Discover a new dimension of elegance and functionality with the sky windows® window system. This virtually frameless sliding window system, made from high-quality aluminum, features an exceptionally slim casement profile of just 21 mm. The large sliding casements, up to 4 meters high, combined with almost invisible frame profiles, offer you an uninterrupted, breathtaking panoramic view. Whether it’s the majestic immensity of the sea, the romantic silence of the starry sky or the immaculate beauty of natural landscapes, our window systems transform every view into a unique visual experience.
In modern architecture, the minimalist choice of materials is essential to create harmonious transitions between interior and exterior spaces. Natural light plays a central role in this process. Our floor-to-ceiling glazed facades perfectly support this philosophy and integrate perfectly into any design concept, from exclusive villas to detached houses and commercial premises. Thanks to over 15 years of innovation and continuous improvement, our invisible floor tracks offer easy, intuitive operation of sliding elements, making our sky windows® system the ideal choice for the most demanding architectural projects.

The sky windows® sliding elements integrate seamlessly into the architecture with customized pocket walls, in which the elements are completely recessed. This design allows the elements, whether operated automatically or manually, to become invisible and visually enlarge the room. It also ensures a stepless transition to the outside, perfectly connecting the interior and exterior ambience.
Our high-quality stainless steel track, seamlessly integrated into the frame, allows for smooth and quiet movement of the sliding elements. This maintenance-free system has a precisely tuned, self-centering roller guide, hidden in the profile, which keeps out dust and dirt. The robust stainless steel rollers ensure easy operation even with elements up to 500 kg. A masterpiece of technology for your comfort.
The system allows for seamless integration into walls, ceilings and floors, ensuring a flush finish. When open, the interior merges seamlessly with the exterior, thanks to the flush-fitted stainless steel rail with no protruding parts. An additional advantage is that the system is maintenance-free.
The minimal windows® freeway running rail, which is installed flush with the floor, ensures a barrier-free passage to the outside and is therefore barrier-free. The outer frame is fully integrated into the floor, so that the running rail is level with the floor and you cannot trip over obstacles. The freeway system is tested, certified and completely maintenance-free.
