Installation guidance & recommendations

Surfaces must be clean before application. Recommended installation temperature is above 10°C. Refer to the IMPACTODAN® installation guide and Danosa Constructive Solutions Catalogue for full system instructions. This product may be supplied with or without protective tape.

What is OVERLAP TAPE 70mm used for?

It is used to seal and overlap joints between IMPACTODAN® membranes, ensuring continuity in acoustic insulation and preventing acoustic short-circuits.

Can OVERLAP TAPE be used with underfloor or radiant heating?

Yes. The tape’s thermal conductivity prevents the creation of thermal bridges at membrane joints, making it suitable for radiant heating systems.

What installation conditions are recommended?

Surfaces should be clean and the application temperature should be above 10°C. For best results, installation should follow the Danosa Constructive Solutions Catalogue, Sound Insulation Commissioning, and SPD documentation.
