Products Description
Camlock puf panel is the best material for modern cold chain. It is not only easy to install and disassemble, but also has excellent insulation effect. The unique cam lock process increases the installation efficiency by 40%, and the panels are seamlessly connected to effectively prevent the formation of cold bridges.
This product adopts a sandwich structure design. The outer surface is made of color steel or stainless steel and other metals. The color can be customized. The inner filling is polyurethane foam. The thickness can be selected from 50-250mm. It is mainly used in various temperature control environments. The service life exceeds 15 years. Element can provide customers with a 5-year long warranty period. When purchasing panels, you need to pay attention to the temperature and matching plate thickness, as well as the metal finishing layer requirements of the plate, such as anti-corrosion performance and cleanliness performance.
Correct installation and regular maintenance can maximize product performance and ensure long-term stable operation of the cold storage.

Factory Production
Continuous Lamination: PU/PIR foam is injected between metal facings (pre-painted steel/SS304) under controlled pressure, ensuring uniform density and adhesion 12.
Cam Lock Edge Formation: Precision cutting molds the interlocking edges for airtight assembly; automated systems maintain ±1mm tolerance 1.
Surface Treatment: Metal sheets are pre-coated with anti-corrosion layers (e.g., PVDF for UV resistance) 2.
Quality Control: Includes mechanical stress tests and thermal performance verification 2.
Material Structure: Sandwich panel design with outer layers of pre-coated galvanized steel (0.4–0.8mm) or stainless steel (SS304), and a rigid polyurethane (PU) or PIR foam core (50–250mm thickness).
Thermal Insulation: Low thermal conductivity (0.024W/m·K) ensures superior energy efficiency.
Cam Lock System: Quick-connect mechanism for fast, airtight assembly without additional sealing.
Durability: Corrosion-resistant metal facing, moisture-proof foam core, and long service life (15+ years).
Fire Resistance: PIR variant offers improved flame retardancy (up to B1 rating).
Customization: Available in widths up to 1183mm, lengths up to 13.5m, with various surface finishes.
Products Case
Food Industry: Cold storage (0°C to +10°C), frozen warehouses (-18°C to -25°C), and ultra-low temp freezers (-30°C to -60°C).
Pharmaceuticals: Vaccine storage (2–8°C), blood plasma freezing (-30°C), and temperature-controlled labs.
Industrial Use: Chemical storage, electronics manufacturing (cleanrooms), and floral preservation.
Retail & Logistics: Supermarket chillers, distribution hubs, and modular cold rooms.

What is the delivery time and payment method of Polyurethane Foam Insulation Sheets?
Deliver time always 15-20 days, and advance payment TT 30% ,balance payment TT 70% before delivery.
Here are the reasons why our cold storage roof panels are the best choice for your project:
✔ Lower thermal conductivity (0.022-0.025 W/m·K vs. PU's 0.023-0.028)
✔ Higher fire resistance (B1/A-class vs. PU's B2 or EPS's flammable rating)
✔ Better moisture resistance (closed-cell structure prevents water absorption)
