Canyon Lake's climate zone, in plain terms
Canyon Lake falls in IECC climate zone 2A, and ENERGY STAR separately groups Comal County into its Southern 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 Canyon Lake.
A San Antonio-New Braunfels, TX contractor who can't name either one on request is worth a second question before you sign.
