What zone 5B means for a Boise City window
Boise City falls in IECC climate zone 5B, and ENERGY STAR separately groups Ada County into its Northern 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 Boise City.
A Boise City, ID contractor who can't name either one on request is worth a second question before you sign.

Either way, it's a reasonable question to bring to a Boise City installer before you settle on a product line.
