The Thickness of Sheetrock for a Ceiling
Residential. Unless local building codes specify a thickness for ceiling drywall, using panels that are one-half inch thick on ceilings with 16-inch joist spacing is standard. Soundproofing, fire retardant, or wider joist spacing are a couple extra things to pay attention too.
Run a utility knife along your square to cut the paper and some of the drywall core. Take the knife out and place it at the bottom of the drywall to make the rest of your cut in an upward direction. If you are not tall enough to reach the top of the drywall sheet, you can lay it down on the floor to make your cuts instead. Use a new, sharp blade since a dull blade could tear the paper on your drywall.

While researching we ran into the inquiry “How much does it cost to install drywall ceiling?”.
Installing a drywall ceiling costs $300 to $400 for a 150-square-foot room. Expect to pay $2 to $3 per square foot for labor and materials. Standard, smooth drywall ceilings are the easiest and cheapest to install. They look great in any room, especially when painted the same color as the walls.
What is the deflection limit for drywall?
For drywall assemblies it is desirable to limit deflection to L/240 (L =. length of the span) and to never exceed L/120 (L/180 in some codes). The preferred limit for veneer assemblies is L/360 and should not., and exceed l/240.
A common question we ran across in our research was “How far can drywall span unsupported?”.
The general rule of thumb is that drywall can span up to 24 inches horizontally without support. This allows you to make a small soffit up to that wide without any framing. How do you layout a wall 24 on the center? What is the distance between 24 on center studs?
When installing drywall, ceiling or walls first?
Yes, you should install drywall on the ceiling before the walls for multiple reasons: Hanging the drywall on the ceiling first is not only simpler but will lead to longer-lasting results that require fewer future repairs. Installing the materials properly the first time around will make your life easier in the long run.
Is it better to lay drywall on studs or walls?
However, the pattern in which sheets of drywall are laid-out on the studs is very important for at least the following two reasons. First, properly laid-out drywall is easier to tape and finish and second, it is stronger and better at resisting cracking at the seams.
Should drywall be staggered?
Generally, yes, sheetrock should be staggered. Most drywall contractors recommend staggering sheetrock boards so that the joints in one row do not match up with the joints in the next row, which adds strength to the wall or ceiling and helps minimize cracks.

Does staggering drywall seams make a difference?
Drywall seams should be staggered to make walls stronger and seams less visible since they are often difficult to finish and can be noticeable in the end result.
Another frequently asked query is “Should drywall butt joints be staggered?”.
This makes it easier for taping and finishing and increases the overall strength of the entire wall.

The wood species, grade, and spacing between joists determine the distance a joist can span. A #2 Southern pine 2×6 expected to support 10psf DL and 40psf LL can span 9’-11” at 12” O. C, and 7’-7” at 24” O.
The maximum distance a 2×6 can span, according to the 2018 IRC, for a floor joist, is 12’-6”, ceiling joist 20’-8”, rafter 18’-0”, deck board 24”, deck joist 9’-11”, deck beam 8’-3”, and 6’-1” as for header. Always check the codes for determining factors or consult a Structural Engineer.
