Is this wood wool? Or other insulation?

[Eriklof]

Hello!
I am in the process of replacing the ceiling in an older house, built around 1900. It has been renovated several times over the years. I found this grayish insulation, tried googling, and it seems to resemble träullit. But I am unsure, does anyone know?

Sincerely,
Erik

That's it.

Wood wool is crap, you can't attach anything to it. It's not uncommon for it to be laid first and then cast on top, if there's concrete above, so trying to remove everything is probably out of the question. How thick is it? You can attach a joist to the concrete above with long screws, which the new ceiling can be attached to.

Träullit is crap, can't attach anything to it. Not uncommon that it was laid first and then cast on top, if there's concrete above, trying to remove everything is probably out of the question. How thick is it, is it possible to attach a beam to the concrete above with long screws, which the new ceiling can be attached to.

There was an old frame for the woven ceiling that I attached the beams to (träullit behind the insulation visible in the picture).
Thanks for the advice!

Looks good, as well as space for electrical wiring between the studs.
