Air Retarding Wrap

An air retarding wrap helps reduce infiltration, keeping homeowners comfortable and lowering their energy bills. Commonly referred to as housewraps, these products keep outside air from penetrating through the envelope and scavenging conditioned air. Studies have shown that a properly installed housewrap can reduce infiltration by as much as 13%. Housewraps also provide moisture protection for sheathing and framing, improving durability. There are several ways to take credit for infiltration reduction measures that go beyond the mandatory measures; installing housewrap is one way. These videos provide information about housewraps and their proper installation.

Air infiltration and exfiltration can account for 10 to 30% of the heating and cooling energy required for a California home. In this segment, energy expert Steve Easley and Carl Hagstrom, talk about proper window flashing techniques, and show how using a quality exterior air barrier system can control air filtration. Air barriers must integrate properly with other building components, particularly with window flashing.
