Planning on re-insulating my rim joists tomorrow (well, later today, I'm up late.)
I've only removed one of the old pieces batt-type insulation. Home was built in 1958.
No idea when these batt pieces were put in. No markings on the insulation.
Could these have asbestos in them? Do I need to have them tested before I remove them all, or am I definitely in the clear?
[Yes, I know the only way to know for sure is to have it tested. Just looking for opinions from people that take asbestos seriously but not beyond overboard to the point where they're spending lots of money testing stuff that shouldn't have it in it.]
(BTW I know the tile in the pic likely has asbestos.)
(This one I'm holding upright, to show how thick/thin it is)
