Advantages

  • Acoustic insulation achieved DnTA > 60 dBA.
  • Plastering ensures the tightness of the system.
  • Mass-spring-mass system with medium and high frequency absorbing.
  • FONODAN® 900 or M.A.D® 4 between boards shifts the resonance frequencies of the system towards less audible frequencies.
  • Its thermal insulation capacity can be improved by increasing the thickness of the mineral wool.
  • The cavity may be the minimum allowed by the premises.
  • The rubber acoustic hanger prevents excitations of mid-low, medium and high frequencies.
  • Light system better for structural strength and faster execution.
  • Application

  • Sound emission premises 80-90 dBA with daytime: coffee shops, restaurants, bars, nurseries.
  • Theaters, auditoriums, music schools: central building and teaching classrooms.
  • Commercial basses: supermarkets, printers, workshops and builders.
  • Cinemas.
  • Radio studios.
