Hannoband BG1

For heavy-duty primary and cross joints in façade and window construction
If you need perfectly sealed construction joints long-term, then choose Hannoband-BG1: Even after an outdoor weather test over more than 15 years in the joint, Hannoband still exceeds the requirements for protection against driving rain, air-tightness and weather-resistance in accordance with DIN 18542.

For challenging or large joint widths, we recommend using Hannoband-BG1-M with HANNO membrane technology.
