How is a ceiling framed?
Conventional room frames are built with beams and timber joists that run down the lengths and widths of ceilings, plus concrete and metal materials.

How far apart should ceiling joists be for drywall?
Regular 1/2-inch drywall ceilings can be hung perpendicular if joists are spaced 24 inches or less apart (*always refer to local codes). If hung parallel, the maximum spacing is 16 inches on center.
Do you have to strap a ceiling before drywall?

Walls that run perpendicular (at a 90 degree angle) to the ceiling joists are load-bearing. Walls that run parallel (in the same direction) as the ceiling joints are non load-bearing. Ceiling joists are spliced over the wall.
Should I nail or screw furring strips?
For furring strip installation, affix the strips across the joists every 24” on center with screws or nails at least 1” long so that they will go into the joist with a minimum depth of 1/4″. Use shims, if necessary, to achieve a uniform flat and level ceiling or wall.
