What Are Fire Protection Sandwich Panels
Fire protection sandwich panels are construction materials designed to provide strong fire resistance while offering excellent insulation. These panels consist of two outer metal sheets bonded to a core material that acts as a fire barrier and thermal insulator. The core plays a crucial role in fire safety by slowing down heat transfer and preventing flame spread.
Common core materials used in fire-resistant sandwich panels include rockwool, PIR (polyisocyanurate), and mineral wool. Rockwool and mineral wool are non-combustible and excel at resisting high temperatures, making them top choices for fire safety. PIR cores combine good fire performance with superior thermal insulation, trusted in many commercial and industrial applications.
Fire resistance ratings such as EI30, EI60, and EI120 indicate how long a panel can withstand fire exposure—30, 60, or 120 minutes respectively—helping designers meet specific safety requirements. These ratings are tested according to standards like EN 13501 in Europe and ASTM E84 in the United States, ensuring consistent performance and reliability.
At Shanghe, we are committed to meeting the highest global safety standards. Our fire protection sandwich panels undergo rigorous testing and certification to ensure they deliver dependable fire resistance for your projects worldwide.

Benefits of Shanghe Fire Protection Sandwich Panels
When it comes to fire safety, Shanghe panels stand out. Their cores often use non-combustible materials like rockwool, which means they don’t catch fire easily and help slow down flame spread. This quality is crucial for keeping buildings safer during emergencies.
Beyond fire resistance, these sandwich panels offer excellent thermal insulation and acoustic benefits. They help keep indoor temperatures steady, reducing energy costs, while also cutting down on noise — a big plus for both commercial and residential spaces.
Durability is another strong suit. Shanghe’s panels are built to last, supporting heavy loads without losing strength over time. This makes them a reliable choice for walls, roofs, and partitions that need to withstand tough conditions.
Sustainability matters too. Shanghe uses eco-friendly materials like CFC-free PIR cores, which reduce environmental impact without sacrificing performance. This aligns well with green building practices popular across the U.S.
Finally, these fire protection sandwich panels save money over the long haul. Their energy efficiency lowers heating and cooling bills, and their low maintenance needs cut repair costs, making them a smart investment for any project.
Applications of Fire Protection Sandwich Panels
Fire protection sandwich panels are a smart choice for a wide range of projects across the U.S. They’re commonly used in:

Comparing Core Materials Which Is Best for Fire Protection
When choosing fire protection sandwich panels, the core material plays a huge role in performance. Let’s compare the most popular cores: rockwool, PIR, polyurethane (PU), and EPS (expanded polystyrene) across fire resistance, insulation, and cost.
| Core Material | Fire Resistance Rating | Thermal Conductivity (W/m·K) | Applications | Cost |
|---|
| Rockwool | EI60 to EI120 (non-combustible) | 0.035 – 0.045 | Industrial, warehouse walls, fire-rated partitions | Moderate |
| PIR | EI30 to EI60 (limited combustibility) | 0.022 – 0.028 | Commercial roofing, cold storage, walls | Moderate-High |
| Polyurethane | Low fire resistance (combustible) | 0.020 – 0.025 | Insulation where fire risk is low | Lower |
| EPS | Low fire resistance (combustible) | 0.030 – 0.040 | Budget projects, non-fire-rated applications | Low |
Rockwool sandwich panels are top for fire safety because they are non-combustible and provide excellent insulation. PIR panels come in a close second with good fire ratings and better thermal insulation, making them a smart choice when fire safety and energy efficiency matter.
