Acoustic Insulation


Noise protection



  • DnTw airborne insulation between 50 and 62 dB
  • L’nTw impact noise level between 58 and 42 dB
  • Insulation system certified with DIT 439 / R16
  • Impact noise level towards the upper floor L’nTw < 40 dB
  • Extended Durability
  • Compressive strength
  • Minimum thickness
  • Easy to adapt to the installations
  • Does not need a vapor barrier layer
  • CONFORDAN® 900 improves the loudness of the laminate flooring and gives an extra improvement to impact noise
  • Application

  • Public buildings like hotels.
  • Private residential buildings.
  • Teaching buildings: schools, universities, nurseries.
  • Administrative and corporate buildings.
  • Sanitary buildings: hospitals and residences.
  • Local daytime hours: cafes, restaurants, bars.
