What zone 5A means for a Malden window
Malden falls in IECC climate zone 5A, and ENERGY STAR separately groups Middlesex 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 Malden.
A Boston-Cambridge-Newton, MA-NH contractor who can't name either one on request is worth a second question before you sign.
