What zone 4B means for a Shingle Springs window
Shingle Springs falls in IECC climate zone 4B, and ENERGY STAR separately groups El Dorado 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 Shingle Springs.
