Tiles or vinyl in kitchen and hallway

You make an assumption and presume it to be true because otherwise you would have to question your decision based on this assumption, which has probably already been made. Here vinyl and pollutants.

What is harmful cannot be answered with certainty by anyone.

There are limit values that are adhered to. I read during my research: The coverings for limit value determination are measured at a very/high air exchange rate (I think it was n=1), a certain temperature (
In the bedroom/children's rooms, we therefore do not have vinyl, or only vinyl with the Blue Angel, hard surface, and not based on plastic. Unfortunately, at that time there was no adhesive option available.

By now, there are adhesive design coverings with the Blue Angel and only those would I choose if it is to be vinyl.
