Lunatic - I think you have it reversed. The channel is most effective when placed on both sides of the wall. It's been said that it has little effect when placed only on one side but I still used it on all my exterior walls too. Anything to reduce physical contact with the studs and allow the sheetrock to "flex" will certainly have a positive effect.

au contraire... adding RC to the two sides of a wall separated will HARM your acoustic wall. forgot what the theory behind it is, but I *think* your coincidence freq goes up, which is no good, you want that as low as possible...

***URGENT***

ok were going to hang drywall tomorrow. were wanting to hang from the ceiling 2 sheets of drywall from Zchannel. will the z channel support it? also any suggestions on doors? glass, hollow, solid?
 
In reality you need to check with your local building department.

However, on the ceiling I think that having your steel channel at 16" on center should hold two layers of drywall. If in doubt, do 12" on center.
 
16" centers should hold two 5/8" layers of drywall no problem, 12" centers would hold 3 layers.

On walls, RC on both sides would let both sides move in tandem, lessening the isolation. Plus, it's a waste of time and money.

IF you check the SAE site

Click on STC charts, and you'll find that RC in a simple, single-layer both sides 2x4 WOOD stud wall, increases STC by 5 dB. The figure for that wall is the same as a METAL stud wall with NO rc (again, waste of time and money)

The metal studs are so flimsy that they act the same as RC, allowing the two sides of the wall to be more independent which cuts down on transmission, due to decreased coupling (compared to wood studs)

When putting multi-layers on RC, be sure to make marks or masking tape indicators on the two adjacent surfaces where the studs are, so you won't put a screw thru the RC into the stud and short out the channel.

From Lunatic - "Another thing... what Elevate was referring to in an earlier post is known as a drywall lift. You should be able to rent them at your local rental place.

I highly recommend you use one. We used one in finishing the basement in our last house and it was a life saver! Especially when your trying to hang 5/8" drywall on the ceiling."

Couldn't agree more. Rent them, no matter what they cost. Years ago when I was actually YOUNGER than dirt, I helped drywall a huge upstairs in an old commercial building - we used 5/8" sheet rock in 4 x 12 sheets - thought I was gonna DIE (wide sawhorses, holding sheets with our HEADS and using NAILS, with those funny waffle-head drywall hammers) - not sure which part of me hurt worse, my head/neck or my wrist (you have to pound the nails by ROTATING your wrist because of the close quarters) ugggghh...

Another good thing about steel studs for interior walls - you don't have to miss the knots, throw away the twisted ones, or mess with RC... Steve
 
I would like to second the motion for steel framing. It's very easy to work with and less expensive (if I remember correctly) than wood. You'd be surprised how quickly your walls go up.

We used them in the same basement I reference in regards to the drywall lift. I'll also be using them in my new studio.

Ok we are using 16 on center and 5/8 drywall so it seem very solid (pictures coming soon). We’ve hung about 70% on the ceiling and the rest tomorrow (late start) Now all I have to is worry about doors. I still have no clue.
 
we'll here are some new pics of the constuction we did the past week.

new pics

and here is the glass door I plan to use for the interior the exterior I'm just going to use a solid core wood door
