Great windows are a powerful selling point
Windows bring light and air
to an interior space and provide a view of the outdoor scenery. In older houses,
windows may have just one layer of glass per pane, which is called single
glazing. More contemporary and energy efficient windows have two layers of glass
per pane, or double glazing. Low-emission glass, referred to as "Low-E" glass,
has a special coating that allows light to enter a room but prevents heat from
escaping; this is used to conserve energy.
Bay windows project from the side of a house, adding light and extra square
footage to a room. The area inside a bay window creates a cozy nook well-suited
for a window seat or a dining area.
Box bay windows

Bow windows project from the side of a building like bay windows, only with a
curved shape. It's typically more expensive to build a bow window than a bay

versatile, as you can open it a little or a lot from either the top or the

or window. Label molding was used in Gothic and
windows are a row of windows separated by vertical posts, called mullions.
Ribbon windows can be used up high on a wall to bring added light to a room.
Windows installed near the ceiling like this are called clerestory windows.
Oriel windows project
from the side of a building, like a bay window, but are located on the second
floor or higher and supported by brackets or columns. Oriel windows bring added
light and space into a room and have been used in many styles of architecture.
Paired windows are two
windows next to each other often times under an arch. The support between the
windows is called a mullion.

typically in Gothic architecture, was used to protect the archway from
rainwater. It also serves as a decorative frame for the top of an arch.

this window design in developing what is known as the Palladian style of
architecture. This window will be a focal point in a room and has been widely
used in a variety of traditional architectural styles.
