What matters most when selecting fabric duct materials?
For ventilation fabric ducts and flame-retardant fabric air distribution systems, performance comes down to five critical factors: tensile strength, processability, flexibility, flame retardancy, and airtightness. These directly impact system durability, safety, and overall effectiveness.
Flame-retardant fabric ductwork has become a preferred choice for modern fire-resistant ventilation systems. Woven from specialized fibers, this flexible air distribution solution—often called fabric duct or air sock—delivers uniform airflow, excellent anti-condensation properties, lightweight construction, strong water resistance, and faster installation compared to traditional metal ducts.
Suntex has invested significantly in developing flame-retardant fiber fabrics with specialized coatings. Select product lines achieve fire safety ratings of GB8624-2016 Class A2 and EN13501-1 Class A2, while also offering anti-condensation performance, abrasion resistance, and water repellency. Available in a wide range of colors—including gray, white, red, yellow, green, and black—these systems combine safety with visual flexibility.
Common material options include silicone-coated fabrics and PU-coated fiberglass fabrics, each suited to different application requirements.
When specifying fabric air distribution systems, prioritizing these performance indicators ensures both safety and long-term operational reliability.
