(1) Should I add a vapor barrier. I don't see any moisture problems in my attic and the house is 17 years old. My soffits are all vented properly.
(2) If yes (add vapor barrier) should I use plastic sheeting or just use the faced insulation. I know that I have to put the vapor barrier under the blown in insulation. The extra work doesn't bother me. My concern is that the plastic sheeting in not going to be the best solution because I got to work around all of the wires and pipes that already exist in the attic. So it won't be continous.
(3) Does anyone have experience with radiant barrier chips? I have been told just to add them instead of the insulation.
Any comments would be great.
