Independent wall

Advantages

  • Airborne noise insulation achieved at R’A,tr > 67 dBA, giving sufficient isolation to meet the levels of emission in common areas.
  • The plastering ensures the impermeability of the wall and its acoustic tightness.
  • Combined absorption into cavity at low, medium and high frequencies.
  • Insulation to low frequency impulse noise.
  • The resonance frequencies of the system are shifted to less audible frequencies.
  • The acoustic membrane improves the insulation at low frequencies of the plasterboard system.
  • Its acoustic insulation capacity can be improved by increasing the thickness of the chamber.
  • Light system providing better results, with low thickness and faster execution.

    • Application

  • Machine rooms in residential buildings: hotels, hospitals, teachers and offices
  • Music venues: pubs, karaokes, discos, party rooms, wedding halls...
  • Music recording studios
