G ypsum board, drywall, wallboard, plasterboard, sheetrock – these are just some of the names you can use for plaster ceiling board. It is highly popular as a construction material because of its fireproofing and soundproofing abilities, and its versatility. The other advantages of plaster ceiling board are:

  • It can be installed easily, even without professional help.
  • It is an excellent insulator of heat.
  • It is great at isolating sound so it can be great in bedrooms, classrooms, offices, conference rooms, and function halls.
  • It is durable and economically affordable.
  • It can be used to patch up holes or gaps in your plaster ceiling and as a lath base for your plaster.

Plaster ceiling board is different from other panel products due to the fact that it is made up of materials which you cannot find in other products. Let us give you a closer look at the interior materials of a plaster ceiling board:

Gypsum is the heart, body and soul of a plasterboard. The plaster ceiling board thickness will depend on how much plaster gypsum mixture you pour on the material that will serve as its front part.

There are two ways you can include gypsum in a board: by the traditional way of crushing and processing the gypsum rock, and by using synthetically made gypsum. Either way, the gypsum has to go through the calcining process in which most of the water in the material is removed.

To form the gypsum mixture, plaster ceiling board manufacturers combined it with water and other additives to create a slurry which will then be continuously mixed with paper on a machine that is specific to it. After some time, the paper bonds to the mixture, and they become one, mechanically and chemically speaking.



Paper is a vital material for the entire plasterboard making process for the reason that it is part of the core and the covering of a plaster ceiling board. The good thing about this is that almost no specialty paper is needed for this if you are going to use it on the ceiling of your living room or bedroom. Since every manufacturing company is trying to cut back on their chemical use and waste products, the papers used for this are even recycled ones.

Both sides of a plaster ceiling board are covered with paper – the only difference is that the front part of it is smoother, while the back part is a tad bit rougher or coarser so that adhesives and other materials can stick easier to it.

If you want to change the plaster ceiling board for your bathroom, there is now a green or blue plasterboard available, and it is more suitable for areas which have higher moisture.


Fiberglass Mats

Fiberglass mats are the best substitutes for papers if you want a paperless plasterboard. Although there will technically still be paper on a paperless plaster ceiling board because its core will have the same composition as a regular gypsum board, but its front and back coverings will be fiberglass already.

Fiberglass, unlike paper, does not get moldy easily when it gets wet so it is somewhat better than a paper drywall in a way.
