IFS83/IFS82 is a composite sheet mainly composed of a metal panel and a fire-resistant expanding rubber layer. In a fire, it can rapidly expand to form an insulating layer to prevent heat from spreading. At the same time, the huge expansion pressure can quickly seal the gaps left by the burning combustibles to prevent the spread of fire.
