Abstract: The present invention relates to a method for making a composite panel comprising a pourable and settable base material, preferably cementitious mortar, and a plurality of through elements (10) made of glass for transmitting light between two base surfaces (1,1?) of the panel (1). The method includes making a semi-finished product comprising a central body (50) which incorporates the through elements (10), which emerge from two mutually opposite main surfaces (51,52). In particular, the method includes making the semi-finished product by defining two containing frames, mutually opposite with respect to the body, each of which emerges from one of the central surfaces. The method includes closing the semi-finished product between two containing elements so as to define two half-spaces, each of which at least partially delimited by said containing frames. The method then includes filling each half-space with cementitious mortar and removing the manufactured item which is made, after the mortar has set.
