The why of ceiling strapping?
#1

I'm in the process of insulating and drywalling a detached garage. I've been advised to install strapping before installing the drywall on the ceiling.
The garage joists are 16" on center so I'm not sure why strapping makes sense - I'm under the impression that strapping is only suggested when the joists are over 16" on center - is there some good reason that I'm overlooking?
Many thanks,
Chris

Don't know the "book" answer, but I use 1x3 strapping:
- to make sure I'm 16" oc,
- to help with the rolled insulation,
- and most importantly, to provide a flat surface for attaching the drywall. It's not uncommon for ceiling joists to 'not' be perfectly in line and level with each other. Strapping and shimming ensures that you'll have a flat surface to hang your (fire retardant) drywall, which of course will provide you with a flat even ceiling.
