What Is The Difference Between Bay and Bow Windows?
Bay and bow windows are similar in some ways, which is why they’re often mixed up, but there are some key differences to keep in mind:
- Bay windows are typically smaller and made up of 3 windows with sharper, angular lines;
- Bow windows are usually larger, made up of 4-6 windows that create a gentle, outward curve.
Both options offer beautiful panoramic views and allow natural light to fill your home. Not sure which one’s the right fit for your home? Contact us to schedule a free in-home consultation with one of our experienced window installers.
