PU Foam Sandwich Panel
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 polyurethane (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: 48-52kg/CBM
Panel Dimension: 3950mm*1200mm*20mm
Alu. Foil: 60 or 80 Micron (Embossed)
Fire Rating: Class 0 (BS476Part 6&7)

Process Characteristics of PU Foam Sandwich Panel
Integrated molding: The imported high-pressure foaming machine is used for one-time injection, eliminating the cavity issues of manual foaming. The core material is closely bonded with the panel, resulting in strong overall integrity.
Panel customization: Seven material options are available, including corrugated steel, stainless steel, and embossed aluminum. Coatings such as HDP/PVDF can be selected, offering corrosion resistance and UV protection, and meeting the 1000-hour salt spray test standards.
Precision control: German cutting and Italian bending equipment ensure a ±0.5mm assembly accuracy, with tight board seams and improved air tightness by 30% compared to traditional processes.
Economy of PU Foam Sandwich Panel
Energy conservation and reduction: The high-quality PU board reduces the annual energy consumption of the cold storage by 12% - 18%. For a 1,000㎡ cold storage, the annual electricity savings amount to 20,000 - 30,000 kWh, and the initial cost difference can be recovered within 2 - 3 years.
Installation efficiency: Modular connection shortens the construction period by 40%, eliminating complex procedures and reducing labor costs. Maintenance in the future only requires regular checks of the sealing glue and panel coating.
Life cycle: Low maintenance requirements. Normal use can last for more than 10 years. For the renovation of old cold storages, an incremental insulation solution is adopted, reducing energy consumption by more than 34%.
