Florida Building Code Practice Exam

What is the maximum support spacing for fiberboard sheathing as per Florida Building Code?

1. 12" o.c.

2. 16" o.c.

3. 24" o.c.

4. 32" o.c.

The correct answer is: 16" o.c.

The maximum support spacing for fiberboard sheathing according to the Florida Building Code is 16 inches on center (o.c.). This specification is based on the need to provide adequate support to the sheathing material, which helps maintain its structural integrity and insulation properties. When the spacing exceeds 16 inches, the sheathing may not have sufficient support, potentially leading to sagging or buckling under load or during adverse weather conditions. The 16-inch spacing is a widely accepted standard, ensuring that the sheathing is adequately supported while also allowing for efficient construction methods. Adhering to this requirement can help prevent future issues related to durability and performance of the building envelope, which is critical for maintaining energy efficiency and minimizing moisture penetration.
