Bay/Bow Windows

Viwinco Bow
Viwinco 4-Lite Bow Unit: Casement, picture, picture, casement.

Bay and Bow windows are some of the most transformative products that you can add to your home. They project outward from the building envelope and provide full 180-degree views of the outside. These seated windows create a sense of space and openness to any room making it seem larger and more inviting.

What are Bay Windows?

Bay windows come in a variety of different degrees in which they protrude from the exterior of a house. Available in 10-30-45-degrees, bay windows provide ample depth to any room and come with a large seat board, perfect for creating a window seat! In a bay window, only the flanker units (side units) are angles and the center will be parallel to the exterior of the house.

What are Bow Windows?

Bow windows are similar to bay windows in the sense they protrude from the house’s exterior, however, they are always angled at 10-degrees. Bow windows generally have a more-rounded appearance than bay units. These units also come with a large seat board that could be used as a window seat or as a decorative shelf! In contrast to a bay window, all units in a bow are angled at 10-degrees, including the center units.
