In the evolution of building envelope systems, we have always adhered to a core philosophy – truly superior building materials should originate from nature and return to nature. ZHUOZHU rock wool sandwich panels, with natural basalt as the core material and metal sheets as the protective layer, provide truly healthy and safe comprehensive system solutions for modern construction.

Natural Rock Wool Core: The Sublimation Journey of Pure Basalt
At the heart of every ZHUOZHU rock wool sandwich panel lies a gift from the depths of the earth – natural basalt. This volcanic rock, formed through hundreds of millions of years of geological evolution, is reborn through melting at 1500°C and transformed into high-performance rock wool fibers using advanced centrifugal fiberization technology. The entire process only changes the physical form of the material while preserving its natural essence, ensuring the purity and safety of the core material.
Three Zero-Additive Commitments
- Zero Formaldehyde: From rock wool core to finished panels, complete elimination of formaldehyde additives throughout the process, ensuring indoor air quality safety
- Zero Asbestos: Uses pure natural basalt raw materials, absolutely no asbestos components
- Zero CFCs: Complete avoidance of ozone-depleting chlorofluorocarbons in the production process
