01Fixed and operable panels do different jobs
A broad central pane preserves the main view, while Chenxing 109 casements at the sides bring in fresh air through integrated screens. This composition avoids filling the outlook with unnecessary mullions while keeping the room naturally ventilated.
02Thermal-break frames reduce a common weak point
Aluminium is strong but naturally conductive. The thermal break in the Chenxing 109 interrupts the direct path between outside and inside, helping the window contribute to year-round comfort when paired with the appropriate insulated glass.
03The largest opening receives the heavier system
The Xining L6 gives the broad outdoor opening a more robust frame and running system. Its final panels, glass and hardware can be configured around span, frequency of use and local wind pressure rather than treating every sliding door as the same.
