Hanno Sealing and Insulation

Gaska Tape Sales stock the Hanno range of expandable sealing and flashing tapes.


These products are manufactured in Germany under stringent quality systems and perform to internationally recognized standards. They perform a vital role in improving the thermal efficiency, water tightness and habitability of buildings through the creation of effective seals around penetrations in a building’s envelope. Their extensive range has applications for sound proofing as well. We stock and recommend the following products from the Hanno range.
