The outstanding performance of the sliding window is that it can achieve good thermal insulation performance and sound insulation performance, and its various accessories can also make the operation easier to open. Different sliding forms, such as lift sliding doors, also perform well in achieving visibility and a sense of openness. Since the movement trajectory of the sliding window is pushed and pulled in the window frame, it will not occupy the surrounding space, and will not interfere with interior decoration such as curtains and outdoor sunshade shutters, and the surrounding space of doors and windows can be fully utilized.
