What is a sliding window called?

As a Sliding Window supplier, we often hear customers use different names for the same product, including Slider, Glider, and Gliding Window. These windows operate horizontally along a Track, making them easy to use and space-efficient. Common configurations include a Single Slider with one Fixed Pane and one Operable Pane, a Double Slider with two movable sashes, and a Three-Pane Slider featuring a large center glass area with a Sliding Sash on each side.
