What zone 4A means for a Salisbury window
Salisbury, MD runs a January average near 38°F and climbs to about 79°F by July, a swing that adds up to roughly 3,764 heating degree days most winters, with 1,499 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in Salisbury, separate from anything a brochure claims.
Zone 4A's requirement is the floor; Salisbury's specific load is what tells you whether beating that floor is worth the extra cost.

Storm and weather risk around Salisbury

Neither rating changes a window's energy label, but both are exactly what impact-resistance and design-pressure ratings are built to answer for a Salisbury home.
Ask specifically about design pressure and impact rating for Salisbury, not just energy performance, if either risk rating comes back on the high side.
