my wife and I bought a house in Long Island, NY. The house was built in 1962. In the attic there was about 2 inches of insulation. The paper on the insulation, which was facing toward the roof, has completely disingrated. I place R-19, without paper, on top of this insulation,filling the spaces between the beam. My question is can I add more insulation? I believe I can add more r-19 without the paper and place it perpendicular. I just do not want to create a moisture problem.
