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.
