Layer Details

• Honeycombed damping material

  Just like the acoustic foam inside a loudspeaker, the honeycombed damping material attenuates the speaker back wave and thus increases the speaker performance.

• Aluminum sheet

  Aluminum provides rigidity to the Butyl/foam couple. This rigidity also permits the easy laying of BAM in difficult locations.

• Viscoelastic complex

  Self-adhesive, the Butyl complex absorbs the vibrations of the surface with which it’s in contact. It highly attenuates the outside noise that gets inside the car.
