Plymouth's Climate Data and Its Top-Rated Window Pros
ENERGY STAR groups Hennepin County into its Northern zone, the U-factor and SHGC target worth checking against any quote you get in Plymouth. Below that spec discussion sit 10 installers, their order set by Google rating, since Plymouth is outside this site's window license file. A high rating is worth a look, not a finished decision.

What zone 6A means for a Plymouth window
Minneapolis-St. Paul-Bloomington, MN-WI runs a January average near 15°F and climbs to about 73°F by July, a swing that adds up to roughly 7,683 heating degree days most winters, with 671 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in Plymouth, separate from anything a brochure claims.
Zone 6A's requirement is the floor; Plymouth's specific load is what tells you whether beating that floor is worth the extra cost.

Ask specifically about design pressure and impact rating for Plymouth, not just energy performance, if either risk rating comes back on the high side.

The order below weighs a Google rating against its review count, the same way this site weighs a U-factor against a brochure claim: on the number, not the name. Treat it as a rating, never as proof of a license, bond or HVHZ approval.
