Structure: The 50mm metal‑faced double gypsum+rock wool manual sandwich panel consists of pre‑painted steel or stainless steel facings, edges sealed with galvanized steel strips and corner pieces. The core is rock wool + double 9.5mm gypsum boards (one on each side of the rock wool). Manufactured through heating, pressing, and curing processes.

Core: Rock wool (density 100 kg/m³, ≥120 kg/m³ optional) + double 9.5mm gypsum boards · Application: Cleanrooms, hospitals, offices, partitions, areas requiring excellent fire resistance and acoustic insulation.
