More About PIR/PUR Cam Lock Sandwich Panel
The core material, polyurethane, is a thermoset polymer that expands during manufacturing to form a dense, closed-cell structure. This structure traps air, providing excellent insulation by minimizing heat transfer.
  • 🌡️ High Thermal Insulation Value: Thermal conductivity coefficient (λ) of approximately 0.023–0.025 W/m·K.
  • 🔐 Cam Lock Design: Enables fast and secure panel connection, ensuring a tight seal and minimizing air leakage.
  • ⚖️ Lightweight: Easy to handle and install, reducing overall structural load on the building.
  • 💧 Moisture-Proof: Closed-cell structure resists moisture absorption and prevents mold growth.
Frequently Asked Questions
What thicknesses are available for PUR cam lock sandwich panels?
PUR cam lock sandwich panels are available in thicknesses of 100mm, 120mm, 150mm, and 200mm. Custom thicknesses can also be arranged based on project requirements.
What is the heat transfer coefficient of these sandwich panels?
The heat transfer coefficient (Ud,s) of polyurethane core sandwich panels is ≤0.024 W/[m·K], making them highly efficient insulators for temperature-controlled environments.
What surface materials can I choose?
Available materials include PPGI (Pre-painted Galvanized Iron), Stainless Steel (SUS304/SUS201), Embossed Aluminum, and various alloys (Zinc, Magnesium, Titanium). Surface thickness ranges from 0.3mm to 0.8mm.
What are the benefits of the cam lock mechanism?
The cam lock mechanism creates a tight, secure seal between panels that minimizes air leakage and heat transfer, ensuring consistent low temperatures in cold storage facilities.
What are the standard dimensions of the panels?
Panels come in effective widths of 920mm, 960mm, and 1000mm, with a maximum length of 10 meters.
Are the panels resistant to moisture and mold?
Yes, the closed-cell structure of the polyurethane foam core makes it highly resistant to moisture absorption and prevents the growth of mold.
