Introduction to Polyurethane Sandwich Panels
Polyurethane Sandwich Panels (PU Panels) are advanced insulation components designed to meet stringent energy-saving and structural requirements. PU foam’s low thermal conductivity (≈0.018–0.024 W/m·K) makes these panels ideal for environments where temperature control is critical.
Key technical characteristics:

|---|
| Core Material | High-Density Polyurethane Foam |
| Facing Options | Pre-painted steel, galvanized steel, aluminum |
| Thickness Range | 30 mm – 150 mm |
| Panel Width | Common widths: 950 mm, 1000 mm, customizable |
| Thermal Conductivity | 0.018–0.024 W/m·K |
| Density | 38–42 kg/m³ (core) |
| Fire Rating | Optional Class B to Class A2 (custom fire-resistant formulas) |
Why Choose Polyurethane Sandwich Panels
When compared to EPS, rock wool, or traditional wall materials, PU sandwich panels offer unmatched performance-to-weight ratio:
