The sash is the frame that holds the glazing. In a sash window, there are 2 sashes which slide vertically (normally) or horizontally (oacssionally) in a box frame. The frame is receessed into the walls.
Double-hung sash windows have both sashes operational. These are in contrast to single hung sash windows which incorporate one fixed sash and one moving.
To enable the sliding, there is a system of pulley, cord and weights or a spring mechanism.
Although sash windows can be made of various materials., tImber is historically the main construction material.
There are different types of sash window:
Yorkshire sash – this slides horizontally instead of vertically. As such, it does not require the pulley or spring mechanism.
Wyatt window or tripartite – this has a timber mullion separating a normal portion sash with two narrow sidelights.
Bay window – a bay window is generally 3 flat windows with a central picture window and 2 side windows.
Bow window – a bow window is a series of 5 or 7 windows where both the glazing and timber are curved.
