Noise protection

IMPACTODAN

Noise protection

Advantages

  • Airborne noise insulation towards the lower floor DnTw > 60 dB
  • Impact noise level towards the upper floor L’nTw < 35 dB
  • The ideal system for damping impact noise at low frequencies
  • The cross-linked polyethylene sheet protects from moisture and improves the damping behavior of the system
  • The mortar armed with mesh allows the entire interior partition to be built on the floating floor, reducing acoustic bridges
  • Application

  • Premises with night time: restaurants, breweries, bars
  • Supermarkets
  • Bakeries
  • Mechanical workshop
  • Music schools: music booths
  • Clubs in shopping centers
  • Graph

    Unit of Work

    Acoustic insulation at low frequencies on floor formed by:
    Rock wool panel with a density of 100 kg/m³ and a thick¬ness of 30 mm, ROCDAN® 233/30, placed on top of the slab and protected by chemically cross-linked and foamed polyethylene sheet, 10 mm thick, IMPACTODAN® 10 fixed to each other with self-adhesive cross-linked polyethylene tape of 3 mm thick, Overlap Tape 70 (Cinta de solape), mesh reinforced mortar with at least 6 cm thick, separated from the structure and installations by using Peripheral band tape 200 (Desolidarizador perimetral), ready to install the finishing.
