Our prefabricated rock wool insulation-decorative integrated panel is specially engineered for prefabricated building facade systems, integrating insulation, decoration, fire resistance, and weather resistance into one factory-prefabricated board. Featuring Class A fireproof rock wool as the core insulation layer and high-strength inorganic facing panels, the product is factory-laminated through automated production lines for precise dimensions and consistent quality.
On-site installation uses dry method with keel and hanging components—no wet work required—increasing construction efficiency by over 30%. Perfectly suited for the rapid construction and green building requirements of prefabricated projects, it has been certified as a green building material and is widely used in precast concrete structures and steel-frame prefabricated buildings.

The insulation core and decorative facing are factory-laminated in one process, eliminating risks of hollowing or detachment common with on-site bonding, ensuring precise dimensions and superior flatness.
Utilizing keel and clip connection technology, on-site installation requires only hanging and fixing—no cement mortar, no wet work—unaffected by weather, significantly shortening construction time.
The Class A non-combustible rock wool core, with a melting point above 1000°C, does not burn or emit toxic fumes during fire, providing reliable fire protection for prefabricated buildings.
The high acidity coefficient rock wool core combined with inorganic facing panels ensures excellent aging and corrosion resistance, with a service life matching the building structure and reduced maintenance costs.
Compared to traditional stone curtain wall with separate insulation, self-weight is reduced by over 60%, effectively lowering facade loads on prefabricated structures and enhancing safety.
