BAU 2023: Next Generation Sliding system design and more to explore at our booth in April 2023 in Munich

Keller minimal windows®, a leading global designer and manufacturer of innovative, virtually frameless, aluminum window and door systems, will showcase the latest solutions and innovations at BAU trade show in Munich, from April 17 to 22.


BAU is the world’s leading trade fair for architecture and construction. It features materials, technology and systems for commercial and residential construction and interior work for both new-build and modernization and renovation on more than 200,000 square meters of exhibition space. It covers the complete range of state-of-the-art technology in the international building industry and concentrates on topics that are shaping and moving the industry.

Next Generation Sliding system - pacing technologies in the pipeline

Ever since we developed our first high-end and virtually frameless aluminum minimal windows® system in 2007, Keller minimal windows® has never ceased to innovate and continues to develop solutions that respond to ever-changing market trends and demands.

The revolutionary and complete redesign of the framework of the Next Generation Sliding minimal windows® system, unifying application for various glazing parameters - is in the focus of the KELLER Development Centre this year.

All parts, from connections to seals, from profiles to sliding parts are to be practically reinvented. We are braced for presenting these innovations and design to a wide audience during BAU 2023 in April 2023 in Munich and to intensify the discussion on trends and market demands to include this into the new development.

Keller minimal windows® NGS is a unified design of the Next Generation minimalistic sliding systems, optimized for different thicknesses of glass and applicable to various types of glazing and the combination of its elements.
