The outer jacket is constructed from a tri-directional fiberglass scrim reinforced, metallized polyester for durability and vapor resistance. The inner core is air-tight, maintaining system efficiency across the full run length. This product carries UL 181, Class 1 Air Duct certification, meeting the code requirements most jurisdictions mandate for flexible duct installations. It is typically installed by licensed HVAC technicians during new construction or system retrofit work.\u003c\/p\u003e\n\u003cp\u003eThis flexible duct is suited for supply and return air distribution in forced-air HVAC systems where flexible connections or branch runs are required. The R8 insulation value makes it appropriate for unconditioned spaces such as attics and crawlspaces where higher thermal performance is needed to limit heat gain or loss. The 10-inch diameter accommodates higher-volume branch or trunk runs typical in larger residential or light commercial applications. Compatible system configurations include those requiring UL 181, Class 1 rated flexible air duct per local mechanical codes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eUL 181, Class 1 Air Duct certified for code-compliant installations\u003c\/li\u003e\n  \u003cli\u003eR8 insulation rating for use in unconditioned attic, crawlspace, and plenum environments\u003c\/li\u003e\n  \u003cli\u003eTri-directional fiberglass scrim reinforced metallized polyester outer jacket\u003c\/li\u003e\n  \u003cli\u003eAir-tight inner core rated for low-to-medium operating pressures\u003c\/li\u003e\n  \u003cli\u003e10-inch diameter x 25-foot length for larger branch and trunk run applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a UL 181, Class 1 compliant flexible air duct for use in low-to-medium pressure forced-air HVAC distribution systems requiring R8 insulated flexible duct in 10-inch diameter configurations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician in accordance with local mechanical codes and SMACNA flexible duct installation guidelines. Power down the air handling system and verify the system is de-energized before connecting or sealing duct sections. Secure all connections with approved drawbands and UL 181B-listed mastic or tape as required by the applicable mechanical code. Avoid sharp bends or excessive compression of the duct, as both conditions reduce airflow and effective insulation performance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 10 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: R8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCertification\u003c\/strong\u003e: UL 181, Class 1 Air Duct\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Jacket Material\u003c\/strong\u003e: Tri-directional fiberglass scrim reinforced metallized polyester\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperating Pressure\u003c\/strong\u003e: Low-to-medium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 29 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 15 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 15 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 20.52 pounds\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: ATCO RUBBER PRODUCTS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: FD-10X25-R8FB\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ATCO RUBBER PRODUCTS","offers":[{"title":"Default Title","offer_id":51267843457330,"sku":"FD-10X25-R8FB","price":121.1,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308913451.webp?v=1780691956","url":"https:\/\/voomisupply.com\/products\/atco-rubber-products-fd-10x25-r8fb-flex-duct-10in-x-25ft-r8","provider":"Voomi Supply","version":"1.0","type":"link"}
