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.

Clips can be ordered per piece or in discounted packs of 10. When buying per pack, screws are included for installation.

Product Data

How it Works:

RSIC-1 and Hat Channels 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).

• Fasten RSIC-1 to the substrate with a fastener approved for a minimum pull-out and sheer of 120 lbs

(see above for details). Comply with Layout Details above.

• Ensure the internal metal ferrule is tight to the substrate.

• Snap in the drywall furring channel (hat track) into the RSIC-1 clips (horizontal for walls).

• Place 1/4” (minimum) shim on floor to fully support the gypsum board.

• Install the gypsum board from the bottom up leaving a 1/4” min. gap around the perimeter of the wall.

• ONLY remove the shims after ALL the gypsum board is completely screwed to ALL the drywall furring channels.

Make sure every screw (floor to ceiling and wall to wall) is installed as required by the assembly design, in every layer of gypsum board before removing the shims at the floor. The shims are critical to ensure best results.

• Caulk around the entire perimeter of the gypsum board and seal all potential noise leaks, such as around electric boxes. Use fire and smoke rated Acoustical Sealant where required.

Important Notes:

• When attaching the RSIC-1 clips to a steel stud the minimum allowable thickness is 20 gauge. (0.030).

• Resilient Sound Isolation Clips, furring channel (hat track) and gypsum board shall not carry heavy loads such as cabinets or bookshelves.

Comments about RSIC-1 - Resilient Sound Isolation Clip:
We built a recording/mixing facility in a concrete slab factory building. I wanted to save space (space=money) and keep transmission loss between our rooms as high as my budget would allow. We wanted to build rooms within rooms but build complexity and code restrictions here complicate that approach. RISC clips solved many problems. Instead of supporting walls and ceiling on a massive floating floor, we could simply pound up floor to ceiling studs for both inner and outer walls. A grid for the ceiling was suspended from the building slab above, not resting upon inner walls. RISC Clips (with hat channel) decouple the inner walls from the building and from each other. No touches at wall/ceiling/floor joints, everything sealed with caulk. Performance is remarkably good and the construction is relatively straight forward (important depending on contractor!). We used metal studs spaced at 24 inches and followed recommendations for enough clips to support 3 layers of 3/4 sheetrock. We put up only 2 layers (with greenglue between), the extra load capacity allows for lights and other devices to be attached to walls without overloading the clips. After two years we are still very satisfied with our walls and ceiling performance. RISC clips fit our needs very well. I give only 4 stars for two reasons. With metal studs our guys had trouble mounting the clips tightly without stripping out a hole in the studs. We cut lots of small pieces from 1/2 inch plywood which we held to the back side of the stud while screwing regular construction screws through each clip, through the stud, and into the wood behind. It took more labor, especially to cut the pieces of wood, but all clips were mounted very solid and secure, no worries that screws could pull out later. The manufacturer's test data shows that transmission loss with their clips will not be excellent below something like 150 Hz. Our walls seem to perform just about exactly as the test data shows. It is possible to hear a little thumping or subway rumble from time to time. That said, the clips actually perform better than I had expected. I will use RISC clips again without hesitation.
Bottom Line Yes, I would recommend this to a friend

Comments about RSIC-1 - Resilient Sound Isolation Clip:
Our beach rental houses often have bedrooms on a level beneath common rooms, which can be disruptive for early or late sleepers. These clips, especially when combined with rockwool and mass-loaded vinyl, do a very good job of sound isolation across a wide range. The price is rather steep for the material involved, but they certainly work as advertised.

Customers Questions and Answers

1) Gwen: Hi, I need to soundproof a barn style building which has exposed trusses. I do not want to lose the height and pitch of the ceiling and so have opted to soundproof the roof by building another roof over the existing roof . My question pertains to decoupling. How would I go about decoupling the soundproof material over the roof? I'll be using clips and hat channels on the interior walls, but I'm not sure if I will need to/or how to apply this method on roof. I can send more info if need be. Your advice would be appreciated. Thanks, Gwen

Trademark Soundproofing Reply: Hi Gwen, I am a bit confused as to to the method that you will be building. As far as the clips and channels on the ceiling the method is similar to installing them on the walls. The clips are attached to the bottom face of the ceiling joists, channels are snapped into the clips and the drywall is attached to the channels.

2) Dave F: Hi I've completed the first layer of drywall on my project following the instructions for the RSIC-1. I am wondering now, before I put up the second layer, whether I should be staggering the sheets of drywall. I didn't do that on the first layer so I have quite long butt joints across the walls and ceilings. It's more work to stagger, but I thought I would ask. Thanks, Dave

Trademark Soundproofing Reply:

Hi Dave. You just need to stagger the 2nd layer relative to the first layer (so that the 2nd layer overlaps the seams of the first layer) however you do not need to stagger the 2nd layer itself. If you are still concerned you can run a bead of acoustical caulk in the seams which is easier than staggering.

3) ZM: One more question, about finishing: The instructions on installing such clips suggest leaving a gap around perimeter of wall or ceiling, of around 1/4" or so, and then filling that with flexible caulk (acoustic sealant). However, how should the contractors then finish those corners? I assume the goal is to maintain flexibility at the corners to allow the RSIC-1 clipped wall or ceiling to move and flex slightly, and thus absorb sound. Presumably the contractor cannot paint right on the acoustic sealant. Should the contractor use some special compound at the corners? Or a flexible corner moulding? My contractors were thinking to just use normal compound (plaster), but I am concerned that this would create a rigid connection, which would compromise the resilient clip design sound isolation. Thank you for any clarification, and for the prompt and excellent service! (We've also been ordering the buckets of GreenGlue from you, but via your Amazon store)

Trademark Soundproofing Reply: The acoustical caulk can actually be painted on once it dries (48 hours). However usually corner beads and drywall compound is used to finish the corners and that does not compromise the decoupling in any way. We appreciate your business, Thank You!

4) Scott J: What is the height of the RSIC clip coupled with the hat channel?

Trademark Soundproofing Reply: An inch and 5/8

5) Richard W: I am doing a home theatre ceiling, 15'x25' with a 4'x10' bump out in the center of one sidewall, making a total of 415 sq feet, by my calculations using the 24" oc x 48" oc layout in the installation guide, I am thinking 62 sic clips will do it am I correct? because I would like to order some and not have to order twice, thank you

Trademark Soundproofing Reply: Hi Richard. 23 percent of the square footage is usually the magic number. Which would be 95 clips. Thank you.
