Sheathing in construction
In the construction industry, the term ‘sheathing’, or 'sheathing board' can be used to refer to a layer of board or panel material that forms a part of floor, wall and roof assemblies. The outer sheathing board strengthens the assembly, provides a surface for other materials to be applied to and may give some degree of weather resistance.
Floor sheathing is typically a tongue and groove material that carries live loads down to the floor joists beneath. It is generally installed after a floor frame and been built but before the walls have been built up.
