Ankeny's Climate Data and Its Top-Rated Window Pros
ENERGY STAR groups Polk County into its Northern zone, the U-factor and SHGC target worth checking against any quote you get in Ankeny. Below that spec discussion sit 9 installers, their order set by Google rating, since Ankeny is outside this site's window license file. A high rating is worth a look, not a finished decision.

Ankeny's climate zone, in plain terms
Polk County's normal precipitation runs about 37.0 inches a year, with 24.7 inches of snow, which is a separate question from energy performance but still shapes which window details matter in Ankeny.
Moisture and glass performance are handled by different parts of a window's spec sheet, and a Ankeny 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 2.6 mi away.
What FEMA's risk data says about Ankeny
FEMA rates Polk 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 Ankeny home.
Ask specifically about design pressure and impact rating for Ankeny, not just energy performance, if either risk rating comes back on the high side.
- Hurricane
- Very Low
- Strong wind
- Very High
- Winter weather
- Relatively 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.
