I have started to dig around a bit in my hallway and have noted that there are tretex boards on all the outer walls there. Behind these is beadboard paneling, something I would like to bring out. But how much insulation does the tretex that is there now provide? There is probably not much insulation otherwise in the wall :-/
Do you think it will become extremely cold if you take down the tretex boards?

Actually, I can't answer your question... I asked the same question 6 months ago, but then about tretex in a stone house...
We hesitated for a long time about whether to leave the tretex in place or to take it down and do the work of replastering the walls... and started by letting it stay, but then switched to taking it down...
Tretex insulates a little if there's no other insulation...
I suppose you wouldn't find it easy to take down the tretex and also carefully remove the paneling, then insulate the wall normally and then reinstall the paneling...
Best regards,

if I remember correctly, tretex insulates like three 13mm plasterboards...
but plaster is 1000 times more enjoyable to work with wallpaper and paint on (and if you don't want to change moldings and junk against windows and doors, the choice is quite simple
)

The Tretex is on exterior walls in a stairwell/hallway.
In other words, will it become cold if I tear down the Tretex?
The exterior wall is constructed like this, I believe:
Facade brick -> Panel -> Windproof paper -> Standing tongue and groove wood -> Beadboard and innermost Tretex which I now want to remove
It is not foolish to keep the tretex boards in place. Tretex is a breathable material made from wood fiber paper. It's a technique that's been used for a long time, and at one point all tretex was supposed to be replaced because rockwool and other insulation were sooo much better. Tretex insulates about as much as regular 45mm insulation. So removing it will make a noticeable difference in the warmth of your stairwell, I believe. Additionally, it acts as a wind barrier just like wind paper. Many of the old things would still be better used and they work very well, but it's the allure of novelty that sometimes dictates bringing in the new. As long as it's dry around the tretex, there's no reason to remove it. It's a shame, though, about the paneling behind it. But if you need to re-insulate because you remove the boards, the question is, can you remove the paneling intact? It’s a dilemma for the conscience, whether to do it or not..=) Hope this gave you some info

We have removed ours. But we have added insulation on the outside.
A drawback, as we saw it, with tretex is that it's apparently quite flammable. But if you put gypsum on top, it might not be a problem.
We thought it felt good to remove it and replace it with gypsum.

Tretex is the best! Soak with diesel and light the stove with it, it burns for a long time and lights super
Seriously, I don't think it's much more flammable than bone-dry wood, that's how I experience my tretex at least (and I've tested it in the stove).
If it burns in an old wooden house, it's probably almost a lost cause right away, regardless of tretex or not. In 5 minutes, the house burns as if it were made of gasoline.

The only advantage I see with Tretex is that it's easy to trace in... i.e., make channels for electrical conduits, junction boxes, etc. Then put a sheet of drywall or chipboard on top... Tretex was really in an intermediate stage of building technology, before chipboard became cheap enough that people embraced it... Personally, I'm not a fan of Tretex, but it can be good in a children's room. Put a sheet on a wall... tell the little one that on this wall, you can do whatever you want... >Usually works well....
I would like to see a reference that a treetex board of 15(?)mm insulates as well as a 45 mm regular board of stone wool or glass wool.
Since it is so incredibly unlikely, I consider the information to be an incorrect guess until it is substantiated.

Yes, it sounds like a fairytale. I don't want to disappoint you, but it's true. Treetex is an amazing board but has undeservedly gotten a reputation that downgrades it. I believe people generally have a hard time understanding the difference between Treetex and masonite. (By the way, these names are trademarks). Treetex is a porous board and masonite is a hard board. Older Treetex boards were ½ inch thick, 12.7 mm, because the machines were American. (The production was an American invention).mattiasp said:
The lambda value for a 12.7 mm thick Treetex is 0.036, which corresponds to 46 mm of solid wood. To quote Paroc: "Thermal conductivity
Paroc stone wool products have low thermal conductivity (lambda value). Compared to wood studs, the difference is 3.8 times. This means that an exterior wall of solid wood must be 4 times as thick as a wall insulated with stone wool to achieve the same insulating value. With today's increased demands for reduced energy use, this is unrealistic. More cost- and energy-efficient is to combine wood studs with
between or outer-layer stone wool to reduce wall thickness. Paroc has products for walls with declared thermal conductivity λD that varies between 0.034 and 0.037 W/m²°C." If I haven't misunderstood this, it means that Treetex insulates as much as stone wool at the same thickness. I will also refer to this page: http://www.byggahus.se/forum/byggnadsvard/105500-treetex-foerdelar-och-nackdelar.html and also Paroc's page: http://www.stenull.paroc.se/produktdat/pdf_down/Vaggkonstruktioner.pdf
What conclusions can be drawn from this? Yes, Treetex insulates very well. It is also environmentally friendly. A pure natural product entirely made of wood. Another very big advantage is that it doesn't need to be packaged together with plastic. It breathes, together with the house it dresses. Yes, I hope this was helpful. Looking forward to feedback.
