Hi,
Hope this is the right thread!
We are considering a house from 1953. We need some clarification on the terms below and the respective building materials, as well as general advice on these materials. Concrete is easy to guess, but what is ytong?
Foundation wall: Concrete
Framework: Ytong
Joists: Concrete
Radon measurement: 1989-11-26 - 1990-02-26 = annual average 130Bq
All answers are appreciated. Thank you for the advice and your time!
/Liam
