In gypsum construction, fasteners must be spaced a maximum of how many inches on center at all supports, including perimeter blocking?

In gypsum construction, proper fastening is essential for ensuring the structural integrity and performance of the drywall. The maximum spacing for fasteners at all supports, including perimeter blocking, is specified to be a maximum of 7 inches on center. This guideline is established to prevent sagging and cracking in the gypsum board, which can occur if the fasteners are too far apart and do not adequately hold the material in place.

By maintaining this maximum spacing, the load is distributed more evenly across the surface of the gypsum board, reducing the likelihood of problems over time due to settled or shifted materials. Adhering to this spacing requirement is critical for meeting building codes and ensuring that the installation complies with industry standards.

Other spacing options, whether higher or lower than this allowed maximum, do not align with these guidelines and could lead to installation failures or code violations. This highlights the importance of adhering to the specified fastener spacing to ensure effective performance of gypsum constructions.
