QueenCore’s Rock Wool Sandwich Panel is a high-performance building material designed for superior fireproof, waterproof, and insulated applications. Ideal for industrial, commercial, and residential projects, our panels provide exceptional thermal insulation, soundproofing, and structural stability while meeting stringent safety and environmental standards.
Raw Materials
Our Rock Wool Sandwich Panels are manufactured using:
- Core Material: High-density rock wool (stone wool) for excellent fire resistance (Grade A Fireproof) and thermal insulation.
- Outer Layers: Galvanized steel or aluminum coated with protective films for durability and waterproofing.
- Adhesive: High-strength polyurethane (PU) or epoxy-based adhesive for robust bonding.

Manufacturing Process
- Material Preparation: Rock wool is compressed and treated for fire resistance.
- Panel Formation: The core is sandwiched between two metal sheets.
- Bonding: High-pressure lamination ensures strong adhesion.
- Curing & Cutting: Panels are cured for stability and precision-cut.
- Quality Inspection: Each panel undergoes fireproof, waterproof, and load-bearing tests.
Applications
QueenCore’s Rock Wool Sandwich Panels are widely used in:
- Industrial Buildings (Warehouses, Factories)
- Commercial Spaces (Shopping Malls, Offices)
- Residential Projects (Prefab Houses, Partition Walls)
- Cold Storage & Clean Rooms (Insulated Walls & Roofs)
- Fireproof Partitions (Hospitals, Data Centers)
Installation Guide
- Preparation: Ensure the frame is level and secure.
- Panel Alignment: Place panels vertically/horizontally with proper overlap.
- Fixing: Use self-tapping screws or rivets at recommended intervals.
- Sealing: Apply waterproof sealant at joints for enhanced protection.
- Finishing: Trim edges and inspect for gaps.
FAQ (Frequently Asked Questions)
Q: Are Rock Wool Sandwich Panels fireproof?
A: Yes! Our panels are Grade A Fireproof, offering superior resistance to flames and high temperatures.
Q: Can these panels be used in humid environments?
A: Absolutely. The waterproof (IP65) design prevents moisture absorption, making them ideal for cold storage and coastal areas.
Q: How do Rock Wool Panels compare to EPS or PU panels?
A: Rock Wool provides better fireproofing and sound insulation than EPS/PU, though slightly heavier.
Q: Is customization available?
A: Yes! QueenCore offers custom sizes, thicknesses, and surface finishes.
Q: What’s the lifespan of these panels?
A: With proper installation, they last 20-30 years due to corrosion-resistant coatings.
