Insulation material in house built in 1960

[Eddi Thomason]

Hello

I am in the process of tearing up the floor in a house built in 1960. The floor is the original floor in the living room and is about 25 mm thick and self-supporting. It is just placed on loosely laid joists with wedges underneath to get the right height. After almost 50 years, things have shifted a bit and it creaks quite a lot these days.
I thought I’d be thorough and fix this before laying a new floor.
But, to the question, under the old floor they have insulated down towards the basement with some white wool. We have so far assumed this to be glass wool, but after a friend’s consideration, I became a little doubtful and wondered myself. Could this wool contain asbestos? And if so, are there any identifying features to tell if it does?
I have pictures that I can upload tonight.

Regards,
Niklas

Even if it is asbestos, it doesn't cause any harm there underneath. Leave it be.

As I wrote, the floor is seriously opened up! Kind of too late to say "leave it be"....

Still searching through boxes for the USB cable for the camera, will come back with a picture!

I would guess glass wool, the old variant, that itches and stings incredibly. I have ripped out similar from our 50s bathroom, but with a paper backing. Gloves and a breathing mask are recommended!

I even recommend double gloves for that. Rubber dishwashing gloves or similar, plus a disposable coverall underneath and then a pair of regular gloves on top.

Thanks for the help!

Looks like I can put my asbestos anxiety behind me. I'm not going to tear out or even touch the insulation at all. But unfortunately, I will have to insert some extra support for the floating floor joists, but I'll do that carefully and with gloves on.
Then the lid goes on for good
