Is this insulation?
I inspected a house yesterday that had a type of insulation that I have not seen before. It looked like cotton batting in long, tubes of thin perforated red plastic. The material was all white, relatively fine, not coarse like normal fiberglass insulation, and the tubes were laid between the joists. The photo shows some of the insulation that was stuffed in place above the attic access stairs. Any idea what this is? Thanks!
