Gypsum boards, also known as drywall, plasterboard, or wallboard, are panel products consisting of a noncombustible gypsum core sandwiched between paper facings. These versatile building materials are widely used in modern construction for various applications, including wall linings, partitions, sound control, and fire protection.

The last few years have seen a range of meaningful developments in the construction landscape. The influx of technological advancements has helped curate advanced offerings that give several advantages over the traditional processes.
When you build your house or renovate it, it is common to come across people suggesting the use of gypsum plasterboards. Even though not a new finding by any means, it is only in the last few years that it has found increased traction in the construction scenario.
Gypsum boards are useful in building lightweight and durable walls.
Even though we are seeing increased use of synthetic gypsum plasterboards, the traditional ones use dehydrated calcium sulfate and convert it into CaSO4.0.5H20 by heating it.
Once dehydrated, the resulting product is mixed with several additives and water. It is then placed onto cardboard running on a conveyor belt. It soon takes the shape of a needle-like structure that combines to form what we commonly know as gypsum plasterboards.
This article delves into the subject and discusses the types, properties, and applications of gypsum plasterboard.
As per ASTM C11, the gypsum board is 'the general name for a family of sheet products consisting essentially of gypsum.'
Also known as plasterboard or drywall, the gypsum board is a technical name given to a plaster-based wall finish that helps in creating light walls. Even though it is an umbrella term, all of its types use gypsum, a non-combustible core, and paper surface covers them.
Once it goes through a joint treatment system, it can create a monolithic structure, built to last.
Gypsum board sizes
You are likely to find gypsum plasterboards of different sizes in the market. Each of these sizes caters to a different purpose. You must choose the optimum size as it will allow you to minimize cost without compromising on quality.
Here are the different size specification for a gypsum plasterboard that you are likely to find -
¼-inch (0.635 cm)
The ¼-inch gypsum plasterboard is a low-cost structure dedicated for use in ceilings, improving existing walls, curved surfaces, and improving sound control. It mainly finds use in home décor.
3/8-inch (0. cm)
The ' -inch gypsum plasterboard finds usage primarily as a face layer for remodelling or repair purposes. These are applied over wood framing and usually in a double-layer format.
½-inch (1.27 cm)
The ½-inch variant is used primarily in single-layer wall systems. It is excellent for soundproofing and fire protection and is more likely to be found in residential buildings.
5/8-inch (1. cm)
The ' -inch variant is one of the thicker versions. It helps in improving resistance, rigidity, and higher fire resistance. These characteristics make them excellent for single-layer and double-layer walls.
¾-inch (1.905 cm) and 1-inch (2.54 cm)
The ¾-inch and the 1-inch variant are used for creating shaft walls, partitions, corridor ceilings, and similar purposes. These are the thickest gypsum plasterboard available and offer the highest resistance.
Easily manageable
Drywalls do not command separate finishing, i.e., you can apply them directly over any base, such as AAC blocks, solid or hollow blocks, bricks, and plasterboards. It is also easier to apply and level them.
Eliminates curing time
Unlike cement and water combination, the new-age boards do not require curing time. It helps you save time and water during the construction phase.
Superior finish
Drywall offers perfectly aligned, levelled, smooth surfaces that are superior to the traditional cement-water combination, which requires post-processing for the same.
Enhances setting time
A cement-based plaster must dry properly for a few days before you can carry on the painting process. Drywall sets within half an hour, enabling you to begin painting within three days of application.
Excellent durability

The application of gypsum plasterboard reduces the dead load on the structure and ensures a highly durable structure once it dries.
Low supervision requirement
The traditional plaster requires mixing cement, sand, and water in proper proportions. It means that there is a constant need for supervision to ensure that the mix is usable. But gypsum plasterboard does not require continual checks and reduces the time spent in supervision.
Fire and sound resistance
The drywall structure offers superior resistance against fire and sound, making it a better alternative compared to traditional plaster.
It was in the year that people experienced the use of gypsum as a building material. The American Augustine Sackett developed a machine capable of producing drywalls that had paper and gypsum in between.
Today, we use gypsum plasterboard for both residential and non-residential buildings. It includes using them for construction and refurbishing purposes. The ability of it to be highly ductile and also have a plethora of useful characteristics has been instrumental in its growing popularity.
In Europe, over million square meters of interior surfaces get gypsum-based covering (blocks or plasterboard).
What are gypsum plasterboard ceilings?
It is a false one made of gypsum plasterboards. These are easy to install, clean, and maintain.
Is the gypsum plasterboard good for the ceiling?
False gypsum board ceilings are long-lasting. In normal circumstances, these will last over 20 years with minimum maintenance requirements.
What is the standard size of the gypsum plasterboard?
Usually, the length lies between mm to mm. If you need a customized one, you can order one with different dimensions.
Is the gypsum plasterboard waterproof?
Gypsum plasterboards also come in a waterproof variant. Even otherwise, these do not intake too much water and offer a certain level of water resistance inherently.
Can the gypsum plasterboard be painted?
Users can paint the surfaces after applying a coating of a drywall primer. The primer would help level the surface and ensure smooth paint application.
Can we use a gypsum plasterboard in a bathroom?
The regular variant is not a good fit for side bathroom walls. But green drywall, the mould-resistant one, or the purple board, can be used for locations that are in constant contact with water, such as bathrooms and kitchens.
How do you maintain the gypsum plasterboard?
Gypsum plasterboard is an excellent option for indoor purposes. It requires no additional maintenance. You can use the regular rug or broom to clean it. Unless you are using the waterproof drywall, make sure that you don't use water for cleaning it.
Is gypsum plasterboard bad for health?
No. There are no health-related hazards linked with its application. It is not classified as 'dangerous' as per EU CLP regulations. If you somehow ingest gypsum, drink plenty of water after washing your mouth thoroughly.
What is the average moisture level in the gypsum plasterboard?
In usual circumstances, moisture content of 5-12% is considered best. If it is over 12%, it means that you will have to replace it.
What is a purple board?
Purple board or purple gypsum board is a modified variant offering better resistance against moisture, mold, and mildew. It is effective for places prone to high moisture content. A purple board comprises two thin sheets of plasterboard with a thin elastomer centre in between. It also offers better soundproofing.
What is the right drywall thickness for my ceiling?
If you are using drywall for ceilings, 5/8-inch is the most appropriate size. These reduce sagging chances while being lightweight and offering good heat resistance.
Traditionally, gypsum plasterboard is costlier than cement-based plaster. But they offer superior resistance making them a more viable option for long-term usage. The availability of synthetic gypsum created as a by-product of industrial processing has helped keep the cost in check while offering the same characteristics.
It has also allowed better usage of waste, helping to keep the environment clean. Gypsum plasterboard is also considered easy to recycle and is one of the rarest examples of closed-loop recycling, i.e., using the waste to make the same product multiple times over. It is the reason these are considered 'green' for the environment.
