Fire-Retardant B2-Grade PIR Cold Storage Panels for Chiller Room (0-4°C) 50mm

Product Summary

Our B2-grade PIR cold storage panels (model: JSGREEN001) are optimized for chiller rooms operating at 0-4°C. With a 50mm thick rigid polyurethane/PIR core and double-sided 0.5mm steel sheets, these panels provide efficient thermal insulation (thermal conductivity ≤0.024 W/(m·K)) while meeting B2 fire-retardant standards for general industrial applications. They are widely used in food processing plants, supermarket distribution centers, and agricultural preservation facilities.

Key Selling Points

• Cost-Effective Insulation: Thermal conductivity ≤0.024 W/(m·K) delivers energy savings of over 30% at a lower cost per square meter compared to thicker panels, ideal for chiller rooms.
• B2 Fire-Retardant Core: Complies with B2 fire rating (normal flammability) suitable for most commercial and industrial applications.
• Moisture Resistance: Closed-cell PIR foam structure prevents water vapor penetration and condensation, even in high-humidity chiller environments.
• Fast Installation: Modular panels with effective width of 960mm/1100mm reduce on-site assembly time by 30% compared to traditional construction.
• Versatile Applications: Suitable for food, beverage, agricultural, and general cold storage where 0-4°C temperature control is needed.

Technical Specifications

Models and Options

This variant is specifically designed with 50mm thickness for chiller room applications (0-4°C). Other thicknesses (75mm, 100mm) are available for different temperature zones. Fire rating B1 can be selected for enhanced safety. Width options: 960mm or 1100mm.

Materials and Structure

Rigid PIR foam core bonded to two layers of 0.5mm color steel sheets. The closed-cell structure offers excellent moisture resistance (up to 90% RH) and prevents vapor ingress. Panels feature a tongue-and-groove joint with pre-fitted EPDM gaskets for air-tight sealing. Optional aluminum foil or stainless steel facing for specific hygiene requirements.

Applications

Ideal for chiller rooms in food & beverage processing (meat, dairy, produce), pharmaceutical cool storage, supermarket cold rooms, agricultural pre-cooling facilities, and cold chain logistics distribution centers. Suitable for environments with relative humidity up to 90%.

Customization

• Panel dimensions: length, width, and thickness tailored to project needs.
• Surface finish: various color steel sheet colors available.
• Additional options: cam-lock or tongue-and-groove joint systems, special profiles for easy assembly.
• Fire rating: B2 standard; B1 upgrade available.

Case Study

3PL Cold Chain Logistics Center (Australia): Supplied 12,000 sqm of B2 PIR panels (50mm thick) for a multi-temperature distribution center (frozen, chilled, ambient). The panels were delivered on schedule and installed easily. The modular design improved cargo turnover efficiency and maintained stable temperatures across different zones.
