Niles's Climate Data and Its Top-Rated Window Pros
Niles sits in IECC climate zone 5A, which sets the energy-performance bar here no matter who ends up installing your windows. A window license file doesn't cover Niles on this site, so Google Maps supplies the 10 ranked names you see below. Checked October 2026.

Niles's climate zone, in plain terms
Cook County's normal precipitation runs about 37.9 inches a year, with 38.4 inches of snow, which is a separate question from energy performance but still shapes which window details matter in Niles.
Moisture and glass performance are handled by different parts of a window's spec sheet, and a Niles buyer benefits from checking both instead of assuming one implies the other.
Data: U.S. EPA / DOE, ENERGY STAR, ENERGY STAR Version 7.0 Climate Zones by County/ZIP (Windows, Doors, and Skylights) (V7.0); Pacific Northwest National Laboratory (DOE Building America), Guide to Determining Climate Zone by County: Building America and IECC 2021 Updates (PNNL-33270) (2021 IECC), from the nearest NOAA station 6.7 mi away.
What FEMA's risk data says about Niles
FEMA rates Cook County's hurricane risk as Very Low and its wind risk as Very High.
Neither rating changes a window's energy label, but both are exactly what impact-resistance and design-pressure ratings are built to answer for a Niles home.
Ask specifically about design pressure and impact rating for Niles, not just energy performance, if either risk rating comes back on the high side.
- Hurricane
- Very Low
- Strong wind
- Very High
- Winter weather
- Very High

The order below weighs a Google rating against its review count, the same way this site weighs a U-factor against a brochure claim: on the number, not the name. Treat it as a rating, never as proof of a license, bond or HVHZ approval.
