Flexible film used to seal the joints

Overlapping auto adhesive band Impactodan is composed of cross-linked polyethylene foam, 3 mm thick. It is used as auxiliary product when installing Impactodan´s solution for decks. It ensures a correct overlapping between Impactodan rolls, avoiding acoustic shortcircuits that could reduce insulation effectiveness.



  • Thickness: 3mm
  • Width: 70mm | 20mm


  • As it is composed of the same raw material as IMPACTODAN, it provides continuity to the impact noise damping system.
  • It is inert to attack by micro-organisms, ensuring its durability over time.
  • Easy and quick to install.
  • It is presented within a system, collected in Technical Suitability Document No. 439 with on-site tests and a detailed installation that facilitates correct monitoring of the work.
  • Its high resistance to dampness and steam diffusion prevents the fine particles of the mortar from entering the IMPACTODAN joints.
  • Its good thermal conductivity makes it ideal in radiant heating systems, avoiding the creation of thermal bridges in the joints.
  • Its good elasticity under continuous load over time is the manifestation of its usefulness, preserving its acoustic properties over time.
  • Its great flexibility makes it possible to cover installations avoiding the occurrence of unwanted acoustic bridges.


  • It is used to seal the joints between two Impactodan sheets.
  • It can be used for lining installations that have to pass through the floating mortar.
