For particleboard wall sheathing on wood studs spaced 16 inches, what thickness is required?

• A. 1/4 inch
• B. 3/8 inch
• C. 1/2 inch
• D. 5/8 inch

Answer: (B)

The correct thickness for particleboard wall sheathing on wood studs spaced 16 inches is 3/8 inch. This thickness is specified because it provides sufficient strength and rigidity to support the loads that may be applied to the wall and to help prevent buckling, especially in a structural application.

In building codes, the requirements for wall sheathing materials, including their thickness, are determined based on factors such as the spacing of the studs, anticipated loads, and overall structural integrity. The 3/8 inch thickness strikes a balance between adequate support and ease of installation, making it a standard choice for this application.

Thinner options like 1/4 inch might lack the necessary strength for structural purposes, while thicker options like 1/2 inch and 5/8 inch could be unnecessarily heavy and difficult to work with in most residential constructions where 3/8 inch would be sufficient.
