Windows come in many sizes, shapes, and styles. With so many varieties available, it might be confusing as to which type to install. The following definitions may help you see it more clearly.

• Awning window: a unit in which the bottom of the sash swings outward.
• Bay window: a combination of three windows, usually made up of a large center unit and two flanking units at 30 or 45 degree angles to the wall.
• Bow window: a combination of four or more window units in a radial or bow formation.
• Casement window: a window unit in which the single sash cranks outward.
• Double hung: a vertically operable window in which both sashes operate.
