Before you do anything, be sure to read our guide below to learn about Wooden Sash Windows

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.

There are several different kinds of sash window. Some sash windows have panels that open to the outside; others have panels that slide to open – either horizontally or vertically. The sliding sash windows sometimes are referred to as sliding sash, case, sash or Yorkshire light windows.

The American-style sash window is a traditional variation that has two sashes, one of which rests on top of the other within a frame. This type of window is opened and closed by sliding up and down. One major benefit of this window is that the sashes can be tilted or removed for easy cleaning. 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 example of a property with 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


Victorian- and Georgian-style homes often have sash windows. The classic type of sash windows has three panes placed horizontally and two placed vertically, resulting in a six-over-six paneled window. 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. This is due to the fact that sash windows open at both their bottom and their 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.
