Title: Options for resilient channel
Post by: llvora on October 08, 2010, 09:38:23 PM
I'm trying to sell some unused Auralex resilient channel on craigslist,
Somebody emailed me and said they could get "something very similar" for only $3 per 12' length.  It's about 1/3 the price of the Auralex channel.  This is in New York state. 
Are the much cheaper kinds of resilient channel also good for soundproofing, or not?

RC 8 is basic resilient channel with one leg (screw down location), They all deliver similar results.  Usually drywall contractors can pick this up pretty cheap...

How does Auralex stay in business, selling it for 3 times the price that other people do, if it's the same thing? 
If something is 1/3 the price, I tend to think there must be some difference in quality?

The only differences would be the gauge 20,22, or 25 gauge.

otherwise I have yet to see any other differences...they all screw directly to the stud or joist.
does it have an additional padding tape applied to it like our pre dampened version?

So is the cheaper resilient channel maybe made of thinner steel? 
If it is, it wouldn't hold 2 sheets of drywall, which the Auralex channel does?
That would be significant.  When I was doing my soundproofed wall, I glued mass-loaded vinyl onto a sheet of drywall, and it ended up heavy.

yes, you have a heavier gauge of channel...cheaper RC-1 is designed for single layer drywall.
