What zone 5A means for a Exeter window
Rockingham County's normal precipitation runs about 52.6 inches a year, with 62.6 inches of snow, which is a separate question from energy performance but still shapes which window details matter in Exeter.
Moisture and glass performance are handled by different parts of a window's spec sheet, and a Exeter buyer benefits from checking both instead of assuming one implies the other.
