White board, Standard or Regular:
It is usually white on one side and brown on the other. The most pocket friendly drywall type as well as the most common drywall used. it is also known as Standard drywall and doesn't have any special features added to the design. Comes in different sizes ranging in thickness from 3/8 inches to one inch. It is popular inside residential construction. Suitable for walls and ceilings. Suitable for finishing basements.
It is the most commonly used backer board for all manner of ceramic and porcelain tiles. Made of cement and reinforced on the top and bottom with fiberglass, this waterproof backer board is generally used for tiled shower surrounds and floors in wet areas. As a tile backing board, cement board has better long-term performance than paper-faced gypsum core products because it will not mildew or physically break down in the continued presence of moisture or leaks..
Also commonly referred to as the moisture resistant drywall. This drywall features a special paperless backing and an additional coating to prevent mold and moisture. You can use it as a tile backer in areas with minimal wetness e.g. basement areas, kitchens, laundry and utility rooms. Note that it is not waterproof, so ensure that it is not set up in a place where it is going to be near water.
Also referred to as the plaster baseboard, this type of drywall is convenient for veneer plastering as the surface paper has unique retention qualities. Unlike the green board drywall, blue board works great in bathroom areas or places that get in contact with water. It has great mold and water resistance qualities. Helps extend the appearance of interior surfaces in wet or humid areas.
It has a covering of fiberglass rather than paper. It grants greater resistance to mildew and mold, plus it shields the gypsum board from blight. It has some slight textures that will require applying joint compound to achieve a smooth clean finish drywall level, but nothing out of the ordinary.
Mold-resistant drywall aka purple drywall can be set up on all ceiling and wall applications as well as in areas with high levels of moisture. Due to its improved moisture resistance, this drywall becomes favorable in areas prone to mold and moisture.
Fire-resistant drywall, constitutes unique non-combustible fibers. It is usually used in apartment buildings, rooms and garages because it’s a requirement in numerous building codes. It comes in 5/8” thickness and this extra thickness enhances its noise-proofing characteristics. It is used where fire rating is more than 20 minutes.
Fire-resistant drywall is the improved version of the X type. This fire-rated drywall type is available in 1/2” and 5/8” thicknesses and its gypsum core still consist of glass fibers. It contains more glass fibers than its x type counterpart and also additional vermiculite components. It is even more resistant to fire since it will slow its spread by 2-4 hours.
Sound proof drywall:
It is normally used in places where noise is an issue. It’s consisting of a laminated drywall built with a blend of gypsum, wood fibers, and polymers boosting the sound transmission class. May be a little bit difficult to cut as it is denser than the regular wall.

Finishing Drywall Systems
Level 0: Used in temporary construction or wherever the final decoration has not been determined. Unfinished. No taping, finishing or corner beads are required. Drywall is affixed to the walls and ceilings. All seams and drywall screws remain exposed.
Level 1: Drywall is affixed and least amount of finishing touches are applied. Only the drywall seams are taped and covered. Frequently used in plenum areas above ceilings, in attics, in areas where the assembly would generally be concealed or in building service corridors and other areas not normally open to public view. Some degree of sound and smoke control is provided; in some geographic areas, this level is referred to as “fire-taping,” although this level of finish does not typically meet fire-resistant assembly requirements.
Level 2: Drywall is affixed, seams are taped and covered and joint compound is applied to all joints, screws, and interior angles. Surface shall be free of excess joint compound. Tool marks and ridges are acceptable. This finish is common where surface appearance is of no concern, such as a storage or a garage.
Level 3: Drywall is affixed and finished with taping and covering of the seams. Also, joints, interior angles, and screws are taped and covered with joint compound. This finish is appropriate for areas that will receive sprayed textures, or medium to heavy paint texture.
Level 4: Drywall is affixed and finished with seams taped and covered and joint compound applied to all joints, screws, and interior angles. Two additional coats of joint compound are applied over the tape. Fastener heads and accessories are covered additional layers of joint compound. All coats will be sanded smooth. suitable for flat paint, light texture, or light wall covering.
Level 5: All the steps that were mentioned before are taken and final product is primed and is paint ready. The highest quality of drywall work, providing a smooth and uniform surface. It involves full coverage of the drywall with compound and primer, with no ridges or tool marks.
