What zone 4A means for a Olathe window
Johnson County's normal precipitation runs about 40.7 inches a year, with 13.8 inches of snow, which is a separate question from energy performance but still shapes which window details matter in Olathe.
Moisture and glass performance are handled by different parts of a window's spec sheet, and a Olathe 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 3.3 mi away.
