Help Desk Question: How important is 1/32 of an inch?

Fri, 08 Feb 2008 15:27:00 -0700

Question: I specified 1/2-inch roof sheathing for a commercial building. When I was inspecting the project I found that the contractor had installed 15/32-inch. What can be done to correct the situation?

Answer: A wood structural panel that is 15/32 inch thick contains six percent less wood fiber than a 1/2-inch thick panel. The effect on structural properties and characteristics is negligible. In most applications, the 1/32 of an inch difference in thickness of span-rated wood structural panels does not affect performance. In fact, assuring adequate performance in specific applications is at the heart of APA’s rigorous program of quality auditing and testing.
