An above grade portion (wood framing) of my basement walls (in unfinished furnace room) is currently insulated with faced R19 fiberglass batts . It is very drafty because the batts dont fit perfectly and the wall is not air sealed behind the insulation. I also understand that it is supposed to be covered with drywall to prevent combustion.
I am undertaking a diy project to correctly air seal it and reinsulate it. The approach i have in mind is to glue rigid foam board to the wall, and use great stuff to fill around it. Then i want to reapply the fiberglass on top of the foam board.
I have read that the paper should be removed to prevent a double vapor barrier since the foam board will be air sealed up against the wall. Is it ok /necessary to remove the paper from the fiberglass batts and leave it exposed in the furnace room after doing the air sealing as above? Does this present a hazard? Is it better to replace the fiberglass insulation with something else assuming i dont want to drywall my furnace room?
