We are at the insulation stage of our new home. Fairly large home with cathedral ceilings. We have chosen the blown insulation for the majority of our home and the question arose regarding the use of a vapor barrier for the blown insulation. I know the ole plastic trick has been famous for years but is the same true for blown. I am hearing so many sides both pro and con and I am officially confused. Any assistance is appreciated.
I was all over the web and talked with local vendors and contractors and just could not find any consistency to the answer. Does any one really know or is this just a guess?
Appreciate any help and have a great holiday season everyone.
