Hanno Flashing Tape DUO

Moisture-adaptive tape for indoors and outdoors

Hanno Flashing Tape DUO consists of an air-tight modified polaymide film with a reinforced nonwoven material-film combination. The tape consists of five flat layers. Thanks to its variable sd-value, it is suitable for indoor and outdoor use, and creates a dry joint under any weather conditions.

The film adapts to the temperature conditions, ensuring moisture in the joint can escape to the outside when the outdoor temperature is colder, allowing it to pass inside when indoor temperatures are warmer.

The self-adhesive attachment strips enable simple, full-coverage installation of the flashing tape for plastering or painting over.

The tape can also be equipped with two self-adhesive strips or butyl strips for
a wall connection.
