In the modern industrial and commercial construction sector, Rock Wool Sandwich Panels are the gold standard for fire safety, acoustic insulation, and thermal efficiency. As the “heart” of the panel, the core material dictates the structural integrity and market competitiveness of the final product.
Corporación de materiales de construcción Jinan United Perfect, a global leader in insulation technology, presents its flagship brand, OPERFECT™.—specifically engineered to meet the rigorous demands of sandwich panel production facilities worldwide.
1. Specifications & Dimensions: Engineered for Modern Production
Efficiency is the lifeline of any manufacturing plant. OPERFECT™. rock wool slabs offer unparalleled flexibility in sizing:
- Standard Large Format: Available in 4ft x 8ft (1220mm x 2440mm) dimensions, perfectly compatible with global continuous and non-continuous production lines to minimize cutting waste.
- Full Customization: Beyond standard sizes, our advanced automated lines allow for precise customization of thickness, length, and width to meet specific modular requirements for roof, wall, or cold-room panels.
2. Technical Benchmarking: Exceeding Global Standards
Sandwich panel core material requires higher mechanical performance than standard building insulation. OPERFECT™. delivers on every critical metric:
| Key Indicators | OPERFECT™ Performance | Industry Value |
| Fire Reaction | Class A1 Non-combustible | Meets the highest global fire safety regulations. |
| Conductividad térmica | $\le 0.038 – 0.040 W/(m \cdot K)$ | Maximizes R-Value and building energy efficiency. |
| Hydrophobicity | $\ge 98\%$ | Prevents moisture ingress, core failure, and skin corrosion. |
| Shot Content | $\le 6\%$ (Diameter >0.25mm) | Enhances fiber bonding for an ultra-flat panel surface. |
| Compressive Strength | Up to $100$ kPa+ (Customizable) | Ensures structural stability against high wind loads. |
