Density + Disconnection

The RSIC-1 mechanical sound isolation clip system is designed to disconnect your framing by creating an air gap and minimizing contact points. The rubber feet help to further reduce sound transmission by dampening sound energy that has been converted to structure-borne vibrations.   

The traditional methods used to soundproof a room involve constructing walls with staggered studs or double studs to decouple the adjacent rooms. These methods are not only expensive due to the increased material required, but also take up a significant amount of space. Our recommended assembly method of dB-Bloc>RSIC-1 Clips>Hat Channel>5/8″ sheetrock is less expensive, provides more acoustical performance, and takes up less space.   

The art & science of disconnecting your common surface is addressed in both our Walls and Ceilings sections of this website.

Forcing Disconnection

For new construction or exposed frame treatments, the correct assembly order to follow is:

1. Anchor dB-Bloc directly to your studs – tape the seams (adds mass)
2. Add the RSIC-1 Clips (decouples the wall & creates air gap)
3. Hat channel snaps into the RSIC-1 clips
4. Finally, finish with a layer of 5/8″ drywall

For finished wall surfaces, do the same.   For concrete block surfaces, reverse the process.   Anchor the clips to your concrete surface first, then snap the hat channels into place, then your dB-Bloc and your finished layer of drywall.   This will help separate the density of dB-Bloc away from the concrete surface.    The resulting dead air gap between the two masses will then collect and dissipate the trapped sound waves!
