Fabric air duct price list helps buyers estimate the cost to supply and install textile ductwork in commercial or industrial spaces. Typical total prices range from $4-$15 per linear foot for basic systems up to $40-$120 per linear foot for insulated, fire-rated, or custom-profile installations depending on length, diameter, and finish.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Basic Uninsulated Duct (per linear ft) | $4 | $8 | $15 | Assumptions: 8″-18″ diameter, standard polyester fabric, Midwest labor. |
| Insulated or Perforated Duct (per linear ft) | $10 | $22 | $40 | Assumptions: added insulation, perforations for diffusion. |
| Fire-Rated / Class A Fabric (per linear ft) | $25 | $55 | $120 | Assumptions: NFPA/UL ratings, treated materials, larger diameters. |
| Small Project Install (50-200 ft, total) | $300 | $1,100 | $4,000 | Assumptions: bench-top HVAC, simple supports, no complex fittings. |
| Large Project Install (1,000+ ft, total) | $4,000 | $11,000 | $60,000 | Assumptions: industrial plant, custom sections, insulated runs. |
What Buyers Usually Pay For Fabric Air Duct Systems
Most buyers pay by linear foot for fabric air ducts, with an installed price that bundles materials and labor. Typical small-to-medium commercial runs cost $4-$15 per linear ft for uninsulated, $10-$40 per linear ft for insulated or perforated, and $25-$120 per linear ft for fire-rated or specialty fabrics.
Average installed price for a standard office system is about $8-$22 per linear foot including mounts and basic diffusers.
Assumptions: 18″ nominal diameter, 50-500 linear ft runs, 1-2 installers, normal ceiling access.
Breakdown of Costs: Materials, Labor, Equipment, Delivery, Overhead
| Materials | Labor | Equipment | Delivery/Disposal | Overhead |
|---|---|---|---|---|
| $2-$40 per lf (fabric, seams, connectors) | $75-$125 per hour or $2-$12 per lf installed | $100-$600 per day (lifts, scaffolding) | $50-$500 per job (freight, crating) | 10%-25% of job |
Materials and labor typically account for 70%-85% of the installed price; equipment rental and delivery create the rest.
How Diameter, Length, and Fabric Grade Change the Final Quote
Diameter affects material usage nonlinearly: 6-12″ small ducts cost near the low end, 18-36″ common sizes push to average, and 42″+ custom diameters drive high prices. Length amplifies setup overhead on short jobs and reduces per-foot price on long runs.
Expect price step-ups at these thresholds: under 50 lf (higher per-foot), 50-500 lf (standard pricing), over 1,000 lf (volume discounts of 10%-30%).
Fabric grade and treatments alter costs: basic polyester vs. antimicrobial/UV-treated vs. Class A fire-rated fabrics can multiply material price by 1×, 1.5–2×, and 3–6× respectively.
Site Conditions and Mounting Details That Drive Price Changes
Tight access, high ceilings, long vertical drops, or complex fittings increase labor hours and equipment needs. For example, installations above 20 ft often require lifts or scaffolding, adding $200-$1,200 per day to the job.
Locking in easier access and consolidated runs can reduce labor 15%-40% compared with phased, hard-to-reach installs.
Other cost multipliers: multiple bends and transitions (+$5-$30 per fitting), insulated transitions (+$8-$25 per lf), and custom color/printing (+$3-$12 per lf).
Practical Ways To Reduce the Fabric Air Duct Price
Buyers can lower cost by choosing standard diameters and lengths, selecting uninsulated or perforated standard polyester when code allows, and scheduling installation during off-peak season. Prefabricated straight runs cost less than many site-fabricated transitions.
Comparing 3-5 local quotes, bundling multiple buildings, and supplying simple, accurate drawings typically trims final quotes 10%-25%.
Prep work such as clearing ceiling space and pre-installing support anchors also reduces contractor hours and markups.
Regional Price Differences and Typical U.S. Market Deltas
Prices vary by region: Coastal metros and high-wage states are 10%-30% above national average; Midwest and rural areas are often 5%-20% below average. Material freight can add $0.50-$3 per lf for distant shipments.
Budget planners should apply a regional multiplier: Midwest ×0.9, South ×0.95–1.0, Northeast/West Coast ×1.1–1.3.
Three Real-World Quote Examples With Specs and Totals
| Project | Specs | Labor Hours | Price |
|---|---|---|---|
| Small Retail HVAC | 120 lf, 12″ dia, uninsulated, ceiling mounts | 12 hours | $480-$1,200 |
| Office Floor | 420 lf, 18″ dia, perforated, basic supports | 40 hours | $3,360-$9,240 |
| Industrial Plant | 1,200 lf, 36″ dia, insulated + Class B fire | 160 hours | $24,000-$72,000 |
These examples show how size, fabric type, and labor scale alter totals dramatically.
