Which material is often used for exterior wall sheathing?

Plywood or oriented strand board (OSB) is commonly used for exterior wall sheathing because of its structural integrity, strength, and versatility. Sheathing serves as a base for the exterior wall and provides support for siding materials, contributes to the overall rigidity of the wall structure, and helps with insulation and moisture control.

Plywood is particularly valued for its durability and resistance to warping, while OSB is favored for being more cost-effective and efficient for large structural panels. Both materials can effectively withstand outdoor elements when installed correctly, making them a superior choice for exterior applications compared to the other options listed.

Brick, while excellent for exterior finishes and load-bearing structures, is not typically used as sheathing. Vinyl is primarily a siding material and does not provide structural support to walls. Glass, while used in windows and some modern architectural designs, lacks the necessary structural properties to be employed as wall sheathing. Thus, plywood or OSB stands out as the most suitable and practical choice for this application.
