Insulating and existing building

MuzzyRidge | Posted in Energy Efficiency and Durability on

I have an existing building located in Maine that was never insulated. The exterior is completed. The interior has no finish. Since I don’t have the option of insulating over the exterior, I would like to know what my best options are for insulating from the inside. The framing is 2×6. The attic space has gable vents. 
Thank you, Paul

    What's the intended purpose of this building? Home? Cottage? Garage?

    When you say the interior has "no finish" does this mean no sheetrock on the wall - just open studs?

      My thought at this point was to use rockwool in the stud bays and then going over the inside of the stud surface with 1 in rockwool sheets. I was then thinking of using a smart vapor barrier. It's a two floor building with about 700 square feet per floor with a large percentage of window space.

    Yes, open studs
