What DuctSox Corporation does

DuctSox Corporation, founded in 1980 and headquartered in Dubuque, Iowa, is a manufacturer of custom-engineered fabric air dispersion products used in commercial and industrial HVAC applications. The company designs and produces fabric ductwork, diffusers, retention and suspension systems, and specialty fabrics (including antimicrobial Opti-X, anti-static DataSox, chemical-resistant ChemSox, and food-grade TufTex and DuraTex) that replace traditional metal ductwork with engineered textiles distributing air along the entire duct length through surface porosity, microperforations, or laser-cut orifices. Its patented SkeleCore tensioning platform includes FTS, Pull-Tight, and the newly launched ETS system for ultra-large diameters up to 156 inches, enabling fabric solutions for stadiums, arenas, aircraft hangars, and convention centers.

DuctSox operates as a wholly-owned subsidiary of Rite-Hite Holding Corporation and sells through a global network of manufacturer's representatives covering dozens of countries, supported by inside sales and engineering teams that provide custom design assistance using computational airflow modeling. Named reference customers include Allegiant Stadium, Texas Christian University, Liquid Web, Involta, Kalahari Resort, and Venida Packing Company, spanning athletic facilities, aquatic centers, higher education, data centers, food processing, grow facilities, K-12 schools, laboratory and healthcare, and manufacturing and warehousing. The portfolio is supported by UL 2518, NFPA 90A, ICC IMC, IAPMO UMC, CAN/ULC S102.2, BS 5867, and GB8624-2006 certifications.

Pricing is project-specific and not publicly disclosed, with claimed installed cost savings of 20-80% versus comparable metal ductwork. A separate SimpleSox e-commerce site (simple-sox.com) sells pre-made adjustable fabric ductwork directly to SMB customers with simple open-ceiling applications. Adjacent offerings include ZOO Fans for destratification and JetVent garage ventilation, extending the product line beyond ductwork into broader air movement.
