ZIP System Roof and Wall Sheathing panels are oriented strand board (OSB) structural panels with built-in protective overlays that eliminate the need for building wrap or roofing felt. Install the panels, tape the seams with Huber's ZIP System tape, and the building is rough dried-in. A wide range of roof coverings and wall claddings install directly over ZIP System Sheathings. When used on a wall, ZIP System Sheathing functions as a combination wall sheathing and code-recognized water-resistive barrier. The sheathing panel seams are sealed with ZIP System tape, protecting the wall system from water intrusion.
