Sash Windows

Sash windows have a single frame for glazing. Traditional sash windows feature two sashes that will slide up and down. Windows work by balancing the sash with counterweights. Traditional sash windows are found in Victorian or Georgian properties but can also be seen with different variations in late Edwardian and Victorian homes. A popular variation includes a sliding sash that is horizontal and is known as a slider window. The design does predate the vertical sash but it uses the same sliding mechanism.
                         
When replacing sash windows, it’s important to note that there are different styles and you should be getting the time period right. There have been several developments and style changes to sash windows over the years.
                         
Traditional sash windows consist of a number of small panes. Glazing bars that create a larger-glazed area holds them together. This is due to glass advancements at the time not allowing very large expanses of clear glazing.
                         
Georgian: This is a six-over-six style but larger eight-over-eight windows were also common for this time period.
                         
Victorian: A two-over-two design was what was popular in Victorian times. However, other configurations were also popular throughout the whole period. This also includes sash windows that had just a single light and the inclusion of sidelights.
                         
Edwardian: A six-over-two pane design was the most common configuration during this time period but just like with the Victorian period, this period also saw different variations in style.
                         
There were also other varieties used in different eras. Venetian windows consisted of a central sliding sash that was fixed between two panes on either side. The Queen Anne Revival style had several panes in the upper sash but only one or two in the lower. During the Gothic or Regency periods, sashes were usually arched instead of rectangular. In some regions, it was more popular to have horizontally sliding sashes.
