Plasterboard is often also referred to as drywall, wallboard or
gypsum board. Unlike other sheet-like building products such as
plywood, hardboard and fiberboard, they have a non-combustible core
and a paper coating. When joints and fixing heads are covered with
joint compound, plasterboard becomes a continuous surface suitable
for most types of interior decoration.
Smooth gypsum boards have an ivory-colored surface and a gray
backing. It is made from building plaster as the main raw material,
to which an appropriate amount of lightweight materials, fiber
reinforcements and additives are mixed and bonded with paper.
It is light, stable and has excellent thermal and sound insulation
properties.
1. Fire resistance
Since gypsum itself is a fire resistant material, gypsum
plasterboard can also be fire resistant for up to four hours. The
reason behind this is the presence of water in gypsum offerings.
When water comes in contact with fire, it starts evaporating. It
helps the board to form a protective layer which helps to prevent
the fire from spreading over a period of time.
2. Non-combustible
When a gypsum board comes in contact with fire, it starts the
process called calcination. Calcination is the process by which the
board dehydrates, helping it to form an additional layer. It makes
the wall non-combustible for several hours and always remains at
room temperature.
3.Damp Proof / Waterproof Gypsum Board
The green appearance is mainly made of building gypsum with an
appropriate amount of fiber reinforcing agent and waterproof
additives.
Suitable for wet and semi exposed areas, with a tileable surface.
Scope of application: kitchen, bathroom, laundry, garage, bathroom,
laundry, humid environment, etc.
4. Acoustic properties
Gypsum board has an inherent degree of acoustic insulation. These
are more effective compared to conventional walls of the same
thickness. This is because they contain sound interruptions and
reduce reverberation.
For example, a plasterboard of around 60 mm is as effective as an
85 mm masonry wall in terms of sound insulation. Users can also
choose to use acoustic gypsum board to further improve performance.
