Measuring 12 inches in diameter and 5 feet in length, it features an R-8.0 formaldehyde-free insulation core wrapped in a metalized polyester jacket. The coreless design allows technicians to slide the sleeve over existing ductwork or flexible duct sections to add insulation value where needed. It is installed by licensed HVAC contractors during new construction, renovation, or duct system upgrades where insulated transitions or duct wrap solutions are required.\u003c\/p\u003e\u003cp\u003eThis sleeve is suited for HVAC venting installations where thermal efficiency and condensation control are critical. The 12-inch diameter accommodates larger trunk runs or main supply and return duct sections. The 5-foot length provides a manageable section for field cutting and fitting. The formaldehyde-free insulation meets current indoor air quality standards and is appropriate for occupied residential and commercial spaces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eR-8.0 insulation value for effective thermal performance in HVAC duct systems\u003c\/li\u003e\n\u003cli\u003e12-inch diameter fits larger supply and return duct runs\u003c\/li\u003e\n\u003cli\u003e5-foot length allows field trimming to suit specific installation dimensions\u003c\/li\u003e\n\u003cli\u003eMetalized polyester jacket provides vapor barrier protection and durability\u003c\/li\u003e\n\u003cli\u003eCoreless construction slides over existing duct sections for straightforward retrofits\u003c\/li\u003e\n\u003cli\u003eFormaldehyde-free insulation suitable for occupied residential and commercial spaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style insulated sleeve for 12-inch round flexible or rigid duct in HVAC venting applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by licensed HVAC technicians. Power down the air handling system and verify the duct system is depressurized before beginning work. The sleeve should be secured at both ends with approved duct tape or metal-band fasteners per local mechanical code requirements. Avoid compressing the insulation during installation, as compression reduces the effective R-value.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 5 feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsulation R-Value\u003c\/strong\u003e: R-8.0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eJacket Material\u003c\/strong\u003e: Metalized Polyester\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCore Material\u003c\/strong\u003e: Polyethylene\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCore Type\u003c\/strong\u003e: No Core\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: HVAC Venting\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage\u003c\/strong\u003e: Boxed\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HART COOLEY\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 11000812\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HART \u0026 COOLEY","offers":[{"title":"Default Title","offer_id":51672308973874,"sku":"11000812","price":58.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f27a6fb5bd5c0e8d9f71edc157d81b4d.jpg?v=1787965841","url":"https:\/\/voomisupply.com\/products\/hart-cooley-11000812-flex-duct-sleeve-12in-x-5ft-r-8-0","provider":"Voomi Supply","version":"1.0","type":"link"}
