Pot light backer boxes are 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 Pot light backer boxes is to restore this lost mass created by the recessed light housing by fitting the entire housing within the Pot light backer box and sealing the Pot light backer box to the back of the finish layer of drywall. Normal drywall ceilings will have the Pot light backer box installed using a 2x framing member or similar while resilient ceilings will remain decoupled by attaching the Pot light backer box with the Hush isolation clips. Installation of the Pot light backer box 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 Pot light backer box is finished with 5/8″ Type-X drywall and UL rated acoustical sealant. The Pot light backer box meets building code requirements for electrical fire code. The height of the Pot light backer box allows enough space above each of the compatible housings listed under the Compatibility tab.
