In the field of modern construction, the selection of exterior wall insulation materials is crucial. It is not only related to the energy saving and consumption reduction of buildings, but also closely related to the safety of buildings. Among many insulation materials, rock wool board has won wide attention and application with its unique performance, especially its excellent fireproof performance.1. Fireproof grade and characteristics of rock wool boardRock wool board is an inorganic fiber material, which is mainly made of natural minerals such as basalt after high-temperature melting and fiberization. This material has significant advantages in the field of building insulation due to its non-combustibility, high temperature resistance and low thermal conductivity. As the preferred material for exterior wall insulation, rock wool board usually has a fireproof grade of A, which is the highest grade of fireproof material.The fireproof performance of rock wool board is mainly reflected in the following aspects:Non-combustibility: The main raw material of rock wool board is natural minerals such as basalt, which has a melting point of more than 1000℃. It will not burn even at high temperatures and can effectively prevent the spread of flames.Thermal insulation: rock wool board has good thermal insulation performance, and its low thermal conductivity means that it can effectively reduce the speed of heat propagation when a fire occurs, protecting the building and its internal structure from high temperature damage.Non-toxicity: In a fire, rock wool board will not produce smoke or release toxic gases, which is crucial for the evacuation of personnel and fire rescue.Dimensional stability: rock wool board is dimensionally stable at high temperatures, not prone to deformation or shrinkage, and can maintain the integrity of the building structure, playing an effective role in fire isolation.2. Application of rock wool board in exterior wall insulationRock wool board is widely used in building exterior wall insulation systems due to its excellent fireproof performance. Especially in places with high fire risks such as high-rise buildings, industrial plants, and tunnels, rock wool board has become the preferred insulation material.High-rise buildings: In high-rise buildings, rock wool board, as an exterior wall insulation layer, can form a solid fire barrier. Once a fire occurs, rock wool board can effectively prevent the flames from spreading to the upper floors, buying precious time for personnel evacuation and fire rescue.Industrial plant: Industrial plant usually contains a large number of equipment and production lines. Once a fire occurs, the consequences are disastrous. Rock wool board, as equipment insulation and fireproof isolation material, can significantly reduce the risk of fire and protect the safety of equipment and personnel.Tunnel: As a major traffic route, the safety of the tunnel is of vital importance. Rock wool board is widely used in the fireproof and thermal insulation system of the tunnel, which can effectively improve the fireproof level of the tunnel and ensure driving safety.3. Safety benefits brought by the fireproof performance of rock wool boardThe fireproof performance of rock wool board in exterior wall insulation not only improves the fire resistance limit of the building, but also provides a strong guarantee for the safety of personnel and property. When a fire occurs, rock wool board can effectively block the spread of flames, slow down the development of the fire, and buy time for fire rescue. At the same time, rock wool board does not produce toxic gases, providing a relatively safe environment for personnel evacuation.In addition, the fireproof performance of rock wool board also reduces the fire risk of the building and improves the overall safety of the building. This is of great significance for protecting people's lives and property and maintaining social stability.In summary, rock wool board has good fireproof performance in exterior wall insulation. Its non-combustibility, heat insulation, non-toxicity and dimensional stability make rock wool board a leader in the field of building insulation. The application of rock wool board not only improves the fire resistance limit of the building, but also provides a strong guarantee for the safety of personnel and property.
