Definition

Noun: A building material consisting of a rigid panel made from a core of gypsum plaster that is sandwiched between and bonded to thick sheets of paper or fiberboard. It is primarily used to construct or cover interior walls and ceilings, serving as a faster and cleaner alternative to traditional lath and plaster construction.

It refers to the material in general or to specific sheets or panels of the material. * Plasterboard is a common material for building interior walls. * We need to buy ten more sheets of plasterboard to finish the ceiling. * The wall was made of plasterboard.
