Resilient Channel Wall Assembly:

We do not suggest installing Resilient Channel walls. They test well in the lab but when installed in the field they are seriously prone to malfunction. Our purpose for posting this data is so you have a point of reference. Resilient Channel was the standard in soundproofing in the past, but has become obsolete. If you are a contractor do not attempt to use this product with any guaranteed sound performance.
