Bingyan PIR Cold Storage Panels

High-Efficiency Thermal Insulation Solution for Professional Cold Storage

Our PIR (Polyisocyanurate) cold storage panels are high-performance thermal insulation sandwich panels specially designed for commercial and industrial cold storage applications. Adopting a metal panel + PIR core + metal panel sandwich structure, they are molded via the pentane foaming process based on high-quality polyurethane raw materials from Yantai Wanhua. These panels lead the industry in thermal insulation, fire resistance, moistureproofing, and structural strength.

Product Overview

Core Thermal Insulation Performance

The PIR core features an ultra-low thermal conductivity of ≤0.024W/m·k and a closed-cell rate of ≥95%, effectively blocking heat and cold transfer and significantly reducing the refrigeration energy consumption of cold storage. It provides a stable low-temperature environment for the food, pharmaceutical, cold chain logistics and other industries.

Safety Protection Grade

The product achieves the GB B1 grade flame-retardant standard with an oxygen index of ≥30%. It only carbonizes without dripping when exposed to fire. Combined with waterproof and anti-corrosion design, it can adapt to harsh working conditions such as humidity, low temperature and high salt spray, greatly improving the overall safety level of cold storage.

Construction & Operation Advantages

Standardized panels with a width of 1120mm matched with special connectors enable rapid modular assembly, allowing the construction of the enclosure structure for a 100㎡ cold storage within 2 hours. The fully automatic production line ensures product consistency with a service life of 15-20 years, significantly reducing later maintenance costs.

Environmental Protection & Compliance

The pentane foaming technology with low global warming potential is adopted, in line with the international environmental protection trend. Meanwhile, all performance indicators meet national and industrial standards such as GB50072-2021 and JB/T 6527-2006, making the panels directly applicable to export and various high-end cold chain projects.

Product Overview

Horizontal & Vertical Installation Steps

• Conduct base treatment with waterproof membrane and SBS cushion layer

• Fix galvanized L-shaped or U-shaped positioning parts with expansion bolts

• Lay the sealant base

• Pre-install panel joint sealant (double-sided groove sealant + middle polyurethane spraying)

• Install vertical wall panels

• Install wall purlins, C-section steel and quick mushroom head rivets when the length exceeds 6 meters

Ceiling Panel Installation Method

• Determine the length and hoisting direction of ceiling panels according to the main building girders (ceiling panel joints are parallel to the main building girders)

• Pre-install hanging beam structural parts: 6# channel steel and fixed hanging beams, connected to C-shaped keels with M12 hanging screws

• Hoist the thermal insulation ceiling panels

• Adjust the length of hanging screws

• Spray polyurethane foam at the main joints, use PVC casing for foaming to break the cold bridge, and trim the color steel flanging parts
