Make your home more comfortable and less expensive to operate with a well insulated crawl space.
Crawl Spaces are an area of the home that can be problematic. Most crawl-spaces are not insulated and are full of moisture, they can harbor mold and add moisture to the home raising the relative humidity. From time to time we do find fiberglass insulation that was installed to the floor and a lot of them have fallen down. Also, fiberglass tends to absorb moisture which affects the R-value and can allow mold to grow.
Insulating the Crawl-Space
There are two ways to insulate a crawl space. The less expensive and most common way is the insulate the perimeter along the stem wall with XPS Foam Board. This fits most applications best because less materials required. The other option is to insulate the floor of the home with cellulose insulation installed by using netting reinforced with nylon strapping. This gives an excellent amount of insulation, although this only works with a dry crawl-space. Dry crawl spaces can be dry naturally, but that is rare. A dry crawl space can also be created by lining the floor with plastic membrane and sometimes also require a dehumidifier for a backup.
