Owens Corning QuietR® Rotary Duct Liner is a flexible fiberglass blanket designed for installation inside sheet metal ductwork. It provides exceptional thermal and acoustical control by absorbing equipment noise and minimizing heat transfer through duct walls.The liner features a durable, black-coated airstream surface that resists damage during installation and is treated to inhibit microbial growth. This design ensures long-lasting performance and helps maintain indoor air quality in commercial and residential HVAC systems.
Acoustic Control: Reduces system noise by absorbing fan and air turbulence sounds, achieving a Noise Reduction Coefficient (NRC) of 0.75.Thermal Performance: Provides an R-4.2 insulation value to minimize heat loss or gain through duct walls, improving system efficiency.Durable Airstream Surface: Features a strong, black mat facing treated with an EPA-registered biocide to resist potential microbial growth.High-Velocity Rated: Designed to withstand air velocities up to 6,000 fpm, ensuring liner integrity in demanding applications.Fire Safety: Meets stringent fire safety standards with a surface burning characteristic rating of 25 for flame spread and 50 for smoke developed.Certified for Indoor Air Quality: GREENGUARD Gold certified for low chemical emissions, contributing to healthier indoor environments.
