Grand Rapids's climate zone, in plain terms
Kent County's normal precipitation runs about 39.6 inches a year, with 74.9 inches of snow, which is a separate question from energy performance but still shapes which window details matter in Grand Rapids.
Moisture and glass performance are handled by different parts of a window's spec sheet, and a Grand Rapids 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 2.7 mi away.
What FEMA's risk data says about Grand Rapids
Kent County's hail risk sits at Relatively Moderate and its wildfire risk at Very Low, according to FEMA's National Risk Index.
Hail risk matters for glass and screen durability in Grand Rapids; 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 Grand Rapids installer before you settle on a product line.
