What zone 6A means for a Crystal window
Minneapolis-St. Paul-Bloomington, MN-WI runs a January average near 16°F and climbs to about 73°F by July, a swing that adds up to roughly 7,654 heating degree days most winters, with 703 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in Crystal, separate from anything a brochure claims.
Zone 6A's requirement is the floor; Crystal's specific load is what tells you whether beating that floor is worth the extra cost.
