What zone 2A means for a Tomball window
Tomball falls in IECC climate zone 2A, and ENERGY STAR separately groups Montgomery 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 Tomball.
A Houston-Pasadena-The Woodlands, TX contractor who can't name either one on request is worth a second question before you sign.
