Exterior gypsum sheathing fasteners should be spaced how far apart?

• A. 4 Inches
• B. 7 Inches
• C. 9 Inches
• D. 12 Inches

Answer: (B)

When it comes to the proper installation of exterior gypsum sheathing, fasteners play a crucial role in ensuring the structural integrity and performance of the sheathing. The recommended spacing for fasteners is typically around 7 inches apart. This spacing provides an optimal balance between securing the sheathing to the framing underneath while also allowing for the necessary movement and expansion due to temperature and moisture changes. Having fasteners too far apart can lead to inadequate support, which may result in sagging, warping, or overall failure of the sheathing itself, especially under adverse weather conditions. Conversely, spacing fasteners closer than recommended can lead to unnecessary puncturing of the sheath and may weaken the material. Therefore, the specified 7-inch spacing helps maintain a secure installation that aligns with industry standards and best practices in construction.
