Drywall is a non-structural panel typically made with gypsum and is used for separation interior spaces. Drywall panels may be fiber-reinforced for their strength and durability. Paper sheets cover the front and rear sides of drywall to preserve its stability at the time of manufacture and construction.
Here are some other names of drywall:
- plasterboard
- wallboard
- sheet rock
- gypsum board
- buster board
- custard board
- gypsum panel
How many types of drywall exists?
Drywalls can be used in rooms, kitchens, closets, basements, and even bathrooms. In humid areas, such as bathrooms or basements, mold and moisture resistant drywalls should be chosen. Mold and moisture resistant drywalls are typically green and have slightly a higher price.
To make a drywall panel lightweight, manufacturers add a foaming agent during the production. The foam contains air bubbles and reduces the density of the panel after curing. Nowadays, most of the drywalls purchased at stores are lightweight by default.
Which size of drywall is right for my project?
Drywall panels are in different widths, lengths, and thicknesses. The standard and commonly used width of drywall is 4 ft (48 in). But the length has more variation. Here are some available lengths at Home Depot or Lowes stores:
- 8 ft (96 in): easiest to carry and work with. It is the most commonly purchased by customers.
- 10 ft (120 in)
- 12 ft (144 in)
The thickness of drywall also can be varied depending on the application.
1/4-Inch Drywall: This drywall is good for installing on the existing walls. It can refresh the look, hide old blemishes, and cover a subtle curve.
3/8-Inch Drywall: This thickness is used mostly for repairing and patching after plumbings or electrical repairs.
1/2-Inch Drywall: This is the standard and most commonly used drywall for interiors.
5/8-Inch Drywall: The thickest drywall is often produced in fire-resistant and soundproofing categories. Another application is for ceiling when the thickness helps to prevent sagging and deflection over time.
