Flexible Air Duct
Highly efficient, thermally insulated flexible duct for use in low and medium pressure heating and cooling systems. Acoustically rated, self-extinguishing CPE core easily expands over fittings. Core is permanently bonded to a coated spring steel wire helix that supports an ample blanket of fiberglass insulation over a fiberglass scrim and a tough polyethylene vapor barrier. Smooth liner, insulation, and tough vapor barrier provide even airflow and a double air seal.
Features:
- Acoustically rated, self-extinguishing CPE core
- Easily expands over fittings

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.
