This duct is designed for supply and return air distribution in residential and light commercial forced-air HVAC systems. The R8 insulation rating helps reduce heat loss and heat gain across duct runs, improving system efficiency. The rip-stop foil construction adds durability against punctures and tears during handling and installation. Licensed HVAC technicians typically specify and install this product as part of new construction or retrofit duct system work.\u003c\/p\u003e\n\u003cp\u003eThis flex duct is suited for residential and light commercial applications where insulated flexible duct runs are required between supply plenums, takeoffs, and diffusers or registers. It is appropriate for attic, crawl space, and conditioned-space installations where code-compliant insulated ductwork is required. The 25-foot bag length provides enough run for most branch duct drops and lateral runs without requiring splices.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eR8 insulation rating reduces thermal losses across duct runs\u003c\/li\u003e\n  \u003cli\u003e7-inch diameter fits standard round takeoffs and collars\u003c\/li\u003e\n  \u003cli\u003e25-foot length per bag minimizes splices on longer runs\u003c\/li\u003e\n  \u003cli\u003eRip-stop foil outer jacket resists tears and punctures during installation\u003c\/li\u003e\n  \u003cli\u003eSilver foil finish compatible with standard mastic and foil tape sealing methods\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style flexible duct for residential and light commercial forced-air HVAC systems requiring 7-inch insulated branch duct runs with an R8 insulation value.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eFlexible duct of this type is installed by licensed HVAC technicians in accordance with applicable mechanical codes, including SMACNA guidelines and local jurisdiction requirements. Fully extend the duct before securing to avoid compression, which degrades airflow performance and effective R-value. Secure each end with an approved clamp and seal all connections with listed mastic or foil tape rated for HVAC ductwork. Support the duct at intervals required by the applicable mechanical code to prevent sagging.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 25 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsulation Rating\u003c\/strong\u003e: R8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eJacket Material\u003c\/strong\u003e: Rip-stop foil\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Silver\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCategory\u003c\/strong\u003e: Flex Duct\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 87864000785\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: FLEXDUCT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 85SERIESBAG\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FLEXDUCT","offers":[{"title":"Default Title","offer_id":51306364469554,"sku":"85SERIESBAG","price":114.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309549119.jpg?v=1781290583","url":"https:\/\/voomisupply.com\/products\/flexduct-85seriesbag-flex-air-duct-7-in-25-ft-r8-silver","provider":"Voomi Supply","version":"1.0","type":"link"}
