   tim .. when i have the choice i use cellulose..

   if i'm using fiberglass.. we use friction fit batts , unfaced and a seperate 6 mil poly vapor barrier / air retarder.....
   as you have surmised.. the kraft facing is almost nil in terms of edge barrier...

   I am preparing to insulate ext. walls of a small addition to my house. Walls are 2 x 6 and have lots of windows. I live in Maryland where its hot and humid in Summer and mild and humid in Winter. There are so many small spaces to get insulation into that I am wondering about the effectiveness of kraft faced insulation as a vapor barrier. Would I be better off to install un-faced insulation and use a plastic vapor barrier and tape the seems. It sure seems to me that the later process would be less time consuming as well. Any comments would be greatly appreciated.
