Constructed with a metalized polyester jacket and polyethylene core material, this sleeve delivers R-8.0 insulation performance without the use of formaldehyde in its insulation composition. Measuring 7 inches in diameter and 5 feet in length, it ships pre-cut and ready for field installation. HVAC technicians use this sleeve to insulate and protect flexible duct runs, transition sections, and venting connections where thermal efficiency and vapor barrier performance are required.\u003c\/p\u003e\n\u003cp\u003eThis sleeve is suited for venting and duct insulation work in HVAC systems where a coreless sleeve format is preferred. The 5-foot length accommodates standard duct runs and short transitions. Its metalized polyester outer jacket reflects radiant heat and resists moisture, making it appropriate for attic, crawlspace, and mechanical room installations. The formaldehyde-free insulation composition is consistent with current indoor air quality standards used in residential construction and light commercial work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eR-8.0 insulation value for effective thermal performance in HVAC venting applications\u003c\/li\u003e\n  \u003cli\u003eMetalized polyester jacket provides radiant heat reflection and moisture resistance\u003c\/li\u003e\n  \u003cli\u003eFormaldehyde-free insulation composition supports indoor air quality requirements\u003c\/li\u003e\n  \u003cli\u003eCoreless sleeve design for use over existing duct or as a standalone insulation wrap\u003c\/li\u003e\n  \u003cli\u003eUL Classified construction for use in compliant HVAC installations\u003c\/li\u003e\n  \u003cli\u003ePre-cut 5-foot length reduces field measuring and trimming time\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style flexible duct sleeve for 7-inch diameter HVAC venting and duct insulation applications in residential and light commercial systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed HVAC technicians as part of duct insulation or venting work. Shut down the air handling system and relieve any system pressure before working on connected ductwork. Secure sleeve ends with approved foil tape or mechanical fasteners in accordance with local mechanical codes and manufacturer guidelines. Do not compress the insulation layer during installation, as compression reduces effective R-value.\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: 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\u003eListing\u003c\/strong\u003e: UL Classified\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Type\u003c\/strong\u003e: Boxed\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: HART COOLEY\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 11000807\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HART \u0026 COOLEY","offers":[{"title":"Default Title","offer_id":51671726588210,"sku":"11000807","price":43.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b03a20bb2e33b2f0aeb7150a4488a46e_82808bd6-fc86-4b8e-b4b4-bfdce369d7fe.jpg?v=1787962507","url":"https:\/\/voomisupply.com\/products\/hart-cooley-11000807-flex-duct-sleeve-7in-x-5ft-r-8-0","provider":"Voomi Supply","version":"1.0","type":"link"}
