What zone 4C means for a Vancouver window

Moisture and glass performance are handled by different parts of a window's spec sheet, and a Vancouver 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 3.1 mi away.

Storm and weather risk around Vancouver

FEMA scores Clark County's winter-weather risk as Relatively Moderate and its flood risk as Relatively Moderate.

Winter risk in Vancouver weighs on U-factor and condensation resistance; flood risk weighs more on sill height and drainage detailing than on the glass package.

Treat these as two separate conversations with a Vancouver contractor, not one.

Strong wind: Relatively Moderate
Winter weather: Relatively Moderate

Data: FEMA, National Risk Index for Natural Hazards - County-level table, v1.20 (v1.20, December 2025).
