摘要

The part (10) has a hollow section (16) comprising a connected main hollow chamber (20) that extends in a longitudinal direction of the hollow section. A reinforcement part (18) is retained in the main hollow chamber. The main hollow chamber comprises a thermal insulation element (22) that is made of thermal insulation material (23) i.e. polymer foam material, where the insulation element is arranged at the reinforcement part and firmly bonded with the reinforcement part. The insulation element extends in a thickness direction of a wall (14) if a frame is installed in an aperture (12). An independent claim is also included for a method for frame for installation into an aperture of a wall.
