In-Wall Bass Absorption & Isolation

Available 25 self-adhesive sheets per bundle.

One bundle covers 25 square feet of wall or ceiling surface.  Simply add a layer of drywall over top of your existing walls with WallDamp compressed between.

WallDamp is a truly innovative tool for cleaning up the lowest octaves of the audio range without occupying any floor or wall space.

Integrated into the wall construction, WallDamp rapidly converts the motion of vibrating sheets into heat through dissipation of shear stress forces.

You can sandwich the WallDamp material between two any pieces of structural sheet goods, screw it all together, and you now have constrained layer damping and better isolation and control of subwoofer bass.



WallDamp is a self-adhesive sound and vibration damping material. Apply between drywall, studs, and joists in residential construction projects to produce quieter and calmer homes, reminiscent of those lath and plaster homes but at a fraction of the cost.

    Benefits

    WallDamp Acoustic System

    • Calm thundering/shuddering walls and ceilings
    • Turn your room surfaces into large membrane bass traps
    • Isolate subwoofer-range sound
    • Improve bass dynamics and musicality
    • Built-in molecular adhesive improved performance and simplifies installation

    Blocks Sound Conduction

    Add WallDamp between the stud/joist and drywall to block the conduction of sound the stud of the wall and add sound-absorbing insulation in the wall cavity to help absorb the conduction of sound through the air between the studs. WallDamp weighs 1/3rd the density of steel. Because of the difference in material density WallDamp reflects sound and because of its absorption properties, it absorbs sound being conducted between one side of the wall to the other.

    Eliminates Sound Transmission

    Add WallDamp between studs and drywall to dampen the otherwise free vibration of the drywall that is suspended between the studs. Ever knock on the wall to find the stud? That hollow sound between studs is the bending vibration of the drywall and is what transmits sound through the wall. WallDamp on the stud face is distorted by this vibration action and absorbs energy out of the vibration. Add Walldamp between adjacent layers of double drywall to dramatically dampen drywall vibration.

    Eliminates Wall and Ceiling Shudder

    A wall shudders when people walk across the wood floor or close a door. The ceiling shudders from overhead footfall. But when the subwoofer of a home theater or hi fi set is playing, the walls, ceiling, and even the floor will be set into sympathetic vibration. That’s why people in other parts of the house or even next door “turn the bass down”. Adding WallDamp between studs/joists and drywall and between adjacent layers of drywall absorb the energy of vibration and virtually eliminate wall shudder.

      Testing
      The following test was conducted by Architectural Testing, Inc. The baseline construction was 1/2" gypsum attached to both sides of 2x4 lumber studs built 16" on center. The two scenarios tested indicate the relative benefits of applying damping between the studs and the drywall versus between two layers of drywall. The optimal system would have damping applied at both locations. Clearly, the sound isolation benefits of WallDamp are most pronounced in the lowest audio octave.
      Setup

      Quick & Easy During Construction or Renovation

      Each sheet is 4” x 4” x 1/16” thick, double sided adhesive and release paper.

      1. Apply one sheet per square foot to wall or ceiling.
      2. Remove release paper from one side, apply to existing sheetrock on one-foot centers.
      3. Press in place with 4” hard rubber roller.
      4. Remove second layer of release paper.
      5. Immediately apply second layer of sheetrock with the long dimension vertical, sheetrock screws as usual.
