Cheltenham's climate zone, in plain terms
Philadelphia-Camden-Wilmington, PA-NJ-DE-MD runs a January average near 34°F and climbs to about 79°F by July, a swing that adds up to roughly 4,466 heating degree days most winters, with 1,375 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in Cheltenham, separate from anything a brochure claims.
Zone 4A's requirement is the floor; Cheltenham's specific load is what tells you whether beating that floor is worth the extra cost.
