SOUND ISOLATION WALL AND CEILING - SSP DRYWALL MOUNTING CLIP

     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.

Tested Composite Wall Constructions per ASTM E90 and ASTM 413 at Riverbank Labs. Wood Stud partition. 2 x 4, 16” O.C. with 5/8” gypsum board, one layer each side. R19 fiberglass in cavity. SSP clips and 7/8” furring channel. (* +7 STC improvement compared to the same wall with resilient channel. Find details in our report SSP Clip vs. RC.)   Wood Stud partition. 2 x 4, 16” O.C. with 5/8” gypsum board, one layer one side, two layers on opposite side. R19 fiberglass in cavity. SSP clips and 7/8” furring channel. Wood Stud partition. 2 x 4, 16” O.C. with 5/8” gypsum board, two layers each side. R19 fiberglass in cavity. SSP clips and 7/8” furring channel.   Resilient Sound Isolation Wall and Ceiling Clip Model SSP Benefits: Highly effective sound control at lowest installed cost.   Quick and easy to install with standard drywall furring channel.   Weight capacity - 50 lbs. per clip maximum.   Maximizes available occupied space with low-profile design.   Performance range of STC 57 to STC 64 per laboratory tests, a substantial improvement vs. resilient channel.   Eliminates problem of hard attaching that is common with resilient channel.

   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 pads are 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.
