What is that gray board in the wall?

[Pior]

Can someone tell what this gray disc is?

The disc is located in the middle of the wall of a garage built in 1975 with a facade in mexitegel. The picture is taken in a ventilation hole. Could it be something with asbestos?

Thanks!

Yes. It is almost certainly asbestos.

Is it hard or soft? Almost looks like blekt asfaboard.

Similar to the boards we have behind the wooden paneling on our house built in '76. It's some kind of asphalt board. Asbestos was mainly used in pipe insulation, carpets/adhesive and in other places where heat resistance and/or durability were needed, not in insulation in garages.

It is hard, can't break it with bare hands at least.

Thanks, that sounds promising!

Yes. It is almost certain that it is asbestos

Oh dear, why do you think that?

How thick are they?
Reminds me of eternit

 

[öringen]

reminds of eternit, like the panels that are often used as ceilings in boiler rooms. Could it be that the panels are the original interior wall covering and that they have later been framed and insulated? It was common to use eternit panels as fire protection in boiler rooms, garages, and similar spaces.

Reminds me of asbestos cement

About 5mm. I agree that it unfortunately reminds me of asbestos cement

 

[Pior]

reminds of asbestos cement, like the sheets that are usually used as ceiling panels in boiler rooms. Could it be that the sheets are the original interior wall cladding and that later it has been framed and insulated? Asbestos cement sheets were commonly used as fire protection in boiler rooms, garages, and similar spaces.

Unfortunately, that sounds plausible. Should anything be done about it? Risks?

Start by investigating if it is actually asbestos. You can take material samples and send them to a company (Google it, there are many) that can determine if there are asbestos fibers in the board.
Then you have better information to decide what to do. Even if it is asbestos, no fibers are released as long as the board is not processed, but it might be good to remove it if you are going to do something anyway.

 

[Demmpa]

As long as no one processes (e.g., breaks) the fiber cement, it is harmless. No asbestos fibers are released if left undisturbed. However, it may be a good idea to somehow, for the future, mark that there is fiber cement in the walls.

Recognize that construction from a house built in 1970, brick, air gap, this fiberboard, and then the frame as usual. Presumably, it was used for what is now used as wind barrier or asphalt board. That is, to make the house reasonably windproof but so that any moisture can escape from the underlying wall. Reminds a lot of facade/roof panels of asbestos. So, avoid cutting/drilling into them. As long as no one touches them, they pose no health risk. If you need to do so, take necessary precautions and avoid creating dust.

Might be some type of fiber cement without asbestos as well, hard to say.
