Structure: The 100mm 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 12mm gypsum boards. Manufactured through heating, pressing, and curing processes.

Core material: Rock wool (density 100 kg/m³, ≥120 kg/m³ optional) + double 12mm gypsum boards · Application: Cleanrooms, hospitals, pharmaceutical plants, high‑fire‑risk areas, partitions requiring superior fire resistance (up to 4 hours) and excellent thermal insulation.
