What zone 4A means for a West Bradford window
Chester County's normal precipitation runs about 50.9 inches a year, with 30.5 inches of snow, which is a separate question from energy performance but still shapes which window details matter in West Bradford.
Moisture and glass performance are handled by different parts of a window's spec sheet, and a West Bradford buyer benefits from checking both instead of assuming one implies the other.
