Canoga Park's climate zone, in plain terms
Canoga Park falls in IECC climate zone 3B, and ENERGY STAR separately groups Los Angeles 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 Canoga Park.
A Los Angeles-Long Beach-Anaheim, CA contractor who can't name either one on request is worth a second question before you sign.
