Cold storage facilities — chiller rooms, frozen food warehouses, pharmaceutical cold chain, and blast freezers — demand the highest insulation performance of any building type. Insulated aluminum panels with thick PIR or PUR cores maintain stable internal temperatures while resisting condensation and corrosion.
Thickness Selection by Temperature
| Application | Internal temp | Panel thickness | U-value |
|---|---|---|---|
| Air-conditioned cool room | +12 to +18°C | 100mm PIR | 0.22 |
| Chiller room | 0 to +4°C | 150mm PIR | 0.15 |
| Frozen storage | -18 to -25°C | 200mm PIR | 0.11 |
| Blast freezer | -35 to -40°C | 200mm+ PIR | 0.11 or lower |
Cold Storage Panel Features
- Food-grade smooth face — easy to clean, meets hygiene requirements
- Tongue-and-groove joints with cam locks — airtight seal preventing thermal bridging and condensation
- High-density PIR core (≥42 kg/m³) — dimensional stability at sub-zero temperatures
- Custom lengths to 12m — minimizes joints in long cold room walls
FOB Tianjin pricing for 150-200mm cold storage panels: USD 16-27/m². Full export documentation including SGS inspection available.

WhatsApp QuoteInsulated aluminum Great Wall panels are built for cold storage, blast freezers and chill rooms. Food-grade aluminum faces resist washdown and corrosion, and thick PU/PIR cores hold sub-zero setpoints with low energy loss.
Hold −18 to −30°C efficiently
Cold storage lives or dies on the envelope. A 100mm core suits chill rooms (0–5°C), 150mm for −18°C freezers, and 200mm for −30°C blast freezers. Higher density (42–45 kg/m³) core keeps thermal performance stable over the years.
Food-grade, corrosion-proof, washdown-ready
Aluminum faces are food-grade and tolerate chlorine-based disinfectants and high-pressure washdown that corrode painted steel. Tongue-and-groove joints eliminate the thermal bridges that cause condensation and ice build-up.
Matched insulated doors and details
Hinged and sliding insulated cold-room doors, matched to panel thickness, and all closure trims ship in the same container so the room seals correctly.
Frequently asked questions
What thickness for a −18°C freezer? 150mm PU/PIR; use 200mm for −30°C blast freezers and 100mm for chill rooms.
Are the panels food-grade? Yes — aluminum faces are food-grade and washdown/disinfectant resistant.
Do you supply cold-room doors? Yes — hinged and sliding insulated doors ship in the same container.
What core density? 42–45 kg/m³ PU/PIR for stable sub-zero performance.
