ProVia Bay & Bow Windows
ProVia’s bay & bow windows are energy-efficient, low-maintenance, and built to elevate your home
ProVia’s bay and bow windows are a great way to bring more light and character into your home. Bay windows feature three panels that project outward, creating a charming nook inside and visual interest outside, while bow windows use four or more panels in a gentle curve for a wide, panoramic view. Both styles can be customized with your choice of window types and finishes, and are built with energy-efficient glass and durable vinyl frames for long-term performance and savings.
When it comes to installing these statement windows, JB West is the team you can trust. Our experienced installers ensure a seamless fit and professional finish that enhances both beauty and efficiency. We’ve helped homeowners across the Midwest transform their spaces with ProVia bay and bow windows, and we’re ready to do the same for you.

The craftsmanship was excellent, the people doing the work never stopped until it was all done. The Forman John was great and very nice. he was there to answer any questions. He went all around the house with me for a walk around to inspect the final product. The crew cleaned up the yard of every spec of debris. The price was very fair, and I would recommend JB to anyone without hesitation.
