Hannoband 3E-BG1

Multifunctional tape for a broad range of applications

With at least two integrated functional membranes, this tape ensures permanently dry connecting joints. MPA BAU HANNOVER has verified that the Hanno high-performance membranes adapt to moisture. Hannoband-3E BG1 is tighter against diffusion on the moister side than on the drier side, thus transporting the moisture out of the joint. The principle works both in the typical winter situation demanded under RAL “tighter inside than out” and in reverse diffusion in summer. The joint is kept dry all year round.
