Sheathing is the supporting structure that acts as a cover for the surfaces of a building. The main function of sheathing is to provide a surface where other materials can be applied to, either on either floors, roofs, or walls of structures. It also provides additional structural integrity to buildings.
What are the 3 purposes of sheathing?
Sheathing serves several purposes: It protects against the elements, provides a foundation for materials like roofing, siding, and flooring, and fortifies the structure against internal and external forces. There are several different types of sheathing: exterior wall, floor, and roof.
Is sheathing just plywood?
Sheet sheathing is wide, flat sheets of wood.
The two types of sheet sheathing are plywood and OSB. OSB (oriented strand board) is the most popular choice for sheathing today. It's made of wood chips and strips that are compressed together to form a flat 7/16” sheet.Is plywood sheeting or sheathing?
Where does sheathing go on a house?
Wall sheathing is primarily a structural material. It is attached to the exterior wall framing and prevents walls from swaying or bending. Builders use sheathing as a nailing base for siding, creating the walls of a building.

Frequently Asked Questions
What is sheathing used 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.

What does OSB mean in construction?
Oriented Strand Board
Hear this out loudPauseOriented Strand Board is a widely used, versatile structural wood panel. Manufactured from waterproof heat-cured adhesives and rectangularly shaped wood strands that are arranged in cross-oriented layers, OSB is an engineered wood panel that shares many of the strength and performance characteristics of plywood.
What are the disadvantages of OSB?
Hear this out loudPause“The major disadvantage of OSB is that if it gets exposed to significant amounts of water or moisture, the edges expand by up to 15% ... especially if they are cut edges. This swell will then telegraph onto the shingles or some flooring," according to PATH.
Which is better plywood or OSB?
Hear this out loudPauseOSB is generally less expensive than plywood. OSB is more uniform, with fewer voids, soft spots, or gaps. OSB is considered by many to be a more environmentally friendly product since it can be made from scrap and smaller trees, rather than old-growth trees. OSB does not delaminate, as plywood can.
