Windows

Windows can be an important feature on a building and a contributing detail to the overall architectural style. Windows also have a tendency to be replaced over time with the most up to date styles. When looking at an historic image, it is important to notice what type of windows are present, as they may date later than the building style. For example, an image featuring an 1820s Federal style house with 1/1 windows would likely date after the 1890s, as that was the time that 1/1 windows became available. The numbers in window descriptions refer to the number of panes in each window sash. A 1/1 window (pronounced one-over-one) has one pane in the top sash and one pane in the bottom sash.
