LUKE: The ceiling’s falling in. I’ve got customers eating drywall here.
Drywall is a North American term for the building material which is elsewhere known as plasterboard, gyprock, or gypsum board – panels made from gypsum sandwiched between paper, used in the construction of interior walls and ceilings. The plaster is mixed with fibres and various additives that reduce mildew, flammability, and water absorption.
