Im redoing my porch and now have access to insulate the floor of my upstairs that hangs over.
If i pull the insulation thats there now i can see right in to the inside ceiling.
Should i block that off and air seal each bay then fill with roxel? Or should i just cover entire area in 2" tuff r dow board and seal all the seams?![Cantilever insulating Cantilever insulating](https://www.hearth.com/talk/data/attachments/182/182370-3b4e6f7dc823f67e2a0736769dd905f3.jpg)
