What zone 6A means for a West Fargo window
West Fargo falls in IECC climate zone 6A, and ENERGY STAR separately groups Cass County into its Northern 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 West Fargo.
A Fargo, ND-MN contractor who can't name either one on request is worth a second question before you sign.
