In a fire situation, a deployed fire shutter can turn red-hot when subjected to the full force of the flames and intense heat can radiate from the shutter curtain. This radiated heat is capable of igniting combustible materials that may be stored on the other side, hence allowing the fire to spread. The solution to this is the use of Fire Insulated Shutters.
