Abstract: In the window unit composed of a window pane and frame, the frame has two profiled sections. The first profiled section serves for connecting to the window pane and generally extends along the entire window pane edge and bears against it at an edge region or at two or three edge regions. The second profiled section serves for connecting to a decorative strip and therefore generally extends over only a predefined longitudinal section of the frame. The second profiled section of the frame generally has a plurality of longitudinal sections with a bearing face for the decorative strip. In addition, the second profiled section generally has a plurality of longitudinal sections each with a continuous cutout, located in the region of the horizontal projection of the decorative strip, for a securing strip. On the underside of the decorative strip there is a longitudinally extending cutout with a cross-sectional constriction.
