Iona 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 Iona on this site, so Google Maps supplies the 7 ranked names you see below. Checked September 2026.

What zone 2A means for a Iona window
Cape Coral-Fort Myers, FL runs a January average near 65°F and climbs to about 83°F by July, a swing that adds up to roughly 252 heating degree days most winters, with 4,046 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in Iona, separate from anything a brochure claims.
Zone 2A's requirement is the floor; Iona's specific load is what tells you whether beating that floor is worth the extra cost.
