This roll-format liner provides both thermal insulation and acoustic attenuation within air distribution systems, helping to reduce heat loss and dampen airborne noise generated by fans and airflow. At 1 inch thick and 35.5 inches wide, the 100-foot roll covers substantial duct runs in a single product, minimizing seam count and speeding installation. HVAC sheet metal contractors and mechanical insulation specialists are the primary installers of this material in commercial and residential applications.\u003c\/p\u003e\u003cp\u003eType 150 duct liner is suited for rectangular and flat-oval sheet metal ductwork where internal lining is specified by the mechanical engineer or required to meet project acoustical and thermal performance targets. The 35.5-inch width is sized to fit standard duct liner fabrication workflows, and the roll format is compatible with rotary or pin-back application methods. This product is appropriate for supply and return air duct systems operating within standard HVAC temperature and velocity ranges.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 150 classification for internal duct liner applications in HVAC systems\u003c\/li\u003e\n\u003cli\u003e1 inch thickness provides thermal insulation and noise reduction within duct interiors\u003c\/li\u003e\n\u003cli\u003e35.5 inch width accommodates standard sheet metal duct liner cutting and fitting workflows\u003c\/li\u003e\n\u003cli\u003e100-foot roll length reduces seam count and minimizes material handling on large duct runs\u003c\/li\u003e\n\u003cli\u003eRoll format compatible with rotary application equipment for mechanical insulation crews\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use as an internal liner in HVAC sheet metal duct systems, including rectangular and flat-oval supply and return air ducts.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by licensed sheet metal contractors or qualified mechanical insulation technicians following SMACNA duct liner installation standards and applicable local mechanical codes. Power down the air handling system before cutting or fitting liner inside ductwork. Adhesive and mechanical fasteners such as weld pins or stick clips are typically used to secure duct liner to sheet metal surfaces. Avoid compressing the liner material, as compression reduces both thermal and acoustic performance.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: Rotary Duct Liner\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClassification\u003c\/strong\u003e: Type 150\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 35.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRoll Length\u003c\/strong\u003e: 100 feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: HVAC Sheet Metal Ducts\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: CERTAINTEED\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 716877\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CERTAINTEED","offers":[{"title":"Default Title","offer_id":51346986598706,"sku":"716877","price":415.85,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310554655.jpg?v=1782095639","url":"https:\/\/voomisupply.com\/products\/certainteed-716877-rotary-duct-liner-1x35-5x100-ft-type-150","provider":"Voomi Supply","version":"1.0","type":"link"}
