Selecting the correct size of the drywall is the first step to take when purchasing your drywall.
Thinner drywall panels like the 3/8 and 1/4 inch thick drywall are more flexible and tend to break easily.
On the other hand, 1/2 and 5/8 inch thick drywalls are more sturdy though heavy.
However, you need to consult your local building codes to verify that you are using the right size of drywall.
The thickness of the drywall you require essentially depends on the purpose you intend to apply it. For example, if you are working on your home project, using 1/2-inch thick drywall is a better choice because it has more thickness and different varieties. However, if you need to repair old drywall, using 3/8-inch drywall is appropriate.
3/8 Or 1/2 Drywall For Walls
1/2 inch thick drywall is the best for your drywall interior walls. The size is a better option because it is more sturdy and has different types, unlike the alternative.
The 3/8-inch drywall is uncommon and has only one standard variety. It is also less sturdy and has little resistance to water.
Using the 3/8 inch thinner drywall panels for your walls can cost you a lot of repairs in the future, as it is prone to damage over time.
Not only is the 1/2-inch drywall sturdy and durable, but it also has a fire-resistant drywall variety.
If the weight of the 1/2-inch thick drywall is a problem, you can opt for the lightweight type.
However, if you must use the 3/8 inch drywall, you can double the thinner drywall panels during the application, though it might cost more.
It is advisable to install the standard 1/2-inch drywall with an assistant because of its heavy weight.
3/8 or 1/2 Drywall for Ceiling
For your ceiling drywall installation, thicker drywall is a better choice, which means 1/2-inch thick drywall is optimal.
However, you should consult your local building codes before choosing.
If there is no specific size for ceiling drywall in your local building codes, the 1/2-inch moisture-resistant drywall is your best option.
The 1/2-inch drywall is more common and durable than the 3/8-inch thinner drywall panels.
You can use the latter option if the frames supporting the 3/8 inch drywall are 16 inches apart. Also, avoid using water-based texture as it is not a moisture-resistant wall.
Finally, you may be unable to use insulators, install lights, or other ceiling fixtures if you use 3/8-inch drywall.
If you want to use more robust drywall than the 1/2-inch drywall, opt for the 5/8-inch drywall for your ceiling.
The 5/8 inch drywall also has a fire-resistant variety. Though you can use any drywall size, purchasing thicker drywall panels for your ceiling is more cost-effective.
If you use the 3/8-inch panel, it might sag between the ceiling beams over time. If you use lighter 3/8 inch drywall panels, ensure to fasten the drywall panels to the ceiling beams every 12 inches.
Though you can hang a 3/8 inch drywall on your ceiling, it is more helpful in repairing holes in your drywall ceiling.
If you cannot lift the 1/2-inch thick drywall, you can purchase a drywall lift to assist you in hanging the drywall on the ceiling.
Also, if you are doing this yourself, try to work with a partner to avoid any health risks.
