Flame and smoke retardant barrier particularly suitable for ventilation grilles and air ducts.

摘要

A flame and smoke retardant barrier particularly suitable for ventilation grilles and air ducts, which constitute the propagation routes for fires and fumes from one room to another. The use of effective systems, which modify their structure so as to impede the transmission of fire, allows the resolution of problems associated with plant safety and the compliance of the same with regulations.
