This term includes gypsum board, glass mat gypsum panels, abuseresistant, and impactresistant gypsum panels and gypsum shaftliner panels. Refer to GA235, Gypsum Board Typical Mechanical and Physical Properties, for more information on characteristics, properties and performance. GA235 is one of many free downloads in the GA Bookstore section.
Gypsum contains nearly 50 percent water, which accounts for gypsum plaster''s fire resistance. In gypsum molecules, water forms crystals that do not melt like ice, but only escape at high temperatures. It is this high concentration of water in gypsum that accounts for its fire resistance.
