What zone 5A means for a Glocester window
Providence-Warwick, RI-MA runs a January average near 27°F and climbs to about 71°F by July, a swing that adds up to roughly 6,275 heating degree days most winters, with 509 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in Glocester, separate from anything a brochure claims.
Zone 5A's requirement is the floor; Glocester's specific load is what tells you whether beating that floor is worth the extra cost.
