There are different types of drywall based on the activity and installation location. One significant benefit of drywall is the existence of tapered edges on the long ends of drywall sheets, which, when connected, make a shallow recess for drywall tape and joint compound, resulting in an imperceptible finished connection.
Drywall is a type of construction material that you can use to cover the framing on walls and ceilings. It’s a form of gypsum, a common and abundant natural substance (making it an eco-friendly choice).
The gypsum is combined with other components to create a slurry sandwiched between two layers of paper and dried.
The different types of drywall are determined by the paper type and thickness and the chemicals in the slurry.
You’re staring at drywall covering hardwood studs when you look at your walls and ceiling. Of course, the walls and ceilings have been polished, textured, and painted or wallpapered, but the walls and ceilings are drywall.
Furthermore, drywall provides fire resistance and soundproofing for walls and ceilings inside residential and commercial structures.
It’s fastened to the framing structure then taped to disguise the gaps between the drywall panels. Finally, mud is applied to smooth the transition and patch the screw holes.
After the mud has dried, the wall is sanded to a fine finish and textured or painted, depending on the desired look.
In addition, the difference between all the types of drywall is the color of the paper that surrounds them.
Different paper kinds and chemicals to the slurry cause the variances.

1. Regular Drywall
The most popular drywall used in homes and commercial applications is regular drywall, also known as a whiteboard. Regular drywall is plain drywall that hasn’t been enhanced in any way.
However, regular drywall is not inferior to other varieties; it outperforms them, and it simply does not include any extras.
In addition, regular drywall, for example, is naturally fire retardant (the water molecules in the gypsum impede the spread of flames), but it isn’t increased with fire-resistant drywall.
2. Moisture-resistant Drywall
Water damage is unavoidable, and it’s an almost inevitable feature of owning a property. Moisture-resistant drywall has a specific surface coating that reduces the amount of damage caused by moisture.
It’s ideal for usage in bathrooms, kitchens, and any other humidor water-piped environment.
However, in high-water areas like tubs and showers, cement board, such as National Gypsum’s PermaBase cement board, is recommended instead of moisture-resistant drywall.
Greenboard is another name you can call this type of drywall. You can also call this type of drywall indoor tile backer board and cement board.
When looking for moisture-resistant drywall, you may also come across the term blue board because it is a different product type, which is worth mentioning.
3. Mould-resistant Drywall
Mold-resistant drywall is wax-coated for additional moisture protection and thicker paper backing than regular drywall.
It also includes a non-organic fiberglass mesh that keeps mold at bay by removing the source of food (called paperless drywall).
Mold-resistant drywall is commonly seen in bathrooms, kitchens, laundry rooms, and tile supporters. Mold-resistant mud is also available, and it’s crucial to distinguish between mold-resistant and moisture-resistant drywall.
4. Fire-resistant Drywall
In locations such as garages, bedrooms, apartment buildings, other multi-family housing units, and many commercial buildings, fire-resistant (Type X, fireboard, or X board) is required by building codes.
Type X drywall outperforms other types of drywall in terms of fire resistance. However, type C is more resistant than Type X, lasting up to four hours than one hour for Type X.
Furthermore, Non-combustible fibers are used in fire-resistant drywall, and it’s also thicker than the majority of other drywall varieties.
These elements work together to limit the spread of fire, giving people more time to flee and reducing the amount of damage.
5. Soundproof Drywall
While all drywall has some soundproofing capabilities, soundproof drywall contains more wood fiber, gypsum, and polymers than standard drywall to increase the sound transmission class (STC).
Like the Richter scale, STC measures how much noise a material can stop. Soundproof drywall is used when additional soundproofing is required, such as between living quarters and shared walls.
Because it’s denser than traditional drywall, it’s more challenging to work with.
6. Paperless Drywall
Paperless drywall has taken the place of traditional drywall. This form of drywall is wrapped in fiberglass rather than paper, which protects the gypsum board from rot and provides even more mold and mildew resistance.
Although the board’s quality is slightly higher than conventional drywall, some building professionals find it easier to cut. Because paperless drywall includes some subtle textures, a joint compound will be needed to obtain a smooth, clean finish drywall level.
Environmentally friendly drywall alternatives have been created and are still being developed. These products are not only ecologically sustainable in terms of materials and manufacture, but they are also high-quality drywall solutions for your home.
Furthermore, Eco Rock is one of the products available. It’s made up of over 20 distinct industrial wastes repurposed.
These byproducts are combined with fillers and water to make a mold- and termite-resistant drywall.
In addition, environmentally friendly ingredients are used to create EnviroBoard compressed fiber panels. The walls and ceilings of homes and structures are made from solid concrete-like panels made from waste fibers from agriculture, the newspaper industry, and other sources.
8. VOC-absorbing Drywall
VOC-absorbing drywall is a new product that gathers chemicals and other volatile organic compounds and keeps them contained within the drywall, rendering them safe.
These compounds can be found in many building materials and cleaning goods that we use every day. After being painted or covered with light wallcovering, drywall can last up to 75 years.
9. Purple Drywall
Purple drywall has the same benefits as conventional drywall, but it is more moisture and mold-resistant.
It’s suitable for all wall and ceiling applications, and it’s especially well-suited to areas where moisture and mold resistance are sought. This is the one to use if it comes into touch with water.
