The short answer
In Minnesota, the main cost factors for a garage door are its insulation level and construction, along with which of the state's two IECC climate zones (6 or 7) a home sits in; Minnesota also applies its own amended version of the model residential energy code.
This page explains what drives the cost. It does not quote prices: no verified local price data has been published for this area, and every door is different.

Minnesota's Residential Energy Code
Minnesota adopts the residential provisions of the 2012 International Energy Conservation Code with its own amendments (Minnesota Rules chapter 1322) rather than using it unchanged, including an amended insulation and fenestration table for the state's climate zones 6 and 7. How those envelope requirements bear on a garage door depends on the project, so it's worth confirming with the installer when building or replacing a door on a conditioned, attached garage.
Climate Zone
Most Minnesota counties fall in IECC climate zone 6, while a band of northern counties, including St. Louis County and the Iron Range, sits in the colder zone 7. Homes in zone 7 more often justify a higher R-value door for comfort through the region's harsher winters.
Door Construction and Panel Type
Steel gauge, the foam core type, and weatherstrip quality all affect both upfront cost and how the door performs through a Minnesota winter.
Cost factors
- State energy code amendments
- Minnesota applies the 2012 IECC residential provisions with its own amendments, including an amended insulation and fenestration table for climate zones 6 and 7.
- Climate zone
- Most Minnesota counties are in IECC climate zone 6, while northern counties including St. Louis County are in the colder zone 7.
- Panel construction and core material
- Steel gauge and foam core type (polyurethane vs. polystyrene) both affect R-value and price.
- Door size and number of sections
- Wider two- and three-car doors and doors with more sections generally cost more than a single-car door of the same construction.
