Cold Room Panel

Cold room panels combine rigid polyurethane (PUR) or polyisocyanurate (PIR) foam cores with outer cladding sheets of pre-painted galvanized steel (PPGI), stainless steel, or embossed aluminum. The CFC-free foam, injected under high pressure at densities of 40-45 kg/m³, achieves thermal conductivity of 0.022-0.024 W/(m·K) and compressive strength above 160 kPa. Standard thicknesses range from 50mm to 200mm, with widths of 960mm, 1000mm, or 1120mm and customizable lengths up to 12 meters.

The interlocking tongue and groove joint system creates thermal bridge-free connections, often enhanced with cam-lock fasteners for airtight sealing. This design maintains consistent temperatures from -45°C to +10°C while providing R-values between 5 and 8.8 per inch of thickness. The panels resist moisture, corrosion, and chemicals, with fire ratings of B2 for PUR and B1 for PIR cores.

Applications include food storage, pharmaceutical facilities, industrial warehouses, and processing plants. Panels accommodate refrigeration equipment mounting and support complex multi-room configurations. Customization options include RAL colors, surface finishes from flat to corrugated, and cladding thickness from 0.4mm to 1.0mm to meet hygiene standards including EC/USDA requirements with antibacterial coatings.

Cold Room Ceiling Panel

A structural insulated panel engineered for horizontal spanning capabilities with a high-density polyurethane foam core. It is characterized by its excellent thermal resistance and a profile designed for suspension, supporting integrated components while maintaining a continuous, airtight, and vapor-proof ceiling barrier.

Cold Room Door Panel

An insulated door system combining a high-density foam core with durable metal cladding and a robust gasket sealing system. It is defined by its ability to create a hermetic seal, featuring heavy-duty hardware and an integrated thermal break to prevent energy loss.

Cold Room Floor Panel

A high-load bearing insulated panel featuring a high-density, high-compressive-strength polyurethane foam core with reinforced surface layers. It is designed to withstand significant static and dynamic loads, providing a durable, waterproof, and thermally stable base with optional non-slip finishes.

Cold Room Wall Panel

A modular, self-supporting insulated panel used for vertical construction, featuring a rigid polyurethane foam core. It is defined by its tongue-and-groove edges and an integrated cam-lock fastening system, which ensures rapid assembly, structural stability, and airtight, thermal bridge-free joints.

Modular Cold Room Panel

Modular cold room panels are insulated sandwich wall and roof sections, typically PU/PIR foam between metal skins, joined by cam-lock or tongue-and-groove edges for fast assembly, airtight sealing, and energy-efficient temperature-controlled storage rooms.

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:

Cold Storage Zone	Target Temperature Range	Recommended Panel Thickness & U-Value
Chiller / Processing Rooms	+2°C to +10°C	75mm – 100mm PIR Panel (U ≈ 0.22 W/m²K)
Commercial Freezer Storage	-18°C to -25°C	120mm – 150mm PIR Panel (U ≈ 0.15 W/m²K)
Blast Freezing Tunnels	-35°C to -40°C	150mm – 200mm PIR Panel (U ≤ 0.11 W/m²K)
Under-Floor Insulation	Sub-Zero Freezer Floors	XPS / PIR Under-Slab Boards + Floor Heating Mat (Anti-Heave)

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.
