Different Types of Drywall Explained

Not sure which type of drywall you need? There are quite a few different types of drywall boards you can pick up at your local supplier, but do you know why purple is better than green? Do you know when you need to use a cement board? In this article, we will go over each type of board and explain what each one is used for. 

White Board Drywall (Regular)

Whiteboard drywall is the most common type, as it can be used throughout a house or commercial building. These boards are usually 4×8 feet and consist of gypsum, which is placed between two layers of paper sheets. One side is usually brown, while the other one is grey without any texture. 

Green Board Drywall

what greenboard drywall is used for

Green board is commonly found in kitchens, bathrooms, basements, attics, and other places where moisture can become an issue. This type of drywall is moisture resistant and used to be thought of as “water-resistant” until that term became outdated. 

The reason why it’s not used everywhere is that it generally costs 20% more than regular drywall. Purple board is recommended over green as green boards are not mold-resistant.

Blue Board Drywall

Blue board is another mold-resistant type of drywall, mainly used for veneer plastering, but also known for its excellent noise-reducing properties. Since blue boards feature a more absorbent paper layer, they bond well with a veneer plaster coating. 

Purple Board Drywall

Purple boards are 30% more expensive than your regular whiteboards, but they offer superior moisture, mold, and mildew resistance. These boards can be purchased in ⅝ or ½ thickness, and they are designed for use in any room where mold and moisture are a concern – including ceilings. Purple board drywall is also excellent for its scratch and dent resistance, making them useful for high-traffic areas of a building. 

Type X Drywall

Type X drywall is thick, and much more fire-resistant than the other types of drywall mentioned in this article. These drywall boards consist of several thick layers to get a higher fire rating. 

This drywall is more expensive and more difficult to work with and cut. It’s typically more expensive to have type X drywall installed due to the extra costs and time spent working with the material. It’s heavier and harder to cut. 

Type X drywall can usually be found in apartment buildings, office buildings, and anywhere a higher fire rating is required. 

Type C Drywall

Both Type X and Type C drywall boards are meant to offer superior fire resistance compared to the other boards mentioned. However, Type C is often referred to as the enhanced version of X, as its gypsum panels have an enhanced formulation that performs better. These boards also have anti-shrinkage properties and come in ⅝ or ½ inch thickness.

Soundproof Drywall

If you’re looking to build a home theater, recording studio, podcast room, or any other place that needs to be soundproof, then you will want soundproof boards installed. These drywall boards are built to reduce noise transmission from one room to the next and feature multiple layers to achieve this goal. 

Installation is the same, but results may vary depending on the brand you buy. QuietRock was the first one to hit the market, but CertainTeed and National Gypsum also offer soundproof drywall boards. Even though there is no difference when it comes to installing these boards, it does cost a lot more to soundproof a room because soundproof panels can be as much as 400% higher than regular drywall. 

Paperless / Fiberglass Board

Paperless drywall offers fiberglass in place of the paper layers normally found on drywall boards. Fiberglass boards are highly resistant to mold, mildew, and moisture. These are often used in bathrooms. 

Cement Board

Typically used for shower and bath areas, cement boards offer superior resistance to water and mold. Since these boards are reinforced with fibers to make them very rigid, they are a perfect base for installing tile over. For example, you could use a cement board for your walk-in tiled shower. 

Conclusion

If you just want to patch a wall in your home and you weren’t sure what type of drywall to use, you should now have an understanding of what will work for your situation. If it’s in a bathroom, you will want to use the purple boards. If it’s just a random wall in your bedroom, you can use regular drywall. Consider what you already have installed, and make sure you match the thickness of your existing drywall. 

SheetRock and Durock are both the leading brands in the industry, but there are other brands and their colors might not mean the same exact thing. Make sure to read about the product you’re buying to make sure it’s best for your project.
