Victorian Wooden Sash Windows 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 often featuring a multi-pane upper sash over a single-pane lower sash, enabling optimum light while retaining a decorative flourish.

3. Paint Seizure and Rattle
Years of over-painting can lead to windows being "painted shut." Alternatively, timber shrinking over a century can cause sashes to fit loosely in their frames, resulting in annoying rattles during windy weather condition.
