FIRE RESISTANCE
Yes, the wood burns and no one contests this statement but it burns at a speed of 0.70mm/minute, and after 30 minutes of burning, the ash deposited on it does not let the fire spread further. The formed ashes protect the rest of the wood from fire propagation. Generally, the fire affects all construction materials in different ways, even if a certain structure does not burn, it has always a reaction: steel loses half of its strength and becomes yielding at 800 Celsius degrees, the concrete cracks and peels and so on with all the material we look at, each one reacts to fire in its own way. For the wooden houses, there are woodfire protection treatments that increase the resistance and controls the fire behaviour by delaying the burning rate of the wood.
