What zone 4A means for a East Whiteland window
East Whiteland falls in IECC climate zone 4A, and ENERGY STAR separately groups Chester County into its North-Central 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 East Whiteland.
A Philadelphia-Camden-Wilmington, PA-NJ-DE-MD contractor who can't name either one on request is worth a second question before you sign.
