What zone 5B means for a Brighton window
Adams County's normal precipitation runs about 14.1 inches a year, with 34.5 inches of snow, which is a separate question from energy performance but still shapes which window details matter in Brighton.
Moisture and glass performance are handled by different parts of a window's spec sheet, and a Brighton buyer benefits from checking both instead of assuming one implies the other.
Data: U.S. EPA / DOE, ENERGY STAR, ENERGY STAR Version 7.0 Climate Zones by County/ZIP (Windows, Doors, and Skylights) (V7.0); Pacific Northwest National Laboratory (DOE Building America), Guide to Determining Climate Zone by County: Building America and IECC 2021 Updates (PNNL-33270) (2021 IECC), from the nearest NOAA station 2.7 mi away.

Either way, it's a reasonable question to bring to a Brighton installer before you settle on a product line.
