Resiliently mounted wall and ceiling Gypsum board (Drywall/ Sheetrock/ Wallboard) is fast becoming an industry standard for reducing sound transfer between rooms. (Soundproofing Rooms).
The SSP Sound Isolation Mounting Clip is used with Drywall Furring Channel (DWFC) in order to mount drywall panels. The clip has a molded neoprene element that provides high sound insulation between the panel and the framing. Metal ends provide sturdy support.
Build-out of the pad/channel assembly is 1-1/2″
It mounts with screws (or other fastener appropriate to the material to which it’s mounted), providing a low-profile sound control system that is low-cost and simple to implement.
One mount is required for every four sq. ft. of wallboard area. A typical 8′ wall would have SSP clips mounted to the DWFC creating three horizontal rows, one a few inches from the top and one few inches from the bottom and another across the middle. 2″ Neoprene 3/8″ thick Vibration padsare spaced every 2′ on the floor to support the edge of the drywall panels. The panels are then attached to the DWFC with drywall screws in the normal manner. A gap must be provided where the walls meet the ceiling and other walls and sealed with acoustical caulk
The gap at the floor is sealed either with lots of caulk and/or with “Backer Square” to reduce the amount of caulk needed to seal the large gap left by the vibration pad. Adding one layer of 5/8″ Fire Code Drywall in this manner will more than double the sound reduction of the existing wall. More sound reduction would be obtained by adding more sound control elements into the project.
Ceilings are handled similar to the above. Installation details are the same as for other clips.
