What does the term "sheathing" refer to in carpentry?

In carpentry, "sheathing" specifically refers to the material that is applied to the framing of a building to provide structural support and a base for the exterior finish. This sheathing is typically made from materials such as plywood, oriented strand board (OSB), or gypsum board and plays a crucial role in adding strength and rigidity to the building's framework. It aids in the distribution of external loads and helps with weatherproofing by providing an additional barrier against elements like wind and moisture.

The function of sheathing is multi-faceted, as it also facilitates the attachment of roofing, siding, and insulation, effectively contributing to the overall integrity and resilience of the structure. Understanding the role of sheathing is essential for anyone working in carpentry and construction, as it is a basic yet vital component of building.
