sound board then drywall?
« on: December 15, 2000, 05:00:03 PM »
Ive spent the last few days reading everything on this web page. I am in the process of sound proffing a room for my band to practice in. It is an existing room that was part of the garage. So far I have covered the existing walls with sound board and caulked all the cracks and spaces, even all the corners. And I have just finished putting up the resilient channel. I was thinking to put more sound board over the rc channel, but then i read that it would be good to use 5/8 inch drywall over that to kill bass frequencies.
Now, I know when I put the dry wall onto to sound board the screws holding the drywall are not suposed to touch the rc channel. Here's the problem, 5/8 dry wall is really heavy- and screws dont really hold in sound board because it is so soft.
Is there a better way to fasten dry wall to sound board, without hitting the rc channel- keep in mind this is on the ceiling too.
Or, would it be better to put up the dry wall first then sound board over that?

Use vibration pads to set the drywall/soundboard combo on, then the screws just balance the wall assembly.  On the ceiling, place your RC-1 channel on 12" centers, use some screws thru the channel and use construction adhesive as well between the drywall and soundboard.  Drywall is always out.
