Floor coverings free from harmful substances

I assume that metal as a floor covering is not desired now.

Choose a nice flooring that you like (I personally always go for parquet, oiled/waxed). Plastic like laminate or vinyl goes into the affordable rental apartment, but not into the owner-occupied home.

P.S. Parquet should always be glued on underfloor heating. That also works with click parquet. And there are plenty of extremely low-emission parquet adhesives for that. Doing it yourself is no witchcraft and saves a lot of money.

Dear forum, we are considering which floor coverings we want in our new prefabricated house, it is important to me that no harmful substances are contained (formaldehyde, VOC, permethrin, etc.). We plan tiles for the bathroom, kitchen, and hallway. For the living area, bedroom, and children's rooms, however, we want a warmer covering, preferably in wood look. I do not want carpet and cork is probably ruled out because it is too sensitive to light and pressure for us. I have already read a lot on the internet, where cork, linoleum, bio-floors and parquet or wooden floorboards are often mentioned as particularly low in harmful substances. However, it is also pointed out that it often depends on details, e.g. clicked or glued (formaldehyde risk), whether the top layer has a coating that is contaminated with harmful substances or whether the carrier board contains toxins... that all makes sense. It is also written that seals, like the Blue Angel, do not guarantee freedom from harmful substances but merely that the harmful substances are below the legal limit. Some posts also say that the load from materials installed in the room adds up, e.g., if the wall paint is just below the limit. That simply annoys me, what can I rely on if even certifications are questioned. I am now wondering how to get a floor that contains NO harmful substances. Of course, price plays a role, our prefabricated house provider offers parquet for €140 including installation, that is the upper limit. We could also install a click system ourselves and save money. Is that possible with underfloor heating? Does anyone know a brand (e.g. for laminate, engineered parquet, parquet, bio-floor, linoleum...) or have a tip for meaningful seals? How do you assess the "bio-floors," where they often speak of reduced harmful substances? The contained polyurethane is said to be critical as well. Best regards

At home, the "poor little ones" have to play on laminate :p

Similarly, falling toys may cause a small dent that matches wood better than a cracked tile.
