What zone 4B means for a Amarillo window
Amarillo falls in IECC climate zone 4B, and ENERGY STAR separately groups Potter County into its North-Central 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 Amarillo.
A Amarillo, TX 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 7.2 mi away.
Storm and weather risk around Amarillo
Potter County's hail risk sits at Very High and its wildfire risk at Relatively Moderate, according to FEMA's National Risk Index.
Hail risk matters for glass and screen durability in Amarillo; 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 Amarillo installer before you settle on a product line.
