The structural panel layer applied to wall and roof framing that provides rigidity and a surface for exterior materials.
Sheathing is structural panel material — typically plywood or OSB — applied to the exterior of wall and roof framing to provide structural rigidity, lateral bracing, and a substrate for exterior cladding and roofing. Roof sheathing is also called decking. Sheathing is commonly covered with a weather-resistant barrier before cladding is applied.
