Putnam Valley's climate zone, in plain terms
Putnam Valley falls in IECC climate zone 5A, and ENERGY STAR separately groups Putnam 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 Putnam Valley.
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.
