Edgetech Super Spacer used in KÖ-Bogen project, Düsseldorf, Germany

Written by Chris Alderson

The KÖ-Bogen building complex is located in downtown Düsseldorf close to the Hofgarten – the city’s central park. It is a visually impressive structure with a large, curved glass façade and unusually shaped architectural design. For the development project, Edgetech supplied Super Spacer for use in the glass structure measuring over 2,200m².

Stylish multi-use complex in one of Germany’s largest cities

The KÖ-Bogen building enjoys an enviable location in the heart of Dusseldorf city centre. It has been designed to tastefully complement its urban setting with its bold architectural style, while also referencing the close location of the Rhine river and the natural environment with its use of non-standard curtain walling.

The six-storey building complex functions as a multi-use arena for over 40,000m² of office and retail space. Two buildings have been joined under one continuous roof, connecting the pedestrianised streets nearby with the Hofgarten park. The east and west blocks are connected via a terraced roof bridge while the green space below is illuminated by the optimized use of natural light.

Collaborative working for a spectacular building

When working on such a large scale and architecturally impressive project, collaboration was essential. Working alongside Building Client Glasbiegerei Döring and with world renowned architect New York based Daniel Libeskind, Edgetech were tasked with supplying Super Spacer for all the 2,200m² of glass.

Each individual element of the glass façade measured either 1.35m x 2.70m or 2.70m x 5.60m to meet the architectural design. With the building standing at 26 metres in height and with a 500m circumference, it was essential that all parties were aligned when specifying the glazing. Fortunately, Edgetech’s years of experience in high-profile glazing projects were instrumental in bringing the project to a successful conclusion.

Carsten Kunert of Glasbiegerei Döring commented on the project: “The requirement for excellent energy efficiency and the desire for curved glass façades in architecture is increasing and this project is a stunning example of how well those two things can be executed side by side, with no compromise necessary. Super Spacer® is easy to apply and offers excellent performance in the field.”
