The History and Evolution of the Sash Window

The origin of the sash window is typically discussed, however it rose to prominence in England during the late 17th century. The term "sash" refers to a single frame that holds panes of glass, which are usually 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" configuration, where six little panes of glass are held together by thick glazing bars on both the leading and bottom sashes.
• Victorian (1837-- 1901): As glass production improved, bigger panes ended up being possible. The "two-over-two" style became popular, frequently including ornamental "horns" on the leading sash to reinforce the frame versus the weight of heavier glass.

• Property Value: Original or top quality replica wood windows can substantially increase the resale worth of a heritage home.

Modern Features in Traditional Frames

Modern wood sash windows are no longer the drafty, rattling fixtures of the past. Expert joiners now incorporate several innovative features:

• Double Glazing: Slimline double-glazing units are now available that fit into traditional profiles, supplying heat retention without sacrificing the window's slender appearance.
