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 narrow muntins. 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).
A significant advantage of sash windows is that they provide efficient cooling of interiors during warm weather. Opening both the top and bottom of a sash window by equal amounts allows warm air at the top of the room to escape, thus drawing relatively cool air from outside into the room through the bottom opening.
Traditional sash windows is one of our most requested products. We produce sash windows according to our client’s individual requirements using sustainably sourced European Redwood pine or oak.
