ABSTRACT OF THE DISCLOSURE The invention concerns a composite assembly forming a thermal protection or dissipation screen comprising a hot wall and a cold wall, wherein it includes between said hot wall and said cold wall at least two adjacent elements called vaporizer superheaters of a refractory material, each comprising within itself a socalled reactive substance capable of releasing at a given temperature specific to each element a non flammable gas or vapor, each of said elements being separated from the other by a wall sealed from the temperature of release of vapor or gas of the element located the closest to said hot wall but capable of becoming porous as soon as such temperature is exceeded, each element due to the presence of said reactive substance evolving from the vaporizer function to the superheater function depending on development of the thermal aggression to which it is submitted.
