Product Description

Products Description

Polyurethane cam lock sandwich panels consist of a core made of polyurethane foam, sandwiched between two outer layers, which are typically made from sheet metal such as galvanized steel or aluminum. Panels are available in a variety of thicknesses, typically 100mm to 200mm, depending on specific insulation requirements.

Core Benefits of PUR/PU Panels

Polyurethane is a thermoset polymer with a dense, closed-cell structure that traps air, providing industry-leading insulation for cold storage facilities.

🌡️

High Thermal Insulation Value Thermal conductivity coefficient (λ) of approximately 0.023–0.025 W/m·K, minimizing heat transfer effectively.

🔐

Secure Cam Lock Design Enables fast, secure connection for a tight seal, minimizing air leakage and enhancing thermal efficiency.

⚖️

Lightweight Structure Strong yet easy to handle, reducing the overall structural load and simplifying the installation process.

💧

Superior Moisture Resistance The closed-cell structure prevents moisture absorption and mold growth, essential for high-humidity environments.
