Slidell's climate zone, in plain terms
Slidell falls in IECC climate zone 2A, and ENERGY STAR separately groups St. Tammany Parish 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 Slidell.
A Slidell-Mandeville-Covington, LA contractor who can't name either one on request is worth a second question before you sign.
