When installing a ceiling, the sturdiness and thickness of the drywall you use is critical, and that might leave you wondering, can you use 1/2 drywall for ceilings? It is critical to get this right because ceilings are going to be above your head at all times – so you don’t want any risk of them falling in!
You can use ½ drywall for ceilings if the building code does not dictate otherwise, but you should be aware that in certain situations, it is a legal requirement that you use 5/8 drywall. Check local codes and stipulations, but this is often the case if the span is more than 16 inches on the center.
Understanding how to install ceilings is critical, so in this article, we’re going to explore when you can use ½ drywall for ceilings and when you need thicker drywall. This should help you install ceilings correctly or check that your contractors are doing so!
Can You Use ½ Drywall For Ceilings?
½ drywall is one of the most commonly used sizes for ceilings, and a lot of installers use this. It is particularly common in the DIY trade for a few different reasons, including:
- It minimizes the amount of sagging between the joists because the product is relatively lightweight
- It is fairly easy for the homeowner to install, even without assistance
- It is strong enough to support its own weight
- It is reasonably easy to hang and attach to the existing roof structure
- It is light enough to carry, weighing around 57 pounds, and measuring approximately 4 feet by 8 feet
All of these things make it popular with DIY enthusiasts and even some contractors, because it does the job and it is reasonably easy to handle. Thicker drywall pieces will almost invariably require 2 people for the installation because of the additional weight. They are much more cumbersome and challenging to hang, and even lifting them into place can be difficult.
If you are fitting your own ceilings, therefore, ½ drywall is probably the best option, and it is the standard for most ceilings, as well as many interior walls. However, you do need to check whether it is acceptable in your situation, because sometimes the building codes will require thicker drywall be used – in which case, you need to comply.
When Do You Need Thicker Drywall?
You will need to check your local building regulations and codes to make sure you are adhering to their rules, but many homes have rafter spaces or trusses with 24 inches on center, and these require you to use 5/8 drywall because it reduces sagging, increases structural integrity, and can also slow down any fire spread.
Some people do not bother to comply with the local building codes and simply use ½ drywall wherever they want to when building ceilings. This can work out fine, but you should be aware that these ceilings will not pass inspections and could result in the property being deemed “unlivable” as a result.
It is crucial to check building codes in advance, therefore. Before you buy your materials, find out what space you are going to be installing the boards over, and what the local stipulations are. Meeting the building codes will ensure that your home is safer and that it can pass inspections.
You may never run into any problems if you install ½ drywall where you should install 5/8 drywall, but it is still not a good idea to do this. Even if the drywall doesn’t sag, it won’t be up to the building standards and it may cause other problems. Make sure you are complying with the law so that your building is legal and safe for all occupants.
How Heavy Is 5/8 Drywall?
A 5/8 sheet of drywall will usually weigh just over 70 pounds, making it significantly more difficult to lift and maneuver than ½ drywall. Some contractors are capable of lifting and installing the heavier boards, but it is important to be aware of how much heavier this drywall is. It may look thin and lightweight, but it is not.
If you are going to be installing 5/8 drywall, it is highly recommended that you have a minimum of two people who are capable of lifting the boards, because there is a high risk of damage or injury if only one person is installing it – especially if they have limited experience.
Ideally, you should be using a drywall jack or lift when you are installing it, rather than trying to lift it yourself. This is especially true when you are building ceilings, since you will be working above head height, and the risk of accidents will be greatly increased.
FAQs
Q: What is the thinnest drywall for ceilings?
A: The thinnest type of drywall used on ceilings is the ¼ drywall, but you should be aware that this is usually only used as a skimming material. It is a great way to hide blemishes on the existing wall and create a fresh new look, but it should not be used structurally, as it is not strong enough on its own.
Q: Is drywall too heavy for ceilings?
A: No, ½ drywall is frequently used for ceilings, as is 5/8 drywall. You should also be aware that you can buy special lightweight ½ drywall, and these boards only weigh around 54 lb. They are much easier to install, especially if you are working alone, but make sure they meet the regulations for your area. Bear in mind too that they are likely to be more expensive.
Q: Is 5/8 drywall more rigid?
A: Yes, it is more rigid, and it is also better at blocking fires and drowning out noise.
Conclusion
Many people use ½ drywall for ceilings and it should work well, but you must be aware that it is not legal in certain spaces. Always check your local building codes before you start purchasing and installing drywall, or you are at risk of failing inspections down the road.
