What zone 2A means for a Georgetown window
Williamson County's normal precipitation runs about 37.1 inches a year, with 0.0 inches of snow, which is a separate question from energy performance but still shapes which window details matter in Georgetown.
Moisture and glass performance are handled by different parts of a window's spec sheet, and a Georgetown buyer benefits from checking both instead of assuming one implies the other.
