RC-8 Resiliant Channel's effectiveness has been well documented for years. The problem is, RC-8 isn't available in many locales or is available only to licensed contractors. This led to numerous customers calling Auralex saying they couldn't obtain RC-8. Not to worry ... Auralex has you covered.
RC-8 should be installed horizontally at the bottom and top of your wall, then every 2' or less in between. Up to two layers of 5/8" drywall may be hung on RC-8. It comes in a handy 8' length that's UPS shippable.
