The history of the sash window
There cannot be a more quintessential style of window. Simple in design, elegant in proportion, sash windows remain the most beautiful and efficient style ever made.
First introduced in the mid 1600’s this evocative style soon became very fashionable. Rich merchants would build grand town houses and stately mansions to display their wealth to their peers. The larger the glazed area the wealthier they were. Replacement of windows was prevalent even in the 18th century. Glorious new sash windows replaced casement windows in 16th century properties.
By faithfully blending the beauty, proportions and elegance of traditional sash windows with today’s modern materials and manufacturing techniques The Bygone Collection have created stunningly authentic sash windows capable of meeting today’s stringent requirements.
Read on to discover how Bygone creates bespoke, purpose made, individually designed sash windows, custom built to your precise specifications and installed by craftsmen with pride – faithful to the spirit of the past 400 years of history.
The Great Fire
Sash windows are probably responsible for shaping the architecture of many buildings following the great fire of 1666.
Soon after the fire, London changed its Building Regulations to prevent the spread of fire in the future as the many timber signs, beams and windows accelerated the spread of the fire.
Victorian sash windows
The industrious Victorian era perfected glass production techniques, enabling larger panes of glass to be produced. Consequently the Victorians were able to create far larger sash windows, with larger panes of glass and often just a single glazing bar.
The 1880’s saw the revival of Queen Anne style (marginal pane glazing bars), which became established as “the” design right through to the early 20th century.
Georgian era
The Georgian era is perhaps the most elegant of periods for sash windows.In the late 1600’s and early 1700’s the classic “6 over 6” window became the norm with windows getting larger and larger throughout the 1700’s – although still with small panes as dictated by the glass manufacturing techniques of the time.
