What zone 2A means for a Lake Mary window
Lake Mary falls in IECC climate zone 2A, and ENERGY STAR separately groups Seminole 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 Lake Mary.
A Orlando-Kissimmee-Sanford, FL contractor who can't name either one on request is worth a second question before you sign.
