How Do Sash Windows Work

Sash Window Operation Instructions

 Sash windows are vertically opening windows that consist of two framed window sashes, one positioned in front of the other. This style of window unit sits in frames with vertical grooves, which allow them to move up and down smoothly. The up and down movement is assisted by counterbalances which are weights on cords and pulleys. 

When closed, the top and bottom sash will be locked together at the midrail to prevent them sliding. There may be handles attached to the sashes to help you open them, depending on the window design.

The window can be opened by sliding the bottom sash upwards or, if you have a double hung window, by sliding the top sash downwards.

Sash windows can be fitted with complex hinge systems that allow the window to be locked on one side while the counterbalance on the other side can be detached. This is a helpful feature that can allow the window to be opened to let fresh air into your home, to get out, or to clean.

The design of sash windows also have benefits such as: 

  • They look good: they follow a smart aesthetic and increase the value of the building. 
  • Sash windows are safe & secure: only one panel can open at a time meaning that they are a lot more difficult to break into than cement windows. It is also easy to have additional features added for safety precautions such as locks and child safety devices.
  • Low maintenance: modern sash windows have a very low risk of warping and rotting as they are made of metal and plastic. You don’t need to sand them or apply coats of varnish either. More traditional sash windows are made from wood, but with appropriate care and maintenance they will have a long life.
  • Environmentally friendly: timber-framed windows are environmentally friendly as it uses the lowest amount of energy in its processing, production and transport. It also has a very long life-span meaning it won’t have to be replaced as regularly as other windows.
