What is the screw spacing requirement for nails when installing 1/2 inch gypsum?

The correct spacing requirement for nails when installing 1/2 inch gypsum board, also known as drywall, is indeed 12 inches. This spacing is crucial to ensure proper support and adherence of the gypsum board to the framing.

Using a 12-inch spacing helps minimize the potential for sagging or cracking of the gypsum board, especially in ceilings where weight and tension are greater. Proper application according to the manufacturer's guidelines contributes to the overall integrity and performance of the wall and ceiling finishes, providing adequate sound and fire resistance as intended. Following these standards ensures that the installation adheres to building codes and best practices in construction.

Other spacings, such as 10, 14, or 16 inches, may not provide the same structural support or may be in conflict with the guidelines set for the installation of gypsum board, potentially leading to issues over time. The key takeaway is that adhering to the 12-inch requirement promotes a more robust installation, leading to better long-term performance of the finished surfaces.
