Abstract

A heat-insulated composite section for doors, windows and facades, includes a plurality of metal rail sections so connected as to form a frame, at least one insulating rod arranged between the rail sections and having longitudinal edges secured to the metal sections, and a compensation structure provided in a longitudinal connection zone between interconnected components for eliminating a flexure of the rail sections when subject to uneven temperature rise. The compensation structure effects a slight resistance to longitudinal displacement, or resistance to longitudinal displacement that approaches zero, or is formed by a sliding-type guidance.
