Clearfield sits in IECC climate zone 5B, which sets the energy-performance bar here no matter who ends up installing your windows. A window license file doesn't cover Clearfield on this site, so Google Maps supplies the 8 ranked names you see below. Checked October 2026.

5BIECC climate zone · ENERGY STAR Northern zone
Clearfield's climate zone, in plain terms
Clearfield falls in IECC climate zone 5B, and ENERGY STAR separately groups Davis 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 Clearfield.
A Ogden, UT contractor who can't name either one on request is worth a second question before you sign.
