Slider windows that come with two panes of framed glass are the most popular variety of this type of window. They are attached on rails that are positioned parallel to each other on the window frame. Some types of slider windows have only one of the sashes moving while the other one is firmly attached on the frame. With high end models, slider windows are also designed to be tilted in or out to provide better ventilation.
