Does anyone have any insite in the installation of drywall with resilient channels? Is it much more difficult to install than the traditional way? Do you need special drywall screws to fasten the drywall to the channel?

Also, I am trying to find the best cost effective solution to sound control in my basement ceiling. Besides the channel and 5/8" drywall, does anyone have any suggestions. I have thought about stuffing compressed insulation between the joists. Any thoughts? Thanks

I struggled with all these questions and eventually got frustrated. In the end I did not go with the resilient channel as I couldn't get the answers. I have a teen-ager in my basement and sound proofing was my ultimate goal. I believe the resilient channel only attaches with one edge to each surface which supposedly cuts down on noise transferrance.

Here is what I did and it seems to be effective but not 100% as we still "feel" the thump thump thump of what she refers to as "music". Normal volume stuff (like the TV etc) is just about cut right off from our ears in the floor above. First I bought an insulative wrap for the heating ducts that passed through the roof of her room and feed the upstairs. Once this was installed I bought some R20 insualtion and placed it between floor joists above her room. I then purchased some simple metal channel at the Home Depot. This channel was cheap and had roughly the dimensions of a 2 by 3. Regular drywall screws worked great in combination with the 5/8 drywall that I put up. The most expensive part was the duct wrap but I am happy with the results and I don't think it cost more than $100 for all the insulation wrap and channel for a 16 by 14 room.

 

I attached drywall to resillient channels with self-taping 1" drywall screws. It went pretty well.

I went pretty well. I had to put a grid of chalklines on the drywall to indicate where the channel was and where the floor joists were. I used RED chalk to indicate where the joists were. You definitely don't want a screw on the RED line.

I had difficulty screwing into the channel when I got to the wall. There wasn't enough resistence for the screw to attach. I had to start as close to the joist as possible and start walking the screws down towards the wall.

Works wonderfully. Be sure to follow the installation instructions and don't short out the ceiling. You'll be glad that you used this product.

BTW, if you're looking at resiliant channel for sound control purposes in a home theater or music listening room, I suggest rethinking. RC tends to dampen too much - the room will sound dead. There are alternatives to RC that work well at both sound control and sound quality, but (of course) they're not as simple as RC.

In addition to the links that twelvepole provided, I highly recommend the Home Theater Construction forum over on www.avsforum.com . Lots of in-the-know people over there doing projects from big to small.
