Product Details
Rockwool composite panels is a high-end sandwich panel designed specifically for building enclosure systems that pursue ultimate fire safety and comprehensive performance. It adopts the classic “sandwich” composite structure, with high-density color coated metal plate as the surface layer and high-quality A-grade non combustible rock wool as the core material. It is continuously compounded by high-strength adhesive, and is the core material for achieving the integration of building fire isolation, insulation and energy conservation, and structural maintenance.
Core Structure and Selected Materials
High strength surface layer
Adopting aluminum zinc or galvanized substrate, combined with excellent weather resistance PVDF/HDP coating, ensures that the sheet has excellent corrosion resistance, color durability, and decorative properties in harsh environments.
A-level fireproof core material
The core filler is high-density, hydrophobic rock wool. Rock wool is derived from natural basalt and is made by high-temperature melting and fiberization. It is an internationally recognized A1 grade non combustible material with a melting point higher than 1000 ℃. It does not burn or produce toxic smoke when exposed to fire, providing the highest level of passive fire protection for buildings.
Stable composite process
Adopting advanced fully automatic continuous production lines, precise glue distribution and high-pressure composite are used to form a solid whole between the surface layer and the rock wool core material, ensuring the strength of the board and preventing internal hollowing.

Highlight performance characteristics
Fire safety, highest level
Core advantages. Reaching the A-level non combustible standard, it can effectively block the spread of flames and meet the strict fire prevention requirements of building codes such as petrochemicals, electricity, and warehousing. It is a reliable barrier for life and property safety.
Excellent insulation, sound absorption and sound insulation
The interwoven structure of rock wool fibers contains a large amount of static air layer, with low thermal conductivity, providing stable and durable insulation performance. Meanwhile, its porous structure can effectively absorb and block sound waves, significantly reducing environmental noise.
Hydrophobic and moisture-proof, stable and durable
The core material has undergone special hydrophobic treatment, resulting in low volumetric moisture absorption and stable thermal conductivity during long-term use. It is not easily affected by moisture absorption, making it particularly suitable for high humidity environments.
Robust structure and reliable system
The board itself has high compressive and bending strength, and the metal surface layer provides excellent anti stripping performance. It can be matched with various board types and connection systems (such as hidden or exposed nail type) to form a complete enclosure system that is airtight and waterproof.
