Vernon Hills's climate zone, in plain terms
Lake County's normal precipitation runs about 38.5 inches a year, with 43.1 inches of snow, which is a separate question from energy performance but still shapes which window details matter in Vernon Hills.
Moisture and glass performance are handled by different parts of a window's spec sheet, and a Vernon Hills buyer benefits from checking both instead of assuming one implies the other.
