Keller minimal windows®

Keller minimal windows® is a leading system manufacturer for aluminium design sliding systems. The innovative, virtually frameless sliding windows and doors are installed in particular in higher-class private and commercial buildings.

Individuality is our strength, every project is unique. Development of the Keller minimal windows® design sliding systems began in 2007. Minimum facing widths of the profiles, post-free corner solutions and the possibility of large glass areas of the sliding systems cater to the architectural demand toward transparency and the creation of light-flooded rooms.
