Throwing a curve into designs with bent insulating glass

The BAE Systems building in the Chicago area showcases a unique façade that has curved and parallelogram insulating glass that leaned forward away from the building, creating a rather complicated shape difficult to calculate and draw.

Building professionals now have the flexibility to get creative with building designs and achieve a façade that is beautiful and energy-efficient when correctly installed. The improvement of automated equipment and glass-bending technologies helps minimize hurdles, and the use of flexible warm edge technology for both flat and bent insulating glass continues to expand the possibilities for design professionals. New technologies and streamlined processes make a technically sound building designed for happy and productive occupants achievable. It is a trend bringing an interesting twist into the building and construction industry today.
