    What are Bow and Bay Windows?

    Bay and bow windows are multi-panel window systems that extend outward from your home’s exterior wall. A bay window typically features three sections with a larger center panel, while a bow window uses four or more panels to create a curved appearance. Both styles increase natural light, expand interior space, and provide wider panoramic views.
