  • Finishing: As required

Acoustic Insulation


Thermal Insulation


Noise protection Energy saving


  • DnTw airborne insulation between 55 and 64 dB
  • L’nTw impact noise level between 58 and 42 dB
  • Extended Durability
  • High durability of thermal performance
  • Avoid risks of interstitial condensation
  • High vapor diffusion resistance of extruded polystyrene
  • High resistance to compression
  • Compatible with installations on the ground, it is unnecessary to cast a layer of padding
  • Does not need a vapor barrier layer
  • Installation according to DIT No. 439
  • Application

  • Public or private residential buildings on floors that give to non-heated premises or abroad.
  • Graph

    Unit of Work

    Thermal and acoustic insulation on slab in contact with the outside air formed by:
    DANOPREN® TR extruded polystyrene panels, 40 mm thick, with mid-wood perimeter joints, deposited on the slab and protected by acoustic sheet of cross-linked polyethylene and foamed closed cell, 5mm thick, IMPACTODAN® 5, sealed with self-adhesive cross-linked polyethylene tape of 3 mm thick, 70 Overlap tape (Cinta de Solape), mortar at least 5 cm thick separated from the structure and installations by using Peripheral band tape (Desolidarizador Perimetral); ready to install ceramic tiles.
    Installation system according to D.I.T. 439R / 16.
