Bay & bow windows in Bend, Oregon
Multi-unit assemblies that project outward — bay (3 units, angled) or bow (4–6 units, curved). For Bend's comparatively newer housing stock (though 22.5% of homes still predate 1980), bay & bow window replacement is a common project — and in the ENERGY STAR Northern zone, the number that matters most is a low U-factor (≤ 0.22) to keep heat in.
Short answer
Bay & bow windows in Bend typically cost $2,900–$9,275+ 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 Bend 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 Bend's climate
Bend sits in the ENERGY STAR Northern zone (IECC zone 5B (cold, dry), Deschutes County), where the priority is a low U-factor (≤ 0.22) 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 Northern-zone comfort.

Rebates & incentives in Oregon
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.
Oregon runs IRA Home Energy Rebate programs alongside long-standing state incentives; windows can qualify within a modeled whole-home efficiency retrofit. Verify current availability first. See our Bend guide for the full program list.
