Wehrhahn Line, Düsseldorf

Fire protection, laminated safety glass

  • Wehrhahn Line turns glass into art

    The six new underground stations of Düsseldorf’s Wehrhahn Line are the latest artistic and architectural flagship projects of the metropolis on the Rhine. To implement the project, the glass specialists from Glas Wagener used some artistically designed wall cladding in glass as well as skylights that also serve as seats and signs with LED back-lighting. As well as these sophisticated technical solutions, the logistics for the project were one of the other challenges to be mastered by Glas Wagener.

  • Functionality meets aesthetics

    The Schadowstrasse station, where Glas Wagener installed around 2,000 m2 of glass surfaces consisting of laminated safety glass made from panes of toughened safety glass, played a key role in the project. The printing of the glass was part of the overall artistic concept. Apart from functionality, therefore, great importance was attached to the aesthetic impact of the glass surfaces. To realise the project Glas Wagener worked very closely with the architects and with the executing artist Ursula Damm.

    In the process, the colour scheme for the glass surfaces, some of which were monochrome and some printed with an interpretation of the city of Düsseldorf, was optimised in several stages. The coating for the monochrome surfaces was done using a rolling method. In the case of glazing with special films, digital printing was used. The wall cladding was installed as a ventilated curtain facade on a stainless steel supporting structure that was also fabricated by Glas Wagener. The stainless steel protects from corrosion and also serves as a fire protection element. Point fixings integrated into the glass mean that the fixing of the cladding is not visible.

    Glas Wagener was also involved in fitting the five other stations on the Wehrhahn Line. This means that the glass producer from the Arnold Glas Group installed about 300 square meters of plate glass at the Heinrich-Heine-Allee station, which are also part of the artistic concept for the Wehrhahn Line. As at Schadowstrasse station, laminated safety glass was used here as well.

    Elaborate skylights with seating function

    For the designers of the station, the connection between the underground stations and overground urban space was especially important. This connection was realised at Heinrich-Heine-Allee and Schadowstrasse stations e.g. by integrating skylights. What is special about the skylights is that they do not just serve to let light into the stations. They can be walked on at street level and offer passers-by the opportunity to spend some time on a very sophisticated seat in timber and stainless steel and watch the world going by in the underground station below.

    For this special project, Glas Wagener used laminated safety glass with a fivefold coating, the top pane of which has a protective film. In the event of damage e.g. due to vandalism, the skylight can therefore be restored cheaply. For fire protection reasons the bottom pane consists of a class F30 borosilicate glass from Schott. Incidentally, fire protection glass from Promat, a partner of Arnold Glas, is also used for other areas of the Wehrhahn Line. This glass too ensures that the stations make a bright, friendly and open impression. Open visibility also makes for easy navigation within the the stations.
