What zone 5A means for a Tonawanda Town window
Erie County's normal precipitation runs about 40.1 inches a year, with 79.8 inches of snow, which is a separate question from energy performance but still shapes which window details matter in Tonawanda Town.
Moisture and glass performance are handled by different parts of a window's spec sheet, and a Tonawanda Town buyer benefits from checking both instead of assuming one implies the other.
