What zone 3B means for a Roseville window

Roseville falls in IECC climate zone 3B, and ENERGY STAR separately groups Placer County into its North-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 Roseville.

A Sacramento-Roseville-Folsom, CA contractor who can't name either one on request is worth a second question before you sign.
