What is a sliding sash window?

Sash windows are the type of window that does not have a hinge to help them open. A traditional timber sash window will usually be made up of two sashes, these either slide up and down (vertical sliding sash windows), or side to side (horizontal sliding sash windows), one behind the other, depending on the type of sash window that you have. Traditionally they also have a rather deep bottom rail which adds to their character.

How do UPVC sliding sash windows work?

These windows work by moving in vertical grooves in the window frame and are counterbalanced by a load mechanism comprising weights on cords. Sliding sash windows refers to the type of windows that can be opened both top or bottom, or both and from either side. Commonly these types of windows do not have any outward swing, however more modern window designs offer a tilt function which makes them much easier when it comes to cleaning the outside.

The glazed area of the timber sashes are made up of smaller panes of glass divided by glazing bars. The era of the property will usually determine the number of panes that are present in your window.

UPVC windows generate a lot of waste and are not particularly environmentally friendly, which is one of the reasons we choose to specialise in timber products.

How sliding sash windows work

As a window style, the humble sash window has been around for many years and works very well to allow either a little air into a room or more, depending on the weather outside. In terms of energy efficiency this is great news because it puts you completely in control.

Inside the frame of each window is a weight and cord system that allows the window to be pushed up or down, to open or close, these weights, or as they are sometimes referred to balances, can be completely concealed within chambers in the frame so that they are not seen, or can be created in a selection of colours to match your frames if you would prefer them to be visible. This sophisticated mechanism allows the window to stay open until you want to close it.
