Resilient Sound Isolation Clip-1 (RSIC-1®)
The Sound of Silence!


The RSIC-1® is designed for use with various framing designs and applications. The RSIC-1® decouples the Gypsum Board from the framing in wall and floor ceiling assemblies. The RSIC-1 has been acoustically tested, and adds 15 to 20 STC an IIC pts to your existing assemblies. Reducing the noise transfer by 75 to 100%.

When designed correctly into the wall or ceiling, there can be a substantial cost savings for the project.

The RSIC-1 is designed for use with any wood framed, steel framed, CMU, or concrete wall and ceiling system where noise control is needed. The RSIC-1 assembly decouples and isolates the gypsum board or plywood from the structure increasing the acoustical performance of the system. With an Acoustical design load rating of 36 lbs per isolator, the RSIC-1 clip can support up to two layers of 5/8" gypsum board when spaced at 24" x 48" oc. For heavier systems increase the number of isolators to support the additional weight of the system. The RSIC-1 clip fastens directly to the framing or structure creating a 1-5/8" cavity between the face of the framing and the back of the gypsum board. The RSIC-1 stops the noise and vibrations that typically would be allowed to transfer throught the structure. The RSIC-1 systems have several UL fire resistive design assemblies from ranging one hour to four hours. The UL assemblies can be viewed on our site at, and on
