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

Council Bluffs's climate zone, in plain terms
Council Bluffs falls in IECC climate zone 5A, and ENERGY STAR separately groups Pottawattamie County into its Northern zone for window certification.
Those two numbers, not the brand on the box, set the U-factor and SHGC worth checking on any quote you get in Council Bluffs.
A Omaha, NE-IA contractor who can't name either one on request is worth a second question before you sign.
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 13.9 mi away.

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.
