What is a bay window?

A bay window is a great option to add more space to your home and make any room feel a bit larger. The bay window projects out from the wall of your home and it contains three window units. The middle window is parallel with the wall of your house. In most cases, the middle portion is a picture window giving you optimal views of your yard or scenery. The other two units are usually double-hung or casement windows. The bay window unit adds extra space where it juts out from the house. A bay window is timeless and a great addition to any room.

What is a bow window?

Similar to a bay window, a bow window also projects out from the house. Giving the illusion of more space inside and also offering a unobstructed view outside. The bow window usually contains three to six window united of equal size. The bow window forms a curve by combining the multiple window units. Ventilating casement units are typically selected in a bow window with an optional non-operating picture window as well.
