A window is referred to as a sash window if it has one or more movable panels, which are called sashes. If the window is made up of several individual lights or pieces of glass held together by a frame, then it is a sash window. Quite often narrow muntins separate the panes.
There are several different kinds of sash window. 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.
The typical American style sash window has a frame with a sash on top and one below. This type of window is opened and closed by sliding up and down. One of the benefits of this window is the ability to remove or tilt the sashes in order to clean them. There are many different configurations, models and shapes to choose from within this class of sash window.
The sash window has a long history, originating in England in the mid-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.
Sash windows are frequently installed in Victorian and Georgian homes. These houses usually feature a classic six-panel sash window with two sashes, each featuring three panels above and below. This is often referred to as a six-over-six panel 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.
A sash window is more likely to need some routine maintenance than a fixed window due to the fact that the panels slide each time the window is opened and closed. 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 being very attractive, there is another significant advantage that sash windows offer compared to regular windows- they’re more efficient when it comes to cooling a home’s interior when the weather is warm. 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.
