Can you expand on this? I am drywalling a 24'x24' cathedral cieling (trusses, not rafters), they are 24" on center and I am using 5/8" drywall, 12 foot long peices.24" O.C.? I's say to add strapping at 16" OC. Then install 5/8" GWB. Glue and screw.
If it's a large ceiling, and your trusses are moving, that is a whole different installation.
hmmm- maybe I can leverage that point - to feel a bit better about being a slow poke and taking forever on my project - the framing's been up for about a year and a half now - does that mean it's seasoned and possibly fewer pops when the drywall goes up?New lumber dries out and shrinks to some extent. This can cause fasteners to "protrude" back out of the stud slightly as they don't move with the lumber. Thus you get a nail/screw "pop". A common occurrence. You may not get any going into seasoned lumber
