What Is A QuietBox?
A QuietBox is used to isolate sound from passing through your recessed lighting. The QuietBox is designed to maintain the acoustic rating of your ceiling while allowing you to use attractive lighting in your room.

The QuietBox 6″ version is made to fit the Halo 6″ H7ICT and Halo 6″ H7ICAT recessed lighting housing. The QuietBox 5″ version is made to fit the Halo 5″ H5ICT and Halo 5″ H5ICAT recessed lighting housing. The QuietBox 4″ version is made to fit the Halo 4″ H99ICT recessed lighting housing. These models are the basic recessed lighting housing with connector arms (for new construction) that you would find at any Home Depot or Lowe’s hardware store.
The exterior frame of the QuietBox is 3/4″ MDF and the interior layer is 1/2″ drywall. Sandwiched between these two materials is the renowned Green Glue. We have applied Green Glue at a rate of about 1 tube per 10.6 square feet which is in line with what we call the Supreme application level of Green Glue. Otherwise known as 3 tubes per 4′ x 8′ sheet. The angles of the MDF box are sealed with SilenSeal (Green Glue Noiseproofing Sealant) and the angles of the drywall layer are also sealed with SilenSeal. A hole is pre-drilled to allow for electrical wiring to pass through and a small piece of MetaCaulk Putty Pad is included with the box to seal the hole after passing the wire through during installation. Installation of the QuietBox requires the use of (2) RSIC-DC04 clips to attach directly to the joists. These clips are included with each QuietBox as well.
This product is manufactured in house by the employees of Sound Isolation Store and is available exclusively by Sound Isolation Store. With this we guarantee the quality of construction including the materials used to construct the box, the methods used to construct the box, and the ease of installing the QuietBox. As long as you use the specified Halo recessed light then you will be successful.
OPTION TO INCLUDE A LIGHT IN YOUR QUIETBOX
We also provide an option to include the actual light with your QuietBox. For this we include a fully functional recessed light with the extension arms removed and prepared for installation in the QuietBox. Your price for the customized version of the Halo light is about the same as what you can buy the light for from Home Depot or Amazon. This makes installation quicker and extremely simple.
Does the QuietBox Work?
The QuietBox definitely does allow you to use recessed lighting in your ceiling without reducing the acoustic integrity of your ceiling. The QuietBox is made of 3/4″ MDF which is a very thick and dense material that provides a significant amount of mass to improve isolation. The product that really helps the QuietBox isolate sound is Green Glue. The Green Glue is applied liberally at a rate that is the equivalent of 3 tubes per 4′ x 8′ sheet of material.
If you are using double layer drywall and Green Glue on your ceiling then the QuietBox will perform as well as your ceiling. If you are installing sound clips on your ceiling then the inclusion of the RSIC-DC04 clips will help maintain a consistency in your theme of decoupling. In terms of sound isolation, think of the QuietBox as an extension of your ceiling. The level of performance the QuietBox provides will in no way negate the isolation performance of your ceiling.
How Do I Install A QuietBox?
Our QuietBox is attached directly to your joists using RSIC-DC04 clips. These RSIC-DC04 clips are included with each box and very easy to attach to both the joist and the QuietBox. The attachment of the QuietBox is very simple, but does require electrical work to bring power to the recessed light. We can only provide installation help in regards to the box itself.
