Does that floor (ceiling) insulation paperback need to be removed or cut open?
I already scanned through the previous 12 months of questions. Didn’t locate obvious answers.” Answer: 1) The two long walls should be insulated just like any exterior wall. We recommend Kraft paper facing rather than any plastic since the vapor retarder will be in a high moisture content area. 2) Building out is your discretion. Building out will let you increase the R-Value of the wall but keep in mind it will also reduce the living space in the room. 3) No. You will still benefit from the acoustic value between the floors. 4) No. Keep in mind that if you are finishing the basement you will need proper air handling or a dehumidifier to prevent moisture problems.
