What zone 2B means for a Marana window
Phoenix-Mesa-Chandler, AZ runs a January average near 49°F and climbs to about 85°F by July, a swing that adds up to roughly 2,180 heating degree days most winters, with 2,445 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in Marana, separate from anything a brochure claims.
Zone 2B's requirement is the floor; Marana's specific load is what tells you whether beating that floor is worth the extra cost.
