What zone 5A means for a North Strabane window
Pittsburgh, PA runs a January average near 28°F and climbs to about 73°F by July, a swing that adds up to roughly 5,674 heating degree days most winters, with 762 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in North Strabane, separate from anything a brochure claims.
Zone 5A's requirement is the floor; North Strabane's specific load is what tells you whether beating that floor is worth the extra cost.
