What zone 4A means for a East Lampeter window
Lancaster, PA runs a January average near 31°F and climbs to about 76°F by July, a swing that adds up to roughly 5,129 heating degree days most winters, with 1,030 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in East Lampeter, separate from anything a brochure claims.
Zone 4A's requirement is the floor; East Lampeter's specific load is what tells you whether beating that floor is worth the extra cost.
