House Wrap Fabric

Housewrap is generally a woven synthetic material used to protect buildings. It is a replacement for the older asphalt-treated paper, or asphalt saturated felt. These materials are all lighter in weight and usually wider than asphalt designs, so contractors can apply the material much faster to a house shell. Housewrap functions as a weather-resistant barrier, preventing rain from getting into the wall assembly while allowing water vapor to pass to the exterior. If moisture from either direction is allowed to build up within stud or cavity walls, mold and rot can set in and fiberglass or cellulose insulation, Radiant barrer film will lose its R-value due to heat-conducting moisture.
