What zone 6A means for a Sault Ste. Marie window
Sault Ste. Marie, MI runs a January average near 16°F and climbs to about 66°F by July, a swing that adds up to roughly 8,457 heating degree days most winters, with 236 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in Sault Ste. Marie, separate from anything a brochure claims.
Zone 6A's requirement is the floor; Sault Ste. Marie's specific load is what tells you whether beating that floor is worth the extra cost.
