What zone 5A means for a Clarkstown window
Rockland County's normal precipitation runs about 51.2 inches a year, with 32.7 inches of snow, which is a separate question from energy performance but still shapes which window details matter in Clarkstown.
Moisture and glass performance are handled by different parts of a window's spec sheet, and a Clarkstown buyer benefits from checking both instead of assuming one implies the other.
