The top tape among the joint sealing tapes




Product description

Anyone favouring long-term perfectly sealed construction joints will go for Hannoband®-BG1: Even after a 15-year outdoor weathering test in a joint Hannoband® still clearly exceeds the requirements for protection against driving rain, air-tightness and resistance to weathering according to DIN 18542.


Hannoband®-BG1 XL
Hannoband®-BG1 is also available as Hannoband®-BG1 XL in larger roll lengths especially for window constructions. This helps preventing wastages and facilitates quick assembly.

Hannoband® BG1-M uses Hanno membrane technology for the particularly demanding larger joint widths.
