Noise protection

Independent wall


  • Airborne noise insulation achieved at R’A,tr > 60 dB, giving sufficient isolation to meet the levels of emission in common areas.
  • The plastering ensures the impermeability of the wall and its acoustic tightness.
  • Absorbent at medium and high frequencies.
  • Shifts system resonance frequencies to less audible frequencies.
  • The acoustic membrane improves the insulation at low frequencies of the plasterboard system.
  • Its thermal and acoustic insulation capacity can be improved by increasing the thickness of the structure and mineral wool.
  • Light system providing better results, with low thickness and faster execution.
  • Application

  • Local daytime hours: cafes, restaurants, bars.
  • Places of public attendance: auditoriums, cinemas.
  • Commercial basses: workshops, builders.
  • Discotheques in isolated buildings.
