Description

  • The Thermaflex Flex-Vent KM Flexible Insulated Duct is an industrial-grade, commercial-grade equipment component engineered specifically to ensure efficient, quiet thermal airflow delivery across demanding forced-air system environments.
  • Fabricated from a premium laminated polyester inner core and encapsulated corrosion-resistant steel wire helix, this high-performance component handles velocities up to 5000 FPM and 10 inches of water gauge pressure while permanently resisting vapor barrier unravelling, air leakage, and thermal energy transfers.
  • The innovative bi-directional reinforced metallized jacket and fiberglass blanket significantly improve system acoustics to smoothly handle high-volume structural supply runs without causing duct sweating, heat loss, or audible vibration noises.
  • Ideal for licensed HVAC/R technicians, mechanical contractors, and residential building supervisors, this durable flexible duct features a highly compressible composition to rapidly execute clean, direct field installations, maximize overall energy efficiency, and permanently eliminate expensive callback issues.
