 
Flexible Air Duct
Non-insulated UL181 Class 1 flexible air duct, extremely strong with heavy fiberglass cloth fabric permanently bonded to a corrosion resistant spring steel wire helix. For all pressure heating and cooling systems. A superior alternative in applications where insulated duct is not required or cannot be used, e.g., clean room applications. Unlike connector-rated products, S-TL is not limited to length of run.
Features:
- Reduced total installation cost
- Long standard lengths help reduce waste
- All components are self-extinguishing

Thermaflex flexible duct has been awarded GREENGUARD Certification by the GREENGUARD Environmental Institute (GEI). To earn certification Thermaflex products went through a series of rigorous emissions test to confirm the level of volatile organic chemicals (VOC) emitted. These tests proved positive in enabling Thermaflex to gain certification by the GREENGUARD Certification Program, the only independent program for low emitting-products.
