Gypsum board, also known as drywall or drywall partitioning, is a wall panel made out of compressed gypsum, coated in durable paper and used for interior walls and ceilings. It has been utilized as one of the primary methods for wall construction in many houses, offices, schools and retail outlets. The reason for this being that you can get the job done quickly and cost effectively. Supertec supplies gypsum board from a variety of suppliers both local and international such as Marley Siniat, Saint Goban, Gyproc & Pelican Jumbo.

Application Of Gypsum Board
Vertical aluminum structures or frames are used as the skeletal structure that provides support for these sheets of gypsum board. These sheets are attached to the framing by either screws or nails, and finally joined together using a specific tape and compound which leaves an even and smooth crease less surface that is finished off with a coat of paint. This is also known as drywall partitioning.
In the case of Gypsum Board, used for ceilings, the boards would also be attached to the wooden ceiling beams with screws or nails and finished off.
The panels consist of a mineral gypsum, or hydrous calcium sulfate with its main ingredient in plaster of paris, as well as a component of cement.
Gypsum Board Has A High Fire Resistance Level
Gypsum board is an excellent fire-resistant building material. Where fire resistance classifications are required, the use of Gypsum board offers the ideal solution.
Its non-combustible core contains nearly 21% chemically combined water, which, under high heat, slowly escapes as steam. Steam does not exceed 100 degrees C under normal atmospheric pressure; it therefore is very effective minimizing the transfer of heat and the spread of fire. Even once all the water has been released from its core, gypsum board continues to serve as a heat-insulating barrier.
Gypsum is found and mined across the world with large deposits found in various countries. In addition to this natural form, a synthetic form of gypsum is produced as a byproduct of coal-fired power plants.
How Gypsum Board Is Manufactured
Manufacturing gypsum board begins with the process of grinding and mixing the Gypsum with starch to help with bonding. Other trace ingredients might be added to the mix at this point depending on the nature of board required. Just enough water is added to create mixture of the right consistency. The wet slurry gypsum mix is then sandwiched between two heavy sheets of paper and kiln dried to make the board rigid. The large sheets of wallboard or panels are then cut into the desired standard sizes.
The development of this type of wallboard began as early as 1917, but it did not become popular for residential home use until after World War II.
Mortar and brick walls take a great deal of time to build, and in the past could generally only be done by professionals. Construction using gypsum board is much more efficient and does not require the specialized labor that plaster walls sometimes do.
Other benefits of Gypsum Board include:
• Sound Insulation
• Limits the spread of fire.
• It’s relatively quick and easy to install Gypsum Board Drywalling
• Gypsum board is strong, producing high quality walls and ceilings that offer excellent dimensional stability and durability
• Versatility – Gypsum board satisfies a wide range of architectural designs.
