Oyster Bay's climate zone, in plain terms
Oyster Bay falls in IECC climate zone 4A, and ENERGY STAR separately groups Nassau County into its North-Central zone for window certification.
Those two numbers, not the brand on the box, set the U-factor and SHGC worth checking on any quote you get in Oyster Bay.
A New York-Newark-Jersey City, NY-NJ contractor who can't name either one on request is worth a second question before you sign.

What FEMA's risk data says about Oyster Bay
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 Oyster Bay home.
Ask specifically about design pressure and impact rating for Oyster Bay, not just energy performance, if either risk rating comes back on the high side.
- Hurricane
- Relatively High
- Strong wind
- Relatively High
- Winter weather
- Very High
