The asbestos hunt continues, but with a bit more reason and not quite as much worry.
I found this insulation under the floor molding/threshold at the patio door in my old house which was renovated during the 50s, 60s, and 70s.
Hard to get a good picture.
What do you think this type of insulation is?
Glass wool?
White asbestos?
Something else?

it could be asbestos but doesn't have to be.
it is really difficult.
there is some older glass fiber insulation that is really white in color.
if you are really curious, send it for analysis. then you'll get an answer and avoid speculation.

My house is from 1893, but as mentioned, I have no idea when various places were renovated.
Isola, do you think glasullit might have been used locally around skirting boards/thresholds etc.?
Or could it also be in the walls?
Did you investigate and confirm that your insulation was glasullit or did you simply recognize it anyway?
Does anyone know when and how white asbestos, chrysotile, was used as insulation, like loose-fill?
To seal around skirting boards/thresholds etc. or in other ways?
This insulation was indeed available as loose-fill, just like glasull etc., right?
How can you tell the difference between white asbestos and glasull?

Absolutely. Found it used as "drevning" here. Must have been quite itchyStina71 said:
, I've replaced it with linseed calking.Did you look at the pictures? It's a catwalk wall insulated with glasullit; it's even written on the black paper, Höganäs GlasullitStina71 said:
Isola.
Yes, I checked the pictures.
But in my case, it seems more like loose wool, not boards with any paper backing.
When you found drift with glass wool, how did you know it was glass wool?
Because I assume there was no paper with text where you could read what the material was.

Ah, okay. I still believe it's an early form of fiberglass you have found.Stina71 said:
You might be right about thatStina71 said:
But in the wall right next to it was Glasullit, with paper and a nice "Höganäs Glasullit" label. And it had the same texture, itched just as well. So I, being naïve, choose to believe it's the same material.Asbestos, by the way, is not at all a common insulation material in walls. Maybe on ships, but now this is house building.
Glass wool, no doubt about it....
