In a cold chain storage project in the United States, the 50mm thick PU sandwich panel provided by Yirong sandwich panel supplier has become the preferred material for cold storage construction due to its excellent comprehensive performance.

Efficient thermal insulation, energy saving and consumption reduction
Yirong 50mm PU panel adopts high-density closed-cell foaming process, with a thermal conductivity as low as 0.022W/(m·K), which is only 1/3 of traditional rock wool boards. Although the thickness is only 50mm, its thermal insulation performance is sufficient to meet the needs of conventional cold storage from -18°C to +4°C, effectively reducing the loss of cooling capacity. It has been calculated that compared with traditional 100mm thick rock wool boards, the operating energy consumption of this cold storage can be reduced by more than 30%, significantly saving long-term electricity expenses.
Lightweight and structural adaptability
The 50mm thickness significantly reduces the self-weight of the plate and reduces the building load. It is especially suitable for renovation projects or warehouses with limited floor load-bearing. At the same time, the modular design supports rapid assembly, shortens the construction period, and meets the high requirements of American customers for construction efficiency.

Precise temperature control and anti-condensation
The closed cell rate of PU panel exceeds 95%, the water absorption rate is extremely low, and with the seamless splicing process, the cold bridge effect is completely eliminated. The temperature difference within the warehouse can be controlled within ±0.5°C to ensure stable quality of food, medicine and other goods while avoiding the risk of mildew caused by condensation on the inner wall.
Environmental protection and durability
The board complies with the American ASTM E84 fire protection standard (Class A flame retardant) and does not contain harmful substances such as Freon. Surface coating treatment enhances corrosion resistance and has a service life of more than 20 years, reducing maintenance costs.

Customer comments: "Yirong's PU cold storage panels have achieved thermal insulation effects far beyond expectations and are an ideal choice for our cold chain upgrade."
