Partition wall

  • 1 12.5 mm plasterboard
  • 2 M.A.D.® acoustic insulation
  • 3 12.5 mm laminated plasterboard
  • 4 Plasterboard structure
  • 5 15 mm plasterboard
  • 6 Rock wool acoustic insulation

Advantages

  • Airborne noise insulation DnTw between 55 - 65 dB
  • Shifts system resonance frequencies to less audible frequencies
  • The acoustic membrane improves the insulation at low frequencies of the laminated plaster system
  • Absorbent at medium and high frequencies
  • The fifth plate ensures the tightness of the system to recessed installations
  • Its thermal and acoustic insulation capacity can be improved by increasing the thickness of the structure and mineral wool
  • Light system better for structural strength with low thickness and faster execution
  • Application

  • Gyms
  • Cinemas
  • Radio studios
  • Auditoriums, theaters, music schools: central buildings and music booths
  • Graph
