What Is a Window Sash?
A window sash is the part of a window that holds the glass panes in place. It typically refers to the movable framework — or casing — that can be raised, lowered, or slid horizontally, depending on the window’s design. Traditional double-hung windows usually feature two sashes that can both slide up or down. Essentially, the sash of a window allows it to open and close while securing the glass in the window frame.
