US: The Gypsum Association has revised its GA-216 Application and Finishing of Gypsum Panel Products technical document. It has been revised in 2018 to fit a three year cycle to coincide with the 2021 code revision cycle and to better align with the Association’s other code-referenced documents, namely GA-600 Fire Resistance and Sound Control Design Manual and GA-253 Application of Gypsum Sheathing. GA-216 is referenced in the International Building Code (and other I-Codes) as well as NFPA 5000 as a standard for the application and installation of gypsum panels.
The 2018 specification provides appropriate installation methods for the various types of gypsum panels. New to the 2018 specification is clarification of language on steel studs and abuse-resistant and impact resistance panel products and updated criteria for panel installation over concrete. Direct adhesion to concrete is no longer acceptable; panels must be installed on framing. Also, GA-223 Gypsum Panel Products, Types, Uses, Sizes, and Standards has been added to the appendix as a reference to ASTM standards and Gypsum Association publications that provide additional information and specifications.
