minimal windows® NGS enables a seamless transition between indoor and outdoor areas through barrier-free openings of entire window façades with heights of up to 6 meters and unlimited length options. Our expertise and continuous development over more than 15 years has enabled us to offer these customized solutions that provide maximum flexibility.
Our minimalist design allows for a harmonious combination of natural light and elegant aesthetics, promoting an inviting atmosphere for contemporary living. Light-flooded rooms with a maximum transparency of up to 99.3% create a unique, airy atmosphere in any home concept.

The side profiles can be seamlessly integrated into walls, floors and ceilings to make them virtually invisible. In addition, we offer motorization for opening and closing the sliding elements, which is capable of moving sash weights of up to 1,500 kg along the stainless steel track.
