Keller minimal windows® has spent 15 years perfecting the development and manufacture of minimalist window and door systems.
We strive to combine optimal minimalistic design with maximum functionality. The concept of “less is more” has shaped contemporary residential architectural trends and been a significant inspiration for the development and design of our systems. Our aim is to offer system options that complement the spirit and design of your luxury living spaces.
Durability and smooth functionality are central characteristics which distinguish our system components and options. We developed a self-centering, integrated roller carriage to ensure superior sliding performance and silent operation. The roller carriage is concealed in the lower profile of the sliding leaf. Top-quality stainless-steel rollers ensure high load stability and smooth rolling performance, which is why our minimal windows® system is one of the best maintenance-free systems on the market.
