I live in MN. The code is R-19 in the walls. Some have indicated that to have geothermal the walls should be insultated with nothing less than spread foam, or better, build with ICF. Upgrading to spread foam insulation is twice the cost of R-19, which takes lot longer to get your return on investment which no one seems to be factoring in.

The type of insulation is not as significant as the air seal.

  • You live in MN, so you know how well a good ski jacket can perform.
  • But you will still freeze...
