Fairland's climate zone, in plain terms
Fairland falls in IECC climate zone 4A, and ENERGY STAR separately groups Montgomery 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 Fairland.
A Washington-Arlington-Alexandria, DC-VA-MD-WV contractor who can't name either one on request is worth a second question before you sign.
