Georgian Windows (1714-- 1837): Characterized by the "six-over-six" pane setup, using little panes of glass held together by thin glazing bars due to the restrictions of glass-making technology at the time.Victorian Windows (1837-- 1901): As glass manufacturing enhanced, larger panes became popular. Victorian sash windows often feature "two-over-two" styles with decorative "horns" to support the weight of much heavier glass.Edwardian Windows (1901-- 1910): A hybrid design often including a multi-pane upper sash over a single-pane lower sash, enabling maximum light while keeping a decorative grow.

This practically removes rattles and significantly decreases heat loss without modifying the window's look.
Glazing Upgrades
While many pick to keep initial crown glass for its "wavy" aesthetic, others decide for "slimline" double glazing. These systems are thin sufficient to fit into original sash profiles, offering the thermal advantages of contemporary windows while preserving the thin glazing bars vital for a period look.
