Should I use RC-1 on my ceilings?

Posted: Tue Aug 19, 2008 9:01 am

I bought resilient channel (RC-1) to be installed on my ceiling but am now having second thoughts. I need help deciding if I should use it or just go without. The studio is in my house and I feel the ceilings are a weak point. The walls are double wall steel frame construction. The ceiling consists of a layer of plywood on the upstairs side which I have beefed up with a layer or drywall. There is an 18” cavity and I am using r-19 fluffy fiberglass insulation. The joists are 20” OC and I was planning on installing the RC-1 16” OC with layers of 5/8” and ½” drywall.

I have been reading that it’s nearly impossible to install without shorts and that even a single short will negate the benefit of using it. I’m also a bit worried about the RC-1 bearing the weight of 2 layers of drywall. I have already installed the RC-1 in my control room but I would be willing to remove it if people think the RC-1 is a bad idea. Would I be better off with just 2 layers of drywall and perhaps Green Glue?

If I do end up using it are there any tricks to installing it? I can’t seem to find installation instructions anywhere.

I found this pretty informative.

Also did a google search for "RC1 resilient channeling" and found some interesting threads from people with similar problems.

Just 'cause I like to be different...which is really difficult to do in a house full of people that just like to be different.
