The History and Evolution of the Sash Window

The origin of the sash window is often debated, however it increased to prominence in England throughout the late 17th century. The term "sash" refers to a single frame that holds panes of glass, which are generally separated by glazing bars. Unlike casement windows that open on a hinge, sash windows slide vertically or horizontally.

Architectural Eras

• Georgian (1714-- 1837): Known for the "six-over-six" setup, where 6 small panes of glass are held together by thick glazing bars on both the leading and bottom sashes.
• Victorian (1837-- 1901): As glass manufacturing improved, larger panes ended up being possible. The "two-over-two" style became popular, often featuring ornamental "horns" on the top sash to reinforce the frame against the weight of heavier glass.
• Edwardian (1901-- 1914): A hybrid design frequently emerged, featuring a multi-pane top sash over a big, single-pane bottom sash to optimize light.
