The AT 575 system for window facades with its architectural design was developed as a hybrid between a mullion-transom facade and a window element. The new AT 575 window facade combines the low visible width of a conventional facade with the easy production and assembly of the proven AKOTHERM systems.
Different opening options such as side-hung, tilt, and tilt and turn, etc. can be implemented with standard hardware technology. Both surface-mounted as well as concealed hinges can be used.
