What zone 5A means for a Detroit window
Detroit falls in IECC climate zone 5A, and ENERGY STAR separately groups Wayne County into its Northern 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 Detroit.
A Detroit-Warren-Dearborn, MI contractor who can't name either one on request is worth a second question before you sign.
