Definition: Large, flat sheets of pressed gypsum that compose the inner walls of most residential buildings. Sheets come in 4'x8' and 4'x10' sizes and 3/8" or 1/2" thick. The long sides of the boards are curved inward to accept application of drywall joint compound, or "mud." In the past, sheets were nailed to studs but today are affixed by means of drywall screws.
Drywall is one of the most fundamental building materials used in houses today.
