If your goal is good panels with minimal harm to health, as was my case, then these panels are what you need. The only drawback is a barely noticeable smell that did not go away even after a month of airing the room, for me this is a problem because I feel smells very well. In any case, this is much better than any panels made of stone wool or something similar. And if you are not sensitive to smells, then the panels are super.
