The three glass facades all boast large-scale glass formats, some of which border on the technically feasible. The panes of the room-enclosing structural glazed facade are 6,235 millimetres long and 3,208 millimetres high - with a glass band dimension of 3,210 millimetres! The VISS Semi SG steel system from Jansen was chosen for the full-glass faade, reinforced by the metal fabricator – Radeburger Fensterbau – with a substructure specially developed for this purpose and mounted at short intervals.
