What zone 3B means for a Wildomar window
Wildomar falls in IECC climate zone 3B, and ENERGY STAR separately groups Riverside 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 Wildomar.
A Riverside-San Bernardino-Ontario, CA contractor who can't name either one on request is worth a second question before you sign.
