Adding attic Insulation
Good Morning: I am a 1st timer with a question about attic Insulation. I have recently purchased an older house with 6" of fiberglass insulation bats in between the joists. This insulation is covered with pine floor boards that have gaps between each board.
Question - I want to add another layer of insulation(12")over the top, will the boards act as a vapor barrier of a sort and do I need to take up the flooring? After adding the insulation, I have no intention to used the attic for storage. In addition to the added insulation, I have already added a foam stair cover (purchased from HD)to cut down on heat loss from below and vapor penetration - there was some frost build up on the roofing nails and condensation on the plywood. Many Thanks,
