What zone 4A means for a Syosset window
Moisture and glass performance are handled by different parts of a window's spec sheet, and a Syosset 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 0.7 mi away.
Storm and weather risk around Syosset
FEMA rates Nassau County's hurricane risk as Relatively High and its wind risk as Relatively High.
Neither rating changes a window's energy label, but both are exactly what impact-resistance and design-pressure ratings are built to answer for a Syosset home.
Ask specifically about design pressure and impact rating for Syosset, not just energy performance, if either risk rating comes back on the high side.
- Hurricane
- Relatively High
- Strong wind
- Relatively High
- Winter weather
