VAPOR FREE

VAPORFREE® is a high-performance vapor barrier designed to retard moisture migration. This product is made from state-of-the-art polyethylene resins that provide superior physical and performance properties that far exceed the others. High tensile strength, unequaled puncture resistance, ultra-low moisture vapor permeability as well as resistance to decay make VAPORFREE® one of the most effective moisture barriers on the market today!... Air at 85 degrees and 60% RH has the same absolute humidity as air at 70 degrees and 100% RH. So venting 70F/100% RH crawlspace with 85F/60% RH air will not remove moisture, thus moisture moves from wet to dry... Where condensation or very high humidity occurs, mold and decay occur. In a crawlspace the temperature of the soil, living space and ductwork all contribute to lowering the overall crawlspace temperature. Outside air entering this area is often cooled to the point where condensation occurs, either on structural members or on ductwork.
