High-Performance PU / PIR Panel Chemistry & Core Thermal Dynamics

Understanding the core mechanics of thermal resistance is crucial for architectural design. Polyurethane (PU/PUR) and Polyisocyanurate (PIR) core technologies present the pinnacle of structural thermal insulation solutions.

PU vs PIR Core Insulation Materials

While both systems use high-density polyurethane chemicals, they perform differently under extreme temperatures and fire conditions:

  • Polyurethane (PU/PUR): Polyurethane is optimized for general sub-zero cold room environments. It offers an exceptionally low thermal conductivity factor (λ ≈ 0.022 W/m·K) and creates an excellent seal when bonded with micro-ribbed steel plates.
  • Polyisocyanurate (PIR): Formulated with a higher isocyanate ratio, PIR creates highly cross-linked chemical rings. This molecular structure gives PIR panels Class B1 fire performance (EN 13501-1 standards), making them ideal for high-risk industrial facilities.

Thermal Performance & Structural Configurations

Panel Thickness Recommended Temperature Range U-Value (W/m²·K) R-Value (m²·K/W)
50 mm +5°C to +15°C (Processing Area) 0.44 2.27
75 mm 0°C to +5°C (Chilled Food) 0.30 3.33
100 mm -18°C to -25°C (Frozen Storage) 0.22 4.55
150 mm -25°C to -35°C (Blast Freezing) 0.15 6.67
200 mm -35°C to -50°C (Ultra-Cold Medical) 0.11 9.09
Why Source from Shaanxi, China?

The Strategic Advantages of Our Manufacturing Complex

China has become the global hub for manufacturing cold storage solutions. Our Shaanxi facility leverages this ecosystem to deliver high-quality, cost-effective products that meet international standards.

1. Continuous Automated Lamination Lines

Our facility runs double-belt, continuous automated production systems. This technology ensures uniform density (40-42 kg/m³), flat steel sheets, and excellent adhesion without core voids or delamination issues.

2. Vertical Supply Chain Integration

We source raw materials—including specialized steel coatings and chemicals—from local suppliers. This structural proximity enables cost efficiency, fast lead times, and customization options for panel skins and core thickness.

3. Strict Quality Management & Inspections

Our 10-person dedicated QC team monitors raw material chemistry, mechanical properties, and structural joint tolerances (cam-lock profiles). We guarantee alignment, thermal insulation performance, and zero-defect deliveries.

Global Applications

Macro Cold Chain Solutions & Industrial Scenarios

Turnkey Engineering Projects

Our solutions adapt to diverse temperature requirements and building regulations around the world:

  • Agriculture & Food Processing: Cleanroom environments for processing and packaging fruits, vegetables, meat, and dairy products.
  • Pharmaceutical & Cold Chain Logistics: GMP-compliant facilities designed for medical distribution, vaccines, and biologics requiring strict temperature control (+2°C to +8°C and ultra-low freezers).
  • Logistics Distribution Hubs: Large-scale, high-bay cold storage operations using thick, structurally reinforced sandwich panels.

Advanced Panel Joint Technology

A cold room is only as efficient as its seams. Our panels use a dual-joint connection system that minimizes thermal bridging:

  • Cam-Lock Systems: High-strength, zinc-coated eccentric cam locks are cast into the panel edges during production. This mechanism draws adjacent panels tightly together to create a robust, leak-free seal.
  • Tongue-and-Groove Interlock: For larger warehouse configurations, our double tongue-and-groove joint profile uses dry joints with sealant beads. This design prevents thermal leakage and blocks moisture ingress.
Our Manufacturing Strength

Our Professional Factory & Production Capability

With about 180 workers and a 10-person QC team, we maintain high standards of quality and efficiency. Our factory features a 60,000 square meter production site with 4 standardized workshops equipped with advanced production lines and machinery.

Technical FAQ

Frequently Asked Questions About Cold Room PU Panels

What is the standard density of Shaanxi YuanShengHeTong's PU panels, and why does it matter?

Our standard core density is 40–42 kg/m³. This density offers a balanced combination of mechanical strength and low thermal conductivity (R-value). Lower density foam can compromise structural strength and insulation performance, while higher density does not yield significant gains in thermal resistance.

What options are available for the steel skin of the panels?

We offer pre-painted galvanized steel (PPGI), stainless steel (SUS304 or SUS316), and aluminum-zinc alloys. Steel thickness ranges from 0.4 mm to 0.8 mm. For food processing and pharmaceutical applications, we offer food-grade, corrosion-resistant coatings.

How do PIR panels perform in terms of fire resistance compared to PU?

Our PIR core panels meet European Class B-s2, d0 standards (equivalent to Chinese GB8624 Class B1) for fire safety. Under flame exposure, PIR forms a protective carbonaceous char layer that slows flame spread and minimizes smoke emission, whereas standard PU is classified as Class B2.

Can you provide customized dimensions for panels and cold storage doors?

Yes. We design and manufacture sliding, swing, and vertical lift cold room doors, as well as insulated wall and roof panels, to match specific architectural drawings and project layout requirements.
