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.

More About PIR/PUR Cam Lock Sandwich Panel
The core material, polyurethane, is a thermoset polymer that expands to form a dense, closed-cell structure. This traps air, providing excellent insulation by minimizing heat transfer.
-
🌡️
High Thermal Insulation Value
Minimizes heat transfer with a low thermal conductivity coefficient (λ ≈ 0.023–0.025 W/m·K).
-
🔒
Cam Lock Design
Enables fast, secure connection and tight seals to minimize air leakage.
-
⚖️
Lightweight
Strong yet easy to handle, reducing overall building structural load.
-
💧
Moisture-proof
Closed-cell structure resists moisture and prevents mold growth.
