Why Ductsox
DuctSox is a leading manufacturer of fabric air dispersion and ductwork systems for commercial and industrial HVAC applications. Based in Peosta, Iowa, DuctSox offers innovative alternatives to traditional metal ductwork, ideal for open ceilings, critical environments, and underfloor air systems. Their fabric ducts are cost-effective, easy to install, environmentally friendly, and reduce on-site material waste.
DuctSox systems are custom-designed for each project, supporting simple or complex layouts with features like elbows, Ts, and transitions. Products are available in diameters from 6 to 80 inches and are assembled using zippered sections. Widely accepted by ASHRAE, UL (U.S. & Canada), and the International Code Council, DuctSox serves diverse sectors including retail, education, laboratories, food processing, and government facilities.
With a strong focus on quality, service, and innovation, DuctSox has expanded its range to include specialized products like LabSox, KitchenSox, UFSox, and SkeleCore—their advanced internal support system.

Why Fabric Ductwork?
Fabric Advantages & Benefits:
DuctSox Fabric Duct and Diffuser Systems have many advantages and benefits, many of which are green and can be helpful in attaining LEED credits.
Simplified Design/Uniform Air Dispersion:
This means less ductwork! Because the entire DuctSox System is a diffuser, air can be supplied to the occupied space in a more efficient pattern. DuctSox Systems can be designed with fittings similar to metal ductwork, including many standard zippered fittings and unlimited customization to match any application requirements.
Cost Savings/Minimal Labor Hours:
The cost of a DuctSox System are comparatively lesser than metal. The cost savings of air porous DuctSox are even more dramatic when compared to insulated/double-walled spiral metal duct or where costs like insulation, grills, diffusers, dampners and false roofing add to the basic cost in a metal ducting system. Fabric Ducts can be installed in a comparatively shorter period of time when compared to metal duct systems.
Lightweight/Easy to Ship:
The weight of a DuctSox System can be significantly less than a comparable metal system. Designing with DuctSox Systems means lighter roof loads, ease of handling and reduced need for power lifting equipment. DuctSox can be packaged and shipped to your location from any of our manufacturing facilities. Smaller and lighter packages reduce transportation costs and damage.
Quiet:
With a properly designed DuctSox System, air is delivered quietly and without the resonating properties found in metal. Additionally, DuctSox fabrics provide noise absorption benefits in the occupied space.
Air Porosity:
Air passing through the fabric eliminates/reduces the risk of condensation and deflect airborne dust from accumulating on DuctSox surfaces.
Hygienic:
Some of our fabrics feature an active antimicrobial agent that inhibits bacteria growth.
Easy to Maintain/Clean:
Cleaning metal ductwork can be difficult and expensive—these costs are often overlooked. A dirty duct (interior) can be a leading contributor to sick building syndrome and human health problems. When it comes time to clean your DuctSox System, it can be easily removed and laundered. The cleaning process can involve either vacuum cleaning and/or hand or machine washing depending on the fabric. DuctSox Systems are designed with zippered sections for ease of handling and are sized to fit into industrial washing machines.
Ease of Use & Forgiving:
Colorful/Personalization:
Our fabrics are available in a variety of standard colors and patterns, including custom colors to match any interior decor. DuctSox can personalize your fabric air dispersion systems to advertise your company or school logos, mascots, inspirational sayings, sponsors or suppliers.
GREEN Advantages:
In addition to having recycled options for some of our fabrics, other Green advantages include:
In open ceiling architecture, traditional metal duct systems discharge air through side-mounted metal diffusers usually spaced 10 to 15 feet apart. The air is directed to specific zones resulting in less efficient mixing of air in the occupied space and often causing drafting and hot or cold spots.
With a DuctSox System, the air is discharged more uniformly along the entire length of the DuctSox system providing consistent and uniform air dispersion in the occupied space. Uniform air dispersion means better air mixing. Higher entrainment ratios result in consistent throw performance for orifices or linear vents.
Fabric Duct vs. Sheet Metal Duct Study
Fabric duct is also 24.5-percent more efficient than conventional sheet metal duct and diffuser systems, according to a recent computational fluid dynamics (CFD) energy study performed by the Iowa State University Mechanical Engineering Dept. in Ames, Iowa. The 10-month-long study, “Thermal Comparison Between Ceiling Diffusers and Fabric Ductwork Diffusers for Green Buildings,” proved fabric diffuser systems heat/cool rooms faster and more uniformly to satisfy temperature set points. This results in reduced mechanical equipment runtime, thus saving energy in the process.
There are three different areas to consider for maintaining your DuctSox Products.
Performance:
DuctSox products have been refined to reduce or eliminate required maintenance. Over years of use, extensive dirt build up will have little, if any, effect on the air dispersion performance of our Premium (Sedona-Xm and TufTex), Commercial (Verona or DuraTex) products.
Aesthetics:
Keeping the exterior of your DuctSox looking clean may be very important to you. If this is the case, your maintenance schedule should be no different than with metal duct. Although, keeping your DuctSox looking clean can be much easier and less expensive than keeping your metal duct clean. There are a few things that may help reduce the exterior dusting of a DuctSox, including selecting a porous fabric or cycling the system once daily. The most common options for cleaning your DuctSox include vacuuming and/or using compressed air, or it can be easily removed and laundered.
Hygienic:
Over its lifetime, the interior of a duct system will collect dust and/or other micro-organisms that have been known to contribute to sick building syndrome. DuctSox has a distinct advantage over metal—you can completely launder your fabric duct system. This allows you to clean both the inside and outside of your HVAC system helping to eliminate the contributors of sick building syndrome.
Overall, the laundry requirements for each space varies based on the quality of the filters in the air handling unit, the amount of dirt entrainment entering the space (on people’s shoes and/or clothing), and other location related issues (e.g. near farmland). Based on our experience, average commercial spaces with relatively high traffic and 50% efficient filters may choose to launder their DuctSox after five to seven years. If your fabric is white, a more frequent schedule may be necessary.
All Fabrics
If the system becomes dirty/soiled during installation, please coordinate a proper cleaning prior to completion.
Exterior surface dirt can, most frequently, be blown off using a combination of a brush and compressed air.
DuctSox Fabric Air Dispersion Products takes great pride in upholding the highest quality standards. Part of those high standards include regulatory compliance testing. Regulatory compliance and codes are generally governed by a regional code body. In some instances, individual cities have a regulatory code body. Product testing is an on going process. Please check back for up-to-date information.
