Introduction
Gypsum plasterboards are composed of a plaster core encased in, and firmly bonded to paper liners to form flat
rectangular boards. This composition allows them properties which makegypsum plasterboards particularly suitable
for use in situation where fire protection, sound and thermal insulation are required.
Gypsum plasterboards may be fixed by various methods e.g. nailing, screwing or sticking with gypsum based or
other adhesives. They may also be inserted in a suspended ceiling system.
Gypsum plasterboards are selected for use according to their type, size, thickness and edge profile. The boards
may be used for example to provide dry lining finishes to walls, to fixed and suspended ceilings, to partitions, or as
cladding to structural columns and beams. Other uses may be for flooring and sheathing application.
Diagrams 1 and 2 show the relationship between this standard and the package of standards prepared to support
the families of gypsum and ancillary products.
