A prefabricated floor and ceiling panel, with a bearing structure formed of a metal structure (1, 2, 3) which is completely incorporated in a matrix (10) of heat-insulating and sound dampening material made from a mixture of super-light grains (preferably coming from or ground recycled materials) with just a small amount of aerial type binder; said panel is immersed above and/or below in the same heat-insulating and sound dampening matrix (10) that contains the metal bearing structure (1, 2, 3), the coil (4, 4') for the circulation of the heating fluids for the floor heating system and cooling fluids for the ceiling cooling system. |
