Jacksonville Beach sits in IECC climate zone 2A, which sets the energy-performance bar here no matter who ends up installing your windows. A window license file doesn't cover Jacksonville Beach on this site, so Google Maps supplies the 5 ranked names you see below. Checked September 2026.

What zone 2A means for a Jacksonville Beach window
Jacksonville, FL runs a January average near 57°F and climbs to about 83°F by July, a swing that adds up to roughly 829 heating degree days most winters, with 3,196 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in Jacksonville Beach, separate from anything a brochure claims.
Zone 2A's requirement is the floor; Jacksonville Beach's specific load is what tells you whether beating that floor is worth the extra cost.
