If You Live In A One-Storied Building

A thick, rigid, and fireproof drywall is needed for houses with multiple floors. These types of houses or buildings need a lot of support in their ceilings as they need to carry the weight of the upper floor. 

On the other hand, if you happen to live in a one-story house then you don’t need all of that rigidity or stiffness. 

Your one-story home doesn’t need to support the weight of multiple floors on top. As a result, you don’t have to get thick and strong drywall for your ceilings. 

If You Don’t Need Soundproofing 

If making your rooms soundproof is not a concern for you then you don’t need a ⅝ drywall. Due to its thick nature, the 5/8 drywall soundproofs your room effectively. 

You can easily get away with using thin drywall compared to the ⅝ inch drywall in case you don’t need a soundproof ceiling. So look for other drywall options on the market.

If You Don’t Need Fireproofing 

The other name of the ⅝ drywall is the firewall. Due to its thick proportion, it easily acts as a firewall. 

If you live in a home with no floors on top then fireproofing your ceilings is not necessarily needed. There is a very slim chance of fire spreading in a one-story house. 

So, paying a premium for the fireproof drywall when you don’t need one is a waste of money. 

If You’re Looking For A Lightweight Drywall

The ⅝ inch drywall is thick, sturdy, and extremely heavyweight. This is essentially used in homes that need a supportive ceiling. 

As it’s heavyweight drywall it may not be suitable for your home. In this case, you need to opt for lightweight drywall that won’t bring down your ceilings. 

That’s all you need to know regarding whether you put ⅝ drywall on your ceilings or not.
