Auralex RC8 Resilient Channel is a specially-formed, sturdy metal device that, when used to hang drywall (instead of just attaching the drywall directly to the studs or joists), GREATLY improves the sound transmission characteristics of the wall or ceiling system. Auralex RC8 Resilient Channel adds 1/2" of airspace between the studs and drywall and can provide as much as 10 dB of isolation if used properly.

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.

FEATURES:

  • RC-8 is made from 25 Gauge Steel
  • Greatly improves sound transmission characteristic of wall or ceiling system
  • Adds 1/2" of airspace between studs and drywall
  • Can provide as much as 10dB of isolation
  • Acoustically decouples drywall from supporting studs
  • Reduces structural vibrations
  • Wall & ceiling applications
  • Meets Class A Fire-rating per ASTM E-84*
  • Handy 8' lengths
  • Ground shippable

Installation Tips:

  • Position RC-8 Resilient Channel at right angles to steel studs, space 24" o.c. and attach to stud flanges with 3/8" Type S pan head screws driven through holes in channel mounting flange.
  • Use 1-¼" Type W screws to mount the RC-8 to wood studs/joists/framing.
  • Locate channels 2" from floor and within 6" of ceiling.
  • Install channels with mounting flange down (see picture below), except at floor to accommodate attachment.
  • Splice channel by nesting (not butting) directly over stud. Screw-attach through both flanges.
  • A 2-hr. floor/ceiling system with STC/MTC ratings as high as 60/54 is achievable with a ceiling of double-layer 5/8" gypsum board attached to RC-8 channels across joists with 3" Mineral Fiber Insulation in the joist cavities.
  • RC Comparison Table (PDF) contains a table of wall constructions with their 1/3 octave band Transmission Loss values, STCs and (when available) MTCs measured in accordance with ASTM E413. The table is intended for use in comparing wall systems before and after the addition of resilient channel. It is not intended to be a complete partition STC/MTC resource.

  • Auralex can provide fire test reports for many of their fire rated products performed by certified third-party testing facilities.
