Help Identify Insulation


Recently started doing some renovations in the bathroom of our home, and came across this insulation in the walls. House was built in the 1920’s, 1923 I believe. It looks like cotton, I looked at it under 20x maginification and it looks fibrous, almost hairlike. Seems to have been blown in as it comes away loose. Could this pose any asbestos threat? From the look, it seems like mineral wool, but I want to be sure.


Looks like Rock Wool


Insulation materials that do not contain asbestos**

Thanks for the info. Any dangers associated this stuff?

That top link I posted is the MSDS document.

Michael, don’t want to butt in, but the is an MSDS (Material Safety Data Sheet)

Marcel :wink:

Thanks for the correction. I knew that. Fat fingers.:roll:

No problem Michael, just don’t want to confuse the recipient, if you know what I mean. :slight_smile:
Daniel Friedman’s information is an elite collection of data.

Marcel :slight_smile: :smiley:

Thanks for the info guys, help put my fears to rest.

Who is he? What kind of data collection does he have? Is it accessible by the general public (meaning me)?

Kenton…try: . That’s where the photo in post #2 came from and is Daniel’s site. You’ll recognize it when you see it.

That is it Kenton; he beat me to it.

Very interesting and full of good information.

Hope you find it useful.
