Sash Window

Sash windows are made up of two movable panels which are known as ‘sashes’. The sash itself is composed of panels of glass, individually called lights. With modern technologies, however, it becomes only one pane of glass rather than smaller panels.
Most commonly, the panels move vertically, but you can get horizontally opening sash windows, too. Vertically opening sash windows are assisted by balancing weights, pulleys and springs, which are hidden within the window frame, which helps in opening the window.
The sash windows are classified in following way:

There are six panels of glass on the upper sash, and six panels of glass on the lower sash known as “six over six sash window”.
