Barnstable's climate zone, in plain terms
Barnstable County's normal precipitation runs about 45.7 inches a year, with 21.5 inches of snow, which is a separate question from energy performance but still shapes which window details matter in Barnstable.
Moisture and glass performance are handled by different parts of a window's spec sheet, and a Barnstable buyer benefits from checking both instead of assuming one implies the other.
