What Florida Homeowners Need to Know About Energy Star Windows

Why Energy Star Matters More In Florida Heat

Energy Star windows are not just about saving on the electric bill, they are about reducing the amount of heat that gets pushed into the house all afternoon.

That matters because a window that looks fine from the street can still be underperforming badly once the sun hits the glass and the air conditioner starts fighting the load.

In practice, the most useful numbers are the U-factor and the solar heat gain coefficient, especially when you are comparing options for Florida heat and humidity.
