I am about to start a ceiling in the basement with drywall. Is there
an advantage in using 5/8 in rather than 1/2 in drywall ??
Thanks.

typically, 5/8" is used on ceilings because it is stiffer and will be
flatter. however, i have seen 1/2" used on ceilings successfully if the
joists are 16" on center or lesser.

Increased fire blocking. less sagging and heavier trying to put up.

Thanks. My Joists are spaced 16 in OC and I am planning on applying
the wallboard directly on the joists. From what i've seen in the rest
of the house , the Joists may not be level. If the 5/8 will help to
correct some of the problem, I'll go for it then. Is there any
advantage in stargering the joints? or just apply parpendicular to the
joists symmetrically ?

Thanks.

Most building codes require 5/8" for flame resistance.

There are 1/2" boards specifically made for ceilings, such as
SHEETROCK® Brand 1/2" Interior Gypsum Ceiling Panels

Lighter weight so it's easier to install and it's stiffer than regular
1/2" rock. Good way to go.

I would suggest that if you really have joist that are not level, 5/8
will not fix that, you need to shim the joist to get it properly flat.

Do you mean to install shims between the joist and drywall as needed ?

Sort of.

I had can lights put in my kitchen this week (late '50's split level). The
ceiling was plaster OVER drywall. It was 7/8" thick. They also used
chicken wire in the corners. Just thought I'd share...

You can also use 1/2" high density board. Hand trowling will help hide
any defects as well and looks more professional in my opinion.
