I calculated the weight of my room would be around 4000kg including frame, walls, ceiling construction without the weight of additional inner acoustic elements. |
Impossible to say from what you wrote. 9800 kg over what area? In loading the material, you want spring left in the material so that it does not bottom out and do nothing. Also the width wall plates to calculate the pressure is required.
