The exceptional design quality of the Weltnorm NO-FRAME window has also been recognised internationally.
The window has received the prestigious German Design Award 2026, confirming its outstanding design, innovation and refined functionality.
Without visible frames, the NO-FRAME system represents more than just a contemporary aesthetic. It gives architects and designers complete freedom in shaping façades and interior spaces, without visual interruptions.
The exterior creates a uniform, clean surface that emphasises the architectural lines of the building, while the interior side adapts seamlessly to the design of the space.
The NO-FRAME window retains all the functionality of a conventional window while allowing full inward opening along the vertical axis. This ensures easy access, natural ventilation and a greater sense of spatial openness. All functionality is seamlessly integrated into the minimalist design.
Despite its fully concealed appearance, the NO-FRAME window retains all the functionality of modern windows.
Tilt opening along the horizontal axis allows efficient and secure ventilation without affecting the minimalist appearance of the window.
On the interior side, the NO-FRAME window can be finished with a wall or decorative panel that visually connects with the interior design of the space. The panel allows aesthetic coordination with materials, colours or patterns, while emphasising architectural clarity without visible frames.
For a completely minimalist appearance, the NO-FRAME window can be fully finished with plaster. The frame and all technical elements remain hidden within the wall, leaving only the glass surface visible.
The result is the effect of an invisible window, where the glass blends seamlessly into the wall, creating a perfectly clean and uninterrupted architectural line.
