What is a Gypsum board ?

Gypsum board, also known as drywall, is a technical material name used by manufacturers for a specific type of board with a gypsum core and a paper facing. Gypsum board is the leading building material for ceiling, wall and partition systems in commercial, residential and institutional structures. This material is designed to provide a monolithic surface when fastener heads and joints are covered with a treatment system.

Advantages of Gypsum Board ?

Gypsum boards and ceilings offer a variety of benefits including:

SOUND ISOLATION

Blocking unwanted sound from adjoining areas is an important consideration when designing a building, mainly when considering the activities of individuals in various parts of the building. Gypsum ceilings and wall systems assist in controlling sound transmission.

SIMPLE INSTALLATION

Gypsum board systems are simple to install for a range of reasons. The panels are moderately large when compared to other materials and come in size of of 12.5x6x4 Feet. This means that they will quickly cover large ceiling and wall areas. In addition, gypsum board installations only require several tools for their construction.

DURABILITY

Gypsum board is used to erect strong and high ceilings and walls that provide excellent dimensional durability and stability. Surfaces that are constructed using gypsum board are effortlessly refinished and decorated.

VERSATILITY

Gypsum board pleases a variety of architectural requirements for design. Performance, ease of application, availability and its adaptability to all kinds of decorations combine to making gypsum board unbeaten by any other surfacing material.

ECONOMY

Gypsum boards are readily available and simple to apply. In addition, it is a cost-effective wall and ceiling surfacing material that provides a fire resistant interior. Gypsum boards are generally installed at a much lower labour cost than many other alternative systems.

Types of Gypsum Boards

Drywall White Board

Drywall is normally white on one side and brown on the other side. It is probably the most economical drywall type and comes in different sizes ranging in thickness from 3/8 inches to one inch. This is the most usual type used and is normally available in the market in four by eight feet panels.

Applications:

* It has high resistant power to resist the moisture condition.
* Is also used as a tile backer in limited wetting areas such as a bathroom, water closet and basement walls, kitchens and laundry & utility rooms.

Water-Resistant Gypsum Board

This type comes with a water-resistant gypsum core and water-repellent face paper. It may be used as a base for wall tile in baths, showers, and other areas subject to wetting.

Applications:

* Used as a covering material for interior walls and ceilings in residential and commercial buildings.
* Also, require specific moisture or water-related assemblies.
* Best suited for both ceiling and drywall partitions in wet areas like bathrooms and kitchen.
* Used as a base for external soffits in sheltered positions.

Water-Resistant Gypsum Board

Fire-Resisting Gypsum Board

A Fire-resisting gypsum boards provides good fire protection in buildings due to the unique behavior of the gypsum core when exposed to fire. When a fire-resisting gypsum board protecting building elements that are exposed to fire, the chemically combined water is gradually released in the form of water vapor. This condition is caused in general use if the board or gypsum finish is continuously exposed to a temperature over 49°C.

Applications:

* Suitable for applications in ceilings and drywall where a high level of fire protection is required.

Backing Gypsum Board

It includes a base in multiple layers in construction works, where several layers of gypsum boards are desired for high fire resistance, sound control, and strength in walls. It has grey liner paper on front and back faces and is also available on a backing board with aluminum foil bonded to the back face. The boards come 16 to 48 in wide, 4 to 16 feet long, and ¼ to 1 in thick.

Applications:

* Used for walls and ceiling.
* Gypsum plaster blocks used as partitions and as tiles.
* Used for self-leveling screeds.
* Fibreboard with gypsum
