Types of Windows Double-hung windows are the most common type of windows for most architectural styles. Leaded windows contain patterned designs of colored glass. They were popular during the Victorian period and early twentieth century. Composite windows are groupings of windows such as a double-hung window flanked by leaded windows or a set of similar windows. Dormer windows project from the roof of a house to provide light as well as increased floor and head space in a roof area.
Decorative windows come in many shapes and sizes, such as circles or diamonds.
Casement windows open on hinges rather than sliding within a frame, as double-hung windows do. They are often constructed of metal. Sleeping porches have walls that are constructed almost entirely of windows. They are usually located on the rear elevation and often at the second-floor level although they also appear on side elevations and sometimes in front. Foundation windows open into basements and tend to be smaller than windows on primary floors.
