Has anyone tried acoustic grooved chipboard underfloor heating like the Onmie TorFloor RdB? I am interested in installing it as a retrofit in an upstairs en-suite. It is for a retrofit in a newish house with web joists so I presume there will be space to fit all the piping. I am keen to reduce sound transmission from upstairs to downstairs and thus I am interested in this acoustic option. I am a bit sceptical though. The idea that it replaces the sub floor is appealing as I want to lose as little height as possible but will it result in a creaky floor? How can a series of panels not leak sound to below, even if they have mass loaded vinyl, given all the joints? I guess it is only reduce impact sounds rather than eliminate all sound? I guess such an underfloor heating won’t provide massive amounts if heat?
