The regular or white board drywall is the most common type used in both residential and commercial buildings. In regular drywall, the gypsum is placed between two layers of paper sheets. The paper on the back of the panel is usually brown while the other one is grey in color.
And the whole design is simple with one white color and no ceiling and wall texture. A regular drywall board can be used throughout a house and is available in a variety of dimensions. The most common size is a 4×8 foot sheet.
Another commonly found type of drywall sheet is a green board. This is a more mold-resistant type used in rooms where moisture can be an issue – for example in the kitchen, bathroom, attic, and basement.
To maximize mold resistance, I recommend using drywall mud on the green board. This type of drywall generally costs 20% more than white or regular drywall, but it is well worth considering in moisture-prone rooms.
Another highly moisture-resistant drywall that’s used for veneer plastering is the blue board. This drywall board has high mold and water resistance and is often used in basements and bathrooms. In addition to its unique water absorption qualities, blue board helps reduce noise, thus making it an ideal choice for converted basements and other habitable spaces in the home.
Purple boards resist mold, mildew, and moisture. They are also scratch and dent resistant, thus making them a good choice for high-traffic areas. These drywall panels are around 30% more expensive than white boards, offering superior moisture and mold resistant qualities that regular boards lack in.
Purple boards can be used with all ceiling and wall applications wherever enhanced mold and moisture resistance is needed. Being only 5/16 inches thick, these boards are super easy to install and repair.
While all types of drywall are fire-resistant, there is a special type that has higher ratings than others. The type X drywall consists of several thickness layers to achieve a higher fire rating.
The type X drywall is more difficult to cut and work with when compared to regular boards. The sheets are enclosed in the ivory-colored paper that comes with a strong liner back.
They are usually used in apartments and garages and made from special non-combustible fibers. The thickness of these boards is 5/8 inches with excellent soundproofing characteristics.
To make a type X board, the 5/8 inch thick gypsum panel must achieve a minimum of 1-hour fire-resistance rating or 3 hours of fire-resistance rating for a half-inch board in a single layer.
The type C drywall is also the same thickness as the type X. The difference between the two is that more glass fibers are used in type C. In addition, the gypsum core of type C has anti-shrinkage properties, which makes it an improved version of type X.
Soundproof drywall is exactly the same thickness as a white board, but it is layered rather than flat. There is a quarter-inch layer of gypsum in between the front and back paper followed by a membrane and a further layer of gypsum of the same size. These layers reduce noise transmission from one room to another.
To install soundproof drywall boards, no special equipment or tools are required. These panels are highly recommended for home theaters, but they do cost significantly more than regular drywall (up to 300% more!).
Paperless drywall consists of sandwiched gypsum between fiberglass instead of paper. This type of drywall is highly resistant to moisture, mildew, and mold and is mostly used in bathrooms.
Although cement board isn't drywall it still plays an important roll for doing certain walls in a home. Cement board is highly resistant to water and mold and is usually used in shower and bath areas. The cement board is reinforced with fibers that make it very rigid, making it a stable base for installing tiles or other stone. When hanging wet walls, or doing damp areas this is what you'll most likely want to use.
