For those of you who don’t know about it, a sash window is a kind of window comprised 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 have panels opening to the outside, while others have panels that slide horizontally or vertically. 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. 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. The famous Ham House located on the River Thames just outside of London is an early architectural example of a building featuring sash windows. Robert Hooke is credited with creating the sash window, although there isn’t any conclusive evidence that proves this.
Sash windows are frequently installed in Victorian and Georgian homes. 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 design of the sash window, since it can be opened at the bottom and at the top simultaneously. 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.
When you decide to give sash windows a try, be careful not to go with the first window installer you 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.
