that enters the crawl space from the outside condenses on cool surfaces in the crawl space –including crawl space ceiling joists and sheathing.
Fluffy fiberglass batts get heavy when they absorb moisture. This causes the insulation to lose its R-value, compress into clumps and fall out of place –often ending up on the crawl space floor.

Unlike fiberglass insulation, rigid foam insulation won’t absorb moisture, lose R-value or fall out of place. It’s installed against crawl space walls as part of the crawl space sealing process.
In the past, builders installed fiberglass insulation throughout a house because it was inexpensive and widely available. Unfortunately, thousands of damp, messy and moldy crawl spaces have proven that this treatment is incorrect.
Today, building scientists, the engineers who study home performance — recommend that crawl spaces be encapsulated or sealed, and insulated with rigid foam insulation instead of fiberglass.
The sealing process ensures that air that’s too hot, too cold or too moist can no longer enter the crawl space. Instead of installing fiberglass insulation between joists in the crawl space or the floor above a crawl space, rigid foam insulation is installed against crawl space walls.
This type of insulation is ideal for use in crawl spaces and basements because it won’t absorb moisture, lose R-value, compress or fall out of place. By sealing and properly insulating the crawl space, this under-house area remains clean, dry and energy efficient.
