What zone 3A means for a Wake Forest window
Wake Forest falls in IECC climate zone 3A, and ENERGY STAR separately groups Wake 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 Wake Forest.
A Raleigh-Cary, NC contractor who can't name either one on request is worth a second question before you sign.
