 Some early windows in modest houses may have had no glazing, but the standard First Period window, until at least 1700, was the diamond-paned casement.No example of this type of window survives "in situ"; all current examples date to (at the very earliest) the late 19th century.Multiple-light, sliding sash windows started to appear around 1700, and by about 1750 had supplanted the earlier type.
