Lexington's climate zone, in plain terms
Lexington falls in IECC climate zone 4A, and ENERGY STAR separately groups Fayette 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 Lexington.
A Lexington-Fayette, KY contractor who can't name either one on request is worth a second question before you sign.
