Minimal Keller Highline

Facades with continuous fixed glazing

The minimal windows® highline systems by Keller combine ultra-thin aluminum profiles with fixed glazing to create large and aesthetically appealing fully glazed facades. Thanks to the huge glass fronts with an area of up to 18 m², you can enjoy an unrestricted view.

Frameless glass facades further emphasize the unmistakably minimalist style of contemporary residential and commercial buildings. The flush glass fronts can either be executed as fixed glazing or seamlessly combined with our double or triple glazed minimal windows® sliding elements.

For the necessary stability, the minimal windows® highline systems offer three different construction options: frameless all-glass appearance, single-sided structural glazing, and Cover-Cap-Look.
