November 1, 2024: Genuine RSIC-1 Clips are now painted red.
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, 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.
Please refer to the installation guide in the documents section of this page.

The RSIC-1 Clip is an essential solution for achieving superior sound isolation in a variety of settings. Designed to decouple drywall from framing structures, these resilient sound isolation clips effectively reduce both airborne and structure-borne noise. Common applications include:
Whether for new builds or retrofits, RSIC-1 Clips seamlessly integrate with resilient channel drywall systems and ceiling applications.
RSIC-1 Clips offer several key benefits for projects requiring effective noise isolation:
By creating a floating wall or ceiling assembly, RSIC-1 Clips deliver significant improvements in STC and IIC ratings.
Achieve professional-grade results without the need for expensive structural modifications.
Compatible with wood, steel, and concrete structures, as well as single or multiple layers of drywall.
Manufactured with recycled content and treated to minimize VOC emissions, making them safe for sustainable construction.
RSIC-1 Clips integrate with standard resilient channels, making them straightforward to install for contractors and DIY enthusiasts alike.
Featuring zinc-electroplated steel and high-quality neoprene, these clips are built to last while maintaining top acoustic performance.
By addressing both vibration control and airborne noise reduction, RSIC-1 Clips are ideal for a wide range of sound isolation projects.
While traditional resilient channels have long been used to improve noise isolation, RSIC-1 Clips take performance to the next level. Here’s why:
When combined with other acoustic treatments like Green Glue Damping Compound or AudioSeal® Mass Loaded Vinyl (MLV) Soundproofing Barriers, RSIC-1 Clips offer unparalleled soundproofing for walls and ceilings.
The RSIC-1 Clip functions by decoupling the gypsum board from the supporting structure, breaking the direct path of sound vibrations. Here’s a closer look at how this innovative clip achieves its sound isolation capabilities:
A natural neoprene isolator absorbs vibrations, preventing structure-borne noise from transferring to adjacent spaces.
RSIC-1 Clips hold the resilient channel in place, creating a "floating" layer of drywall that blocks airborne noise.
By minimizing sound bridges, RSIC-1 Clips significantly enhance STC and IIC ratings for walls and ceilings.
The clips support up to two layers of 5/8" drywall, offering flexibility for various levels of noise control.
The result is a quieter, more comfortable environment, even in challenging noise-sensitive spaces like multi-family housing and commercial buildings.
The RSIC-1 Clip is engineered to deliver measurable improvements in noise isolation. When integrated into wall or ceiling assemblies, the clips provide:
When paired with resilient channels and additional materials like mass-loaded vinyl, RSIC-1 Clips provide an unmatched soundproofing solution for residential, commercial, and industrial projects.
What does RSIC stand for?
RSIC stands for Resilient Sound Isolation Clip.
How do I know where to place the RSIC clips and how many will I need for my project?
We have an installation guide for the RSIC clips.
Do I need to use insulation along with the RSIC clips for better noise control?
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.
Do I need to place RSIC-1 on both sides of the wall?
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.
Are RSIC-1 clips hard to install? I don't want to short circuit the system during installation.
The installation procedure of the RSIC clips is very easy. Just follow the installation guide.
What are STC's and IIC's and how do they work?
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.
Do I have to use Drywall Furring Channel (Hat Track) with the RSIC-1 or can I connect the wall board directly to the RSIC-1 clip?
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.
There are many different types of RSIC clips on the website. How do I know which is the correct one to use on my project?
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.
What is the performance difference between the RSIC-1 clip and Resilient Channel? Will I be able to tell the difference once it is installed?
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.
Once I install the RSIC-1, do I need to do anything else to help the noise isolation?
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.
What is the difference between the lab STC's and IIC's versus the field STC's and IIC's?
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.
How does the RSIC-1 assembly compare to other wall and floor-ceiling assemblies?
The RSIC-1 clip is the lowest cost highest performing acoustical UL Fire resistive design component available.
I can hear a lot of noise from the people on the floor above me. Is there an easy solution to reduce the noise?
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.
How does the RSIC-1 work?
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.
Does the RSIC-1 work on both wall and floor-ceiling assemblies?
Yes.
What is the maximum load for each clip?
The maximum acoustical design load is 36 pounds per clip.
What are the dimensions of the RSIC-1?
Length = 3 inches Width = 1 1/4 inches Depth = 1 5/8 inches, with 7/8 inch hat track attached.
What type and size of fastener can I use?
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.
