I submit for final review my ceiling plan.
I'm new to this so please let me know if I'm missing anything. The long wall on the top side of the sketch will have whisper clip + hat channel. All the other walls are decoupled using brackets, so I am putting drywall straight on the wall.
I plan on hanging:
1) First ceiling layer, acoustic caulk all perimeter 1/4" seams (to the wood top plate), leaving the seams between drywall sheets since they will be staggered & covered by 2nd layer
2) First wall layer 1/4" gap at ceiling, tight to floor, acoustic caulk ceiling & floor seams, leaving seams between drywall sheets
3) Second ceiling layer, acoustic caulk all perimeter 1/4" seams, leaving the seams between drywall sheets
4) Second wall layer, tight to ceiling and floor. Acoustic caulk ceiling & floor seams as seams between drywall sheets will be taped + mudded.
On the first ceiling layer I left 1/4" around the entire perimeter so it doesn't touch any vertical surfaces.
On the second ceiling layer, I accounted for the 5/8" drywall that will be installed on the walls at this point, and I left an additional 1/4" around it for acoustic caulk (is this necessary? Or should I install the 2nd ceiling layer tight to the 1st wall layer?). I also accounted for the whisper clip + hat channel on the long wall.
How's my plan sound? I am working on it tomorrow so hopefully if I mis-planned anything, someone can speak up. Thanks!
