Material in the ceiling?

[Stina71]

Anyone know what this material is? The panels were used as a dropped ceiling in an old house and below them was some kind of tension paper. In the pictures, you can see both the paper and the panels. The panels are about 1 cm thick, or something like that.

Of course, I'll ask my "standard question". Does anyone know if this material can contain asbestos?

I'm not paranoid, no, spare me that kind of comment, thank you. I just want to know since we've created a lot of dust when these ceilings were torn down.

Thanks in advance!

It looks like a tretex board. No asbestos in these.

It is a board, type masonite or similar. Does not contain asbestos.

I would have guessed masonit (board), that's not dangerous either. But it's a bit hard to see, are they soft and light or heavy and hard?

Edit: Second to the ball

Masonite boards and the cardboard are regular paper. No asbestos in any of it.
