First, in terms of fire resistance, rock wool board is a Class A non-combustible material with a melting point of more than 1000℃. It does not burn when exposed to fire and does not produce toxic smoke. It can effectively prevent the spread of fire, which is far superior to organic insulation materials such as polystyrene board and polyurethane. Therefore, rock wool board is widely used in projects with extremely high fire protection requirements such as high-rise buildings and public buildings.
Secondly, in terms of thermal insulation performance, rock wool board has low thermal conductivity and good thermal stability. Its fiber structure is fine and uniform, which can effectively reduce heat loss and improve building energy efficiency. At the same time, rock wool board also has good sound absorption and noise reduction functions, which helps to improve indoor comfort. Its application value in airports, highways, schools and other places is more significant.
In addition, rock wool board has good dimensional stability and hydrophobicity. It can still maintain excellent physical properties in hot and cold alternation and humid climate. It is not easy to deform or mildew, which greatly extends the service life of the building insulation system. In contrast, some foam materials have problems such as low ignition point, easy aging and poor durability.
From an environmental protection perspective, rock wool board uses natural basalt as raw material, is non-toxic and harmless, can be recycled, and conforms to the concept of sustainable development. In construction applications, it is easy to cut and install, which further improves construction efficiency.
In summary, rock wool board has excellent performance in safety, energy saving, durability, environmental protection and other aspects, and is an ideal choice for modern building insulation systems. With the continuous improvement of building standards, the market demand and industry status of rock wool board will continue to rise.
