Question: I am installing a typical gypsum panel vertically, not in a fire-rated system. In this case, since the wall isn’t fire-rated, do the joints at the ends of the panels still need to be staggered?

Answer: The short answer is yes. Per GA-216-2024 Application and Finishing of Gypsum Panel Products Section 4.6.7 on single-layer application and Section 4.6.8 and its subsections on multi-layer applications, the joints at the ends of the panels must be staggered, regardless of whether the application is horizontal or vertical.What Are the Benefits of Staggering End Joints?

•    Improves Structural Strength and Integrity: A staggered pattern helps distribute stress more evenly across the wall. Staggering the joints at the ends of the panels enhances the wall's overall stability and reduces the risk of cracks developing over time.

•    Better Finish: Staggering reduces the likelihood of visible joint lines after taping, application of compound, sanding, and painting, resulting in a smoother surface.What Are the Best Practices for Vertical Installations?

For single-layer systems, stagger end joints and alternate their position on opposite sides of the partition.

For multi-layer systems, stagger end joints between layers. The base-layer joints on one side should be staggered from those on the other side. If layers are applied in the same direction, offset vertical joints by at least one cavity space.

For more specific requirements, referencing GA-600-2024 Fire Resistance and Sound Control Design Manual or GA-216-2024 directly is best practice. Earlier versions of these two publications are available to download free of charge in the Gypsum Association’s bookstore.
