What zone 4A means for a Lower Southampton window
Lower Southampton falls in IECC climate zone 4A, and ENERGY STAR separately groups Bucks 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 Lower Southampton.
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.
