I am trying to add insulation to the ceiling of my friends house. Her dad had previously purchased it and it cannot be returned.
The problem is that it has a face on one surface and the house has two previously applied layers. (1980's house) the bottom layer is blown in, the next is non faced and applied by a contractor years ago. I want to lay down this layer paper up. The attic has an almost new exhaust fan to move air through it.
We live in a very temperate climate, western Oregon. Will this layer cause any long term problems.
Thanks-

It will cause so much moisture you will end up ripping ALL of the insulation out. Paper up or down its all wrong and can also create mold and then it gets real expensive down the road

Tear off paper and lay it over the old.

3 months ago I had a customer that did the same thing years ago and it all had to be ripped out

5% of moisture in insul and it looses 95% of its insul properties.

Yep, this is the only fix since you can not have a second vapor barrier. If this is fiber glass with a paper face you will be surprised how easily that face will peel off.

Thanks Much, this isn't what I wanted to hear, but I needed to hear It. I've only put up three rolls and will 'fix' that then tear off the paper and re-roll the balance before installing.
Really appreciate the help!

Thanks for saving me a lot of work and money!

The solution is working wonderfully, I now have another question. Can I insulate over her garage? She has her w/d hookup out there and I think it would be a lot more comfortable year around if I did.

Garage walls and ceiling are fairly easy to insulate. However are you talking about another room above the garage, not certain from your post.
