Heat damming device for thermal insulation of hollow chamber section for window or door, has predetermined breaking points that are arranged between thermal insulation elements

摘要

The device (101) has first thermal insulation element (102) and a second thermal insulation element (104). The predetermined breaking points (106,200,202) are arranged between the thermal insulation elements. The predetermined breaking points are provided with perforation and recess. The material cross section of the heat damming device in the region of the predetermined breaking point is reduced by more than half. Independent claims are included for the following: (1) a hollow chamber section arrangement; and (2) method for manufacturing hollow chamber section arrangement.
