12.5mm Gypsum Reinforced Drywall Board 1220x2440 Plaster Board For Ceiling
Description of 12.5mm Plasterboard
12.5mm drywall is often referred to as drywall, wallboard, or drywall. It differs from other panel types of building products such as plywood, cardboard and fiberboard because of its non-combustible core and paper face. When the connection and fastener heads are covered by a joint composite system, plaster wallboard creates a continuous surface suitable for most types of upholstery.
The plain drywall has an ivory surface and a grey back. It is mainly made of construction gypsum with a moderate amount of lightweight materials, fiber reinforcement and additives, glued to the paper.
It has the characteristics of light weight, high strength, heat insulation and sound insulation.
Applicable scope: office building, restaurant, residence, hospital, theatre, school, factory.
Features of 12.5mm Plasterboard
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. 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.
4. Thermal performance
Gypsum boards contain water of crystallization. They also contain cavities that allow the user to achieve the right balance between humidity and temperature. If you add fiberglass, it will further prevent fire as the fiberglass helps maintain the integrity of the board. The additional insulation acts as a vapor barrier and helps control humidity in the room.
