What zone 5A means for a Wood Dale window
DuPage County's normal precipitation runs about 37.9 inches a year, with 38.4 inches of snow, which is a separate question from energy performance but still shapes which window details matter in Wood Dale.
Moisture and glass performance are handled by different parts of a window's spec sheet, and a Wood Dale buyer benefits from checking both instead of assuming one implies the other.
