What are Sash Windows?

A common form of window frames for hundreds of years, sash means a single frame for glazing. By balancing a counterweight hidden within the frame with the weight of the sash, this simple system allows you to safely and easily open and close windows, whilst offering timeless elegance. You can find sash windows that slide both horizontally and vertically, depending on the period of your house, so it’s important to do your research and find out what type of sash windows suit the era of your house. 

Different Periods of Sash Windows

As you would expect, when a certain feature has been popular over such a long time as the sash window, there are plenty of variations. One of the easiest ways to tell what period your sash windows come from is by looking at the number of panes of glass in the window. The further back you go in time, the more difficult it was to produce large panes of glass, so older versions were made up of more individual panes. Georgian houses tend to feature “6 over 6” frames, whereas Victorian houses would use “2 over 2” and Edwardian, “6 over 2”. While the distinction might seem small, it does make a big difference to the aesthetics of the house, and you need to ensure that your choice of sash window is in keeping with the style of the house.
