What zone 5B means for a Pueblo West window
Pueblo, CO runs a January average near 32°F and climbs to about 77°F by July, a swing that adds up to roughly 5,292 heating degree days most winters, with 1,091 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in Pueblo West, separate from anything a brochure claims.
Zone 5B's requirement is the floor; Pueblo West's specific load is what tells you whether beating that floor is worth the extra cost.
