• Nietturm Zürich: We open the window to our innovations

    The rivet tower which is part of the historic "Schiffbau" in the Zurich Escher-Wyss area is being renovated. The Krapf AG installs 20 individually manufactured air-lux descending windows and 170 pieces of electrochromic glass that tints automatically. On the one hand, this massively improves the room climate and on the other hand, it reduces energy consumption.
