Technical details and manufacturing context for Insulated Panels
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Thermal Conductivity | 0.022–0.028 W/(m·K) | Lower is better for insulationASTM C518 |
| Compressive Strength | 150–250 kPa | Minimum for structural applicationsASTM C165 |
| Density | 38–42 kg/m³ | Affects weight and handlingASTM D1622 |
| Panel Thickness | 50–200 mm | Common range for wall/roof panels |
| Panel Width | 1000–1200 mm | Standard modular widths |
| Panel Length | 2000–12000 mm | Custom lengths available |
| Fire Resistance | B–A2 class | A2 is non-combustibleEN 13501-1 |
| Water Absorption | ≤2.0 % | Low absorption prevents moisture damageASTM C272 |
| Service Temperature | -40–80 °C | Exceeding range may degrade insulation |
| Surface Finish | PVDF, HDP, PE | PVDF offers best weather resistance |
| Core Material | EPS, XPS, PUR | PUR has highest insulating value |
| Weight | 10–25 kg/m² | Depends on thickness and core |
Ranges are indicative industry figures for RFQ preparation, not a supplier commitment. Confirm every value and standard with the legal manufacturer before ordering.

Insulated panels are used as wall and roof elements to create a controlled environment inside tunnel housing structures. They provide thermal insulation, structural integrity, and protection against external conditions, helping maintain consistent internal temperatures for industrial processes.
Common core materials include polyurethane (PUR), polystyrene (EPS/XPS), and mineral wool. Facing materials typically include galvanized steel, aluminum, or composite sheets. The specific combination affects thermal performance, fire resistance, and durability.
Reference ranges include thermal conductivity of 0.022–0.028 W/(m·K), compressive strength of 150–250 kPa, density of 38–42 kg/m³, and water absorption ≤2.0%. Panel thickness ranges from 50–200 mm, width 1000–1200 mm, and length 2000–12000 mm. Fire resistance class ranges from B to A2. These values must be verified for specific models.
Regular inspection for damage, moisture ingress, and seal integrity is recommended. Signs of failure include delamination, corrosion, or reduced insulation efficiency. Any damaged panels should be repaired or replaced promptly. Always follow manufacturer guidelines for maintenance and installation.
