Sliding Windows

A replacement [[horizontal sliding window|Horizontal-Sliding-Windows]] is composed of two sashes which are situated next to each other. Some horizontal sliding windows have one stationary sash and one moveable sash while others have two operable sashes. The moveable sash slides to the left or the right on a track or grooves. The operating sash of a horizontal sliding window may be removed or tilted in for cleaning. Horizontal sliding windows are also called "gliding windows," "gliders" or "sliders." They are one of the least expensive operable windows on the market.  

Replacement horizontal sliding windows may be installed in combinations with other windows. Combinations for replacement horizontal sliding windows may include a half-vent horizontal sliding window (one fixed pane and one moveable pane), a half-vent horizontal sliding window above or below a picture window, a horizontal sliding double-vent window (a center picture window and two operable sliding panes on either side) or a horizontal sliding double-vent window installed either above or below a picture window.  

Vertical replacement sliding windows refer to [[single-hung|Single-Hung-Window]] or [[double-hung|Double-Hung-Window]] windows. These windows consist of two sashes which are situated one sash above the other. In a single hung window, the bottom sash moves vertically to allow for ventilation through the bottom of the window. With a double-hung window, both sashes move vertically, allowing the homeowner to increase ventilation through either sash or, when placing both sashes in the middle of the window, through both the top and bottom of the window. Since heat rises this is particularly useful in the summertime when hot air can exit through the top of the window while cooler air enters through the bottom of the window.
