Gypsum boards also referred to as plasterboards, are hydrated calcium sulphate boards made in factories and used for false ceilings. These boards, which come in 9, 12, and 15 mm thicknesses, are often produced in sizes of 4 x 6 feet, 4 x 8 feet, and 4 x 10 feet. They are simple to install; simply cut to the correct dimensions, and then fitted to a metal framework hanging from the ceiling.
There are fewer joints since gypsum plasterboard is available in larger sheets than POP sheets. The joints are finished with a jointing compound. Gypsum plasterboard installation is a speedier, cleaner, more practical, and safer approach because less trash and dust are created during the process. Gypsum plasterboard is more durable than POP. One of the main reasons gypsum boards are utilised for artificial ceilings is their hydrophobic properties. Gypsum boards are used in office interiors as partition walls and false ceilings. Another advantage is that its composition can easily resist termite attacks and formation in moulds inside the panel. These are primarily used in places with a central air-conditioning system and can be used in kitchens and bathrooms. The natural colours of gypsum include white, yellow, red, brown, and grey. False ceiling boards made of gypsum can be finished with laminate, wallpaper, and textures.
Different types of gypsum boards and their applications
Regular Gypsum board
Typically, one side of this kind of gypsum board is white and the other is brown. The Gypsum board that is most frequently utilised in settings without particular specifications is this kind. Gypsum board is naturally fire resistant, although there are no added components that increase its fire resistance. General gypsum board panels typically come in 4 by 8-foot panels with a thickness range of 3/8 to 1 inch.
Moisture Resistant Gypsum Board
Gypsum board that is moisture resistant, often known as “green boards,” has a green covering that makes them more moisture resistant than conventional gypsum board. Be aware that while more expensive than standard boards, this is not completely watertight. Never install these in locations where there is constant water contact because doing so may cause the boards to slowly disintegrate. These boards are frequently used in basement walls, kitchen walls, and laundry room walls.
A unique kind of board is used for veneer plastering, often known as blue board drywall or plaster baseboard. Its surface paper’s excellent absorption properties allow it to absorb plaster-like glue with ease. It is perfect for an all-purpose partition board because of its high water and mould-resistant properties. Blue boards perform well in high moisture locations like bathrooms and kitchens but should not be used for dirt, paint, or tape. Additionally, when utilised as room partitions, this kind of gypsum board significantly decreases noise.
Paperless Gypsum Board
Over the past few years, paperless gypsum boards have replaced conventional ones made of gypsum. This type of board’s fiberglass coating, used in place of paper, substantially increases its longevity and resistance to mould and mildew. It is considerably simpler to cut forms to various shapes and sizes even though it is more robust than conventional boards. Be aware that to achieve a smooth and flat surface, paperless gypsum boards need to have their modest inherent texture smoothed down.
Improved Moisture Resistant Gypsum Board
Purple gypsum boards have a better moisture resistance property than green gypsum boards. It is perfect for use for wall and ceiling applications, especially in damp spaces like bathrooms and kitchens, because of its exceptional moisture and mould resistance. If the area where the board will be located is regularly exposed to water, think about utilising this type of board.
Type X Gypsum Board
Type X gypsum board, also known as fire-resistant drywall, is the greatest option for superior fire-retardant building material. Although ordinary drywall is often fire resistant, Type X is made of special non-combustible fibres that make it more fire resistant than ordinary drywall. It is more difficult to cut and shape due to its more protective and sturdy nature. These boards can also be used to block out noise. They can also be installed in layers for a better fire rating.
Sound-proof Gypsum Boards
Gypsum boards generally universally provide some measure of soundproofing, but sound-proof drywall specialises in virtually complete sound absorption inside the room. This type of gypsum board is denser and more difficult to cut than conventional boards because it is made of laminated layers of wood fibres, polymers, and gypsum. Its strong soundproofing qualities make it perfect for music or entertainment spaces where loud noises need to be adequately muffled.
Disadvantages of Gypsum board as a false ceiling material
- The ceiling needs to be taken down for any repairs.
- With time, the gypsum board joints may begin to exhibit signs of cracking. The smallest movement in the false ceiling owing to ceiling repairs, the drilling of holes for light or fan fittings, or where the ceiling meets adjacent walls can also result in cracks.
- It may result in fungal growth or warping if moisture penetrates the gypsum ceiling from leaking roofs or air conditioning drain lines. Choose only high-quality gypsum board brands like India Gypsum, which permit the least amount of water retention, as a precaution.
