Their permeability and tailored perforations enable controlled airflow patterns that can be designed to match the specific needs of a space, which improves occupant comfort and ventilation efficiency. Additionally, fabric ducts are easier to clean and maintain because many systems can be removed and laundered, addressing health concerns in facilities where air quality is critical. The ability to produce them in a wide range of colors, shapes, and diameters also makes them highly adaptable to aesthetic and functional requirements in both commercial and industrial projects. Fabric ducts are increasingly preferred in modern construction projects due to their sustainability, as they often use recyclable or reusable materials and reduce the need for energy-intensive metal fabrication. Furthermore, in retrofitting projects, fabric ducts provide an economical and practical solution for upgrading HVAC systems without major structural modifications. The improved airflow management, reduced installation complexity, maintenance advantages, and adaptability to modern design and sustainability trends has driven the rapid adoption of fabric ducts globally, positioning them as the fastest-growing material type in the air duct market.

Rectangular ducts are the fastest-growing shape segment in the global air duct market because they maximize space utilization, are easier to integrate into modern building designs, and allow efficient airflow management.

Rectangular air ducts are widely preferred in commercial, residential, and industrial projects because their shape allows them to fit neatly into ceilings, walls, and narrow service spaces without requiring excessive vertical or horizontal room. Unlike round ducts, rectangular ducts can be customized to match the exact dimensions of a space, which makes them ideal for high-density urban construction where every inch of space matters. Their geometric shape allows for the integration of complex HVAC systems, including multiple supply and return branches, while maintaining consistent airflow and minimizing turbulence. Rectangular ducts also facilitate easier connection to diffusers, grilles, and other ventilation equipment, simplifying installation and reducing labor time compared to round or oval ducts. They can be fabricated from a wide range of materials, including steel, aluminum, and fiberglass, providing durability and flexibility in meeting different environmental and building code requirements. Additionally, rectangular ducts are better suited for large-scale commercial or industrial spaces because they can handle higher volumes of air with less pressure loss, which improves energy efficiency and overall HVAC performance.
