What thickness drywall do I need for 24" OC wall studs in a …
I am currently finishing an older 3-car detached garage. Both the wall studs and the ceiling trusses have 24" OC spacing.

drywall - How to prevent sagging ceilings when joists are spaced …
2020年10月16日 · The simplest thing to do is install strapping - 1" x 3" furring strips that run perpendicular to the joists.

Strapping is used a lot in some areas of the US and seldom seen in others.

Hanging ceiling drywall, rafters not all 24” center?
2020年4月3日 · Add a comment. Best way - 1x3 strapping at 90 degrees to the vaguely located rafters (bottom chords), precisely located. Note that you can center the strapping at 24, 19.2, 16 or 12 inches, as desired, and that at any spacing it gives you 2.5" ("dressed" or planed 3") of target surface, not 1.5" as your dressed/planed 2" bottom chords do.
Ceiling Drywall Screw Spacing - GreenBuildingAdvisor
2016年12月11日 · Hi all, Currently have 1/2" drywall secured to the ceiling with nails every 12".

How do I consistently drive drywall screws to the correct depth?
The biggest mistake you can make when screwing in drywall is to drive the screw too deeply, tearing the paper outer layer. The paper is what's holding the plaster inside together enough to be screwed down in the first place, so keeping it intact is the key to a secure connection.
How much seam allowance should I have for drywall joints?
2013年7月1日 · My recommendation is to have no gaps larger than about 1/4 inch (5mm). An exception can be made for certain types of joints that are to be trimmed over with edging. For example on an outside corner or in a banded door opening it can actually be an advantage to hold one corner of the drywall from the overlapping side as shown below.
What is the usual maximum load for drywall? [duplicate]
It also depends on stud spacing: with 24" spacing, the drywall won't be able to support the same load as 16" spacing. To an extent, how it's joined could play a factor. For example, if it was put up using only nails, it's going to tear off the wall at much less load than if done using screws every 12". – gregmac.
