What is the minimum thickness of wood structural panels that can be used by exception?

  1. 1/4"

  2. 3/8"

  3. 7/16"

  4. 1/2"

The correct answer is: 7/16"

The minimum thickness of wood structural panels that can be used by exception is established to ensure adequate performance and safety in construction. In this context, wood structural panels refer to materials like plywood or oriented strand board (OSB) that are used in various applications, including roofing and wall sheathing. The correct choice is based on established building codes and standards, which often designate 7/16" as the minimum thickness for wood structural panels to meet specific structural and performance criteria. This thickness is sufficient to provide the necessary strength, stiffness, and durability required in typical construction scenarios, while also being lightweight and manageable for installation purposes. Choosing a thickness less than 7/16" could compromise the panel's structural integrity and its ability to withstand loads imposed by wind, snow, or other environmental factors. Therefore, this minimum thickness is crucial to maintain overall safety and reliability in construction practices involving wood structural panels.
