  They make insulated garage doors.  Golden rod in your safe is a must.

  Vapor barrier and insulation, and temp control. You need heat in there to keep the air moving
  
  

  It's boring, and your lack of creativity knows no bounds.

  A mini-split heat pump should regulate the temperature nicely.

  Rapid changes in temperature will cause condensation, cold gun in warm run!! So temp control should be your first priority. If you are building a small room it should be easy to heat with a small space heater. I live in Florida, but I lived in Wisconsin before I moved here, and heat and humidity here is more extreme than in Iowa. My shop is my garage. I have a small gun safe to there to keep my works in progress. A Goldenrod in the safe has kept the moisture under control, and I make sure everything is well oiled!! I believe there are stand alone units that can heat and cool and vent outside.
