The GEALAN-KUBUS® system presents a revolutionary form concept for uPVC windows in architecture. More light and open space thanks to larger glass surfaces open up new freedom of action. Thanks to the fully concealed sash, the distinction between the interior of the room and the view from the window is blurred. The overall harmonious impression of integrity and clarity of form is created by the single plane between frame and sash. Whether for new construction or renovation, GEALAN-KUBUS impresses with its versatility as a complete system platform comprising windows and sliding doors.
