Every three years, in alignment with the building code cycle, the Gypsum Association issues new editions of the Association’s three code-referenced publications: GA-600 Fire Resistance and Sound Control Design Manual, GA-216 Application and Finishing of Gypsum Panel Products, and GA-253 Application of Gypsum Sheathing.
Passive fire protection is an essential aspect of gypsum construction. Gypsum firewalls of various types (shaft walls, simple partitions, etc.) prevent fire from spreading without relying on mechanical means of control, such as sprinkling.
