Fabric ducts are air distribution systems made of absorbent fabrics that deliver conditioned air for ventilation, heating, or cooling. Compared to traditional duct systems, fabric ducts offer better acoustical performance, reduce energy consumption, and improve indoor air quality. They are easy to install and customize, making them suitable for commercial, industrial, and institutional settings such as offices, retail spaces, warehouses, gymnasiums, and educational facilities.
