Advantages

  • Airborne noise insulation DnTw > 50 dB
  • Plasterboard system with improved structure that decreases its critical frequency
  • Absorbent at medium and high frequencies
  • The acoustic band improves the loudness of the partition
  • The fifth board ensures the tightness of the system to recessed installations
  • Its thermal and acoustic insulation capacity can be improved by increasing the thickness of the structure and rock wool
  • Light system better for structural strength with low thickness and faster execution
  • Application

  • Public or private residential buildings
  • Public buildings like hotels
  • Teaching buildings: schools, universities, nurseries
  • Sanitary buildings: hospitals, outpatients, health centers, residences
  • Administrative and corporate buildings
  • Auditoriums, theaters, music schools: teaching classrooms

    Unit of Work

    Acoustic insulation of plasterboard separating wall formed by:
    Double plasterboard of 12.5 mm thickness fixed by screw to the structure of 50 mm thick, improved in the union with the structural elements and between profiles and plasterboards, with self-adhesive anti-resonant tapes, FONODAN® 50 and absorbent material in its interior based on rock wool of 70 kg/m³ density, ROCDAN® 231/40; 15 mm thick plasterboard fixed with screw to the 1st structure; separated at least 1 cm from the 15 mm plasterboard, placement of the second improved structure at the junction with the structural elements and between profiles and plasterboards with self-adhesive anti-resonant bands, FONODAN® 50 and absorbent material in its interior based on rock wool of 70 kg/m³ density, ROCDAN® 231/40; fixation of 12.5 mm thick laminated plasterboard to the 2nd structure with screws, fully sealed and installed, ready to apply the finishing.
