Technical Topical Papers - Gypsum Association

Gypsum is a mineral consisting primarily of fully hydrated calcium sulfate. Like most minerals and rocks, gypsum is strongest in compression. When attached to ceiling framing, gypsum wallboard acts like a simply supported beam between supports. All other factors being equal, the strength of gypsum board is directly proportional to thicknes(6,7).
