What zone 5A means for a Mequon window
Ozaukee County's normal precipitation runs about 34.4 inches a year, with 54.3 inches of snow, which is a separate question from energy performance but still shapes which window details matter in Mequon.
Moisture and glass performance are handled by different parts of a window's spec sheet, and a Mequon buyer benefits from checking both instead of assuming one implies the other.
