I removed insulation from two T-joints on the heating pipes, just wondering if it's asbestos or not.
I know the yellow isn't asbestos. There wasn't really any dust or powder, but is there asbestos in the white outer layer?
Then by chance, I found a small roll of fabric, I assume it's for heating pipes, is there asbestos in it?
I can't comment on the weave, but the white paint is apparently sometimes able to contain asbestos (which was added to make the paint "drip-free"). Impossible to know without sending in a sample (or examining with your own microscope). It looks the same in my house, but I haven't had to tear it down yet.
