[PAR] [TLE] Drywall [SEP] Drywall (also known as plasterboard, wallboard, gypsum panel, sheet rock, or gypsum board) is a panel made of calcium sulfate dihydrate (gypsum) with or without additives and normally pressed between a facer and a backer (typically thick sheets of paper).  It is used to make interior walls and ceilings.  The plaster is mixed with fiber (typically paper and/or fibreglass), plasticizer, foaming agent, and various additives that can decrease mildew, increase fire resistance, and lower water absorption. [PAR] [TLE] Dymaxion deployment unit [SEP] A Dymaxion deployment unit (DDU) is a structure designed in 1940 by Buckminster Fuller consisting of a 20-foot circular hut constructed of corrugated steel looking much like a yurt or the top of a metal silo.  The interior was insulated, finished with wallboard, portholes and a door.  The dome-like ceiling has a hole in the top and a cap for ventilation.
