Air Duct
Air Duct & Flexible Connection Fabric (Silicone Coated)
Silicone coated fiberglass fabric for fan flexible connections, non-metallic expansion joints and fire soft joints. Double-side coating for air-tightness; SO₂ media requires alternative coating.

Air Duct & Flexible Connection Fabric
Flexible connections in air ducts, fans and non-metallic expansion joints (compensators) demand a fabric that keeps flexing while staying gas-tight. VETEX supplies silicone coated fiberglass fabric engineered for these joints: double-side silicone coating on 660–1000 g/m² fiberglass base for air-tightness, in widths up to 2000 mm and custom colors.
Choose by Application
Fan Flexible Connections
Soft-finish silicone coated fabric absorbs vibration and misalignment between fan and duct.
Non-Metallic Expansion Joints (Compensators)
For compensators, we recommend heavier base fabric with double-side coating; tell us the media temperature and movement range and we size the ply.
Fire Soft Joints
Fire-rated soft joints between duct sections use the same silicone coated family; specify your fire test standard.
Important Media Note
Silicone rubber must not be used for pipeline compensators carrying flue gas or steam containing SO₂ — for these media we propose an alternative coating system.
Before Quotation, Please Confirm
Confirming these ten points with us speeds up an accurate quotation and avoids later specification disputes:
1. Application (where and how the fabric will be used)
2. Base fabric (e.g. E-glass style 3732 at 430 g/m², or style 3788 at 1650 g/m²)
3. Finished weight (g/m², coating included)
4. Thickness (mm)
5. Coating type (silicone / PU / acrylic / vermiculite)
6. Single-sided or double-sided coating
7. Width (1000 / 1200 / 1500 / 1800 / 2000 mm, or custom)
8. Roll length
9. Color
10. Required standard or test report (e.g. EN 1869, UL 94)
