Equip your air distribution system with this Thermaflex Flex-Vent KM insulated duct! This flexible unit is designed for use in low- to medium-pressure cooling and heating HVAC systems. It can be used in both supply and return sections, and it allows you to resolve issues with misalignment between system components and with ducts installed around obstacles.

This efficient unit is composed of a smooth liner, thermal insulation, a tough outer vapor barrier, and a double air seal. The inner core is formed of laminated, strong polyester film that encapsulates a heavy, corrosion-resistant steel wire helix. It is fully lined with a thick blanket of EcoTouch formaldehyde-free fiberglass insulation for efficient air delivery. The outer vapor barrier features a jacket of fiberglass scrim reinforced with metallized film laminate, and it will not unravel.

This unit is quick and easy to install, and it is a cost-effective alternative to fabricated and fitted ducts. It is made with natural materials and a high level of recycled content. It boasts an impressive R-8 thermal application value to prevent heat from entering or escaping your ducts, and it has an internal operating temperature range of -20 to 250 degrees Fahrenheit.
