"That IS an interesting link Brian!  I've seen a straw version of that material:  Hey Rem, 2,000,000,000 BTU annual load?  What "small house" are you thinking?   Most houses I've seen have 500-1800…"

"At least you know now.  So many materials contain asbestos its probably more difficult to say it doesn't than it does.  Good luck."

Paul Bowman replied to Paul Bowman's discussion Unknown Old Insulation
"We had a sample of the insulation lab-tested, and the result was a negative without qualification — no asbestos found. This is only one case, of course. For all I know, some of the product was made with asbestos and some wasn't. But it…"

"Many thanks to all for suggestions here. Over at InspectionNews someone else offered the name "Balsam Wool" — and with a little further digging online, that led me to what I now think is the actual answer, an old Kimberly-Clark…"

"Expanding on the "humid area" question - do you think the material has gone through numerous wet/dry cycles?  Looks like it's turned to dried oatmeal in the pictures"

Bob Kretvix replied to Paul Bowman's discussion Unknown Old Insulation
"All I can say is that if it isn't known and has the appearance of something that could contain asbestos (i.e., not clearly fiberglass or mineral wool, etc), OSHA requires that it be PRESUMED to contain asbestos and treated as such until negated…"

"It appears to be mineral wool, but it could also be an old Balsam Wool (wood-fiber) batt. Neither would contain asbestos."

Robert Meeker replied to Paul Bowman's discussion Unknown Old Insulation
"It looks like some insulation I encountered on some ducting installed in the 1960s. I had it tested for asbestos and the results came back as just being all cellulose."

"Never saw this, but looks a little like air-cell pipe insulation. This is considered Presumed Asbestos Containing Material.  You should have it tested by an accredited Asbestos Inspector before doing anything to disturb it. "
