Vizus AT135 is composite window system with inward opening, characterized by extremely pronounced resistant properties. As a response to the rigorous requirements of the principles of sustainable architecture, the performances of the window were enhanced to the maximum: thermal resistance, wind resistance, air, water and sound proofing. The realized thermal conductivity coefficient of the window sash, combined with the technological improvement in the production of glasses ranks AT135 among the latest generation of top performance thermally resistant window systems.
The resistant properties of the system are emphasized by the massive dimensions: basic frame thickness 116mm, sash thickness 135mm and total sash height 130mm. The hardware slots are set in the aluminum, thermally resistant profiles, and they are made as a Euro slot system.
The design of wide, even surfaces and sharp lines suggests the monolithic quality of clearly defined frames. The window AT135 with its massiveness, contemporary and straight lines, undoubtedly belongs to the passive house esthetics. Excellent structural properties facilitate construction of the large window schemes, whereby massive wooden frames give a special impression of warmth in the interior.
