Product Description
A Resilient Sound Isolation Clip (RSIC-1) creates a high STC (Sound Transmission Classification) rating for your wall or ceiling assembly and offers an economical method to “float” your walls or ceilings. These isolation clips are used for vibration control of structure-borne noise and help build assemblies that will more effectively block airborne noise transmission. For higher rated sound blocking applications with improved STC ratings, use isolation clips in combination with our AudioSeal® Sound Barrier or Green Glue Damping Compound.
Resilient Isolation Clips are made with a natural blend neoprene grommet pad and threaded shaft, which is attached to a center bushing made of electroplated zinc mild steel. The center bushing is approximately 20 mm long, with a 10 mm shaft section and a 21.5 mm end clip. The natural neoprene isolator is 1 1/2″ x 1/2″.
The RSIC-1 model is designed for use with any wood, steel, or concrete application where noise control is required. This includes wood framed, steel framed, CMU, or concrete wall or ceiling systems. The RSIC-1 assembly decouples the gypsum board from the underlying structure to provide enhanced acoustical performance. With an acoustical design load rating of 36 lbs. per isolator, the clip can support up to two layers of 5/8″ gypsum board when spaced no more than 24″ x 48″ O.C. The RSIC-1 clip fastens directly to the framing or structure to prevent sound and vibrations from entering the adjacent space. This improves the STC and IIC ratings of construction assemblies.

Frequently Asked Questions
RSIC stands for Resilient Sound Isolation Clip.
We have an installation guide for the RSIC clips.
Yes. The RSIC clips greatly enhance the performance of the insulation. When you just add insulation to a wall or ceiling without RSIC clips there is little change in the acoustical performance of the system. However, when the total decoupling (isolation) of the gypsum board from the structure is accomplished with the RSIC-1, the insulation becomes very important.
RSIC-1 clips are typically installed on one side of an assembly. Using RSIC clips on both sides of the wall will improve the STC by completely and totally decoupling the gypsum board from the structure. If the RSIC-1 is used on one side only, ideally the clips will be installed on the source side (noisy side) of the wall to keep the noise from getting into the structure.
The installation procedure of the RSIC clips is very easy. Just follow the installation guide.
STC (Sound Transmission Class) is a measurement that indicates how much noise is stopped (absorbed) by the wall or floor ceiling assembly (airborne or voice noise). IIC (Impact Insulation Class) is a measurement that indicates how much impact noise is stopped in a floor/ceiling assembly. STC and IIC are logarithmic, like the Richter scale. Each 10 points represents a doubling of the noise reduction capacity of an assembly.
You must use a hat channel (25 gauge, hemmed edge or 20 gauge with no hemmed edge). You cannot install the wallboard directly to the RSIC-1 clip.
The RSIC-1 clip is designed for use with various framing designs and applications. It will attach to wood, metal, CMU or concrete. All of the clips have multiple applications.
In head to head testing the RSIC-1 outperforms the old fashioned RC channel by 10 STC points and 7 IIC points. This reduction is a halving (reduced noise level by 50%) of the amount of noise you hear.
Yes. You need to seal all potential air leaks with non-hardening Acoustical Caulk to achieve the best Field Sound Transmission Class (FSTC) and Field Impact Isolation Class (FIIC) ratings. Use fire rated sealant where required. Enclose all recessed light fixtures with proper noise control design enclosures (fire rated when required). Seal all electrical boxes with Firestop Putty Pads. Evaluate the installation sequence to maximize noise control. Evaluate air ducts & air returns to ensure best FIIC and FSTC results.
A “lab” test is a very controlled environment. The field testing demonstrates how the product works in real world applications. The accepted filed variance between a lab test and a field test is 5 STC and IIC pts.
The RSIC-1 clip is the lowest cost highest performing acoustical UL Fire resistive design component available.
This is a common problem in condos and apartments. The “recommended” application of the RSIC-1 clips is to remove the existing ceiling, insulate the cavity, install AudioSeal Sound Barrier, seal the recessed lights, Firestop Putty Pads on the electrical boxes, then install a new gypsum ceiling with the RSIC-1 clips. If you don’t want to remove the existing ceiling the RSIC-1 retro can be used directly over the existing gypsum only if there is no other resilient product already in place. The best results will be realized with the removal of the existing gypsum board ceiling. The acoustical performance of the ceiling will be greatly enhanced using either of these applications.
The RSIC-1 is made with natural rubber which de-couples the framing structure from the gypsum board. This stops the sound vibrations from traveling to a different area. The rubber isolation of the RSIC-1 is very efficient in stopping noise transfer.
Yes.
The maximum acoustical design load is 36 pounds per clip.
Length = 3 inches Width = 1 1/4 inches Depth = 1 5/8 inches, with 7/8 inch hat track attached.
The “recommended” fasteners are as follows: Wood: 2 1/2 inch x 10 or 12 wood screw with a hex head. Steel: 1 5/8 inch x 10 or 12 steel screw for 25 ga. steel Steel: 1 5/8 inch x 10 or 12 self drilling screws for 20 ga. or stronger steel Concrete: 2 inch drive spike or tapcon fastener (min pull and sheer of 140 pounds) CMU: multiple choices, check with your local fastener supplier for a fastener that has a min 140 pounds pull and sheer design load.
