What zone 5A means for a Westfield window
Springfield, MA runs a January average near 25°F and climbs to about 73°F by July, a swing that adds up to roughly 6,330 heating degree days most winters, with 677 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in Westfield, separate from anything a brochure claims.
Zone 5A's requirement is the floor; Westfield's specific load is what tells you whether beating that floor is worth the extra cost.
