Coastal and Floodplain Construction Inspector's Practice Exam

What is the minimum thickness required for wood structural panels used for opening protection in one and two story buildings?

1. 1/4 inch

2. 1/2 inch

3. 7/16 inch

4. 1 inch

The correct answer is: 7/16 inch

The minimum thickness required for wood structural panels used for opening protection in one and two-story buildings is indeed 7/16 inch. This specification is based on building codes that dictate the structural integrity and performance of materials used in construction to ensure adequate protection against wind and debris, particularly in hurricane-prone areas. Using panels of this thickness provides the necessary strength and durability to withstand external forces while also ensuring that the panels are not excessively heavy, which would complicate installation and handling. Thicker options, although stronger, are not typically required for standard applications in one and two-story buildings, where 7/16 inch provides a good balance between performance and practicality. The other thickness options fall short of the regulatory requirements or are not applicable for the intended use, ensuring that 7/16 inch remains the established standard for proper opening protection.
