Under extreme conditions a fire can give off flames of 50 meters or more and flame temperatures can exceed 1200°C. Aluminium is not flammable making it classified as a non-combustible construction material. This means it doesn’t ‘add fuel to the fire’. This being the case it can help prevent the spreading of fires.
Aluminium will melt when subjected to temperatures above 600°C. However, this meltdown does not release harmful gases into the air and is in fact, calculated to allow heat and smoke to escape from a burning structure. This results in less structural damage.
Non-combustible cladding is alloyed with (among other elements) magnesium, silicone, and zinc to increase its strength-to-weight ratio, corrosion resistance, and UV-shielding properties. It is the future of long-lasting buildings.
It is important, however, to be aware that not all aluminium products are of the same safe standard. For example, on its own Aluminium is non-combustible. But if it is combined with other flammable products to make up the end building material, it could result in a fire hazard.
