A window is referred to as a sash window if it has one or more movable panels, which are called sashes. 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.
Sash windows come in many different varieties. 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 sash window operates with an up-and-down sliding motion. 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.
The sash window has a long history, originating in England in the mid-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.
Victorian and Georgian style homes usually feature sash windows. 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.
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 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 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.
