Windows are more complex than expected. They come in countless shapes and sizes, from very small and intricate, to large and majestic, and may be manufactured of many different materials, yet most are made of the same components. Terms for these components can be confusing, but knowing the right names for parts of a window can help select the window to meet the building’s needs. The two main pieces of a window are the frame and the sash.
A window frame is the framework that surrounds and supports the entire window system. Frame sizes vary and range from standard dimensions to custom-designed. The head, jamb, and sill make up the window frame.
The sash is the area inside the frame, the part that holds the glass. The sash may or may not move. For a single-hung window, the lower sash is the piece that slides to open the window. The sash has several components.
Knowing window terminology helps with identifying the building's needs and selecting windows to best meet its requirements.
