In the era of climate urgency and carbon neutrality goals, the demand for advanced building envelopes has shifted from mere structural integrity to high-efficiency thermal resilience. Polyisocyanurate (PIR) sandwich panels represent the pinnacle of this evolution. Unlike traditional insulation materials, PIR offers a superior weight-to-performance ratio, making it the preferred choice for modern logistics hubs, pharmaceutical storage, and eco-conscious industrial architecture.
As global supply chains become more complex, the "Cold Chain" requires more than just cooling—it requires an airtight, thermally stable environment that minimizes energy leakage. Our CE-certified PIR panels are engineered to meet these rigorous global standards, ensuring that factories and exporters can maintain product integrity while slashing operational costs.
Our PIR cores achieve a thermal conductivity as low as 0.020 W/m·K, significantly outperforming Mineral Wool and EPS, allowing for thinner walls with better insulation.
CE Certification ensures our panels meet EN 13501-1 fire classification standards. PIR panels provide excellent charring properties, preventing the spread of flames in industrial settings.
High compressive strength makes our sandwich panels suitable for large-span roofing and high-bay cold storage warehouses, capable of withstanding extreme environmental loads.

Our business in refrigeration fields started in 1996, with more than 20 years experience in refrigeration industry, we are confident in our professionality. And our factory is specializing in refrigeration manufacturing and technology.
Ensuring Local Standards through International Excellence
Our PIR sandwich panels are rigorously tested to meet European Economic Area (EEA) safety, health, and environmental protection requirements, facilitating seamless export to EU markets.
From initial design to final installation, we provide localized engineering consultation. Whether you are in Southeast Asia, Europe, or the Americas, our solutions are tailored to local building codes.
With 4 standardized workshops and advanced automatic production lines, we offer OEM services that cater to specific thickness, core density, and surface material requirements.
Providing Precision Temperature Control Across Industries
Large-scale facilities for frozen food storage, utilizing our 200mm PIR panels to maintain temperatures as low as -35°C with minimal energy cost.
Sanitary-grade surface coatings (SS304 or Food-grade PE) combined with PIR cores create the ideal environment for pharmaceutical and biotech labs.
Fast-installation cam-lock PIR panels for distribution centers, allowing for rapid expansion of the cold chain network in urban areas.
We are integrating AI tools to simulate thermal bridge effects in complex cold storage geometries, helping clients optimize panel thickness for maximum ROI.
Research into bio-based polyols to further reduce the carbon footprint of our PIR cores without compromising fire resistance or insulation values.
Development of sandwich panels with integrated temperature and humidity sensors for real-time monitoring of building envelope health.
PIR (Polyisocyanurate) is an evolution of PUR (Polyurethane). It offers significantly better fire resistance and lower thermal conductivity, making it the safer and more efficient choice for industrial applications.
CE Certification ensures the product meets EU safety standards. For exporters and builders, it is a mark of quality and legal compliance, ensuring the panels are safe for use in human-occupied structures.
When properly installed, our PIR panels have a service life exceeding 25-30 years. They are resistant to moisture, mold, and most industrial chemicals.
Yes. We don't just sell panels; we provide design, equipment (condensers, evaporators), doors, and installation guidance for a complete refrigeration system.
