Design with Overlength Glass

from 6 to 18 metres

Design and use

Overlength glass shapes the architectural character of a building's exterior as well as altering the internal atmosphere. Inside, the boundaries seem to increasingly disappear and daylight floods the space. Outside, the large glass facades appear seamless and monumental.

Overlength glass panes are recommended wherever the goal is to achieve an open, airy design with fluidity between the interior and exterior environment. The spectrum of applications in construction where Overlength glass panes can be used is broad:

UN Building, Geneva

Overlength has a history in architecture. The UN building in Geneva was built with 13-metre-high glazing in 1971.

Design options

The usual float glass types (Diamant and Planiclear) and to-be-tempered coatings (COOL-LITE XTREME, COOL-LITE SKN and Planitherm) can be used in Overlength formats. In addition, the glass can be processed, assembled and refined using all the processes known from standard formats.
