Exclusive Home Design
The minimal windows® curve range consist of rounded glass elements, making it possible to create innovative structural contours and curved outlines. The unusual custom-made silhouettes open up a whole new world of possibilities for architectural design. The minimal windows® curve range lends a fascinating, flowing, sometimes futuristic, feel to avant-garde structures. Each configuration expresses exceptional craftsmanship. Keller minimal windows® harnesses the technical expertise and talent of its team to create elements that allow architects and designers a free reign, letting their imaginations take flight. The minimal windows® curve elements are specially made for each project, so every single creation is truly unique.
Countless aesthetic constructions, crafted from combinations of straight and curved minimal windows® elements, are possible. The fixed and sliding window options offer flexible design choices, providing creative design freedom and the same superior functionality. The curved glass units are fashioned in kiln baths, so that they are a perfect fit for our custom-made aluminum frame constructions.
The flowing contours and subtle transitions allow maximum natural light to infuse any living environment. Generous dimensions, of up to 4.5 m in height, allow the installation of curved elements with a minimum radius of 4 meters. The curved, glazed sections can be opened and closed with ease.

The combination of large straight and curved minimal windows®, both fixed and sliding windows, unlocks countless possibilities for architects and planners when they’re designing your dream home.

The rounded glass elements can be integrated into single, double and triple Keller minimal windows® systems. These can be combined with any of the other system elements, to create a continuous glass facade. Innumerable configuration options will satisfy even the most imaginative designer.

The curved outer frames can be entirely recessed into walls, ceilings and floors. The bottom of the outer frame, with integrated stainless-steel sliding rails, is flush with the floor.

Every minimal windows® curved system is subjected to individual wind load and waterproofing tests. Our drainage system is adapted to the shape of the curved installation, guaranteeing exceptional water run-off and drainage.


Architects, planners and homeowners adore the abundance of design options available when employing our premium minimalist systems. Our engineers are exceptionally detail-oriented, paying attention to every single design element. We strive for perfection.
