Venetian Sash Windows were a standard design 100 years ago for terraced houses all over England. The weights which balance the central sash are situated in the two outer boxes to allow a smooth gliding movement whilst the central mullions retain a slimmer look.

The triple design and slimmer mullions of Venetian windows were commonly found in terraced houses in the late 1800s, but are less common in more recent years. So what is it that makes these Venetian sash windows different from the more typical sliding sash window?

As mentioned already Venetian sash windows are divided into three and usually only the central window sashes are moveable, with the outer sashes bering fixed (although it is possible to alter this configuration so that all sashes can slide up and down).

The slimmer mullions, which give the unique look to Venetian sash windows, are created because the cords for the central sashes go through the top of the mullions, over the pulleys and then into the side boxings. The weights that balance the window are located in the outer boxes.
