What zone 3A means for a Greensboro window
Greensboro falls in IECC climate zone 3A, and ENERGY STAR separately groups Guilford County into its South-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 Greensboro.
A Greensboro-High Point, NC contractor who can't name either one on request is worth a second question before you sign.
