I live in 50+ year old house. My walls insulation is black one. I don't know what it is it does not look like fiberglass. The insulation is very loose and torn. I am currently installing new windows enlarging the openings. I thought about ripping off old sheetrock on outer walls, adding R-13 faced fiberglass insulation and then putting new sheetrock. I am worried about asbestos in old insulation and sheetrock. How can I figure out if they contain asbestos and may be dangerous to be disturbed? What else besides vinyl tile may contain asbestos in old house?
