What zone 3A means for a Indian Trail window
Charlotte-Concord-Gastonia, NC-SC runs a January average near 42°F and climbs to about 80°F by July, a swing that adds up to roughly 3,061 heating degree days most winters, with 1,715 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in Indian Trail, separate from anything a brochure claims.
Zone 3A's requirement is the floor; Indian Trail's specific load is what tells you whether beating that floor is worth the extra cost.
