What is a Window Sash?

Every window that moves has a sash; it is the frame that holds the window’s glass in place, as well as other parts like the mullions or muntins. Some windows may even have more than one sash, depending on how they are designed. Overall, sashes play an essential role in ensuring your windows function properly and look great as they do so.

Each sash is made up of several parts. In older models, sashes can typically be disassembled into their different components. However, newer models are more likely to be completely sealed for better insulation. For example, PVC window frames are welded together, and custom window grilles are often sealed behind the glass.

While all moving windows have sashes, the style of sash varies based on the style of window. For instance, with double-hung windows, you will find one sash positioned above a lower sash. This lower sash is typically the one that moves up and down, although both sashes move in some modern double-hung windows. With casement windows, the sash is “open” to help funnel breezes into your rooms.
