What zone 4A means for a Centereach window
Centereach falls in IECC climate zone 4A, and ENERGY STAR separately groups Suffolk 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 Centereach.
A New York-Newark-Jersey City, NY-NJ contractor who can't name either one on request is worth a second question before you sign.
