I am researching how to finish one room in my basement, and not sure what to do with what I think is vapor barrier or wall wrap insulation. Its only on two of the four walls which I assume is because those walls are facing the outside. I watched a video that said I should not remove it because its already a r11 value and I would simply measure off 5 1/2 to 6 inches and snap my line. After that im not sure whats next and couldn't find any info. Most DIY sites show rigid foam as the insulation directly glued to the cement walls then furred out for the drywall, which was pretty straight forward. So basically:
- Do I leave the Wall wrap up?
- If I do, is 5 1/2 to 6 inches correct?
- After I frame it do I then use the rigid foam sheets?
- Should I just take it down and do the Rigid Foam?
