Owens Corning OCL1501X47.5X100 Quietr Rotary Duct Liner 1 Inches X 47.5 Inches X 100 Foot Roll R4.2 Fiberglass

Product Description

The Owens Corning OCL1501X47.5X100 QuietR Rotary Duct Liner is a fiberglass insulation liner designed for use inside sheet metal ductwork in commercial and residential HVAC systems. This product measures 1 inch thick, 47.5 inches wide, and comes in a 100-foot roll, providing approximately 395.83 square feet of coverage per roll. It carries an R-value of R4.2, making it effective at reducing heat transfer through duct walls and improving the overall thermal efficiency of an air distribution system. HVAC technicians and mechanical contractors rely on duct liners like this one to meet energy codes, control noise, and maintain conditioned air temperatures as air travels from the air handler to the supply registers. The QuietR Rotary Duct Liner is manufactured with a fiberglass composition and treated with an EPA registered biocide that protects the airstream-facing surface from bacterial and fungal growth. This antimicrobial treatment helps maintain indoor air quality over the life of the installation. The liner absorbs fan noise and air turbulence generated by the blower and reduces popping sounds that occur as sheet metal ducts expand and contract with temperature changes. These acoustical benefits are measured by a Noise Reduction Coefficient of 0.7, which reflects strong sound absorption performance in typical ductwork applications. The product ships as a single roll and is well suited for rotary duct liner machines, which score and perforate the liner to allow it to conform to round duct profiles. It is a practical choice for new construction and retrofit duct insulation projects where both thermal performance and sound attenuation are required. Installation crews working on commercial office spaces, hotels, hospitals, and multi-family residential buildings frequently specify this type of liner to meet mechanical and acoustic performance standards.

• R4.2 thermal rating reduces heat loss and heat gain through sheet metal duct walls
• Noise Reduction Coefficient of 0.7 absorbs blower noise, air turbulence, and duct expansion sounds
• EPA registered biocide on the airstream surface resists bacterial and fungal growth

Product Highlights

The Owens Corning OCL1501X47.5X100 QuietR Rotary Duct Liner delivers strong thermal and acoustical performance in a single fiberglass roll, making it a reliable choice for HVAC duct insulation projects that require both energy efficiency and noise control.
