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 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 traditional sash windows found most commonly in the US and UK are made of two sashes that are positioned in a frame with one over the other. Each of these separate sashes can slide up or down within the window frame. This makes these sash windows easy to clean because the individual sashes can tilt in or come out altogether. There are many different configurations, models and shapes to choose from within this class of sash window.
The origin of the sash window dates back to the 1670s when they were first installed in England. 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.
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 a sliding motion is required in order to open and close sash windows, they can be more vulnerable to problems than other windows. They require a lot of maintenance as well; however, the extra work involved is worth it since sash windows are very attractive.
In addition to the aesthetic appeal of sash windows, they are also more efficient in cooling the inside of a building during warm weather than other kinds of windows. 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.
