ABSTRACT OF THE DISCLOSURE The invention pertains to the containment of fire within ventilation ducts in a building. To this end, a lattice consisting of highly thermally conductive material, such as expanded metal, is placed in the cross section of the ventilation duct, said lattice then conducting the heat to the walls of the ventilation duct and is thereby able to prevent or delay the passage of the flames. Since such a lattice becomes fouled during operation of ventilation system, it must be easy to replace and clean. For this reason, it is recommended that the particle filling, in the form of bulk expanded metal balls, be placed on a rigid midplane consisting of transverse supports or perforated plates, etc.
