In a crawlspace home, a vapor barrier is installed to reduce moisture and gases that enter from evaporation and diffusion through the floor and/or foundation or poured walls. This is a very important step to minimize moisture, which termites seek to survive. A vapor barrier can also aid in eliminating or minimizing mold, mildew, wood rot, floor failure, odors, and other insects and that is just to name a few. A vapor barrier can also aid in minimizing your heating and cooling bill, which is a great concern for many homeowners. Your sales representative can discuss pricing options and installation with you to ensure proper relevance to your home.
