Unknown materials window replacement

[DonCorleone]

Hello!
We have craftsmen replacing windows at our home and there's some material I'm wondering about.
Image 1: Some kind of drev around the old windows
Image 2: Like paper
Image 3: There is dark brown cardboard-like material in the interior walls? The house is from '54
Image 4: Unfortunately, they accidentally cut a power cable that was very close to the window frame. What might the sheath around the electrical cables be made of?

Image 4: Unfortunately, they accidentally cut an electrical cable that was very close to the window frame. What could the casing around the electrical cables be made of?

1 could be flax caulking
2 old building paper
3 looks like tretex
4 hard to see in the picture, but it could be a so-called metal conduit, I think there are both with rubber and tar paper over the cables

Tow of flax. Tarred paper for wind protection. Tretex, soft wood fiber board.

I can't determine from the picture, but really old kulo wiring has a lead sheath, crumbly rubber around the conductors, and a textile sleeve (as I remember it). It's called death kulo because it can easily become live if the sheath is bent on an old cable. Later versions are in metal with PVC insulation that lasts a very long time and can still be safe after 50 years.

Thanks for the quick responses
Thinking more about the cardboard-like layer in this picture. Any theories?

We had similar drives. It didn't smell great, so I tried to remove as much of it as possible.
What kind of fogskum is it?
Check that it is approved for use according to the installation instructions.

What kind of foam sealant is it?
Make sure it is approved for use according to the installation instructions.

I've tried to find out what type of foam sealant it is but can't find anything. I don't know if the color is typical for any particular type. I guess I'll have to check with those who are replacing the window.

Do we have anyone who has seen something similar in a wall? I can't find information anywhere. Cardboard soaked in tar?

Asfaboard might still be available for purchase

 

[MultiMan]

Asfaboard is asphalt-impregnated treetex. This is corrugated cardboard that is tar/asphalt-treated. Never seen it, don't know what it's called.

And yes, it is still sold: https://www.byggmax.se/asfaltsboard-p1002

Edit: Searching the forum exists for a reason: https://www.byggahus.se/forum/threa...a-hem-vill-1949-50.279688/page-2#post-4425396

So: Wellit.
