What zone 4C means for a Eastmont window
Eastmont falls in IECC climate zone 4C, and ENERGY STAR separately groups Snohomish 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 Eastmont.
A Seattle-Tacoma-Bellevue, WA contractor who can't name either one on request is worth a second question before you sign.
