Types of Drywall

List of the most common used drywall and their applications.

By

Which drywall type is the one right for you? There are many types of drywall depending on the activity and the place where it will be installed. One important detail that drywall offers is that the presence of tapered edges on the long edges of drywall sheets. These tapered edges when joined together will form a shallow recess for drywall tap and joint compound that allows for invisible finished joints. Let’s see which is the most common drywall used.

1. Regular Drywall or White Board

Regular drywall is normally white on one side and brown on the other side. It probably is the most economic drywall type and comes in different sizes ranging in thickness between 3/8 inch to 1 inch.

2. Green Board Drywall

Green board drywall is also known as moisture resistant drywall. It has a green covering that makes it more resistant to moisture than regular drywall. It is somewhat more expensive that regular drywall. It is not waterproof, so don’t use it if it’s going to be in contact with water. Also used as tile backer in limited wet areas, e.g., bathroom and basement walls, plus kitchens, and laundry and utility room

3. Blue Board Drywall

Blue board drywall is also known as plaster base board. Blue board is used for veneer plastering, and the surface paper has special absorption qualities. It has a high water and mold resistance and there are fewer steps involved in veneer plastering. Blue board drywall is not made for mud, tape and paint. It works well in bathrooms or places with a lot of moisture. Additionally, this type of board helps reduce noise and offers low emissions.

4. Paperless Drywall

Paperless drywall has been replacing paper drywall over the last years. This type of drywall is covered with fiberglass instead of paper, which protects the gypsum board from rot and offer even greater resistance to mold and mildew. The quality of the board is a little tougher than regular drywall. Some people find it easier to cut. Remember that you need to take extra steps when dealing with fiberglass materials. Paperless drywall has some slightly textures that will require applying joint compound to achieve a smooth clean finish drywall level.

5. Purple Drywall

Purple drywall is an improved moisture resistant product that offers the same advantages of regular drywall, but only with superior moisture and mold resistant characteristics. It might be installed in all wall and ceiling applications and is ideally suited where enhanced moisture and mold resistance is desired.

6. Type X Drywall

This one is the so called fire-resistant drywall. Several thicknesses can be used in layers to achieve higher fire rating. It is harder to cut and work than regular drywall and normally is used in garages, rooms and apartment buildings, as it is required by several building codes. Type X drywall is made with special noncombustible fibers. It normally comes in 5/8 thickness and its extra thickness can also improve its soundproofing characteristics. To receive the "Type X" designation under ASTM C 36, a gypsum board product must be shown to achieve not less than a one-hour fire resistance rating for 5/8" board or a 3/4-hour fire resistance rating for 1/2" board applied in a single layer, nailed on each face of load-bearing wood framing members.

7. Sound Proof Drywall

Sound proof drywall is composed of laminated drywall made with a mix of wood fibers, gypsum and polymers increasing the STC (sound transmission class). This drywall is denser that regular drywall so it might be a little harder to cut than other types of drywall.
