Sash window - online puzzles

A sash window or hung sash window is made of one or more movable panels, or "sashes", that form a frame to hold panes of glass, which are often separated from other panes (or " lights ") by glazing bars, also known as muntins in the US (moulded strips of wood ). Although any window with this style of glazing is technically a sash, the term is used almost exclusively to refer to windows where the glazed panels are opened by sliding vertically, or horizontally in a style known as a "Yorkshire light ", sliding sash, or sash and case (so called because the weights are concealed in a box case).
