If you aren’t familiar with what sash windows are, they are a kind of window made up of movable sashes or panels. The way you can tell whether a window is a sash window is if it has a frame holding together several panes of glass. Quite often narrow muntins separate the panes.

A few kinds of sash windows exist. Some of these have horizontally or vertically sliding panels, while others are simply opened toward the outside. The sliding sash windows sometimes are referred to as sliding sash, case, sash or Yorkshire light windows.

American-style traditional sash windows are another kind of sash window; they have two sashes with one placed over the other one inside a frame. Each of these separate sashes can slide up or down within the window frame. This kind of window has the advantage of you being able to remove or tilt the sashes whenever they need to be cleaned. There are many different configurations, models and shapes to choose from within this class of sash window.

Sash windows were first put up in England in the late 17th century. Ham House is a famous early house that had sash windows. Robert Hooke is credited with creating the sash window, although there isn’t any conclusive evidence that proves this.


To get in touch


Sash windows are frequently installed in Victorian and Georgian homes. The six-over-six panel window is the classic sash window and comprises two panes up and three across. The standard size of sash windows is four feet wide; however, wooden sash can fit almost any size and there is no fixed rule.

In order for sash windows to function, there is panel that is balanced through using a counter-weight made of heavy steel or another material hidden within the window frame.

Usually sash windows are made out of single glazed glass and soft wood, although sometimes double glazed glass is used.

Due to the fact that sash windows need to be able to slide to close and open, they are prone to more problems than other kinds of windows. They require a lot of maintenance as well; however, the extra work involved is worth it since sash windows are very attractive.

Besides being aesthetically pleasing, sash windows are more practical too. They work better in keeping the temperature inside cool during warmer months. The reason for this is that sash windows open at the bottom and top. The room’s warm air is allowed to escape through the top opening, while cool air coming from outdoors is allowed in through the bottom opening.

A new kind of sash window was released recently into the marketplace. They are called uPVC sash windows, and they are attractive like regular sash windows are but are much more energy efficient and don’t require as much as maintenance and painting on a regular basis.

Like anything else, don’t choose the first windows company that you happen to find. Make sure to get work samples and quotes from thee different companies at least before you make your final decision on which company you want to have install your new windows.
