Gypsum is the primary raw material used in making plasterboard or drywall — a top choice for interior walls and ceilings. The outer layers of high quality lining paper sandwich the inner substance composed of gypsum plaster and certain additives.
In Australia, where homeowners want sustainable homes, this building material is popular because it’s soundproof, fireproof and water-resistant. You can paint over it or ask a professional to apply plaster. The versatility of gypsum board is well-known throughout the continent. But don’t take just anyone’s word for it. Before you invest on drywall, learn about its properties.
What’s inside the sandwich?
The durability and functionality of a gypsum board depend on the strength of the outer paper linings and the core board. The core itself makes up most of the material.
The gypsum crystals found at the center of the paper sandwich offer better insulation against sound. If you’re concerned about insulating the house, top-of-the line lightweight plasterboard should prove sufficient. The crystals also contain water, which helps in case of a house fire. The water drives off the flames and prevents its spread.
Glass-reinforced gypsum board
You may get specially designed drywall that provides equally outstanding protection against water and fire damage. Glass-reinforced products are available from certain manufacturers in Australia. The addition of glass-fibre layers into the mix, plus specific chemical additives and a plaster finish, makes this a good option.
This type of product suits areas exposed to the elements. Standard boards are not recommended for areas exposed to wetness and humidity, but glass-reinforced products can handle the wind and the rain quite well. That’s how tough and reliable they are.
Even if you’re ready to shop for lightweight plasterboard, don’t rush into the installation. Make sure experts answer your questions about installation and maintenance first.
