Advantages

  • Shifts the system’s resonance frequencies to less audible frequencies.
  • The acoustic membrane improves low-frequency insulation in the plasterboard system.
  • Absorptive for mid and high frequencies.
  • The membrane is fixed to the back of the plasterboard.
  • Acoustic membrane functions as a vapor barrier.
  • Its thermal and acoustic insulation capacity can be increased by increasing the thickness of the structure and mineral wool.
  • Lightweight system with good planarity, thinner profile, and faster installation.

    • Application

  • Rehabilitation of existing vertical partitions.
  • Lightweight backing with minimal thickness.
  • Thermoacoustic improvement of vertical partitions

    Unit of Work

    Thermoacoustic backing system consisting of:

    Metal structure on a double-layer anti-resonant band FONODAN® 50, arranged peripherally on the metal structure of the backing. Absorbent material placed inside made of mineral wool with a density of 70 kg/m³, a 15 mm thick gypsum board over an acoustic membrane finished with a 10 kg/m² aluminized film and 5 mm thick M.A.D.® PRO 100, fixed to the structure with self-tapping screws.
