Zusammenfassung: | The combined profile is used in the manufacture of windows and doors for residential, public and industrial buildings. It consists of two supporting semi-profiles (1 and 7), external (1) aluminium and internal (7) wooden, which are interconnected by a screw connection (3) and form a close air chamber (4). The solid internal wooden profile (7) does not allow the formation of condensate. The seals (6, 11 and 12) used, as well as the air chamber (4) improve the heat- and noise-insulation qualities of the products. 3 claims, 5 figures |
