Polyurethane Insulation Board
It is a high-performance ventilation duct product, which is widely used in HVAC systems. The following is a detailed introduction:
Basic Structure: It is a sandwich structured panel. The core is polurethane (PU) foam, which is a closed-cell insulating material. The two outer layers are aluminum sheets or aluminum foils.
Panel Structure: Silver Alu. Foil/ PU Foam/ Silver Alu. Foil
Foam Density: 50kg/CBM
Panel Dimension: 3950mm*1200mm*20mm or 2900*1200*20mm
Alu. Foil: 60 or 80 Micron (Embossed)
Fire Rating: Class 0 (BS476Part 6&7)
Core Performance Advantages of Polyurethane Insulation Board
Ultimate insulation efficiency: The thermal conductivity is only 0.018-0.023w/(m · k), far lower than that of polystyrene (0.030-0.040w/(m · k)) and rock wool (0.040-0.050w/(m · k)). Under the same insulation requirements, it can reduce the thickness of the maintenance structure and increase the indoor usable area.
All-scenario adaptability: Closed-cell rate exceeds 95%,compressive strength ≥160kpa, dimensional stability ≤3%, capable of resisting freeze-thaw, corrosion and biological damage, suitable for complex environments such as high temperature, high humidity and low temperature.
Safety and environmental protection guarantee: The combustion performance reaches B1 grade. During combustion, a carbonized layer is formed to block the flame, and no harmful gases are released.
Long-lasting durability: Formed by high-pressure foaming process, the thickness error is only ±0.5mm. The concave-convex groove structure enhances air tightness. Under normal use and maintenance, the service life exceeds 30 years, far exceeding that of traditional insulation materials.

Market Development Trends of Polyurethane Insulation Board
Rapid expansion in scale: The global market size is expected to exceed 38 billion US dollars by 2025, with China accounting for nearly 45%, and the compound annual growth rate remains above 6%. The North China and East China regions are leading the demand due to strict energy-saving standards.
Competitive landscape differentiation: Leading enterprises strengthen their production capacity advantages through mergers and acquisitions and integration, while small and medium-sized enterprises focus on niche fields. China is the largest exporter, accounting for 35% of global exports, which mainly flow to Southeast Asia, the Middle East and Africa.
Diversified growth drivers: The deepening of building energy conservation policies and the expansion of cold chain infrastructure are the core driving forces, while the upgrading of industrial equipment and the trend of automotive lightweighting further open up incremental space.
Environmental Protection and Economy of Polyurethane Insulation Board
Green production and usage: Production is carried out in accordance with the JB/T6527-2006 standard, and fluorine-free foaming process is adopted to reduce environmental impact. It significantly reduces the energy consumption for heating and cooling during use, contributing to the achievement of the carbon neutrality goal.
Outstanding overall cost performance: Although the unit price is higher than that of traditional materials, the insulation efficiency is increased by more than 30%, and the long-term energy consumption cost savings can offset the initial investment. Compatible with modular installation, it shortens the construction period and reduces labor costs.
Policy dividends support: The mandatory implementation of domestic green building standards and energy conservation and emission reduction policies, as well as the continuous release of demand for energy-saving renovations of existing buildings and new construction projects, provide stable market support for products.
