Bay & bow windows in Evansville, Indiana
Multi-unit assemblies that project outward — bay (3 units, angled) or bow (4–6 units, curved). For Evansville's older housing stock (74% of homes predate 1980), bay & bow window replacement is a common project — and in the ENERGY STAR North-Central zone, the number that matters most is a low U-factor (≤ 0.25) to keep heat in.
Short answer
Bay & bow windows in Evansville typically cost $2,560–$8,195+ installed per opening. The low end is a mid-grade vinyl insert from a regional installer; the top is a premium frame, a full-frame installation, or a full-service national brand.

Is a Bay & bow window right for a Evansville home?
Fixed center with operable flankers (bay) or a curved run of units (bow).
Where it fits:
- Adding interior space, light, and a seat or shelf
- Street-facing façade upgrades
What to weigh:
- A structural project, not a swap — support, roofing, and insulation of the projection drive cost
- Highest cost band of common window projects
Bay & bow windows and Evansville's climate
Evansville sits in the ENERGY STAR North-Central zone (IECC zone 4A (mixed, moist), Vanderburgh County), where the priority is a low U-factor (≤ 0.25) to keep heat in.
Because a bay or bow projects beyond the wall, its roof and floor are a thermal weak point — insulating that projection well matters as much as the glass for North-Central-zone comfort.

Rebates & incentives in Indiana
The federal window tax credit (25C) ended for projects placed in service after December 31, 2025. If your windows were installed in 2025, you can still claim it on your 2025 return — but for new projects there is no federal window credit. State and utility programs are now the main source of window incentives.
Indiana launched the Indiana Energy Saver Program (its IRA HOMES/HEAR implementation) in May 2025 through the Indiana Office of Energy Development, making it one of the earlier states to go live; windows may factor into whole-home HOMES projects via modeled savings, and funding is first-come, first-served — confirm availability at IndianaEnergySaver.com. See our Evansville guide for the full program list.
