Constructed with an R-8 insulation rating, this 14-inch diameter duct ships in a 25-foot length and features a silver outer jacket. It is used to connect air handling equipment to diffusers, registers, and grilles in supply-air applications. HVAC installers and sheet metal contractors work with this product during new construction and retrofit projects where flexible duct runs are required to navigate framing, joists, and tight plenum spaces.\u003c\/p\u003e\u003cp\u003eThis flexible duct is suited for supply-air runs in forced-air heating and cooling systems. The 14-inch diameter accommodates high-volume trunk-to-branch connections in larger residential systems and light commercial applications. The R-8 insulation value meets or exceeds energy code requirements in many jurisdictions, making it appropriate for unconditioned attic, crawlspace, and mechanical room installations where thermal loss is a primary concern.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eR-8 insulation rating reduces thermal loss in unconditioned spaces\u003c\/li\u003e\n\u003cli\u003e14-inch inner diameter supports high-volume airflow distribution\u003c\/li\u003e\n\u003cli\u003e25-foot length per bag allows for longer uninterrupted duct runs\u003c\/li\u003e\n\u003cli\u003eSilver outer jacket provides a durable, reflective vapor barrier\u003c\/li\u003e\n\u003cli\u003eFlexible construction allows routing around structural obstructions\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and new-installation flexible duct for residential and light commercial forced-air HVAC supply systems requiring a 14-inch diameter insulated duct with R-8 insulation.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician or qualified sheet metal contractor in accordance with SMACNA flexible duct installation standards and local mechanical codes. Power down the air handling unit and confirm the system is de-energized before connecting or disconnecting duct sections. Avoid sharp bends, kinks, or compression of the duct core, as these conditions significantly increase static pressure and reduce airflow. Secure all connections with approved duct straps and UL-listed mastic or metal-backed tape.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInner Diameter\u003c\/strong\u003e: 14 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 25 feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsulation R-Value\u003c\/strong\u003e: R-8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Jacket\u003c\/strong\u003e: Silver\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: THERMAFLEX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 56314000002\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"THERMAFLEX","offers":[{"title":"Default Title","offer_id":51268899406130,"sku":"056314000002","price":154.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308909509.png?v=1780709107","url":"https:\/\/voomisupply.com\/products\/thermaflex-56314000002-insulated-flex-duct-14in-x-25ft-r-8","provider":"Voomi Supply","version":"1.0","type":"link"}
