Addison, TX Climate Specs + Top-Rated Window Installers
ENERGY STAR groups Dallas County into its Southern zone, the U-factor and SHGC target worth checking against any quote you get in Addison. Below that spec discussion sit 10 installers, their order set by Google rating, since Addison is outside this site's window license file. A high rating is worth a look, not a finished decision.

Addison's climate zone, in plain terms
Moisture and glass performance are handled by different parts of a window's spec sheet, and a Addison 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 5.5 mi away.
What FEMA's risk data says about Addison
Dallas County's hail risk sits at Very High and its wildfire risk at Relatively Low, according to FEMA's National Risk Index.
Hail risk matters for glass and screen durability in Addison; wildfire risk matters more for the frame material and nearby vegetation than for the glass itself.
Either way, it's a reasonable question to bring to a Addison installer before you settle on a product line.

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.
