Metal roofing structures are often exposed to the outdoor environment and are subject to significant temperature fluctuations, necessitating insulation materials to improve indoor comfort and reduce energy consumption. Rock wool insulation boards possess excellent fire resistance, heat insulation, and sound absorption properties, making them frequently used in metal roofing systems.

The uniform fiber structure of rock wool boards forms a stable insulation layer within the roof structure, helping to reduce heat entry into the room during summer and heat loss during winter. Furthermore, rock wool boards exhibit good dimensional stability, maintaining structural integrity under external forces and resisting shrinkage or deformation.

In metal roofing construction, rock wool boards are typically laid between the upper metal sheet and the lower structure, in conjunction with a waterproof layer and fixing system to enhance overall durability. During installation, attention should be paid to ensuring smooth cut edges and a dense, continuous installation. Due to its comprehensive performance, rock wool insulation boards have become a common insulation choice for metal roofs.
