The THERMAFLEX 056318000001 Flex-Vent KM insulated duct is designed for low- to medium-pressure cooling and heating HVAC systems. Suitable for both supply and return sections, it resolves misalignment issues and facilitates system extensions. The unit features a smooth liner, thermal insulation, a tough outer vapor barrier, and a double air seal.
Efficient R-8 insulation prevents heat from entering or escaping your ducts. It meets UL 181 and CUL S110 requirements and NFPA 90A and 90B standards.
