The "two-over-two" design became popular, typically including decorative "horns" on the leading sash to strengthen the frame against the weight of heavier glass.Edwardian (1901-- 1914): A hybrid design typically emerged, including a multi-pane leading sash over a large, single-pane bottom Authentic Sash Windows to optimize light.How Wooden Sash Windows Function
