Owens Corning OCR15013512100 Quietr Rotary Duct Liner 1 Inches X 35.5 Inches X 100 Foot Roll R4.2

Product Description

The Owens Corning OCR15013512100 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 by 35.5 inches wide and comes in a 100-foot roll, providing approximately 295.83 square feet of coverage per roll. It carries an R-value of R4.2, which means it delivers solid thermal resistance to help reduce heat gain or heat loss through duct walls. This is important in both heating and cooling applications, where uninsulated ducts can waste significant energy and reduce system efficiency. HVAC installers and sheet metal contractors rely on rotary duct liner to line the interior of rectangular and round ducts during fabrication. The liner is applied before assembly, which helps streamline installation and ensures even coverage across duct surfaces. The OCR15013512100 features a Noise Reduction Coefficient of 0.7, which means it absorbs fan noise, airflow turbulence, and the popping or booming sounds that bare sheet metal ducts can produce during system operation. This makes it a practical choice for occupied buildings where noise control matters, including schools, hospitals, office buildings, and multifamily residential projects. The airstream surface is treated with an EPA registered biocide that resists bacterial and fungal growth, helping protect indoor air quality over the life of the installation. The fiberglass composition is durable and compatible with standard duct liner adhesives and mechanical fasteners. This product ships as a single roll and is manufactured in Mexico. It is subject to California Proposition 65 requirements. HVAC technicians, mechanical contractors, and sheet metal fabricators working on duct insulation, thermal performance upgrades, or noise attenuation projects will find this liner meets common commercial and residential specifications.

• R4.2 thermal resistance reduces heat loss and heat gain through sheet metal duct walls
• Noise Reduction Coefficient of 0.7 absorbs fan noise, turbulence, and duct rumble for quieter system operation
• EPA registered biocide on the airstream surface resists bacterial and fungal growth to support indoor air quality

Product Highlights

The Owens Corning OCR15013512100 QuietR Rotary Duct Liner delivers combined thermal and acoustical performance in a single fiberglass product, making it a reliable choice for HVAC duct insulation and noise control applications in commercial and residential construction.
