We produce the Sandwich Panel Core Rock Wool as a core material for composite sandwich panels, using high-strength basalt fibers processed through a special bonding technique. As a manufacturer collaborating with numerous sandwich panel producers, we understand the need for structural stability, fire resistance, and insulation-critical for building envelopes. The rock wool core features uniform density and high compressive strength, ensuring it bonds firmly with metal or concrete facings. It is non-combustible and dimensionally stable, maintaining its shape under temperature changes and mechanical stress.

Why Choose Us
Our rock wool core has a bonding strength of ≥0.15 MPa with metal facings, reducing delamination risks for sandwich panel producers.
We offer large-format production (up to 1200×600×200mm), minimizing joint gaps in sandwich panels and improving efficiency.
Stable production capacity of 50,000 m³ monthly meets bulk order requirements of panel manufacturers, ensuring supply chain stability.
Custom density options (120-180 kg/m³) adapt to different structural load requirements of sandwich panels.
We provide technical data sheets compatible with common panel production lines, facilitating integration into clients' manufacturing processes.
FAQ
Q: Can the Sandwich Panel Core Rock Wool be used for exterior wall sandwich panels?
A: Yes. With a hydrophobicity rate of ≥98.0% and compressive strength ≥80 kPa, it resists weathering and structural stress. We recommend pairing it with waterproof facings for outdoor applications.
Q: What is the maximum thickness available for this core material?
A: We offer thicknesses up to 200mm, suitable for cold storage and other applications requiring high insulation performance.
Q: How to ensure the core material bonds well with metal facings?
A: We recommend using polyurethane or epoxy adhesives, and maintaining a core temperature of 15-25℃ during bonding. Our technical team can provide adhesive compatibility testing upon request.
