Bay Windows

Quality windows designed with diligence

Bay windows extend outside to add space inside

Bay windows jut out beyond your walls to add width to your room with a combination of three windows joined at an angle. They will let in more light and air than flat window styles, since the windows face different directions and reach beyond your walls.

Commonly known as: Oriel window, Projection window, 90-degree angle window, 45-degree bay window, 30-degree bay window, box bay window, square bay window

Bay windows protrude as a group of three angled window panels from the exterior of a house. In comparison, rather than angular, bow windows project from a wall in a curved shape. A wide fixed window in the middle with smaller flanking windows on either side is used in the traditional bay window design.

Bay windows perfectly fit in exterior wall spaces 40 inches wide or larger. They extend further from the house to provide additional space on the interior of the home, possibly allowing a window seat or reading nook for extra seating.

Bay windows are popular with Washington DC homeowners because they can absorb a large amount of natural light from various directions. Bay windows can be built with operable casement windows, enabling better ventilation.
