How To Install the QuietBox With Framing Member

Tools Needed

Positioning With Layers Of Drywall

Only the finish layer of drywall will overlay the QuietBox, all other layers will butt against the sides of the QuietBox.


Our QuietBox is sized to fit many different models of recessed light housings from various manufacturers including housings that use LED, incandescent, low voltage, and CFL bulbs. We only approve use of IC rated housings within our QuietBox. Non-IC rated housings are prohibited from being installed inside our QuietBox. Non-IC rated housings will generate a significant amount of heat which will in turn cause the bulb to either overheat and shut off or possibly spark a fire. DO NOT use a non-IC rated recessed light housing inside the QuietBox. If you do not know if your housing is IC rated or non-IC rated then contact the manufacturer or replace the housing entirely with an IC rated housing.

Seriously, NO non-IC rated housings allowed.

    Attach QuietBox To Joists Using Common Framing Member

    1. Attach 2x Framing Member To Joists and QuietBox

      Measure the width between the two joists where you will install the QuietBox and cut a 2x framing member, or block, to fit tight. Screw or nail in the block so it is firmly attached. Then attach the QuietBox to the block. Most installations will require mounting the QuietBox flush to the bottom of the joist. For multiple layer assemblies, install the QuietBox flush to the back of the finishing layer. The QuietBox may be able to rock a little on the end opposite the block. This is entirely normal and not a problem at all. For full stability you can attach a block on both ends, but this will increase the connections to the joist and not help the performance of the QuietBox in any way.

    2. Attach Hook Side of Velcro and Run Electrical

      Our universal QuietBox design requires the use of Velcro to attach your recessed light housing to the inside of the QuietBox. Each QuietBox comes with a piece of Velcro long enough to cover one width side and one length side of the QuietBox. Remove the release paper from the hook side of the Velcro and attach it to the inside of the QuietBox as drawn above. Then pull your wire(s) through the pre-drilled hole. Make sure to leave enough slack to wire the housing.

    Prepare IC-Rated Recessed Light Housing

    The recessed light housing models that fit our QuietBox are the new construction housings. Not all housings are the same, but they generally have two attachment arms that are held to the housing by small tabs that can be twisted or pulled apart using a pair of pliers. Take this step to remove both attachment arms from the housing. Then use your pliers or a hammer to compress or smash any obstructions that would keep one width side and one length side from being flush. It is important to make two sides flush so when you attach the hoop side of the Velcro to the housing you will have a quality seal between the Velcro and the housing.

    Attach and Wire Housing To QuietBox

    1. Attach Velcro to the Recessed Light Housing

      Remove the release paper on the hoop side of the Velcro and attach the adhesive to one width side and one length side of the housing.

    2. Wire the Housing and Attach to the QuietBox

      Connect the electrical to the recessed light housing and attach the Velcro loop on the housing to the Velcro hook inside the QuietBox. Depending on the size and weight of your recessed light housing, one side of the housing might be able to move a little. This is not a problem at all. The Velcro has been designed specifically for this purpose and will fully support the housing long enough for the drywall to be hung. After the drywall is hung the drywall and trim kit will hold the housing in place permanently.

    Seal and Overlay QuietBox

    1. Apply Acoustical Sealant

      Apply sealant to fill the wire hole and along the bottom of the QuietBox frame before overlaying with drywall. For multiple layer assemblies, apply the sealant along the outside perimeter where the drywall will butt against the side of the QuietBox.

    2. Install Drywall

      Mount the drywall to the ceiling framing or channel. If multiple layers are installed then butt the additional layers to the sides of the QuietBox with the finish layer overlaying the QuietBox.
