As we have already provided a short comparison, now let’s get into the details. This will give you much more clarity on the differences,
Before you decide the thickness of your wall, definitely check your area guidelines. Every area has a standard guideline for every sort of wall. Look through them to see what thickness is applicable in your area.
Usually, multiple area building codes instruct you to install drywall on the garage door. This is due to the safety purpose against fire hazards.
There are plenty of other reasons behind choosing drywall. They involve aesthetics, insulation, and other multiple reasons.
Drywalls work as a great sound barrier between the garage and the house. Therefore, you can work in your garage without disturbing people inside the house.
Also, since drywalls are great insulators, it won’t retract heat from the entire house in the winter. If you look at the options, drywall is a great option to install in your house. Especially, standard or type X drywalls are highly recommended for your garage.
Attached Vs Detached Garages
If your garage is detached from your home, then definitely use ½ inch thick drywall. In terms of distance, detached garages are far away from your actual home. Therefore, you will be able to drywall all the walls.
Good thing that comes with it is, it will be cheaper for you. Using all ½ inches throughout is less expensive.
Even if you can get away installing ½ inches in walls, ⅝ is essential for the ceiling. Otherwise, the ceiling will bow against the trusses.
Since the majority of detached garages are square footed, they don’t need soundproofing. Also, most likely they are situated relatively far from home. So, using ½ inches wall in detached garages is the best choice for you. Also, it saves you money and time.
Are you thinking about buying ½ or ⅝ inch drywall sheets for your house? If so, You can give the given below drywall sheets a try. They are really good at their job.

Workshops
Sometimes, people use their garages as part-time or exclusively as their workshop. In that case, you need something else for a multi-purpose garage.
You are likely to have a lot more noise coming from your garages. Also, they will carry heavy equipment such as power tools, or even loud music. In such cases, a sound barrier is essential to have.
Furthermore, if you’re living in a cold area then heated insulation is mandatory. You need drywall that retains heat for working year around.
So, in scenarios such as such, ⅝ inch drywall sheets perform the best. Although it is a bit more expensive than ½-inch drywalls but ⅝ would be highly preferable.
⅝ inch walls have more insulation and also will provide a good sound barrier. Since most of the workshops contain small areas, it will be cost-efficient. Additionally, it will provide better insulation too.
Fire Resistance
Fire-resistant drywalls are often referred to as fire-rated drywalls. And type X is the best among all the fire-rated drywall.
Let’s be honest here. We will not ensure that they will prevent you from any fire hazards. Or, they will magically stop the fire if there is any. But type X drywalls are made with special non-combustible fibers. They are best at slowing the fire down which will give you enough time to reach a safe distance.
Type X drywalls usually are 4-foot by 8-foot diameters. They are denser than ⅝ inch drywalls and are used in most homes. Their installation procedure is similar to the typical drywall sheets.
Now for the other type, the fire rating for the ½ inch drywall is 30 minutes. But the rating for ⅝ inch is around an hour. So undoubtedly the ⅝ inch drywalls are better.
Fire-resistant drywalls are more expensive than regular drywall sheets. You will see an approximately 20 percent increase in the price range. But they are stronger and soundproof your home better. Typically inserting a fastener every 6 inches provides more safety from fire.
So, there are drywalls that you should use according to your geological condition. Each drywall performs better under different circumstances. So, read your area’s building codes and understand the weather you are living in. This will give you a greater understanding on which drywall would provide you with the best utility.
