Lee's Summit's climate zone, in plain terms
Lee's Summit falls in IECC climate zone 4A, and ENERGY STAR separately groups Jackson 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 Lee's Summit.
A Kansas City, MO-KS contractor who can't name either one on request is worth a second question before you sign.
