The story of Sash Windows
Sash windows are surely the quintessential style of window in the UK.
Simple yet elegant, in our opinion, they remain both the most beautiful and efficient design ever created. Other styles of windows will almost certainly look out of place in Georgian, Regency or Victorian properties.
By faithfully reproducing the elegance of traditional timber construction with modern materials and energy efficient glazing, each Bygone window allows you to enjoy stunningly authentic styles that blend perfectly into your home, whilst living up to modern expectations.

Sash windows were first installed nearly 400 years ago. They were originally propped open with wedges or timber dowels until someone decided to open them with rope, like a drawbridge.
PROGRESS IN GLASS PRODUCTION
Glass has played an important part in the development of sash windows, being more expensive than gold when it was first used! The challenge has been to make cheaper glass and larger panes, thus eliminating the need for astragal glazing bars to hold the glazing in place.
As glass became cheaper, the transition from small diamond shaped lead lights, to Georgian squares and finally on to larger Victorian sheet glass, was eventually hung on chains because the weight had increased so considerably.
Planning legislation has also had a huge influence on the style and design of our period buildings in some surprising ways, and none more so than the great fire of London.
THE INFLUENCE OF THE GREAT FIRE
The Great Fire of London in 1666 played a pivotal role in sash window design. Soon after the event, the capital changed its building regulations to prevent the future spread of fire. These new guidelines called for timber window frames to be recessed behind the outside stone or brick facade, leading to the development of Georgian architecture, which incorporated sash windows as the most advanced window of their time.
A FASHION STATEMENT
This evocative style quickly became highly chic. Rich merchants built grand town houses and stately homes to display their wealth. To discover how wealthy a particular family was, just look at the glazing; the larger the glazed area, the greater the owner’s fortune. There was a huge rush for prestigious sash window styles that consequently replaced outdated casement windows.
THE GEORGIAN ERA
This era was probably the most elegant period for our preferred design. During the late 1600s and early 1700s, the classic six over six pane style was considered the norm. During the 1700s windows became increasingly larger, however, panes remained small throughout this period, dictated by glass manufacturing techniques of the time.
THE QUEEN ANNE PERIOD
During the 1880s marginal pane glazing bars were established as the style of choice until the early 20th century.
THE VICTORIAN ERA
Manufacturers were able to produce larger panes with more advanced glass production techniques. Consequently window sizes were larger too, using bigger panes and often just one single glazing bar.
