Custom ProVia Bay and Bow Windows for Arizona Homes
Bay and bow windows can add natural light, dimension, and a more open feel to a room. But when the existing window starts leaking air, fogging between panes, pulling out of square, or failing around the corners, small repairs usually only go so far.
Everlasting Window & Door has helped Arizona homeowners replace windows since 1995. We install custom ProVia bay and bow windows built to fit your existing opening, then handle the project from measurement through installation. Our goal is simple: restore the seal, improve performance, and give the room a window that looks and works the way it should.
We also install awning, casement, single-hung, and double-hung windows for homeowners who are comparing styles.

Bay vs. Bow Windows: What’s the Difference?
Bay and bow windows are both projecting window styles, but they create different looks and feels.
Bay Windows
A bay window uses three window panels. The center panel is usually larger and sits flat, while the two side panels are angled at 30 or 45 degrees. This creates a more defined projection from the home and often provides a deeper interior ledge or seat area. Bay windows work well when you want a stronger architectural feature, more usable interior space, or a window seat.
Bow Windows
A bow window uses four or more panels arranged in a gentle curve. Because of that curved shape, bow windows tend to feel softer and more gradual than bay windows. They are often a good fit for wider wall openings or rooms where you want added light without a projection that is as deep or as angular.
Key Differences
Panel Count: Bay windows use three panels, while bow windows use four or more.
Shape: Bay windows project at angles, while bow windows create a curved arc.
Interior Space: Bay windows typically provide a deeper ledge or seating area.
Best Fit: Bow windows often work better for wider openings.
Overall Look: Bay windows feel more architectural, while bow windows feel softer and more rounded.
During your estimate, we’ll look at your opening, talk through how you want the room to function, and help you decide which configuration makes the most sense.
ProVia Bay and Bow Window Options
ProVia bay and bow windows are built to order, which matters for replacement projects. Existing openings aren’t always perfectly standard, and projecting windows need to fit correctly to perform well over time.
Available options include:
Frame Materials: Vinyl, fiberglass, or wood-composite options
Glass Packages: Double- or triple-pane glass with Low-E coating options
Exterior Finishes: Multiple colors and cladding options
Grid Patterns: Several divided-light styles
Hardware Finishes: Coordinating finish options for a clean final look
Because bay and bow windows include more glass area than standard flat windows, glass performance matters. Low-E glass can help reduce solar heat gain while still allowing natural light into the room. ProVia windows also carry NFRC certification and meet AAMA testing standards for verified performance.
What to Expect During Bay or Bow Window Replacement
Replacing a bay or bow window is more involved than replacing a standard flat window. The window projects outward from the home, so the installation needs to account for the frame, seat board, roof area, support points, and weather sealing.
Here’s how our process typically works:
Free Estimate and Measurements
We start with a free estimate, measure the existing opening, and discuss bay and bow window configurations, finishes, and glass options.
Custom Window Ordering
Once the details are confirmed, your ProVia window is built to your opening’s exact dimensions. Because each unit is custom-made, production time is required before installation can be scheduled.
Existing Window Removal
On installation day, we remove the existing bay or bow window assembly and inspect the rough opening and surrounding framing.
Framing and Opening Preparation
If the framing, roof area, knee wall, or seat board needs attention, we address those details before setting the new unit.
New Window Installation
The new ProVia window is leveled, secured, sealed, and fastened at all required installation points. We complete the interior and exterior finishing details, paying close attention to corners, seams, and weather protection.
Discounts, Financing, and Special Programs
Bay and bow window replacement is a larger investment than many standard window projects, so we offer financing options for qualifying homeowners.
Veterans and senior homeowners may also qualify for available discounts. Through our Mission Windows and Doors program, a portion of project costs helps provide free windows and doors for veterans in need. Mention any applicable discount when you request your estimate.
