Dear forum,
thank you in advance for your assessment!
About eight years ago, we completely renovated a beautiful house (built in 1962) in a small town. The house was more than a stroke of luck; we were already impressed during the first viewing by the structure, the location, the huge plot of land, and the beautiful old oak parquet flooring that was installed throughout the whole house (including the kitchen). The renovation went well; we ourselves come from the region and had many advisors, whether in our circle of friends or family, who supported us.
Even back then, I kept an eye on hazardous materials, understandable given the year the house was built. Of course, the usual suspects were found (e.g., Eternit on the lean-to roof); the respective specialist companies removed these properly. However, there was one thing I ignored, but it hasn’t quite left my mind; otherwise, I wouldn’t be here.
The parquet is laid on battens, and under these battens is basalt wool. I know this because I still have the invoice from 1962; basalt wool is explicitly mentioned there. I spoke with my parquet installer when he replaced some slats—he just looked at me completely incredulous: That’s just Rockwool, what’s the problem? We wanted to keep the floors, so the wool is still there where it has been for 60 years. Of course, the floor is anything but airtight. During the winter months, gaps open due to the heating period, so dust certainly escapes; that much is certain. A proper risk assessment is difficult for me. I, of course, know about the KMF issue, but I don’t know whether the problem justifies a subsequent disposal. Fixing the problem would mean removing 140 sqm of parquet during an ongoing daily life with family and children under safe conditions—a thought that naturally does not please me.
I would be happy if an experienced parquet installer could give me an assessment; I fear that should be daily business. Any assessment brings us closer to a solution.
Thank you and have a nice weekend
