Yes i m' reflecting about that, i was inspired by studio of Branko in Portugal. New rooms in Portugal
They used 10 cm of Rockwhool but it's was only for the floating floor.
And there build they envisaged Rockwhool will be crushed of 3 cm.
But in my build i think that will be to mutch weight for Rockwool.
So, i'm thinking to use small square of sylomer like 5cm x 5cm with spaces of 20 cm between each peace and make a big checkerwork and to put formwork on it.
If you have any advise they are welcome.
For the height of the celling and issue with the increases of the floor.
Because we are on the ground, we can dig 20 cm in the ground to compensate, so we will keep the same height than before.
