All You Need To Know About The Different Types Of Plasterboards


Choosing the correct plasterboard is extremely vital in maintaining a proper interior design as well as safety. Furthermore, if you want to enhance certain qualities of your walls & ceilings, such as being fire-resistance, moisture-repellent or sound-insulating, then making the right decision becomes all the more significant. 

Therefore, to help you know more about plasterboards, we’re going to discuss the same in this extensive guide. We’ll go through the various types and their relevant uses so that in case you decide you opt for one in the future, there will be no issues when making your final decision.

Definition Of A Plasterboard

According to a professional service provider offering ceiling repairs in Sydney, plasterboard can be defined as a material that is used in the making of interior walls & ceilings. It’s made up of gypsum or calcium sulphate dihydrate. The early form of plasterboard was first invented during the 1880s. But, it was only during the 1910s, when it had started to become a popular construction material.

With the help of a plasterboard and plasterboard tape, a good finish can be obtained on any type of interior wall. Moreover, it should be known that plasterboard tends to form one of the easiest ways to apply plaster to a wall. 

The Various Types Of Plasterboards

  • Water-Resistant Plasterboard

Otherwise known as moisture-resistant plasterboards, these are mainly used inside bathrooms & kitchens, where there’s a lot of moisture. 

These plasterboards contain certain additives that prevent the onset or accumulation of moisture on the walls. As a result, you can expect your walls (and ceilings) to stay dry without any risks of dampness and eventual mould infestation. However, if you install the incorrect plasterboard type inside a kitchen or a bathroom, then it can lead to water damage on the walls, leading to deterioration & weakening of the walls (and ceilings).

  • Insulated Plasterboard

Similar to water-resistant plasterboards, but instead of resisting water molecules, these plasterboards trap the heat inside the walls & ceilings of your home interiors. These plasterboards are also known as thermal plasterboards because they contain a thermal insulation board affixed at the back of the plasterboard. 

Both the traditional plasterboard and the insulating board combine to form a singular sheet offering the highest form of indoor insulation. Proper insulation inside your home is essential in lowering your monthly energy bills. 

  • Fire-Resistant Plasterboard

The job of fire-resistant plasterboard is to resist fire from spreading inside your home – from one room to another. These plasterboards have multiple types depending upon their effectiveness. 

Fire-resistant plasterboards generally have a minimum resistance time between 1/2 to 2 hours. Various additives & glass fibres are used in the manufacturing process.

  • Acoustic Plasterboard

Otherwise known as sound-dampening or soundproof plasterboards, acoustic plasterboards are mainly designed to lower the transmission of sound from one room to another. These plasterboards tend to have the highest density out of all the available plasterboards because their sole job is to contain noise within a specified area.

Besides density, they also have a large thickness around 12.5 MM. The function of acoustic plasterboards can be further enhanced by adding materials such as fibreglass or mineral wool.
