PURPOSE: A high-airtightness insulation center bar for a window with a differentiated face is provided to facilitate the assembly of an insulation center bar by minimizing torsion and to improve airtightness and heat insulation properties through excellent engagement. CONSTITUTION: A high-airtightness insulation center bar for a window with a differentiated face comprises an outside lateral body (100), an inside lateral body (200), an intermediate body (300), and a connector (400). The intermediate body is installed between the outside and inside lateral bodies. The connector is installed between the outside lateral body and the intermediate body and between the inside lateral body and the intermediate body. The intermediate body comprises a rail, an upper connector (410), and a lower connector (420). The rail is protruding to the upper side and allows an upper window (20) to slide. The upper connector connects the outside or inside lateral body to the intermediate body. The lower connector is separated from the upper connector. The lower connector is vertically symmetric to the upper connector. |
