摘要

The flap has a leaf (2) held in a flap frame (1) that includes a fastener at its outer sides turned away from the flap leaf for setting frame sections (7, 8) of an insulating frame (6). The frame sections are attached to the fastener. A bracket profile has a longer profile section that is arranged between the frame sections. A shorter profile section of the profile is outwardly present before one frame section (7). A U-profile is arranged in an area of a long side piece of an L-profile. Overall length of the L-profile and/or a Z-profile approximately corresponds to length of the frame section.
