Constructed with a poly outer jacket and formaldehyde-free fiberglass insulation, it provides effective thermal performance in supply and return air applications. The duct ships in a 25-foot length, making it suitable for branch runs from a plenum or trunk line to individual supply registers. Licensed HVAC technicians and sheet metal installers are the primary installers of this product. The black poly jacket includes UV inhibitors, which extends service life in attic and crawlspace environments where incidental light exposure may occur.\u003c\/p\u003e\n\u003cp\u003eThis flex duct is used in forced-air heating and cooling systems where a flexible connection is needed between rigid ductwork and supply outlets. Common install locations include attic spaces, crawlspaces, and dropped-ceiling plenum areas. The R-6 insulation value meets or exceeds energy code minimums required in most climate zones for supply duct runs located outside conditioned space. It is appropriate for both new construction and retrofit duct replacement work in residential and small commercial settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eR-6 insulation value meets common energy code minimums for unconditioned space installations\u003c\/li\u003e\n  \u003cli\u003eFormaldehyde-free fiberglass insulation core for improved indoor air quality compliance\u003c\/li\u003e\n  \u003cli\u003eUV-inhibited poly outer jacket resists degradation in attic and crawlspace environments\u003c\/li\u003e\n  \u003cli\u003e12-inch diameter suits medium-to-large branch duct runs and trunk-to-register connections\u003c\/li\u003e\n  \u003cli\u003e25-foot length per bag reduces splice points on longer runs\u003c\/li\u003e\n  \u003cli\u003eBlack color-coded packaging and bar-coded product labels support jobsite inventory control\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and new-construction flexible duct for residential and light commercial forced-air HVAC distribution systems requiring a 12-inch diameter, R-6 insulated flexible duct.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eFlexible duct installation should be performed by a licensed HVAC technician in accordance with ACCA Manual D and applicable local mechanical codes. Power down and lock out the air handling unit before making duct connections. Avoid sharp bends, compression, or sagging, as these conditions significantly increase static pressure and reduce system airflow; support intervals and minimum bend radii should follow SMACNA flexible duct installation guidelines. Seal all connections at collars and fittings with UL 181B-listed mastic or approved metal-backed tape before insulating the joint.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 25 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eR-Value\u003c\/strong\u003e: R-6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsulated\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eJacket Material\u003c\/strong\u003e: Poly\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eJacket Color\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUV Inhibited\u003c\/strong\u003e: Yes\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: QUIETFLEX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1260\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"QUIETFLEX","offers":[{"title":"Default Title","offer_id":51138314797362,"sku":"1260","price":104.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305533241.png?v=1778253184","url":"https:\/\/voomisupply.com\/products\/quietflex-1260-flexible-air-duct-r-6-12-in-x-25-ft","provider":"Voomi Supply","version":"1.0","type":"link"}
