Hi All,
I looking to add encased fiberglass batt insulation in my attic over
existing fiberglass insulation. The existing insulation has kraft
paper on the ceiling side. My question is will the encased insulation
act as an additional vapor barrier that will cause problems?

Thanks in advance for your help.


I called the company on this very issue. The brand I used (dont
remember now) was encased but perforated somewhat. The manufacter said
put it over existing as you have.
