International Market Share Trends of Phenolic, PIR, and Steel Ducts: A Comparative

International Market Share Trends of Phenolic, PIR, and Steel Ducts: A Comparative

 Steel ducts remain the backbone of HVAC systems due to their durability and high-pressure handling capabilities. However, their market share has gradually declined (from ~60% in 2015 to ~45% in 2024) as lightweight alternatives gain ground.  

Regional Variations: Steel retains dominance in heavy industrial sectors (e.g., oil and gas) and regions with low insulation requirements, such as parts of Southeast Asia.  

Innovation: Galvanized and stainless steel variants with anti-corrosion coatings are revitalizing demand in coastal and high-humidity areas.  

4. Drivers of Market Shifts

Regulatory Pressures: Stricter energy codes (e.g., EU’s Energy Performance of Buildings Directive) favor phenolic and PIR ducts.  

Cost Dynamics: Steel ducts face rising material costs, while PIR and phenolic benefit from economies of scale in polymer production.  

Technological Integration: Smart manufacturing, as seen in Midea’s “Global Lighthouse Network” factories, enhances production efficiency for advanced materials.  

5. Future Outlook

By 2030, phenolic and PIR ducts are projected to collectively capture over 50% of the global market, driven by urbanization and net-zero building targets. Steel ducts will remain critical in niche sectors but require innovation to offset environmental criticisms. Emerging markets like India and Brazil present growth opportunities, albeit with challenges in balancing cost and performance.  

Conclusion

The international ductwork market reflects a nuanced interplay of innovation, regulation, and sustainability. While phenolic and PIR ducts lead in energy-efficient applications, steel ducts persist in industrial resilience. Companies like Midea, investing in global supply chains and R&D, exemplify the strategic shifts needed to thrive in this competitive landscape.
