What is a Gyprock board?

A Gyprock board is basically a plasterboard with just a different name! Gypsum, being the major ingredient in the making of a plasterboard, and Gyprock being the brand, can pretty much explain the confusion caused here.

The primary ingredient that goes into plasterboards is gypsum, which as a fact contains 2 molecules of water and 1 molecule of calcium sulphate. By weight, when talking in chemistry terms, contains 21% water, but in actuality it comprises more than 50% of water. This water is majorly found in crystalline form which gives it a powdery look when ground, but the water is there for sure!

Unlike ice, this form of water doesn’t turn liquid upon coming in contact with the heat. Instead it turns into vapour upon reaching around 100 degrees celsius. Gypsum is used at various places in our everyday life and you would be shocked to know about some places where this material is used.

How are Plasterboards made?

After heating 75% of the water from the mixture, you get a powder known as POP or Plaster Of Paris. This is the prime ingredient that goes into making a Plasterboard which then reaches gyprock Plasterboard suppliers before adorning your home. Almost millions of tonnes of gypsum are mined globally every year, and a major chunk of this yearly excavation is used in the making of plasterboards which are then used around the world in various builds.

The other major ingredient used in this is paper!
2 Sheets of paper are required to create a sensible plasterboard which will then be able to take the impacts and the weight of the structure.

A Gyprock plasterboard mixture consists of POP (Plaster Of Paris), Asphalt emulsion or wax emulsion, & a foaming agent. While these are mixed together, air is passed through to create a considerable tension between the materials to form aerated spaces or pockets.

The mixture mentioned above is poured onto a sheet of paper with the top layer closely following from above. This sheet of paper is then placed on top of the slurry which is then pressurised into the shape of a general plasterboard and is later on dried out in an oven.

Here the boards are heated to a whopping 260 degrees celsius which gradually reduces over a period of 30-45 mins to create the perfect conditions for the crystalline moisture to stay intact in the board.


The finished plasterboards arrive at your gyprock plasterboard suppliers warehouse and later on, reach your building in no time. Plasterboards are used in almost every build and undergo a somewhat tedious process before looking as beautiful as your wall.
