Rock wool board is widely used as insulation material in large steel structure buildings due to its excellent insulation performance and fire resistance characteristics. These boards can effectively reduce heat loss, maintain a constant indoor temperature, thereby reducing energy consumption and improving energy efficiency. In addition, the high bulk density and low thermal conductivity of rock wool board make it excellent in isolating external low or high temperature influences. During the construction process, rock wool board can be easily installed on the surface of the steel structure, forming a strong insulation layer, while also providing necessary fire protection for the building, ensuring the integrity of the structure and the safety of personnel in case of fire. Due to these characteristics of rock wool boards, they have become an ideal insulation solution for steel structure buildings such as large industrial facilities, warehouses, exhibition centers, etc.
