Advantages

  • Acoustic insulation achieved DnTA > 75 dBA.
  • Plastering ensures the tightness of the floor.
  • Mass-spring-mass system with absorption at low, medium and high frequencies.
  • The direct placement of plasterboard of 15 and SONODAN® PLUS increases the pre-slab insulation at low, medium and high frequencies.
  • The material in the first cavity dampens impulsive noises of low frequencies.
  • The membrane between boards displaces the resonance of the system towards less audible frequencies and improves isolation at low frequencies.
  • Mineral wool avoids the “drum” effect between boards.
  • The waterproof chamber may be the minimum allowed by the premises.
  • The spring acoustic hanger prevents excitations at low, medium and high frequencies.
  • Light system providing good results and speed of execution

    • Application

  • Musical premises with emission 100-105 dBA and night time: live music, discos, wedding halls, etc.
  • Music recording studios.

    Unit of Work

    Ceiling acoustic hanger system for the acoustic isolation of musical premises with emission up to 105 dBA formed by:
    Plastering of the roof; Direct placement of 15 mm plasterboard fixed to the roof by means of a structure with multilayer insulation for low, medium and high frequencies of 40 mm thickness, SONODAN® PLUS SELF-ADHESIVE mechanically fixed with 40 insulation fixing; Spring acoustic hanger attached to the structure through the plasterboard; structure of double profiles with mineral wool deposited on the structure of 70 kg/m³ density and 40 mm thick; placement of 12.5 laminated plasterboard fixed to the structure by means screws; 4 mm thick Danosa M.A.D.® acoustic membrane fixed to the board by means of staples; fixing to the structure of the second plasterboard of 12.5 mm thickness by means of screws, fully sealed and installed, ready to install decorative false ceiling.
