Bay & bow windows in Florence, Alabama
Multi-unit assemblies that project outward — bay (3 units, angled) or bow (4–6 units, curved). For Florence's older housing stock (63.1% of homes predate 1980), bay & bow window replacement is a common project — and in the ENERGY STAR South-Central zone, the number that matters most is a low SHGC (≤ 0.23) to block solar heat.
Short answer
Bay & bow windows in Florence typically cost $2,375–$7,595+ 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 Florence 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 Florence's climate
Florence sits in the ENERGY STAR South-Central zone (IECC zone 3A (warm, moist), Lauderdale County), where the priority is a low SHGC (≤ 0.23) to block solar heat.
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 South-Central-zone comfort.

Rebates & incentives in Alabama
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.
Alabama's IRA Home Energy Rebates are administered by ADECA (Alabama Department of Economic and Community Affairs), which as of mid-2026 still lists the HOMES and HEAR programs as under development with no confirmed date for when households can access rebates. If and when they open, windows would generally qualify only through the whole-home HOMES modeled-savings pathway rather than as a direct rebate. Confirm current status with ADECA before relying on it. See our Florence guide for the full program list.
