Advantages

  • Acoustic insulation achieved DnTA > 70 dB.
  • Plastering ensures the tightness of the floor.
  • Mass-spring-mass system with absorption at low, medium and high frequencies.
  • The chamber material dampens impulsive noises of low frequencies.
  • The membrane between boards displaces the resonance frequencies of the system towards less audible frequencies and improves isolation at low frequencies.
  • Its thermal insulation capacity can be improved by introducing mineral wool.
  • The cavity may be the minimum allowed by the premises.
  • The spring acoustic hanger prevents excitations of low, medium and high frequencies.
  • Light system providing better results and speed of execution.

    • Application

  • Machine rooms in residential buildings: hotels, hospitals, teachers and offices.
  • Music venues: pubs, karaokes, party rooms...
