Housewraps

Unlike traditional vapor barriers that maintain the same permeability year-round, a vapor-variable membrane changes its vapor permeability based on seasonal conditions. During colder months, it helps limit interior moisture from entering the wall assembly. During warmer months, it becomes more vapor open to allow trapped moisture to dry. Learn more about VaporWise.

Housewrap is a weather-resistive barrier (WRB) installed behind exterior cladding to help protect wall assemblies from water intrusion while allowing moisture vapor to escape. It serves as a critical layer of the building envelope, helping manage moisture and support long-term building durability. Read Understanding Housewraps White Paper for a deeper dive.
