A sash window or hung sash window is made of one or more movable panels, or “sashes”. The oldest surviving examples of sash windows were installed in England in the s, for example at Ham House. Others see the sash window as a Dutch invention. Louw believed that the sash window was developed in England, but concluded that it was impossible to determine the exact inventor. The sash window is often found in Georgian and Victorian houses, and the classic arrangement has three panes across by two up on each of two sash, giving a six over six panel window, although this is by no means a fixed rule. Innumerable late Victorian and Edwardian suburban houses were built in England using standard sash window units approximately 4 feet 1. To facilitate operation, the weight of the glazed panel is usually balanced by a heavy steel, lead, or cast-iron sash weight or counter-weight concealed within the window frame. The sash weight is connected to the window by a braided cotton sash cord, or a chain, that runs over a pulley at the top of the frame, although spring balances are sometimes used.

They supported the mortice and tenon joints and prevented the sashes from opening too far and becoming jammed. As the Victorian period progressed, architects wanted to use increasingly larger glass panes. Without the glazing bars, a new method of support was needed. Thus, sash horns were born.

Remarkably distinctive thanks to the addition of run-through sash horns, windows present during the Victorian era favoured a two panel grid design on both the top and bottom panes. When it comes to traditional windows, the easiest way to tell which historic period the window belongs is by the astragal bar design. Nowadays it’s possible to design sash windows using these grid patterns with designs such as ‘offset’, ‘borders’ and ‘top grid’ to achieve a truly bespoke window.
With so many designs to choose from, it’s easy to find the right design to suit any style or period of building. Sash windows were originally made using timber frames which could be decorated and assembled using joinery techniques.

The oldest sash windows that are still surviving today date back to the late seventeenth century, but the origins of sash windows have been lost.
Sash windows are a design classic. They’ve been around since the 17th century and they’ve changed very little since their earliest days. The two glazed sashes, which slide vertically in a timber frame, are supported by cords that are balanced with metal weights. The first examples were clunky affairs with thick glazing and heavy frames, but by the 18th century, it was possible to produce thinner, larger sheets of glass and thus the more elegant Georgian-style sashes.
Then, in the s, along came plate glass; and glaziers never looked back. In theory, those original Georgian, Victorian and Edwardian examples should still be going strong; properly and regularly maintained, a sash window should last pretty well indefinitely. The trouble, as most owners of period homes will know, is that over the decades, and indeed centuries, most original windows have suffered from periods of neglect.
If the weather has managed to get to exposed wood, or thick coats of heavy paint have been applied on top of each other without any preparation, a sash window goes from being an appealing and efficient feature to a complete nightmare.
Vertical Sliding Sash Windows
For both the box sash and the spiral balance sliding sash windows, a number of period-matching design details can be incorporated. In the past it was not possible to achieve good energy-efficiency without having over-thick glazing bars. Within the glass sandwich of the glazing unit there is a grid of spacer bars that exactly matches the glazing bars applied to the surface.
The history of the sash window dates back to the 16th century where surviving examples at Ham House can still be seen.
Nevertheless, whoever it was that came up with the idea in the first place has left a lasting legacy in the form of these striking and elegant windows. The type of sash window people tend to visualise is the classic Georgian design of six over six, where each section of the window is three panes of glass wide by two panes deep.
However, there are no restrictions as to how many panes there should be or how they are arranged. The only requirement of a sash window is that it should open vertically rather than horizontally as casement windows do. This offers several advantages, including being able to have the window open without directing so much wind and rain into the room, and of course, they have a timeless, elegant appearance that appealed to wealthier citizens.
There are several methods by which you can move the opening window section, and one of the oldest is the use of holes with wooden pegs at regular intervals that the weight of the window could rest on. This then developed into the use of pulleys and weights, known as the counterbalanced sash. The use of sash windows was predominant in the Georgian and Victorian eras, and designs changed over this period to reflect technological developments.
For example, the older Georgian windows had small panes of glass with large glazing bars, due to the limited quality of glass production and the glass having insufficient strength at that time. The Victorians were able to manufacture far higher quality glass, which meant they could use larger panes and slim down the size of the glazing bars. Stained glass versions also started to become popular during this time, and there are some striking examples in buildings dating from this period.
Sadly, many original windows have been destroyed or removed as buildings have been demolished or renovated. However, the importance of retaining the visual authenticity of a period building is becoming more well-recognised in helping to preserve the heritage of the nation.
