<p>A heat-insulated composite section for doors, windows or facades is comprising a plurality of metal rail sections (3, 4, 5, 6) so connected as to form a frame and at least one insulating rod (7, 11, 27, 46, 47) arranged between the rail sections (3, 4, 5, 6) and having longitudinal edges secured to the rail sections (3, 4, 5, 6) and preferably being made of plastic. Each part (28, 30) of the insulating rod (27) is connected with adjacent rail section (3, 4, 5, 6) in a manner to resist a longitudinal displacement, and central connection between the insulating rod (27) parts (28, 30) if formed by sliding-type guide.</p> |
