For Wall & Floor Ceiling Assemblies

RSIC-1 Resilient Sound Isolation Clips provide 2 unique approaches to sound privacy that will prevent sound from noisy neighbors transmitting through your walls or floor/ceiling assemblies.


Experience with the RSIC-1 resilient channel sound isolation clips has recorded remarkable improvements of up to an additional 20 STC points on walls.


The RSIC-1-R resilient channel sound isolation clip is designed to retrofit and improve existing walls and ceilings has shown to improve existing walls by as much as 8-10 dB by actual field tests.

Walls – One and Two layers of 5/8″ Gypsum Board

  1. Resilient Sound Isolation Clip (RSIC-1) shall be 48 inches maximum on center (horizontal)
  2. Fasten the Resilient Sound Isolation Clip (RSIC-1) to the substrate with a fastener approved for a minimum pull-out and sheer of 120 lbs
  3. Ensure the ceiling sound isolation clip’s internal metal ferrell is tight to the substrate
  4. Locate the first row of RSIC-1 resilient channel sound isolation clips within 3 inches from the floor and within 6 inches from the ceiling
  5. Snap in the drywall furring channel (hat track) into the RSIC-1 resilient channel sound isolation clips (horizontal for walls)
  6. Place 1/4″ (minimum) shim on floor to fully support the gypsum board
  7. Install the gypsum board from the bottom up leaving a 1/4″ min. gap around perimeter.
  8. ONLY remove the shims after ALL the gypsum board is completely screwed to ALL the drywall furring channels. Make sure every screw (floor to ceiling and wall to wall) is installed as required by the resilient channel clip’s design, in every layer of gypsum board before removing the shims at the floor. The shims are critical to ensure best results with sound isolation clips
  9. Caulk around the entire perimeter of the gypsum board. Use fire and smoke rated acoustical sealant where required
