What zone 2A means for a Grand Prairie window
Grand Prairie falls in IECC climate zone 2A, and ENERGY STAR separately groups Dallas 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 Grand Prairie.
A Dallas-Fort Worth-Arlington, TX 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 Grand Prairie installer before you settle on a product line.
