Georgian Windows (1714-- 1837): Characterized by the "six-over-six" pane setup, using small panes of glass held together by thin glazing bars due to the constraints of glass-making technology at the time.Victorian Windows (1837-- 1901): As glass production enhanced, larger panes became popular. Victorian sash windows often include "two-over-two" designs with decorative "horns" to support the weight of much heavier glass.Edwardian Windows (1901-- 1910): A hybrid style frequently featuring a multi-pane upper sash over a single-pane lower sash, enabling optimum light while maintaining an ornamental flourish.

Standard single glazing and the inherent gaps required for sash windows to move efficiently result in substantial heat loss. This typically results in a cold living environment and high energy expenses.
3. Paint Seizure and Rattle
Years of over-painting can cause windows being "painted shut." Conversely, lumber shrinking over a century can cause sashes to fit loosely in their frames, resulting in annoying rattles throughout windy weather.

Glazing Upgrades
While numerous select to maintain original crown glass for its "wavy" visual, others select "slimline" double glazing. These units are thin adequate to fit into initial sash profiles, offering the thermal advantages of modern-day windows while maintaining the thin glazing bars vital for a period appearance.
