I have an old house with the balsam wool insulation in the attic. It looks to be double sided with the black facing and about an inch thick (brown inside). I wanted to reinsulate the attic. Can I insulate over this old stuff or should I remove it first and then insulate? If I inulate over it, do I use insulation without the facing?
