The architectural style of the 18th and 19th centuries is closely associated with Sash Windows. Their popularity stemmed from their larger panes of glass and more elegant proportions than casement windows.

After years of controversy, experts now believe they were originally invented in Yorkshire.Sash windows were designed to allow a small gap for ventilation without letting in the rain, and were also less prone to rotting and distortion due to their enclosure within a box.

Sash windows offered both practical advantages and a more pleasing style than older window designs, and they were popular in both new buildings and as stylish replacements in existing homes..During the Georgian era, sash windows became what they are today, with the development of the two moving sashes.

Glass remained expensive and was marked with large bull’s eye patterns in the centre of each pane due to the way it was made. As better methods of making large panes were found, windows with six panels in each sash appeared, becoming characteristic of the Georgian sash window..

The popularity of these windows have remained strong during the Victorian age, but they were ornamented with elaborate decorations.Victorian houses often have large bay windows and elegantly proportioned façades with the windows getting gradually smaller as their height from the ground increases.

Sashes with four panes of glass are another mark of the Victorian window. The wealthy often chose to have older styles of window added to their property to distinguish themselves from the increasingly common use of plate glass sash windows with the slimmer glazing bars that were once prized.

Despite their popularity at the start of the 20th century, sash windows have become less common during the last hundred years, with cheaper, less labour intensive types of window being used instead.. Modern versions of the sash window preserve the traditional character of older properties, while combining all the latest developments in manufacturing processes with the grace and practicality that this style epitomizes.
