Victorian sash windows often include "two-over-two" designs with ornamental "horns" to support the weight of heavier glass.Edwardian Windows (1901-- 1910): A hybrid style typically including a multi-pane upper sash over a single-pane lower Double-Hung Sash Windows, permitting optimum light while maintaining an ornamental grow.

This essentially removes rattles and significantly lowers heat loss without changing the window's appearance.
Glazing Upgrades
While numerous select to keep initial crown glass for its "wavy" aesthetic, others go with "slimline" double glazing. These units are thin adequate to suit original sash profiles, providing the thermal benefits of contemporary windows while keeping the thin glazing bars necessary for a period look.
