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.

QuietBox for Recessed Lighting

The QuietBox is used to isolate IC rated recessed lighting for nearly every brand and style of housing. Each untreated recessed light in your ceiling will lower the performance of your assembly by 1-2 STC points, depending on the number of lights and size of ceiling. This reduction in performance is due to the loss in mass where the recessed light is installed in place of one or more layers of drywall on the rest of the ceiling. The concept of the QuietBox is to restore this lost mass created by the recessed light housing by fitting the entire housing within the QuietBox and sealing the QuietBox to the back of the finish layer of drywall. Normal drywall ceilings will have the QuietBox installed using a 2x framing member or similar while resilient ceilings will remain decoupled by attaching the QuietBox with the GenieClip LB clips. Installation of the QuietBox around your IC rated recessed light will restore the lost mass entirely allowing your ceiling to reach the full STC, OITC, and IIC rating.

The interior of the QuietBox is finished with 5/8″ Type-X drywall and UL rated acoustical sealant. The QuietBox meets building code requirements for electrical fire code. The height of the QuietBox allows enough space above each of the compatible housings. Click over to our product page on our site to view a list of compatible housings.


The QuietBox is sound tested to show zero loss in ceiling assembly performance when the QuietBox is installed over the recessed light housing. Average loss from untreated recessed light is 1-2 STC points depending on the number of lights and size of the ceiling. The final rating of the QuietBox will be equal to any ceiling assembly with triple layer drywall and a damping compound.
