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?
