Today, in the path toward safe construction and sustainable development, fire prevention and environmental protection have become key standards for selecting building materials. One will inevitably ask: Can rock wool catch fire? The answer is very clear and reassuring-rock wool itself does not burn and is a top-grade A1 noncombustible material.

Why Are Rocks Not Afraid of Flames? As the name suggests, the main component of rock wool is natural basalt-a sort of volcanic rock-and slag. These raw materials are melted at as high a temperature as 1500℃ and made into fibers through a centrifugal process. Therefore, the "gene" of rock wool is engraved with the characteristic of high-temperature resistance.

Extremely high melting point: Rock wool fibers usually have a melting point above 1000℃. Usually, in an ordinary building fire, the temperature will normally be below 800℃ to 1000℃. So in most fires, rock wool will keep its structure intact without melting or burning.

A1 Non-combustible Certification: According to internationally recognized standards for the classification of combustion performance of building materials, such as European EN 13501-1 and Chinese GB 8624, rock wool is rated as A1 grade, which is the highest grade among non-combustible materials. That is to say, in all stages of a fire, it will not provide any combustible material to the fire.

Data support: Not only non-combustible, but also a fire barrier

The value of rock wool lies not only in its non-combustibility but also in its ability to effectively prevent the spread of flames and heat.

Fire resistance limit: Rock wool fireproof wall and pipe covering systems can achieve a fire resistance limit up to 1 to 4 hours, thus winning precious golden time for personnel evacuation and firefighting.

Application Examples: In high-rise buildings, industrial plants, and critical fire compartments like stairwells and cable shafts, core fireproof sealing, and insulation materials such as rock wool have been widely used to ensure that a fire does not spread beyond the local area.

The connection with the environment and ecological protection

The fire safety performance of rock wool is related to ecological protection and sustainable development directly, and its environmental protection value is embodied in many aspects.

1. Enhance environmental friendliness during a building's whole life cycle: A building fire produces a great quantity of toxic gases and garbage, which seriously pollutes the environment. Using non-combustible materials such as rock wool can reduce fire hazards at their very source and lower the consumption of reconstruction resources as well as environmental pollution produced in case of fire, thus enhancing environmental friendliness during a building's whole life cycle.

2. Excellent performance in energy saving and carbon reduction: Rock wool is one of the most effective insulation materials. In winter, it can prevent indoor heat loss; in summer, it can prohibit the entry of outdoor heat. Therefore, the energy used to cool and heat the building can be greatly saved. It is believed that building energy consumption can be reduced by up to 60% when using high-quality insulation materials. Lower energy consumption directly translates to less combustion of fossil fuel and carbon dioxide emissions, which is an effective way to deal with climate change and realize the "dual carbon" goals.

3. Recycling of resources: In modern production, rock wool uses a large quantity of industrial by-products such as blast furnace slag as raw materials, thus waste is converted to treasure. Meanwhile, the service life of rock wool products is very long, as long as that of buildings. In addition, some wastes of rock wool could also be recycled for use in new production processes, which meets the principles of a circular economy.

To sum up, rock wool does not catch fire; more so, it constitutes the cornerstone of the construction of safe and green buildings. In addition, U-ROOKPAN and U-ROCKROL series provides a solid guarantee for life and property safety with its A1-level non-combustible property, while making a direct contribution to the global energy conservation and emission reduction cause. Thus, rock wool is no doubt a kind of scientific choice in building materials which integrates safety, energy conservation, and environmental protection, and it is the key force to push the construction industry into a safer and more sustainable future.
