What zone 6A means for a Essex Junction window
Burlington-South Burlington, VT runs a January average near 19°F and climbs to about 71°F by July, a swing that adds up to roughly 7,306 heating degree days most winters, with 568 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in Essex Junction, separate from anything a brochure claims.
Zone 6A's requirement is the floor; Essex Junction's specific load is what tells you whether beating that floor is worth the extra cost.
