A type of wallboard with a plaster core sandwiched between two layers of paper. Gypsum board was patented in 1894 by Augustine Sackett. By World War I, production methods for gypsum board were standardized and it was widely used for the construction of military barracks. Over time, various fillers were added to decrease weight (pumice, bubbles, etc.), to increase fire resistance (asbestos) and to increase crack resistance (wood and mineral fibers). Dextrin, or starch, is typically used as a binder. Gypsum board, also called drywall, is fire resistant, dimensionally stable and inexpensive. During World War II, gypsum board completely replaced the use of metal lath/plaster walls in new construction because the prefabricated boards were faster to assemble and because the use of steel was restricted. Currently, it has widespread use in the construction of interior walls and ceilings.
