Hydrofilament Drainable Housewrap offers 140 times more drainage than standard housewraps. Filaments are bonded to the exposed face creating a 1-mm space to the cladding's interior face. The space promotes moisture management for the wall assembly. A breathable structure allows moisture vapor to pass outward through the interior wall.
