Safe, even when Rome burnsThe ignition temperature of Kerto is about 270 °C when exposed to flame. Spontaneous ignition does not occur until a temperature of over 400 °C is reached. In the event of a fire, Kerto performs more predictably than many non-combustible materials, and has a notional charring rate of 0,7 mm per minute. When burned, the surface of Kerto is charred, which protects the product, insulates it, and slows down the burning process. The fire resistance design of Kerto products is conducted according to the EN 1995-1-2 standard and its national annexes.
