Puyallup's climate zone, in plain terms
Seattle-Tacoma-Bellevue, WA runs a January average near 40°F and climbs to about 64°F by July, a swing that adds up to roughly 5,397 heating degree days most winters, with 120 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in Puyallup, separate from anything a brochure claims.
Zone 4C's requirement is the floor; Puyallup's specific load is what tells you whether beating that floor is worth the extra cost.
