Specialty shapes windows in Chicago, Illinois
Arches, circles, eyebrows, and custom geometric shapes — usually fixed. For Chicago's older housing stock (76.5% of homes predate 1980), specialty shapes 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
Specialty shapes windows in Chicago typically cost $695–$3,480+ 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.

Specialty shapes windows and Chicago's climate
Chicago sits in the ENERGY STAR Northern zone (IECC zone 5A (cool, moist), Cook County), where the priority is a low U-factor (≤ 0.22) to keep heat in.
With no operable joints to leak, a specialty shapes window delivers the best whole-unit efficiency of any style — the easiest way to clear the Northern-zone target of U-factor 0.22 or lower. Pair it with operable units where you need ventilation or bedroom egress.

What Specialty shapes windows cost in Chicago
Specialty shapes window replacement in Chicago runs $695–$3,480+ installed. 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. Labor rates in metro Chicago run above the national average, and the housing stock pushes jobs toward the more involved end of the range. Old masonry openings, plaster returns, and original wood sashes rarely accept a simple insert cleanly, so careful full-frame replacement - with attention to flashing, weatherproofing, and matching the existing profile - is common. Budget for city permit steps where the work goes beyond in-kind replacement, and for longer timelines and possible design constraints if the home sits in a landmark district.

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.
