Risk of Asbestos in Houses from the 60s?

[Tååmten]

Hello
I hope this lands in the right category or that someone can point me in the right direction.

I have a Hultsfred house from the late 60s and have some renovations planned.
I'm wondering what risks there might be that materials containing asbestos were used in the house.

Basement of concrete, of course.
Wooden beams between the basement and the main floor with sawdust as insulation material except in the bathroom where there was fiberglass insulation around pipes. There's also insulation around some of the pipes running under the basement ceiling.
Fiberboard in all walls with chipboard and Masonite panels.
Between the interior ceiling and the attic, there are wooden beams with insulation primarily of fiberglass, if I've seen correctly.
There's a chimney running from the basement.
Some form of fiberglass insulation around the windows.
That's as far as I've been able to see.

Should I involve a company to investigate, or can I assume that there is or isn't any risk?
I've also tried to find good information about what materials from that era might be suspected to contain asbestos, but haven't come up with anything clear, so information about that is also interesting.

Thanks in advance.
Magnus

Pay attention to plastic flooring of all kinds. There may be asbestos in both the flooring itself and in the adhesive.

Asbestos was also used where insulation with good resistance to very high temperatures was required, e.g., in wood-oil boilers, around chimney pipes. In other places, cheaper glass wool was used as insulation.

The obvious possible sources are likely pipe insulation (the bends). Tile adhesive in the bathroom. Black glue under the plastic mat. Asbestos cement channels in the ventilation may exist.

Thanks for the tips, I'll keep an eye on it.
Ventilation ducts are scarce and I don't think I need to do anything with them.
There are plastic mats in the basement and they need to be removed, so I'll check a bit more carefully.
No boilers that are connected to the chimney, but they might still be present in the blocked ducts.
I'll contact a cleaning company when the time comes.
If anyone comes up with anything else, I'm happy to listen.

Window putty.

What do you mean by "fiberplank"?

If there is a boiler room in the basement, there may very well be asbestos boards in the ceiling, etc. as fire protection.

You investigate yourself by taking samples and sending them for analysis.

May also be found in window sills made of asbestos cement. Can be visible on the underside (we have such).

A building material used by Hultsfredshus. Consists of soft fiber board between two studs that are installed upright. Search for the word and you will find it.

Okay,
Some form of early prefab then. I was wondering what it was when you mentioned fiber in connection with asbestos since there are asbestos-containing fiber cement boards.

No, it is a pure wood material as far as I understand. Good insulation values. Must have been convenient to build with.
