| Comment | Can for sure remove it if they replace it with something better. Properly replacing it with a good airtight seal, rockwool, nice tight thermafleece insulation, a vapour layer, and then a properly fitted floor, will be 1000X times better than the ash that is is there. It will insulate the sound and the heat much better. The issue is it is costly to do this properly and a lot of folks vacuum out the ash and they throw down a strip thermafleece and call it a day. Then they marvel that their neighbours can hear every step they take.
The modern methods of insulating and sound dampening are much better than the old ash so OP can remove it if he is going to replace it properly with something better. |
