Exterior sheathing is a crucial component in building construction, providing structural support and contributing to thermal insulation and moisture control. Plywood is a commonly used material for this purpose due to its versatility, strength, and resilience to environmental conditions. It consists of layers of wood veneer that are glued together, which gives it great durability and helps it withstand the elements, including wind, rain, and temperature fluctuations.

In addition, plywood can be treated to enhance its resistance to pests, such as termites, and can provide a solid base for siding or other finishing materials. It is also relatively easy to work with, allowing for a variety of installation methods that can suit different building designs and requirements.

Other materials, while useful in construction for different applications, do not possess the same properties that make plywood the standard choice for exterior sheathing. For example, gypsum board is primarily used for interior applications due to its susceptibility to moisture. Fiberglass, though valuable in various insulation roles, lacks the structural characteristics needed for sheathing. Slate, while excellent for roofing, is not practical for use as sheathing in most building applications given its weight and installation challenges.
