How To Install the QuietBox With Corner Brackets

Tools Needed

tools used to install quietbox with corner brackets

Positioning With Layers Of Drywall

position quietbox in relation to drywall layers

Only the finish layer of drywall will overlay the QuietBox, all other layers will butt against the sides of the QuietBox, this includes any drop from resilient channel or resilient clip systems. In all assemblies, the Corner Bracket should be flush with the bottom of the joists, only the QuietBox positioning will change. For example, single layer drywall, QuietBox should be flush with the joists. Double layer 5/8" drywall, the QuietBox should be 5/8" below the joists. GenieClip RST system plus double 5/8" drywall, the QuietBox should be 2-1/4" below the joists (1-5/8" for GenieClip RST system plus 5/8" drywall of first layer).

Disclaimer

Our QuietBox is sized to fit many different models for soundproofing recessed lights 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.

Attach QuietBox To Joists Using Our Corner Brackets

  1. Attach Corner Brackets and QuietBox to the Joists

    attach quietbox with corner brackets to joists

    Attach the each Corner Bracket flush to the bottom of the joist (3 screw hole side to the joist) and then to the QuietBox (4 screw hole to the QuietBox). Most installations (one layer of drywall) will require mounting the QuietBox flush to the bottom of the joist as well. For multiple layer assemblies, or decoupled assemblies (resilient clips or resilient channel), install the QuietBox flush to the back of the finishing layer. The QuietBox might rock a little on the corners that do not have the Corner Brackets installed. This is entirely normal and not a problem at all.

  2. Attach Hook Side of Velcro and Run Electrical

    adhere hook velcro to quietbox

    Our universal QuietBox design recommends 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. Any type of housing or other opening that fits within the QuietBox dimensions is okay. 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

    attach and wire housing to quietbox

    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

    wire the light 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 acoustical sealant around quietbox

    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

    install drywall to cover the quietbox

    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.
