You are a bit defiant, aren't you? If it is not hazardous waste in the sense of the legislation, it is not a problem to dispose of it later. Whether one still likes it is another matter.
That has nothing to do with defiance, if the legislation suddenly claims that nuclear waste is unproblematic, would you also gladly make your garden available? Great lemmings!
You present your opinion as objective, but you ignore the facts, don't you?
Since 2014/2015, HBCD has no longer been used as a flame retardant in insulation boards.
On the subject of airtightness in new construction: I do think there is a difference whether I have a diffusion-open wall structure or not. In our wall structure, for example, room humidity can diffuse through the inner shell (Poroton) and insulation layer (mineral wool) and then condense on the inside of the clinker shell. At least theoretically. In timber frame houses, I usually see a vapor barrier in between. The question would be how high the SD value of my inner shell is compared to the vapor barrier foil.
That works the same with a wooden stud frame without a vapor barrier...
I never doubted that.
To stick to the personal sensitivities you introduced here: I would build all sorts of things, but never a wooden stud frame. That's because I once rented in one and got to know its "advantages." For me, it's biomass waste. For you, not, of course – so I wish you all the best with it.
Firecrackers, but that is pure theory. Your Poroton wall does not remain bare. There will be gypsum plaster or lime-cement plaster on it. Then possibly putty. Tile adhesive, dispersion paint with primer, which prevents absorbency. Tiles partly. Partly maybe wall wallpapers or fiberglass... it is still completely sealed afterwards. Karsten
