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. Simply sandwich the WallDamp material between two pieces of 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.
WallDamp is 1mm thick in 4x4” squares and 1½” x 4’ strips. It is covered with high strength double sided adhesive which is protected by easy to remove release paper to ensure a lifetime of dependable performance.
How Many Do I Need?
Calculating quantity is easy: 1 square foot surface area = 1 Walldamp Square.
A 12x10x10 room would be calculated as follows:
- Surface Area = 2×(12×10 + 12×10) + (10×10) = 580 feet (front, back, side walls and ceiling)
- You would need about 600 squares (with margin for error) if you were treating, so 2 MEDIUM packages.
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.
- Size (each square): 4" x 4" x 1/16" thick
- Weight (per bundle of 25): 2.2 pounds (1 kg)
- Material: viscoelastic polymer
- Coverage: one WallDamp Square per square foot of surface
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.
Quick & Easy During Construction and Renovation
- Double sided adhesive for easy application
- Fasten between two layers of strong, flexible material
- New construction: place on studs, joists, top plates, bottom plates
- Install over existing drywall, then install another layer of drywall!
- Retro construction option: place on furring strips, underneath drywall
- Exterior sheathing: place between studs and sheet
- Use one Square for each square foot of surface to be damped
