What zone 5A means for a Monroeville window
Pittsburgh, PA runs a January average near 30°F and climbs to about 75°F by July, a swing that adds up to roughly 5,490 heating degree days most winters, with 945 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in Monroeville, separate from anything a brochure claims.
Zone 5A's requirement is the floor; Monroeville's specific load is what tells you whether beating that floor is worth the extra cost.
