As such, I would not have an option of burying the ducts in blown-in insulation. As Beforehand stated, it does have a skinny layer of insulation and an outer plastic wrap created round the ducts.

5'' of XPS bewteen a 2x4 rafter Place that will likely serve as air flow cavity in a cathedral/slant wall of the a person and 50 % Tale house. What need to the internal most board be XPS or perhaps the ISO.
