Crawl Space Insulation Facts:

Fiberglass insulation cannot control or prevent air or moisture movement and infiltration. During the summer, warm humid air can flow around and create condensation, mold, and decay problems in the floor system. Even if your crawl space is "properly" insulated with fiberglass, it will not prevent warm or cold air from entering and contaminating the living space of your home.

The lack of ability to completely fill voids and openings caused by wiring, plumbing, ductwork, and narrow or wide joist spacing can also create issues when trying to insulate with fiberglass insulation. If the crawl space is not fully sealed from your home with Demilec Sealection 500, Agribalance, or Heatlok Soy, it is very likely that contaminated air, earth gases, mold, rodents, etc. can enter the living space. Spray foam insulation is the only product that will create an effective thermal barrier by sealing off all possible voids and openings from the underside of your home's crawl space.

Demilec spray foam in your home's crawl space is a superior insulation product that overcomes and surpasses the major disadvantages of other insulation products.
