Should ceiling drywall run across ceiling joists or parallel? Should ceiling drywall run across ceiling joists or parallel?
When drywall ceiling panels are installed, it is best to install them perpendicular to the ceiling joists, instead of parallel to the ceiling joists. Also, make sure that the butt joints are staggered, so that continuous seams are avoided. A good way to do this is to layout the panels in a subway tile pattern. This will help to make concealing the seams easier to do, and it will also help to prevent the mud from cracking. Finally, make sure your layout allows the edges of your drywall panels to end on a joist, for secure attachments of the panels.
