Cedar Falls's climate zone, in plain terms
Black Hawk County's normal precipitation runs about 36.3 inches a year, with 39.1 inches of snow, which is a separate question from energy performance but still shapes which window details matter in Cedar Falls.
Moisture and glass performance are handled by different parts of a window's spec sheet, and a Cedar Falls buyer benefits from checking both instead of assuming one implies the other.
