The term "sheathing" in carpentry refers to the material used to cover the framing system of a building. This is a critical component in the construction process, providing structural support and rigidity to the framework. Sheathing is typically made from materials such as plywood, oriented strand board (OSB), or other similar products.

In addition to structural support, sheathing acts as a base for exterior finishes, helps in the insulation of the building, and provides some protection against the elements. It also plays a vital role in creating a barrier against moisture infiltration, which is essential for maintaining the integrity of the structural system over time. Understanding the purpose and function of sheathing is fundamental for carpentry, as it directly impacts the durability and safety of the construction.

The other choices do not accurately define sheathing. The joint types refer to woodworking techniques, architectural styles pertain to design aesthetics, and finishing layers involve interior surfaces rather than the structural framework.
