Questions at the end mostly related to how to mount sheet rock to channel.
After an extended hiatus I'm finally making some progress on the basement build (http://www.avsforum.com/forum/15-ge...97-netracer-s-general-ht-game-room-build.html)
Some background
I have resilmount a96r clips fastened to joists holding 2 11/16" 25guage metal furring channel mounted perpendicular to the joists. I also installed custom made backer boxes for the light cans fastened to joists using 2 RISC clips. Roxul insulation will be installed in the ceiling
I'm installing 2 layers of 4'x10'x5/8" sheet rock (assuming 10' makes it down the stairs) with green glue in between
I plan on using 1 1/4" fine drywall screws for 1st layer and 1 3/4" for 2nd layer.
QUESTIONS
Q. When mounting the furring channel, the 1st channel parallel to a neighboring wall is recommended to be 6" away from the wall; what about distance of the first clip and start of track from the perpendicular wall? All the drawings I've seen seem to indicate very close to the edge. Could it also be up to 6" like the other wall? The joists aren't exactly lining up so this might make more work for me depending on the answer.
Q. Do the layers of sheet rock need to be perpendicular to each other or just offset so there are no seams between the top and bottom lining up allowing a sound pathway? I'm hoping for figure A below.
Q. Acoustic caulk in joints on the first layer or is that a waste of time?
Q. Do the seams for either layer of rock need to line up with the furring channel? If yes, which layer?
Q. If layers of rock need to be perpendicular to each other, which layer of sheet rock should be perpendicular to the furring channels?
