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 up to 6 x 1.8m large, hot-bent glass elements with translucent interlayers. LED panels installed at the rear of the façade will provide passive lighting and set the stage for the lobby.
    Installation of the exterior façade is scheduled to begin in August 2019 and the interior façade in September 2019.

Installation progress

The Messeturm in Frankfurt am Main, opened in 1991, is the second tallest building in Germany. 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. Never before have such large glass elements been installed in a skyscraper. This challenge demands maximum precision from logistics and assembly.

The safe transport of the oversized glass units is carried out by means of specially adapted internal loading racks. Special tarpaulins for weather and transport protection were also produced for the project.
