A1 Non-combustible Rockwool Sandwich Panel PPGI Color Steel Rock Wool Insulated Panel For Prefab Building Partition

Our Rock Wool Sandwich Panel is composed of high-density rock wool core and double-sided PPGI/galvanized steel sheets. As A1 non-combustible building material, it offers superior fire resistance, thermal insulation, and acoustic performance.

With tongue-and-groove connection, the panel is lightweight and easy to install. It is widely applied for exterior walls, roofs, and internal partitions of steel structure workshops, warehouses, prefabricated buildings, and commercial projects. Custom sizes, colors, and PU edge sealing are available to meet different project requirements.

• Excellent fireproof, heat-insulating, and environmentally friendly characteristics
• Ideal for industrial building enclosure systems
• Specifically designed for cold rooms and warehouse applications
• Modern design with superior structural integrity

The core material consists of artificial inorganic fiber made from high-quality natural rocks such as basalt and gabbro as primary raw materials. These materials are melted and fiberized at high temperature, resulting in extremely low slag and dust content with non-absorbent properties - representing genuine "real rock wool" quality.
