What zone 4A means for a Westerville window
Columbus, OH runs a January average near 30°F and climbs to about 75°F by July, a swing that adds up to roughly 5,108 heating degree days most winters, with 1,096 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in Westerville, separate from anything a brochure claims.
Zone 4A's requirement is the floor; Westerville's specific load is what tells you whether beating that floor is worth the extra cost.
