Common Core Types & Their Benefits
| Core Material | Key Features |
|---|---|
| PU (Polyurethane) | Best insulation, lightweight, fire-resistant (Class B), ideal for cold rooms and factories. |
| EPS (Polystyrene) | Low-cost, lightweight, basic insulation, not fire-resistant. |
|
Rock Wool/Glass Wool
|
Fireproof (Class A), sound-absorbing, heavy, perfect for fire-rated walls.
|
| Material | Fire Resistance | Thermal Insulation (W/(m·K)) | Weight (Density, kg/m³) | Relative Cost | Application Scenarios | Notes | |
| Rock Wool Board | Excellent (Class A non-combustible) | 0.040–0.045 | 80–200 | High | High-rise building exteriors, fire barriers, industrial plants, fire-sensitive environments. | Best fire resistance but absorbs moisture; requires moisture-proof treatment. | |
| EPS Board | Poor (Class B2 combustible) | 0.035–0.043 | 15–30 | Lowest | Temporary structures, low-rise residential interiors, refrigerated trucks, packaging (with fire retardants). | Cost-effective but flammable; deforms at high temperatures. | |
| PU Board | Good (Class B1/B2) | 0.020–0.024 | 30–50 | Highest | Cold chain logistics, refrigerated warehouses, high-end building exteriors, low-temperature pipelines. | Best insulation; fire resistance can be upgraded to B1 with additives. | |
| Glass Wool Board | Excellent (Class A non-combustible) | 0.042–0.048 | 60–150 | Medium | Pipe insulation, equipment thermal barriers, acoustic partitions, non-load-bearing fire barriers. | Fire-resistant but slightly less insulating; fibers require handling care. |

When it comes to construction and industrial applications, choosing the right materials is crucial for durability, energy efficiency, and cost-effectiveness. Sandwich panels (or composite panels) have become a popular alternative to traditional building materials like concrete, brick, and single-layer metal sheets. But what makes them different, and why are they gaining popularity? Let’s explore the key advantages of sandwich panels over conventional options.
