GreenGuard® Building Wrap

Siding is designed to keep water out, but it’s also important that moisture is not sealed in. To this end, GreenGuard markets a variety of quality foam underlayments designed to work in concert with siding to ensure a house remains watertight, but still breathes. These products include Building Wrap, which provides a second layer of impermeability against water and air infiltration, allows moisture vapor to pass, will not sustain mold growth, and facilitates the drying process behind siding.
