Covering asbestos tile in basement
I live in a 1948 brick home with a basement. We are in the process of re-finishing half of the basement. Upon removing the carpet we discovered (likely) asbestos tile. It is not in good condition but mostly well-adhered. Consequently, we’d like to leave it and cover it. We are wondering the best way to do that. We are open to flooring options. On the walls, we are planning to insulate with rigid foam (Thanks for all the detailed responses on the forum. I have read, and learned a lot.) but we are stuck on what to do with the floor.
My thought was to insulate with 1″ foam on the floor, followed by 1/2″ ply wood (we live in DC, so this seems like an ok R-value?). However, the head space is low and every inch matters. So we are wondering if we can cover the asbestos with concrete leveler instead and avoid insulating the floor. From other forums, my gut tells me that we will have a temperature differential issue which could lead to higher humidity, particularly in the summer.
In the forums I haven’t seen guidance for insulating on top of tile. Am I missing something here? How would you finish the floor in our situation?
