High-Density Polyurethane Blocks: Structural Thermal Break for LNG, Passive House & Curtain Walls

Polyurethane (PUR/PIR) Insulation Blocks are high-performance structural components engineered to eliminate thermal energy transfer in load-bearing applications. At Hebei Woqin, we utilize advanced high-pressure foaming technology to create a rigid, nanoporous matrix with a closed-cell rate exceeding 95%. With a thermal conductivity as low as 0.08 W/(m·K), these blocks serve as the ultimate "Thermal Break" for mission-critical infrastructure.

Strategic Application Sectors:

• Cryogenic & Industrial Piping (LNG/LPG): Designed for extreme environments down to -196°C. Our blocks provide high-strength support for cryogenic pipelines, preventing ice formation and energy loss while maintaining dimensional stability under heavy mechanical loads.
• Passive House & Sustainable Architecture: In modern green buildings, our blocks are essential for foundation nodes and structural connections. By effectively cutting the "Cold Bridge," they prevent internal condensation and mold growth, ensuring the building envelope meets the strictest Passive House energy standards.
• Curtain Wall & Facade Engineering: Specifically optimized for embedded plates and structural brackets. These blocks withstand significant wind and dead loads of glass facades while isolating the thermal path between the exterior and the building's interior skeleton.

Engineering Excellence & Specifications:

• Extreme Compressive Strength: Capable of withstanding up to 8MPa, ensuring that structural supports do not settle or deform over decades of service.
• Thermal Versatility: Maintains peak performance across a wide operating range from -196°C to +120°C, making it suitable for both sub-zero cryogenics and high-heat industrial rooftops.
• Fire Safety & Durability: Fully compliant with Class B1 (GB 8624) and Class A (ASTM E84) flame retardancy. The inorganic nature of the polymer ensures resistance to chemical corrosion and near-zero water absorption.

As a premier manufacturer, Hebei Woqin offers precision-machined polyurethane blocks tailored to your exact 3D CAD drawings. Whether you are designing a high-precision facade or a global energy terminal, our structural thermal breaks provide the reliability, safety, and energy efficiency required for 21st-century engineering.
