  • What is PU Panel?

    PU (Polyurethane) Panel is a high-performance sandwich panel made of two outer steel sheets with a rigid polyurethane foam (PUF) core. Known for its superior thermal insulation, lightweight design, and excellent durability, PU panels are widely used in prefab house wall systems. The PU core acts as an efficient thermal barrier, while the steel surfaces provide strength, protection, and an attractive finish.

  • Properties of PU Panels

    Superior Thermal Insulation

    PU foam has one of the lowest thermal conductivity values among insulation materials, ensuring maximum energy savings.

    Lightweight & Strong

    The rigid foam core keeps the panel lightweight without compromising structural strength, reducing building load.

    Moisture & Water Resistance

    PU foam has a closed-cell structure, making it highly resistant to moisture, water absorption, and mold growth.

    Fire Performance

    PU panels can be manufactured with fire-retardant additives, improving safety and compliance with building standards.

    Durability

    Resistant to aging, weathering, and chemical corrosion, ensuring long-lasting performance.

    Aesthetic Flexibility

    Available in different surface finishes and colors to match architectural needs.

  • Common Specifications

    PU panels are often customized to meet specific needs, but some common specifications include:

    Thickness

    Available in 50 mm, 75 mm, and 100 mm

    Width

    Standard effective width 950 mm or 1150 mm

    Length

    Custom lengths up to 12 m, based on project requirements

    Steel Sheet

    Pre-painted galvanized steel (PPGI) or aluminum-zinc coated steel, 0.4 – 0.6 mm thick

    Core Density

    Typically 35 – 45 kg/m³ for PU foam

    Surface Options

    Flat or corrugated steel facings, available in multiple coatings and colors

  • Applications

    PU Panels are widely used in prefab construction and industrial projects, including:

    • Prefab House Walls & Partitions – energy-efficient wall systems for residential and modular housing
    • Cold Storage & Refrigerated Rooms – due to excellent insulation and moisture resistance
    • Commercial Buildings – office walls, shopping centers, and modular units
    • Industrial Facilities – warehouses, cleanrooms, and production facilities requiring controlled environments

  • Conclusion

    PU Panels provide exceptional insulation, moisture resistance, and durability, making them one of the most efficient wall materials for prefabricated housing. Their combination of strength, lightweight design, and energy-saving performance ensures long-term reliability and comfort.
