Joliet's climate zone, in plain terms
Will County's normal precipitation runs about 38.0 inches a year, with 16.9 inches of snow, which is a separate question from energy performance but still shapes which window details matter in Joliet.
Moisture and glass performance are handled by different parts of a window's spec sheet, and a Joliet buyer benefits from checking both instead of assuming one implies the other.
