I am redoing my attic(finishing it off) and just insulated my attic with paper faced insultation. Do i need to use a plastic vapor barrier with this or is the paper facing enough of a vapor barrier? Does it hurt to use the plastic with the paper? Thanks for any help with this. almost time to start drywalling the attic!
The paper face is an asphalt-treated paper. It is the vapor barrier.
Do NOT use any other additional vapor barrier. If you do, you will be creating an area (chamber) that will trap moisture.
Making more than one vapor barrier is against building code. If you pulled a permit, you will "flunk" your insulation inspection with more than one vapor barrier.
Thanks Atlantic. That is what i thought i had read but just making sure. The previous owners did so many things wrong. Once again thanks for your time, if your ever in wisconsin let me know, i owe you at least a couple free drinks!
