Appreciating The Style And Functionality Of Sash Windows

The old-fashioned appeal of sash windows is one that is appreciated by many. Prior to the invention of the sash window, casement windows were widely in use. There was a status associated with having the new style of window, as it was quite an innovation at the time. The popularity of the sash has come and gone over time, but today many more people appreciate them for their attractiveness and benefits.

There is some disagreement regarding where this style of window was invented, but it is considered essentially British and may have been invented in the UK. The earliest examples known today date from the latter half of the seventeenth century. Georgian, Victorian and Edwardian houses generally were made with the sash style of window. The sash is the traditional window style in the United States and other countries colonized or influenced by Great Britain.

Typically this window takes the form of two sashes, which are also known as panels or frames. Several glass panes usually comprise each sash, separated by narrow bars, with a typical arrangement of three panes wide by two panes high. While most sashes move vertically, some of them do slide from side to side. A window where both sashes move is referred to as double hung, while a single hung style has the upper sash secured in place and unmovable.

While wood, particularly oak, was the first material used for this type of window and is the traditional material used, other materials are used today. In contemporary construction windows of PVC, vinyl, aluminum and other substances may be made. Most of the windows have been single glazed, meaning one layer of glass, but double glazed windows are also made. They are better at keeping the house an even temperature because they reduce transfer of heat or cold from outside air.

There are several advantages to this style of window. On a double hung window, the sashes can be positioned in the middle part of the window opening, allowing better air flow in hot weather. The mobility of the sashes also allows all of the window panes to be cleaned from within the house.
