What zone 4A means for a North Bay Shore window
New York-Newark-Jersey City, NY-NJ runs a January average near 32°F and climbs to about 75°F by July, a swing that adds up to roughly 5,087 heating degree days most winters, with 911 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in North Bay Shore, separate from anything a brochure claims.
Zone 4A's requirement is the floor; North Bay Shore's specific load is what tells you whether beating that floor is worth the extra cost.
