minimal windows® NGS

Next generation minimalistic sliding system

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 advanced minimal windows® NGS system offers versatile design options, such as customizable glass thicknesses from 34 mm to 74 mm. 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.

The possibilities offered by NGS provide limitless possibilities in the planning process and we are ready to turn your individual visions and requirements into reality.

Flush Installation



Flush Installation

The outer frame blends seamlessly into walls, ceilings and floors and provides a flush finish. This design enables a smooth transition between indoor and outdoor areas without steps. Our frame profile, which is installed flush with the floor, guarantees an elegant appearance.

Threshold-Free Transition NGS



Threshold-Free Transition NGS

The flush-mounted minimal windows® freeway track provides a threshold-free passage to the outside, making it fully accessible. The outer frame is fully integrated into the floor, so the track is level with the floor, eliminating any obstacles to trip over. The freeway system is tested, certified, and maintenance-free.

Security

Our self-centering integrated stainless steel rollers are built into the bottom profile of the sliding elements, protected from dust and dirt, to ensure long-lasting performance.
