What zone 3A means for a Chesapeake window
Virginia Beach-Chesapeake-Norfolk, VA-NC runs a January average near 44°F and climbs to about 83°F by July, a swing that adds up to roughly 2,810 heating degree days most winters, with 2,130 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in Chesapeake, separate from anything a brochure claims.
Zone 3A's requirement is the floor; Chesapeake's specific load is what tells you whether beating that floor is worth the extra cost.
