Hello, the interior walls of our house are covered with a type of board that "crumbles" when you tear it down. I wonder if anyone knows what this material is called? The house was built in 1974. We have had problems with odors from the building materials for a long time and have, among other things, replaced the subfloors in all the bedrooms as they were leveled with casein-containing smoothing compounds that emitted ammonia, resulting in respiratory issues. The indoor climate is significantly better now. I imagine (?) that these wall boards also smell a bit "sharp" and "dry." Could it be that these also contain some substance that causes "emission"? Anyone with similar experiences? In one room we have covered with renovation gypsum, and it smells a bit fresher there. But perhaps they need to be completely torn out?
If it is masonite, it seems to be okay? Quoted from the web about masonite; "From an environmental standpoint, masonite is a good choice as it does not emit any unhealthy substances. To renovate the existing material instead of replacing it is also both resource-efficient and economical. From a technical perspective, masonite has good strength. A masonite wall, unlike a drywall, can hold things with regular wood screws and you don't break through it without using very heavy tools.
Build board it sounds like, it is 9 mm thick, not wood behind it and not particularly porous. Actually works well to attach to. But as mentioned, doesn't smell completely good. You could say "old".

As mentioned, it's not tretex but building board, meaning some form of masonite? We think it smells a bit "sharp," maybe a bit old? Definitely not mold, but still not "good." We're considering putting renovation plaster on top, but maybe it's silly to build it in? The smell should decrease with plaster on top, right? It's a nightmare to tear down the boards...but maybe it's best?
Had the same panels in my house, smelled "musty" like an old basement almost. It's the material that is old and smells "old." I threw out most of it, but in some places, I put plasterboard right over it. The smell is gone in my place, but common sense tells me I've just encapsulated it behind the plasterboard - might seep through later
In any case, you don't need to worry that it's mold or anything. Just old materials that smell old
EDIT: I would have torn down the stuff and put proper plasterboard on the walls, it improves fire safety IMMENSELY too! The wood burns like tinder!
