Our high-performance PIR Panels represent the gold standard for advanced thermal insulation in modern cold storage facilities. They address the strict climate control needs of demanding industrial environments. These insulated panels deliver outstanding thermal efficiency, structural integrity, and long-term durability. By choosing Shanghai Heleng, your project benefits from reduced thermal bridging and lower operational energy costs. We also ensure reliable fire safety across diverse cold chain applications.
These specialized sandwich panels provide an impermeable barrier against heat transfer and moisture infiltration. Built with a continuous double-belt manufacturing process, each unit features a high-density polyisocyanurate foam core. This rigid core is firmly bonded between premium-quality protective steel skins. This precise combination ensures a long lifespan under extreme temperature differentials.
Key advantages of our high-efficiency insulated panels include:
Ultra-low thermal conductivity: Delivers maximum energy savings by drastically reducing heat leakage.
Advanced lock-profiling design: Ensures absolute tightness against moisture and air infiltration through continuous joint configurations.
Engineered system synergy: Seamlessly matches our turnkey cold room doors, evaporators, and condensing units. We proudly utilize industry-leading brands like Bitzer, Fusheng, and Heron.

To meet specific project requirements, our panel selection is categorized by application. This allows engineers to choose the optimal design for thermal barrier performance and structural load requirements. Selecting the right variant ensures maximum structural life and thermodynamic efficiency.
Specially designed for freezing chambers, chillers, and distribution centers. They feature tongue-and-groove joints with optional integrated cam-locks for rapid assembly. This design ensures continuous thermal insulation and eliminates thermal leaks at intersections.
Ideal for external warehouse walls and internal industrial partitions. These units offer exceptional mechanical strength and wind load resistance. They also provide aesthetic steel cladding options to suit modern architectural layouts.
Engineered with deep corrugations for high structural load-bearing capacity. These roof systems provide robust weather protection against heavy rain, snow, and solar radiation. They easily maintain core stability over years of exposure.
Designed with perfectly flush joints and corrosion-resistant steel claddings. They are ideal for pharmaceutical, electronic, and hygienic food processing environments. These surfaces fully support frequent sanitation and strict particle control.
We provide precise technical metrics to help engineers and contractors select materials. Our specifications fully comply with strict international standards. Furthermore, our quality assurance processes guarantee reliable performance under heavy operational loads.
Our proprietary core formulations achieve an industry-leading thermal conductivity rating. We maintain a precise core density of 40±2 kg/m³ for optimal thermal-to-weight performance. This delivers unparalleled insulation without adding unnecessary weight to your structural frame.
Our sandwich panels meet international fire classification standards. They consistently achieve Class B1 or B2 fire-retardant performance. Under flame exposure, the core forms a carbonized protective layer. This significantly slows flame spread and reduces smoke. Furthermore, our panels possess a compressive strength exceeding 150 kPa for exceptional structural integrity.
Unlike standard building-material brokers, Shanghai Heleng operates as a complete systems integrator. We manufacture our advanced insulation systems in-house. We then combine them with comprehensive engineering services to support your entire build.
Produced at our intelligent manufacturing hub in Shanghai, our products undergo rigorous quality control. From chemical formulation to precise automated cutting, we monitor every step. This ensures every unit meets exact dimensional tolerances.
As an affiliate of the Luohe Tian Shun Cold Chain Group, we leverage massive industrial resource support. We proudly act as your one-stop project partner. Our team integrates high-efficiency panels with custom cold room doors and premium refrigeration units featuring Bitzer, Fusheng, or Heron compressors.
Matching panel thickness and steel cladding types to operational temperatures is essential for optimal results. Selecting the correct material specifications protects your stored inventory. It also dramatically extends the lifespan of your cold room facility.
| Panel Thickness (mm) | Recommended Temp Range (°C) | Primary Application Types | Recommended Cladding Materials |
|---|---|---|---|
| 50 mm - 75 mm | +5°C to +15°C | Processing rooms, cleanrooms, comfort cooling chambers | PPGI, PVDF (for high humidity) |
| 100 mm - 120 mm | -5°C to +5°C | Medium-temperature chillers, vegetable/fruit storage | PPGI, SUS304 Stainless Steel (food-grade) |
| 150 mm | -18°C to -25°C | Low-temperature freezers, frozen food storage | SUS304 Stainless Steel, PPGI |
| 200 mm | -30°C to -45°C | Blast freezers, extreme low-temp cold rooms | SUS304 Stainless Steel, Heavy-Duty PPGI |
Choosing the right cladding is critical when specifying your materials. Food-grade SUS304 stainless steel is ideal for hygienic processing environments. High-durability PVDF coatings provide essential protection for coastal or chemically active sites. For standard industrial applications, pre-painted galvanized steel (PPGI) provides an outstanding, cost-effective barrier.
Whether you are planning a logistics center or a hygienic food facility, Shanghai Heleng is the premier PIR Panels manufacturer you can rely on. Please contact our technical team today to discuss your project requirements, request detailed thermal specifications, or receive a competitive quotation.
PIR (polyisocyanurate) panels offer significantly higher thermal resistance and superior fire retardancy compared to PUR (polyurethane) panels. Our PIR products carbonize under direct flame exposure rather than melting, acting as a highly effective fire barrier.
We manufacture highly customizable panels in standard thicknesses ranging from 50mm to 200mm. This wide range allows us to cater to precise temperature controls, from high-hygiene clean rooms to extreme blast freezers.
Yes, we serve as a comprehensive one-stop cold storage project partner. Our team supplies the insulated panels, complete structural frames, specialized doors, and advanced refrigeration systems equipped with Bitzer, Fusheng, or Heron compressors.
Absolutely. We supply various cladding options tailored to your facility. Choices include food-grade SUS304 stainless steel, PVDF-coated steel for corrosive coastal areas, and standard high-durability polyester-coated galvanized steel.
