Hi Ilona

Thanks for your best wishes. I'm amazed and delighted to have got this far in the competition.

A BaleHaus floor is made of solid, cross laminated timber, which acts as the structural slab. it is 120 mm thick and does not need to be any thicker. What the video does not show is that we then put on top of this 100 mm of wood fibre insulation, into which an underfloor heating system can be installed and then on top of that we put a timber floor finish. This gives us the acoustic performance you identify as being needed and a low energy heating system. It also looks good.

You can see a gallery of photos of the just completed BaleHaus at Bath showing the finished flooring.

I hope this answers your question.

Regards

Craig
