What are Duct Socks?
Duct socks, air socks, and fabric air ducts are all names for the same technology: a textile-based air dispersion system that distributes conditioned air evenly and draft-free as an alternative to rigid metal ductwork. The terms are interchangeable – “fabric air ducts” is the technically accurate, manufacturer-neutral name, while “duct socks” and “air socks” are the informal terms widely used across the HVAC industry.
Duct socks consist of four components:
Why Duct Socks have so many names?
The variety of names comes from regional habit rather than any difference in the product. Common terms include:
- Duct socks – common informal name in North America
- Air socks – widely used casual term for the same system
- Fabric air ducts / fabric ducting – the technically accurate term
- Textile ducts – common in Europe and technical specifications

Where can duct socks be used?
Duct socks are a versatile air distribution solution, ideal for a wide range of commercial and industrial HVAC applications. Whether you’re designing a system for a large warehouse, a food processing plant, or a sports and entertainment venue, duct socks provide uniform airflow, energy efficiency, and enhanced comfort. Their lightweight design and customizable airflow models make them especially effective in high-ceiling spaces where traditional metal ductwork struggles to deliver even air distribution.
In public facilities like schools, indoor swimming pools, or grow rooms, duct socks outperform conventional air ducts by maintaining consistent temperatures, eliminating drafts, and providing better indoor air quality. Available in antimicrobial, antistatic, and flame-retardant materials, duct socks meet the challenging safety and hygiene requirements of sensitive environments. From simple overhead duct systems in retail stores to complex industrial air duct systems in manufacturing plants, duct socks offer a clean, efficient, and adaptable alternative to traditional industrial ductwork.
