We are finishing our attic and have already put up the paper faced insulationWe have now been advised by a friend who is a contractor that we need to add a plastic vapor barrierIve asked around and some people say that the paper faced insulation is enough and that a vapor barrier will actually cause mold instead of preventing itI also read on the internet that the plastic vapor barrier will stop the warm air in the room from meeting with the cold air in the wall cavity therefore preventing condensationDoes anyone else have any input on what to do? We are at a standstill with the project until we decide! But we dont want to make a mistake and regret it laterPLEASE HELP!!!
Most older homes have enough air leaking in and out that a vapor barrier is not as important as it is in a new, tightly-constructed homeIf you add a vapor barrier, do not try to pull back the insulation and install plastic between the ceiling joistsIt's better to use a vapor barrier paintVapor barrier (more accurately called vapor retarder) paints are available from paint companiesThese paints are formulated to stop water vapor from moving through the wallTo be effective, they must be applied according to directionsThis means putting on a thick coatIt is probably safest to put on two coats to assure enough thickness.
