Fire-Retardant B1-Grade PIR Cold Storage Panels for Low-Temperature Freezer (-18°C) 100mm

Product Summary

Our B1-grade PIR cold storage panels (model: JSGREEN001) are engineered for low-temperature freezer applications down to -18°C. With a 100mm thick rigid polyurethane/PIR core and double-sided 0.5mm steel sheets, these panels deliver excellent thermal insulation (thermal conductivity ≤0.024 W/(m·K)) and meet B1 fire-retardant standards. They are widely used in food processing, cold chain logistics, and pharmaceutical storage where strict temperature control and fire safety are required.

Key Selling Points

• Superior Thermal Insulation: Thermal conductivity ≤0.024 W/(m·K) reduces energy consumption by over 30% compared to conventional insulation, ensuring stable -18°C freezer temperatures.
• B1 Fire-Retardant Core: Complies with B1 fire rating (difficult to ignite) for enhanced safety in food and pharmaceutical facilities.
• High Load-Bearing Capacity: Double-sided 0.5mm color steel sheets combined with precision foaming provide excellent flatness and load capacity, supporting heavy equipment.
• Modular Design for Fast Installation: Standardized panels with effective width of 960mm/1100mm increase on-site installation speed by 30%, reducing project timelines.
• Seamless Joints & Air-Tightness: Precision cam-lock joint system prevents cold air leakage and condensation, maintaining temperature stability.

Technical Specifications

Models and Options

Available in thicknesses of 50mm, 75mm, 100mm, and 120mm for different temperature requirements. The 100mm version is recommended for deep freezers at -18°C or lower. Width options: 960mm or 1100mm. Fire rating options: B1 (standard) or B2 (upon request).

Materials and Structure

Rigid polyurethane (PU) or polyisocyanurate (PIR) foam core bonded to two layers of 0.5mm thick color steel sheets. The closed-cell foam structure provides moisture resistance (relative humidity up to 90%) and prevents water vapor penetration. Panels feature a tongue-and-groove joint with built-in gaskets for air-tight sealing. Optional aluminum foil facing for clean-room applications.

Applications

Ideal for low-temperature freezers in food & beverage processing (meat, seafood, dairy), pharmaceutical cold storage (vaccines, medicines), and cold chain logistics centers. Suitable for harsh environments including coastal high-salt spray areas and high-humidity conditions (≤90% RH).

Customization

• Panel dimensions: length, width, and thickness can be customized per project requirements.
• Surface finish: color steel sheet colors available (white, gray, blue, etc.).
• Additional options: stainless steel face for hygiene-sensitive areas, special flange profiles for quick assembly.
• Fire rating: B1 or B2 grade core can be selected.

Case Study

Food Processing Plant (Australia & Vietnam): Supplied 5,000 sqm of B1 PIR panels (100mm thick) for a low-temperature freezer (-18°C) and chiller room (0-4°C). The panels achieved precise temperature control, seamless joints preventing cold air leakage, and passed GSP certification. The modular design reduced installation time by 30%, meeting a tight project deadline.
