For the revitalization of the Sparkasse Duisburg, the building was first built back to the shell until a rear-ventilated plug-in panel façade with a total area of 8,200 m² was subsequently installed and the building's technology was brought up to date. Natural stone and plaster as well as post and beam constructions with cassette awnings complete the modern façade, for which current profile series, thermal and sound insulation glazing and coloured 6 mm thick glass panels were used. Sun protection insulating glazing as well as P4A glazing, outside with burglar resistance, serve comfort and security.
