The design of Georgian sash windows was heavily influenced by the "Golden Ratio," making sure that windows were completely proportioned to the facade of the building. Due to the restrictions of glass production at the time, big sheets of glass were impossible to produce. Rather, little panes (called "lights") were joined together by wood glazing bars (astragals).
Key Milestones in Sash Window EvolutionLate 17th Century: Introduction of the vertical sliding mechanism utilizing weights and sheaves.Early 18th Century: Thick glazing bars prevailed to support heavy, hand-blown glass.Mid-18th Century: Glazing bars became thinner and more fragile as glass-making methods enhanced.1774 Building Act: Regulations required window frames to be recessed into the brickwork to prevent the spread of fire, creating the "reveal" look typical in London balconies.Anatomy and Characteristics
