Aluminum Alloy Great Wall Insulated Large Panel

Uses high-density polyurethane foam core with a thermal conductivity as low as 0.022 W/(m·K) to effectively block heat transfer, reducing indoor temperatures by 8-15°C in summer.

Multi-layer composite design with a polyurethane core that delivers superior sound absorption, reducing noise transmission by more than 20 decibels and ensuring silent performance even during rain.

Aluminum alloy or stainless steel face panels with B1-grade flame-retardant core deliver superior fire resistance. 70 years without deformation, 100 years without corrosion, and a service life exceeding 50 years.

Closed-cell rate exceeds 90%, effectively preventing moisture penetration and maintaining stable insulation performance over time. Ideal for coastal, high-humidity, and diverse climate conditions.

Density as low as 30-50 kg/m³: lightweight yet structurally strong. Reduces building load, simplifies transport and installation, and boosts construction efficiency by 30%.

Uses eco-friendly blowing agents with no CFC emissions, meeting green building standards. Reduces building energy consumption by over 50%, supporting energy conservation and emission reduction efforts.

Lifespan of over 50 years with stable, non-degrading performance. One-time investment delivers long-term benefits; maintenance-free design reduces long-term operating costs.

Supports custom dimensions, colors, and specifications. Available in ultra-long lengths of up to 30 meters and extra-wide panels of 980 mm to minimize seams. Meets diverse engineering customization needs.
