What zone 4C means for a Tacoma window

Moisture and glass performance are handled by different parts of a window's spec sheet, and a Tacoma 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 2.3 mi away.
