During the summer, many of the ufaFabrik’s events, like the Sunset Varieté, are open air events. These events can be very loud, and to avoid disturbing the residents living across the Teltowcanal a “verticope” was developed. This name derives from the words “vertical” and “biotope” and describes the 50 meter long and 5 meter high greened soundproof wall, which also provides a habitat for insects and birds. The wall consists of a steel structure with dense fiber matting on the outside, on which grasses and herbs grow. The hollow space inside is filled with sand, stones and soil to provide the wall with enough mass to absorb most of the sounds. It can also store rainwater, which helps the plants through dryer periods.
