NEW! SOUND ISOLATION  DRYWALL CLIP AERO-SUPPORT (AS-1) Drywall mounting hardware reduces wall “build-out”.

Resiliently mounted wall Gypsum board (Drywall/ Sheetrock/ Wallboard) is now a industry standard for  reducing   sound transfer between walls in rooms.  The AS-1 Sound Isolation Mounting Clip (SIMC) is used with Furring Channel (DWFC) in order to mount these drywall panels.  This clip has several molded neoprene grommets that provides high sound insulation between the panel and the framing.  Slots and holes in the flanges can mount the DWFC in a variety of positions, eliminating the need for costly special brackets or time consuming furring-out blocks.

For existing wallboard, a slot is cut to insert the unused leg then mounted &  fastened over the stud. Call us to discuss what to do about the “Resonant Chamber” created.



Build out of the clip/channel assembly can be less than 1/4″ over the face of the DWFC past the framing member.   (see below) or built out even more as desired to straighten uneven framing.

MLV may be  placed over clips with sound isolation tape installed.

The rubber mounting grommets used are unique “Pull-Down” units designed to lock the clip in place by compressing the rubber.  Depending on the application, not all three grommets are needed.

It mounts with  drywall screws (or other fasteners 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 used for every four to eight sq. ft. of wallboard area.  A typical 8′ wall  would have AS-1 clips  mounted to the studs in three horizontal rows  with fasteners, one row a few inches from the top and another few inches from the bottom and another in the middle.     2″  Neoprene 3/8″ thick  Vibration pads are spaced every 2′ on the floor to support the edge of the new drywall panels.  The drywall panels are then attached to the DWFC  vertically with drywall screws in the normal manner.  A gap must be provided where the walls meet the ceiling and other walls and sealed with a full load of acoustical caulk. Since the full weight of the drywall is not hanging from the DWFC, but is simply balanced there, (supported by the Neoprene pads),  the loading on the clips rubber mountings is much less, improving the sound reduction dramatically.

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 gap left by the vibration pad.  Adding one layer of 5/8″ Fire Code Drywall in this manner will double or triple the sound reduction of the existing wall.  More sound reduction would be obtained by adding more sound control elements into the project.  (Green Glue, etc).

These clips can be used to add a floating wall to a  wall where the existing drywall needn’t be removed.

Ceilings would be  similar to the above. However, due the fact we have not completed testing on the load handling capabilities of the clips, we don’t recommend using them for hanging ceilings at this time.
