Styles of Windows

Bay Window:  A set of two or more windows that protrude out from the wall. The window is moved away from the wall to provide more light and wider views. 

Casement Window: A window that opens by swinging inward or outward much like a door. Casement windows are usually vertical but are often grouped in bands.

Clapboard: Also known as siding or weatherboard. Long, narrow boards overlapped to cover the outer walls. Used in Colonial style frame houses.

Dormer: The setting for a vertical window in the roof. Called a gable dormer if it has its own gable or a shed dormer if it has a flat roof. Most often found in upstairs bedrooms.

Eaves: That portion of the roof that projects beyond the wall.

Fanlight:  A semicircular or arched window above a door.

Palladian Window: A three part window featuring a large arched center and flanking rectangular sidelights.

Pediment: A triangular  crown used over doors, windows, or porches. A classical style.

Portico: A large porch usually with a pedimented roof supported by classical columns or pillars.  

Rafter: A roof beam sloping from the ridge to the wall. In most houses, rafters are only visible from the attic. In styles such as craftsman bungalows and some "rustic" contemporaries, they are exposed.

Sidelights: Windows on either side of a door.

Turret: A small tower, often at the corner of a building. Common in Queen Anna styles among others. A turret is a smaller structure while a tower begins at ground level.
