Noise protection

Independent wall


  • Airborne noise insulation achieved at R’A,tr > 63 dB, giving sufficient isolation to meet the levels of emission in common areas.
  • The ARGOCOLA ELITE 500 when applied on two sides ensures the fixation of the ACUSTIDAN®, the waterproofing of the wall and its acoustic tightness.
  • Combined absorption into cavity at low, 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 mineral wool.
  • Light system providing better results with low thickness and faster execution.
  • Application

  • Premises with sound emission between 85-90 dB and nighttime: breweries, restaurants, cocktail bars.
  • Classroom of music in schools.
  • Music schools: individual instrument booths.
  • Clubs in shopping centers.
  • Graph

    Unit of Work

    Solution for the acoustic isolation of premises with sound emission between 85 and 90 dBA and nighttime formed by:
    Bilayer insulation at low frequencies of 20 mm thickness, ACUSTIDAN® 16/4 sticking double-sided with ARGOCOLA ELITE 500 and fixed with insulation fixings of 40; 50 mm plasterboard structure with mineral wool between studs of 70 kg/m³ density and 40 mm thick, placement of 12.5 plasterboard fixed to the structure by means screws and sealed; 4 mm thick Danosa Acoustic Membrane, M.A.D.® 4 stapled to the first board; fixing to the structure of the second plasterboard of 12.5 mm thickness by means screws, fully sealed and installed, ready to install the finish.
