17m tall glass façade for messeturm frankfurt

The Messeturm in Frankfurt am Main, opened in 1991, is the second tallest building in Germany. Due to its special shape, the postmodern building, designed by architect Helmut Jahn, is also called "pencil" by the inhabitants of Frankfurt.

The lobby of the Messeturm on the ground floor is to be modernized according to the design by Helmut Jahn and Matteo Thun & Partners. The design features a 17m tall glass façade on each of the four sides of the tower, projecting out from the existing façade and thus expanding the area of ​​the lobby. It consists of approx. 17 x 2.8m cold bent insulating glass units, which are held by 5t stainless steel columns. The façade is topped by an approx. 250sqm steel-glass roof. Its beams are screwed to the vertical steel columns of the façade at the joint.

  • The scope of work also includes integrated revolving doors with an all-glass design as well as double-leaf glass doors. These are surrounded by stainless steel portal frames, in order to decouple them from possible deflections and movements of the extremely high façade.

    Furthermore, an interior, point-fixed steel-glass façade will be build, a so-called Light Wall, consisting of 3.1 x 1.8m large, hot-bent glass elements with a translucent interlayer. An operable LED technology will provide backlighting for the elements and highlight the lobby.
    The installation of the exterior façade is planned to start in August 2019.

Never before have such large glass elements been installed in a skyscraper. This challenge demands maximum precision from logistics and assembly.
