Five Corners sits in IECC climate zone 4C, which sets the energy-performance bar here no matter who ends up installing your windows. A window license file doesn't cover Five Corners on this site, so Google Maps supplies the 10 ranked names you see below. Checked October 2026.

What zone 4C means for a Five Corners window
Portland-Vancouver-Hillsboro, OR-WA runs a January average near 39°F and climbs to about 65°F by July, a swing that adds up to roughly 5,295 heating degree days most winters, with 192 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in Five Corners, separate from anything a brochure claims.
Zone 4C's requirement is the floor; Five Corners's specific load is what tells you whether beating that floor is worth the extra cost.
