The term gypsum panel products is used throughout GA-216 and is defined in ASTM C11, Standard Terminology Relating to Gypsum and Related Building Materials and Systems as the general name for a family of sheet products consisting essentially of gypsum. Gypsum board is defined in ASTM C11 as, “the generic name for a family of sheet products consisting of a noncombustible core primarily of gypsum with paper surfacing.” Gypsum boards make up the predominant portion of the family of materials identified as gypsum panels.
Gypsum panel products can be faced with paper or another material, or they may be unfaced. Gypsum board, glass mat panels and sheathing products, and unfaced gypsum-based sheet products are all considered to be gypsum panel products.
