Wind-resistance and vibration absorbing: the straight materials on the inner frame are of hollow design and have good wind-resistance and vibration absorbing properties
Inner and outer frame is flexibly jointed and triple seals are used (one glue strip and two wool strips)
This renders the windows with excellent air and water-tightness and ensures they can be freely and silently slid
Oblique stepped structure and the drain in the downward slide ensure free water discharge without any back-flow
Hollow glass structure in the windows renders excellent sound and thermal-insulation, meeting state requirements on environmental protection and energy saving
Window is provided with thief-proof, airflow barring, loose-proof units and unique multi-point locks, thus keeps stable, tight and safe
