I recently have moved into a house that was built in 1929. The attic is insulated by some sort of insulation that looks like someone was shearing a sheep up there. I suffer from really bad anxiety and of course all I keep thinking now is whether or not this wooly substance is asbestos?

I don't want to get something tested if it isn't remotely close to something I need to worry about. I had a home inspection and the inspector looked at it and didn't seem overly concerned.

The stuff is grey and very fibrey(?). Not sure what to look for to tip me off if I need to get this tested or not. Anyone with any experience please let me know.

The material you describe is mineral wool or rock wool. It is a manmade fiber that preceeded the manufacture of fiberglass insulations. It is not associated with chronic disease, but can cause temporary respiratory irritation when disturbed causing dusts (same as fiberglass). Asbestos was fairly expensive and too expensive to be used as a home insulation. There is an FAQ for mineral wool at this address:

Thanks for the speedy reply.

So I guess I really shouldn't be too worried about it containing asbestos then. That's quite a relief, since all of the info on asbestos says get it tested, but you can spend a ton of money testing everything since they're not specific on what to look for.

My thanks again.

What you are seeing might be woolrock or just plain blown cellulose.

Neither is toxic to humans.
