I'm a bit confused here. In trying to determine the proper way to insulate an old attic I've read that vapor barrier needs to face warm area, down or facing ceiling of lower room...and that you should use unfaced batting in the attics.
This video shows using faced insulation with the barrier being down but the description says to use unfaced insulation.
Here it also says to used unfaced insulation in the attic.
But I have read in several other places that a vapor barrier is needed if one is not present.
The house in question was built in the late 1800's to early 1900's with absolutely NO insulation anywhere. And it does get slightly cold here at times in Mid Georgia. I want to add insulation but I do not want to do it twice. So, the question is:
In an attic installation with no insulation do you use faced or unfaced insulation?
