Commercial building windows need to possess several characteristics: They let in natural light, provide large views, and add to the exterior appeal of the building. At the same time, windows for commercial buildings also need to have the function of high-performance energy efficiency.

Therefore at that time, our design idea was to provide a larger light area while maintaining the overall aesthetics and maintaining good ventilation.

With the intention of maximizing as much natural light as possible, sliding doors are usually large glass panes that extend from the ground to the ceiling, enabling you to enjoy both indoors and outdoors in all weathers.
