Hi. I'm replacing canec in a 1950s house with light weight drywall. According to the irc, the thickness is fine so long as the drywall is placed perpendicular to the ceiling joists. My ceiling joists have 1x2 old growth redwood lathing running perpendicular to the ceiling joists, to which the original canec was attached. Should I run the new drywall perpendicular to the ceiling joists and parallel to the latheing strips, or perpendicular to the latheing strips and parallel to the ceiling joists?
Thanks.
Thanks.
