Modular cold room panels combine rigid Polyurethane (PUR) or Polyisocyanurate (PIR) foam insulation with metal cladding sheets to create prefabricated building components for temperature-controlled environments. The foam core, typically 40-50 kg/m³ density, is CFC-free and expanded using environment-friendly blowing agents like n-penthane. Metal claddings use pre-painted galvanized steel or stainless steel for corrosion resistance and hygiene.
Standard thicknesses range from 50mm to 200mm, with widths of 960mm, 1000mm, or 1120mm. The foam core achieves thermal conductivity values of 0.020-0.024 W/(m·K), delivering R-values of 5-8.8 per inch. Metal cladding thickness varies from 0.4mm to 0.8mm, available in Resistance Against Lightness (RAL) chart colors. Panels feature interlocking tongue-and-groove joints with cam-lock fasteners for airtight connections.
Applications span food storage, pharmaceutical facilities, and industrial environments requiring precise thermal management. The panels serve as walls, partitions, ceilings, and roofing in refrigerated warehouses, food processing plants, blast freezers, and cold chain logistics vehicles. The bacteriostatic surface treatment inhibits bacterial growth, supporting food safety requirements.
Installation utilizes the cam-lock system for quick assembly – panels align and an Allen wrench engages the fastener, creating secure connections. The modular design enables flexible configurations and supports high load-bearing capacity for direct equipment mounting. Panels meet international standards including Conformité Européenne (CE), Factory Mutual (FM), and Food and Drug Administration (FDA) certifications.

Cold Room Panel Refrigeration & Thermal Insulation Engineering Guide
Cold room insulated sandwich panels are critical thermal envelope components engineered for commercial walk-in coolers, industrial cold storage logistics, pharmaceutical freezers, and blast freezing tunnels. Formulated with high-density closed-cell PIR/PUR foam ($\lambda pprox 0.019 – 0.022$ W/m·K) and integrated Cam-Lock or tongue-and-groove joint systems, these panels maintain stable sub-zero temperatures down to -40°C while minimizing compressor energy consumption.
💡 Pro Tip: Integrated Cam-Lock Hooks & Dual Butyl Thermal Seals
At RaxPanel, our modular cold room panels feature factory-embedded eccentric metal Cam-Locks. Turning a hex wrench draws panel edges together under high mechanical tension, compressing dual internal elastomeric gaskets to form a vapor-tight seal that eliminates frost formation and cold bridge thermal leakage.

1. How to Select Panel Thickness Based on Operating Temperature Ranges?
Selecting incorrect panel thickness leads to continuous compressor overload and ice formation on joint seams. RaxPanel thermal thickness guidelines include:
2. Cam-Lock Modular vs Continuous Tongue-and-Groove Logistics Systems
Modular walk-in coolers utilize internal Cam-Locks for rapid hex-wrench assembly without wet sealants. Large-scale refrigerated distribution warehouses utilize continuous tongue-and-groove PIR panels for long structural spans up to 12 meters.
3. Cold Room Sliding Doors and Floor Anti-Heave Systems
🚪 Sub-Zero Door & Floor Protection:
- Heated Door Frame Gaskets: Heavy-duty sliding/hinged cold room doors integrate perimeter heating wires to prevent rubber gasket freezing.
- Under-Floor Frost Heave Prevention: Freezers built directly on soil integrate ventilation ducts or electric heating mats below the insulation slab to prevent ground frost expansion.
4. Where Are Cold Room Panels Most Commonly Installed?
🥦 Cold Chain Logistics & Distribution Hubs
High-bay automated cold storage warehouses storing fresh produce, meat, and frozen foods.
💉 Pharmaceutical & Vaccine Storage Facilities
Temperature-controlled GSP/GMP certified cold rooms maintaining 2°C to 8°C stability.
5. USDA & HACCP Hygiene Compliance for Surface Facings
Steel facings feature food-safe white antibacterial polyester coating or Grade 304 stainless steel. Non-porous surfaces withstand daily high-pressure washdowns without chemical degradation.
Frequently Asked Questions (FAQS)
1. What cold room panel thickness is needed for a -20°C freezer room?
A 120mm to 150mm PIR panel is recommended for -20°C freezer rooms to achieve optimal thermal U-values (U ≈ 0.15 W/m²K) and prevent compressor overload.
2. How does the Cam-Lock system simplify walk-in cooler assembly?
Embedded eccentric Cam-Locks pull adjacent panels tight using an Allen key, forming a vapor-tight seal without needing external screws or on-site welding.
3. What is the thermal conductivity (λ) of RaxPanel cold room foam cores?
Our closed-cell PIR/PUR foam achieves a thermal conductivity coefficient of 0.019 to 0.022 W/m·K for maximum thermal insulation.
4. Why do cold room door frames require heating cables?
Door perimeter heating cables prevent ambient moisture condensation from freezing door gaskets shut against sub-zero freezer frames.
5. Are RaxPanel cold room panels food-grade USDA compliant?
Yes. Pre-painted steel skins use food-safe anti-bacterial polyester coatings that meet USDA, FDA, and HACCP sanitation standards.
6. How is floor frost heave prevented under freezer slabs?
Under-floor XPS/PIR insulation is installed above sub-slab ventilation pipes or electrical heating cables to prevent soil moisture freezing and expanding.
7. Can modular cold room panels be dismantled and relocated?
Yes. Cam-Lock joined panels can be unlocked with a hex wrench, dismantled without damage, and reassembled or expanded at a new location.
