Plasterboard, also known as drywall, wallboard, etc., come in different varieties. Did you know that? Very few non-professionals actually know this fact. While pros use a variety of plasterboards for GIB stopping in Auckland, there are a few types that are actually DIY-friendly. So, if you have planned to take up a few home improvement projects, here are 5 plasterboard types you should know about.
Regular gray plasterboard
All plasterboards have gypsum as the main element, which is sandwiched between paper layers—brown in the back and colored paper on the face. In regular plasterboard, which is the most common type most homeowners are aware of, the face paper is gray. These can be used anywhere in the house and come in a variety of sizes, the most common one being 4-foot by 8-foot.
Mold-resistant plasterboards have green face paper and are a great option if you have mold and mildew problems in the house. These are most commonly used in places with the most moisture exposure like the bathroom. To make the best out of the plasterboard, use a mold-resistant joint compound. But before you jump the gun to get this board, consider your cost limitations because these cost about 20% more than regular ones.
Like the green plasterboard, moisture-resistant plasterboard, which is purple-colored, is effective against mold, mildew, and moisture. In tandem, it also resists scratches, scuffs, and dents. As such, the board is a great choice for high-traffic areas. Like the mold-resistant one, this plasterboard too is more expensive (up to 30%) than the regular board.
While all types of plasterboards are fire-resistant, there is a special type that has better fire ratings called Type X. This board is thicker and is made of glass fiber-mixed gypsum, which increases its resistance to fire. They are not fireproof but have a one-hour fire rating. The fire-resistant plasterboard is usually required by building codes for walls shared with garages.
Perhaps the costliest plasterboard type on this list is the sound-dampening board, costing about 400% more than the regular ones. These are of the same thickness as the regular plasterboards (½ inch) but have layers. Between the face and back papers, you have a ¼ inch layer of gypsum, followed by a membrane, and another ¼ inch gypsum layer. This layered effect increases the Sound Transmission Class (STC).
Plasterboards come in different varieties, each with its own applications and advantages. While you can always go for the regular ones, for specialized needs like mold resistance and sound dampening, you need a specific kind of plasterboard. When you learn the difference between each type, you can easily build the walls you need for your house.
