 oors and windows provide your house with access, light and ventilation. Along with shutters,
windows and doors also provide aesthetic and architectural detailing to the structure.
The word "window" may have been derived from "wind hole," the term that described the openings on
early structures that provided ventilation from internal fires. The earliest homeowners covered these
"wind holes" with fabric or wood, since glass was rare and expensive until later in the 17th century.
When glass became more available, it was first only used in small panes. The size of windowpanes increased
through the 18th and 19th centuries because of improvements in technology and a decrease in cost. Windows
are usually categorized by the number of lights, or panes of glass, found in each sash. For instance, a
six-over-six light, double hung sash window consists of 12 panes.
 Anatomy of windows and doors
Shutters are a commonly used architectural element on historic houses, especially here in Charleston where
they provided shade from direct sun, as well as protection against intruders and weather events such as
hurricanes. The two most common types of shutters are paneled and louvered.
The front door of a residence and its detailing make up one of the most important architectural statements
about a house. Doors on historic houses are overwhelmingly made of wood and consist of pieces of wood joined
together in various configurations.
Guidelines To Keep In Mind About Your Doors, Windows And Shutters
- Replacement doors, windows and shutters that match the originals are generally expensive and need to be custom-made. Thus one should repair existing doors, windows and shutters, retaining as much historic fabric as possible. If the pieces are beyond repair, exact replicas should be installed.
- If only a few shutters remain on a building, they should be placed on the front façade. Existing shutter hardware should be retained, even if the shutters are missing. Shutters should open and close and be constructed of wood. Shutters that are fixed (do not open and close) or are constructed of synthetic material such as fiberglass or vinyl are not acceptable.
- If window replacements are required, they should match the configuration of the original windows. For example, if the original windows had six-over-six lights, the replacement windows should also.
- Replacement windows should match the originals in materials (usually wood) and have true divided lights. Simulated divided light windows and windows constructed of synthetic materials such as aluminum and vinyl are not acceptable on historic buildings.
