Hi, I have installed a new interior door from the attic to the kitchen, which seal should I use? There is a significant draft as it's a cold attic, there is 38mm between the wooden wall and the door frame. The house was built in 1948 and the old seal was tow.

I would definitely have continued with lindrev. In my house, I have (so far) only insulated with lindrev, cellulose boards, and wood shavings. I have removed the mineral insulation I found.

Possibly, if there is space, you could complement with a wind barrier on the attic side to prevent drafts through the gaps.
 
You have no experience with Tremco (self-swelling)?
 
Nope. But I don't like fogskum for several reasons. Mostly because I'm conservative. :)
 
It is indeed the case that natural materials are better, especially for old houses. Thank you for the answer.
 
There are certainly those who sneer at such a conclusion, but I am at least of that opinion.

But it must be said that I am not consistent. For example, I don't install new drainage with cast iron, valve shafts with asbestos plates, or iron pipes for tap water. Our bathroom is an example of a major exception to my principles. It has a plastic floor. Plastered walls. I actually have some foam insulation to break thermal bridges in the slanted ceiling. But otherwise, I try to stick to pure materials that haven't had too many substances like glue and binders added.
