Q.1119: What is Plasterboard? Is Plasterboard same as Drywall?
Ans. “Plasterboard” is
basically an inner layer of gypsum sandwiched between two outer layers of lining
paper. The finished plaster board gets different properties by variation of
various additives in the gypsum layer and varying the weight and strength of the
lining paper. The liner on the ivory face is specially designed for plastering
plaster. Paper liners are generally made from recycled paper. Currently, paper
account for two-thirds of the global demand while other plasterboards have a one-third share of the market. Plaster board can also be called drywall.
