What zone 2B means for a Glendale window
Glendale falls in IECC climate zone 2B, and ENERGY STAR separately groups Maricopa County into its Southern 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 Glendale.
A Phoenix-Mesa-Chandler, AZ contractor who can't name either one on request is worth a second question before you sign.
