What is the maximum screw spacing for Gypsum Board when fastening to wood?

When fastening gypsum board to wood, the maximum screw spacing recommended is 12 inches on center. This spacing ensures that the panels are securely attached and minimizes the likelihood of sagging or other issues that could arise from inadequate support. Proper fastening is crucial for the performance and durability of the gypsum board, particularly in areas subject to movement or stress.

Choosing a screw spacing greater than 12 inches on center could lead to insufficient support, increasing the risk of the gypsum board becoming loose, especially at the edges where stress is most likely to occur. Thus, maintaining the recommended maximum of 12 inches helps ensure compliance with building codes and standards, thereby contributing to a safe and stable structure.
