Rock wool board used for housetop mainly plays the role of heat preservation, heat insulation, fire prevention and sound insulation. The difference between housetop rock wool board and ordinary rock wool board is hydrophobicity. Because the housetop has to withstand the impact of rain, the Rooftop Rock Wool Panel must be a rock wool board with a higher hydrophobicity rate, and a waterproof layer must be made during construction! The artificial inorganic fiber processed by Yu Ou Nuo Rock Wool Board For House Top through high temperature melting has the characteristics of light weight, low thermal conductivity, heat absorption and non-combustibility. The initial development is a common application type in construction, and it should meet the requirements of " Application Types and Basic Requirements of Building Thermal Insulation Materials".
