Plasterboard

What is Plasterboard?

Plasterboard is one of the most versatile and popular building materials in use today. You will find plasterboard in almost every residential as well as commercial building project in almost every part of the world. Plasterboard is an amazingly simple material, composed of an inside layer of gypsum and covered by outer layers of paper. Different configurations of plasterboard are achieved by the introduction of specific additives to the gypsum and through the use of different strengths and types of outer paper layers. Where is Plasterboard Used? By far, the most common applications for plasterboard, as it is sometimes called- sheetrock- is as the primary cover over wood studs in the walls and ceilings of buildings. It is relatively quick and easy to install and offers a wide range of appealing characteristics that contractors prefer:
  • Fire Resistant – The primary component of plasterboard, gypsum, is composed of crystals that hold small amounts of water that hold down the temperatures in a fire situation. This means that the spread of a fire can be retarded between rooms that are separated by walls made of plasterboard.
  • Sound Resistant – Plasterboard is an industry leader when it comes to sound deadening or acoustic insulating properties. Gypsum is a very good sound absorbing material and there are many types of plasterboard that are specifically designed to absorb sounds through a specially designed inner core.
  • Water Resistant - For areas that are exposed to moisture on a regular basis, there are specially made types of plasterboard that have a water resistant coating and silicate additives in the gypsum core that will repel or resist moisture better than standard plasterboard. This water resistant plasterboard is typically used in entryways, wash rooms and kitchen areas. 

 

Plasterboard Standard Configuration  Plasterboard is available with two types of edge configurations. If you are planning to overlay a textured finish to your walls or ceilings, we would recommend the square edges option. For most other applications, the tapered edge is the preferred solution. Lengths are available up to 6 meters with thicknesses of 10 or 13 mm.

 

Tips on Plasterboard Installation  Once a plasterboard wall has been installed, taped, and sanded, you should be able to apply paint as soon as the joints have had a chance to dry. If you are going to apply a wallpaper, it is best to plan ahead and seal the plasterboard surface with a drywall sealer. You will be glad you did this extra step when it is time to remove the old or unwanted wallpaper.
