RSIC 1.5" Cold Rolled Channel Clips for Drop Ceiling

The RSIC-1.5” CRC® Clip is designed for use with any joist or concrete application where a dropped drywall ceiling is required. This assembly combines a 1.5” CRC Clip with a Hat Channel System to decouple the Gypsum Board from the floor structure above, giving the assembly enhanced acoustical performance, while allowing for a chase to hide mechanical ducting and plumbing lines.

  • Drop ceiling creates a chase to hide mechanical ducting and plumbing lines
  • Compatible with 1.5" Cold Rolled Channel

RSIC 1.5" CRC Specifications:

  • Acoustical Design Load: 36 Lbs.
  • Cavity Minimum: 3.5"
  • Cavity Maximum: No Limit
  • Adjustment Limit: Length of Wire
  • Use on Ceilings: Yes
  • See Product Data Sheet for more information.

How Many Do I Need?

  • For a tight estimate, when spaced at 48" x 24": Take the square footage of the area to be treated and divide by 5.
  • However, to compensate for being within 6" to the walls / ceilings, we have found that calculating 23% of your total square footage will give you a more accurate estimate.

Product Data

How it Works:

RSIC Clips and Hat Channel Systems are used in the process of decoupling walls and/or ceilings from the joists, creating what is called a floating wall or ceiling. Decoupling the wall or ceiling helps create a soundproof environment in two ways, by breaking the path and creating resiliency.

The Clips are generally spaced every 48” OC, making the contact between the studs and boards minimal. This break in the path greatly reduces the amount of noise that travels from one side to the other in two ways. Firstly, there is no direct connection for sound to travel via the joists as the wall/ceiling is disconnected. Secondly, the wall and ceiling are given resiliency (flexibility), thus greatly reducing vibration (similar to shock springs on a car).
