Behind my sink are two old plasterboards, about 40 cm wide.
They are completely open and visible between the sink and the windowsill.
Not covered by any other material, like a wall panel.
I just noticed these now because I'm in an asbestos paranoia.

I don't need to talk about asbestos and my worry, we've covered that with questions I've asked in other threads, I just simply want to ask:

Does anyone know if there can be asbestos in old plasterboards?
My house is from the late 1800s and has been renovated many times over the years.
So no idea about the age of the boards.

The plasterboard seems to have some form of light beige thin "paper" on both sides.

The picture is unclear and unfortunately, there's quite a bit of dust, old flies, flower petals, and other nice things on top that I can't reach to remove.. :)

Anyone know?

It's not possible to see if it contains asbestos, chip off a piece and send it for analysis to get a correct answer.
 
Now I don't know how long gypsum boards have been manufactured in Sweden, but they were definitely not made in the nineteenth century.
Gypsum boards began to be used here in the 1950s, so what is behind your stove was added during a renovation.
It has likely been refreshed now and then, for example when the stainless steel sink was installed.

But gypsum boards contain no fibers at all, neither asbestos, fiberglass, nor anything else.
(That is why it is so fragile and easily breaks)
Except in certain special cases, when the gypsum is reinforced.
So when it comes to your gypsum boards behind the sink, you can be completely at ease.

Thank you!

KnockOnWood, in which contexts were reinforced plasterboards containing asbestos used? Do these look in any particular way?

And while I'm on the topic again, how about asbestos in chipboard, masonite, other wood fiberboards, Tretex, etc.? I've read and heard that asbestos can be found in, for example, ceiling and wall panels, but nowhere is there a description of what is meant by ceiling/wall panels. Does anyone know? I find this very "vague." What should one go on? What panels should one react to/be cautious with in ceilings and walls? Is it the surface panel being referred to or often some panel with an insulating function inside the wall?
 
Asbestos-containing wall panels are primarily Eternit, a gray asbestos cement board for external wall cladding. As an alternative, Malmex, a lighter asbestos cement board with a lower asbestos content than Eternit, was developed in the 1960s. It was available in pastel colors. For wind barriers on the outside of stud walls, under the panel, there was Internit, an asbestos cellulose board, usually light yellow-gray. Asbestos has only been used when heat-resistant protective material is desired. It seldom or never occurs in interior surfaces, at least not in residential buildings. I have never encountered wood fiber boards with asbestos.

Your obsession with asbestos will drive you insane.........stop thinking so negatively and start living instead.

Otherwise, you could start worrying about everything else too, such as:
Particle board can contain formaldehyde
The ground your house stands on Radon
Concrete of various types Radon
Gravel and crushed stone have quartz dust that is as dangerous as asbestos in terms of cancer
Old oil paint contains lead and zinc
Old leaking refrigerators/freezers freon
Old pressure-treated wood pieces creosote
Sealants PCB
etc etc etc
everything is dangerous in large amounts, but it usually only applies to those exposed to it in such a way that the doses become high. That is, people who work with it daily.

Live, renovate, and instead of dragging yourself down into some imaginary asbestos swamp.

Neither particle boards, tretex, nor masonite contain asbestos. However, particle boards may contain formaldehyde.

Reinforced, but definitely not with asbestos, but with fiberglass.

Just like all boats built in fiberglass reinforced plastic :)

Okay! Thanks again!
I read it as if you wrote they were reinforced with asbestos.
I have also read somewhere else, where builders discussed asbestos, and where they wrote that some gypsum boards could contain it. Hence my question from the beginning.
But, now I have learned that gypsum never contains asbestos. Thanks!

I think it was good that you raised the question about these older drywall sheets! I have some just like that here and there in my house and was quickly able to get some reassuring news. Your asbestos worry is thus beneficial to us others, so I'm very grateful.
For your own sake, try to remember that most people who have worked with the stuff have actually lived to an old age. If a private individual takes reasonable protective measures the only time they are exposed, the risks should be negligible. But again, it's great that you want to ask your questions because if no one did, many of us would remain in uncertainty.
