Improvements in the construction of a fire-inhibiting composite element, which has internal layers of foamed organic material and mechanically stable non-combustible outer layers, characterized in that said element is composed of a central layer composed of a hydrated alkaline silicate plate, framing on both sides, respectively, a layer of foamed organic material and then, respectively, an incombustible outer layer and because at least two of the lateral surrounding surfaces of the composite element, which are not coated with the non-combustible outer layers, which are facing one another, they are covered with a mechanically stable material, not combustible, in the center of which the alkaline silicate plates have been fixed and which simultaneously act as separators for the two outer layers.
