This type of window is made up of several glass panels that can slide in any direction. The term sash refers to the glazed panel. They can also be called a hung sash. Many people do not know what the origins of the sash window are.
There are different varieties according to the way they slide open. Opening horizontally is called the Yorkshire type. If it opens vertically then it’s just the regular type.
The weight of it needs to be balanced. There can be a heavy iron, lead, or steel weight placed inside the frame. A sash weight can also be applied to balance the weight of the panes. Without this balance, the window will not slide open.
The usual number of panes in each frame is nine. There are three rows of three, or sometimes six panes total which are two rows of three. This can vary greatly depending on the style of the home. A type of rope or chain is used to open it by attaching it to the frame and to the top of the panes.
They are most commonly seen in Victorian houses, and also Georgian. They are said to have been designed by Englishman Robert Hooke. He was a well renowned scientist and inventor. The oldest known installed version dates back to the year 1670.
They are most often made from soft wood materials which are pliable enough to mold around the frame. A single or double glaze may be used on the wood. Standard width is around four feet, but can vary depending on the design of the home.
Knowing the origins of the sash window and how it functions can help one understand it’s advantages and also it’s disadvantages. By efficiently cooling rooms, money can be saved on power bills. The dual openings allow hot air to escape the top, and cool air to enter the bottom. They are very easy to clean as well, and both sides can be washed without leaving the room. The dual sliding panes make it easy to wipe the outside as well as the inside. There are a couple drawbacks however. The natural soft wood is known to rot easily, which often results in rattling panes. Air can seep in as well once the wood is warped. Most builders find them to be hard to maintain, but with a little know how, they can be cared for and look great on any home.
