2 Product Features
Elevate your cold storage solutions with PU/PIR Cold Room Sandwich Panels, designed to deliver top-tier thermal insulation and durability. Boasting a thermal conductivity of 0.019-0.022 W/m·K—the lowest among practical insulation materials—these panels ensure maximum energy efficiency. Crafted with high-pressure continuous foaming technology, they feature a uniform foam structure with a cell density of 200,000 per cm³ and a 97% closed-cell rate, minimizing water vapor penetration for long-lasting performance. This makes them a standout choice for maintaining consistent temperatures in cold chain facilities.
Beyond insulation, these panels excel in fire resistance, utilizing polyurethane foam that forms a protective coking layer when exposed to flames, avoiding the melting or dripping seen in EPS or XPS. Paired with metal facings, they achieve a B1 fire rating (national standard 8624-2012), enhancing safety. The innovative pentane technology uses eco-friendly, non-fluorinated materials, aligning with global ozone protection standards while reducing environmental impact. Additionally, the proprietary airtight technology eliminates cold steam bridges, ensuring seamless integration and superior airtightness—perfect for air-conditioned warehouses.
For sustainability and cost savings, these panels reduce energy consumption by up to 30%, thanks to their advanced insulation system. Hygienic and resistant to bacteria, they meet the strict demands of the cold chain industry. Prefabricated for easy, rapid installation, they shorten construction timelines and cut labor costs, offering a reliable, green solution for modern cold storage needs.

Selecting cold storage sandwich panels, thickness is the key to mastering temperature control. Our panels are crafted to match specific temperature differences between interior and exterior environments, ensuring your cold storage operates efficiently. A 100mm thick panel supports a 30°C differential, ideal for -15°C conditions, with wall heights up to 5 meters and roof spans of 4.45 meters. For harsher demands, a 125mm panel handles 35°C differences, maintaining -20°C, while a 150mm option tackles 50°C gaps for -25°C storage. Pushing further, 175mm panels manage 65°C variances for -30°C, and the robust 200mm thickness excels at 75°C differences, perfect for -40°C extremes.
Built to endure internal-external pressure shifts and contraction stresses, these panels thrive under a heat flow of 8-10 W/m². However, exceeding listed heights or lengths, or facing wind loads, requires additional supporters to maintain stability. Our cold storage sandwich panels blend durability with energy efficiency, offering tailored insulation solutions. Optimize your facility’s performance by choosing the right thickness for your temperature needs—whether it’s chilled goods or deep-freeze applications, we’ve got you covered with reliable, high-performance panels.
