Auralex RC8-RES-CHANNEL Pack of 24 Resilient Channels, 2.5" x 8'

Auralex's RC8 Resilient Channel is a specially-formed, sturdy metal device that, when used to hang drywall (instead of just attaching the drywall to the studs or joists), GREATLY improves the sound transmission characteristics of the wall or ceiling system.

RC8 should be installed horizontally at the bottom and top of your wall, then every 2' or less in between. Up to (2) layers of 5/8" drywall and a layer of SheetBlok may be hung on RC8, even on a ceiling.
