• Complies with NFPA Standards 90A and 90B Corrosion-resistant steel wire helix Fully lined for efficient air delivery The outer vapor barrier is a jacket of fiberglass scrim reinforced metallized film laminate Quality KM installations produce referrals that increase volume and profits Made with Owens Corning® EcoTouch® formaldehyde-free Insulation Made with 99% natural materials and highest recycled content Also, it is the only fiberglass insulation listed in the USDA BioPreferred catalog

Strong polyester film laminated and encapsulating a heavy, corrosion-resistant steel wire helix, forms the inner core and supports a thick blanket of fiberglass insulation. Outer vapor barrier is bi-directional scrim reinforced gray polyester. Designed for low to medium pressure systems. Flex-Vent® KPE is a thermally insulated, fully lined, UL 181 Class 1 flexible air duct designed for low to medium pressure cooling and heating HVAC systems. It can be used in either supply or return sections and provides economical means for handling misalignment between systems components and ducting around obstacles where fabricated and fitted ducts are difficult and costly to use. It is equally suitable for new jobs or retrofit work and is especially useful when making system extensions or for changing conditioned zones, now or in the future. Compliance to NFPA Standards allows you to install lengths longer than the 14 ft limitation applying to connectors. Flex-Vent® KPE is a highly efficient part of the total duct system because the smooth liner, the ample insulation and tough outer vapor barrier provide good airflow, thermal insulation and a double air seal.
