Cold Room Panel | Polyurethane & Mineral Wool Insulation Boards

Prefabricated insulated sandwich panels provide precision thermal envelope solutions for industrial and commercial temperature-controlled environments. These panels consist of dual pre-painted metal facings structurally bonded to a high-density insulating core, engineered to maintain internal thermal gradients from +15°C down to -40°C.

Primary Function

Thermal insulation, vapor barrier integrity, and structural enclosure for cold stores, cleanrooms, and food processing facilities.

Target Sectors

Cold storage general contractors, mechanical installation contractors, industrial refrigeration system integrators, and modular facility builders.

Core Value Proposition

Low thermal transmittance (U-value), zero air leakage via precision eccentric cam-lock or tongue-and-groove joints, and certified fire safety ratings compliant with international building codes.

Manufacturing Baseline

Produced via continuous high-pressure foaming lines and automated multi-layer roll-forming machines, ensuring consistent core density distribution and precise dimensional tolerances (±1.0 mm).

Product Types & Selection

Selecting the correct panel type depends on operating temperature, fire compliance codes, and structural load requirements.

Polyurethane (PUR / PIR) Panels

Application Range: Standard cold rooms, refrigerated warehouses, and frozen food storage (+5°C to -40°C).
Selection Criteria:
Select 100 mm thickness for positive temperature rooms (0°C to +15°C).
Select 150 mm to 200 mm thickness for low-temperature freezers (-20°C to -40°C).
Core Characteristics: Closed-cell ratio ≥ 95%, offering minimal moisture absorption and optimal thermal resistance.

Rigid Mineral Wool Insulation Panels

Application Range: Firewalls, exterior partition walls requiring strict non-combustible ratings, and high-temperature processing zones.
Selection Criteria: Deployed where local building regulations mandate Class A1 non-combustible materials or acoustic isolation alongside thermal break requirements.
Core Characteristics: High melting point (> 1000°C), superior dimensional stability under thermal shock.

Applications & Compatibility

01.

Walk-in Freezers & Coolers

Interlocking cam-lock joints enable rapid assembly and disassembly for commercial refrigeration units.

02.

Industrial Cold Storage Warehouses

Large-span structural wall and ceiling panels engineered to withstand positive and negative wind pressures as well as hanging evaporator loads.

03.

Food Processing & Cleanrooms

Flush-joint configurations combined with anti-bacterial food-grade coatings (PE, PVDF, or Silicon Polyester) resistant to frequent chemical washdowns.

04.

System Compatibility

Fully compatible with standard refrigeration doors (hinged, sliding, or overhead), structural steel framing, and extruded aluminum ceiling suspension profiles.

Customization & Supply

Dimensional Customization

Panel lengths cut to exact project specifications up to 16,000 mm to minimize on-site cutting and waste.

Facings & Colors

Custom steel gauges (0.4 mm to 0.8 mm), surface profiles (micro-ribbed, fluted, or flat), and RAL color matching available upon request.

OEM / ODM Services

Private labeling, protective film branding, and project-specific packaging specifications for regional distributors.

Production Capacity & Supply Chain

Continuous production lines yield an average output of 10,000 m² per day. Standard lead time is 14 to 21 days for full container loads (FCL), packaged in reinforced timber crates designed for ocean freight.

Quality Control & Support

In-House Inspection

Raw steel coils undergo thickness, tensile strength, and zinc-coating verification prior to roll-forming. Foaming reaction parameters (pressure, temperature, and index) are monitored in real-time on the continuous lamination line.

Finished Product Testing

Random samples undergo destructive testing for peel strength, core density, and compressive strength per batch.

Documentation Package

Each shipment includes Mill Test Certificates (MTC), CE conformity declarations, thermal performance test reports, and detailed installation shop drawings.

Technical Support

Engineering assistance is available for panel layout optimization, thermal bridge calculation, and installation guidance.

Frequently Asked Questions

Q: What is the difference between PUR and PIR core materials for cold rooms?

A: PIR (Polyisocyanurate) features an adjusted chemical formulation that provides enhanced fire resistance, achieving a B-s1, d0 rating, making it the preferred choice for commercial and industrial buildings requiring strict fire safety compliance.

Q: How do cam-lock joints prevent air leakage between panels?

A: Eccentric cam-locks pull adjacent panels tightly together during installation. When combined with factory-applied polyurethane joint sealants, this mechanical connection forms an airtight, vapor-tight seal that eliminates thermal bridging.

Q: What is the maximum unsupported span for ceiling panels?

A: Maximum spans depend on panel thickness, density, and distributed dead loads (such as suspended evaporators). Typically, a 150 mm thick PUR panel can span up to 5.5 meters without intermediate structural support under standard cold room loads.

Q: Are these panels suitable for corrosive environments like seafood processing plants?

A: Yes. For corrosive or high-humidity environments, we supply panels with stainless steel facings or specialized protective coatings (such as PVC plastisol or high-durability PVDF) to prevent chemical degradation.

Q: How are panels packaged for international ocean freight?

A: Panels are stacked with protective foam interleaves, wrapped in moisture-resistant film, secured with edge protectors, and loaded onto heavy-duty wooden skids secured inside 40-foot high-cube containers.

Q: What minimum order quantity (MOQ) is required for custom lengths or non-standard RAL colors?

A: The standard MOQ for custom lengths is 300 m² per specification. For custom RAL color coatings on steel facings, a minimum order of 1,000 m² applies to accommodate coil coating runs.
