I am working on an older home where the white and brown coat of
plaster are very bouncy. I am overlaying the walls with 1/4 drywall
(screwed and glued), my question is will 1/4 drywall be strong enough
for the ceiling or will I want the additional screwing depth that 1/2
will provide.

Thanks for any thoughts

I've used 1/4" for the same purpose but I've also used 3/8" and prefer it.
