What zone 5A means for a Palos Heights window
Cook County's normal precipitation runs about 40.9 inches a year, with 38.8 inches of snow, which is a separate question from energy performance but still shapes which window details matter in Palos Heights.
Moisture and glass performance are handled by different parts of a window's spec sheet, and a Palos Heights buyer benefits from checking both instead of assuming one implies the other.
