What it is
Industrial cold rooms are controlled-temperature built environments used for storage, processing or distribution of temperature-sensitive products — refrigerated foods (0 to 5°C), frozen foods (−18 to −25°C), ultra-cold products (below −40°C for ice cream, certain pharmaceuticals, blood derivatives), controlled-atmosphere rooms (fruits, wines), refrigerated environments for chemical and pharmaceutical industry. Construction is executed with cold-storage-specific sandwich panels — with thicker PIR foam (75–200 mm depending on temperature), enhanced vapor barriers, heavier metal faces, and specific sealing systems.
The difference between a cold storage panel and a conventional industrial panel is not just thickness. The panel is designed as an integrated thermal + moisture + structural system: the PIR core has specific formulation for stability in negative temperatures, the joint between panels has cold-specific sealing profiles, the outer faces typically have vapor-blocking coating (moisture migration is the main cause of cold room failure over time). Floors, ceilings, columns, doors — each is designed specifically for the operation of the cold room.
Commercial cold rooms cover ranges from 50 m² (small food-service businesses) to 100,000+ m² (large logistics centers, industrial-scale cold storage distributors). The largest global players include Lineage Logistics, Americold, United States Cold Storage, NewCold, Agro Merchants. In Brazil, relevant players include Super Frio, Localfrio, Cold Logistic.

Value proposition
Cold storage insulation comparison:
| Core material | Lambda (W/m·K) | Typical service life | Fire reaction |
|---|---|---|---|
| PIR (40 kg/m³) | 0.021–0.023 | 25–40 years | Euroclass B-s1,d0 |
| PUR/PIR (38–42 kg/m³) | 0.022–0.024 | 25–35 years | Euroclass B-s2,d0 to C-s2,d0 |
| Pure PUR (38–42 kg/m³) | 0.024–0.026 | 20–30 years | Euroclass D-s2,d0 |
| High-density mineral wool | 0.035–0.040 | 20–30 years | Euroclass A1 |
| EPS | 0.036–0.040 | 15–25 years | Euroclass E |
Operational ROI for a frozen-goods cold room (industry benchmark):
A 2,000 m² frozen-goods room operating at −25°C with 150 mm sandwich panels:
- With PIR lambda 0.022: estimated refrigeration consumption ~180 kWh/m²/year
- With PUR/PIR lambda 0.026: estimated consumption ~210 kWh/m²/year
- Differential: ~60,000 kWh/year × USD 0.14/kWh = USD 8,400/year savings with the PIR system
Over 20 years of operation, cumulative savings with the better-performing system can reach USD 300,000–400,000 — far exceeding the initial cost differential between the two systems.
Additional end-customer arguments:
- Compliance with certifications: cold storage for animal protein export requires international certifications that specify PU systems with documented performance
- Construction speed: cold storage rooms with prefabricated panels are assembled in weeks vs. months of traditional construction
- Ease of expansion: modularity allows room expansion as the business grows
- Residual value: quality sandwich panels maintain considerable residual value in case of relocation or sale
