Product Introduction
Rock Wool Sandwich Panel
This panel has two corrosion resistant steel sheets on the outside. The core is high density rock wool. This structure gives you A2 fireproof protection, great thermal insulation, and strong sound absorption. The steel faces add mechanical strength and impact resistance. You can use it for walls, roofs, and partitions in warehouses, factories, and prefab buildings.
