I'll be hanging blueboard which will be finished later by a professional plasterer. Haven't found one yet who has time to give me a bid.
I'll be going over new wood framing. I've got four questions somebody might be able to help with:
Can I use 1/2" for both walls and ceiling, or should I use 5/8" on the walls?
How close together to I need to put fasteners in the field?
Should I install a plastic vapor barrier on the bottom chords of my trusses before I hang the ceiling?
Since this is an addition over my garage, when I re-rock the garage ceiling, does it need to be fire-rated board?
Thanks for any help you can give.
