The rapidly expanding Cologne-Bonn Airport was enlarged by a new terminal building at the end of the 1990s. The completely glazed façade of the new Terminal 2 building is 800 m long. It is divided into sections 40 to 70 m long and varies in height between 10 and 20 metres. The special feature of this façade is that it consists of thermal glazing panels fixed in point-like mountings. This subjects the load-bearing structure to extreme deformation stresses. All sections of the façade are designed on the same principle i.e. as tensioned cable structures.
