What zone 4A means for a Sedalia window
Sedalia, MO runs a January average near 29°F and climbs to about 77°F by July, a swing that adds up to roughly 5,261 heating degree days most winters, with 1,187 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in Sedalia, separate from anything a brochure claims.
Zone 4A's requirement is the floor; Sedalia's specific load is what tells you whether beating that floor is worth the extra cost.
