2 Product Features
These panels consist of two sturdy metal sheets encasing a thick insulating layer, often made from high-quality materials like polyurethane foam. This unique design delivers outstanding thermal insulation, making them perfect for keeping cold storage spaces consistently chilled. Unlike traditional building methods, sandwich panels are lightweight yet strong, allowing for quick assembly without sacrificing durability.
What sets these panels apart is their streamlined installation process. Delivered in pre-cut sections, they fit together effortlessly with tight, interlocking joints. This creates a solid barrier against air leaks and moisture, critical for preserving perishable items like food or pharmaceuticals. For anyone constructing a cold storage facility—say, a warehouse for fresh produce—these panels reduce setup time and labor costs significantly. Their energy-saving properties also stand out, as the insulation minimizes heat transfer, cutting down on refrigeration expenses month after month.
Durability is another key benefit. Built to endure harsh conditions, sandwich panels resist wear and tear, ensuring your cold storage room stays functional for years. They’re also versatile, suitable for new builds or retrofitting older structures. With a clean, professional finish, they enhance the facility’s appearance while meeting strict hygiene standards. In short, installing sandwich panels brings together speed, efficiency, and long-term value, making them a top choice for cold storage projects aiming for performance and cost savings.

5 Application Areas of Cold Storage Panels
Cold storage panels are engineered to meet the rigorous demands of industries requiring controlled temperature environments. From food processing to pharmaceuticals, these panels ensure optimal preservation, safety, and efficiency across critical sectors:
1. Food Processing & Rapid Freezing
Ideal for blast freezing (-40°C to -18°C), our panels maintain consistent ultra-low temperatures to lock in freshness for seafood, meats, and ready-to-eat meals. Anti-bacterial surfaces and airtight joints comply with HACCP and ISO 22000 standards.
2. Dairy & Perishable Storage
Designed for dairy products (2°C to 6°C), the panels prevent bacterial growth with hygienic, easy-to-clean finishes while minimizing energy consumption.
3. Pharmaceutical & Biotech Facilities
Temperature-stable panels (2°C to 8°C) ensure integrity of vaccines, medicines, and biologics. Fire-rated cores (EN 13501-1) and moisture-proof seals meet GMP and WHO guidelines.
4. Cold Chain Logistics
Lightweight yet durable panels are tailored for refrigerated trucks and containers, offering shock resistance and thermal efficiency (-25°C) to protect goods during transit.
5. Commercial Indoor Cold Rooms
Customizable sizes and finishes suit supermarkets, restaurants, and warehouses, balancing cost-effectiveness with robust insulation (R-value up to 6.5 per inch).
