What Is a Slide Up and Down Window?

A slide up and down window, also known as a sash window or vertical sliding window, is a window system where the panel moves vertically instead of sliding sideways. The panel can be lifted upwards or lowered downwards, depending on the opening style.

Slide up window can be designed without a bottom frame for a cleaner look, making it easier to pass items across. The sash window can also stop at any position, allowing flexible control of ventilation.
