Product Features
Linacoustic® RC insulation is a flexible duct liner made from strong glass fibers bonded with a thermosetting resin. The airstream surface is protected with JM's exclusive Reinforced Coating system, which combines our state-of-the-art Permacote® acrylic coating with a flexible glass mat reinforcement to provide a smooth airstream surface.
Improves indoor building environment: Linacoustic® RC duct liner improves indoor environmental quality by helping to control both temperature and sound
Resistant to dust and dirt: the tough acrylic polymer permacote coating helps guard against the incursion of dust or dirt into the substrate, minimizing the potential for biological growth
Will not support microbial growth: Permacote coating is formulated with an immobilized, EPA-registered agent to protect the coating from potential growth of fungi and bacteria
Linacoustic® RC duct liner meets all requirements for fungi and bacterial resistance
Cleanability: If HVAC system cleaning is required, the reinforced coating airstream surface may be cleaned with industry-recognized dry methods
Highly resistant to water: the reinforced coating surface provides superior resistance to penetration of incidental water into the fiber glass wool core
Easy to fabricate: Linacoustic® RC duct liner is lightweight and easy to handle
Minimizes pre-installation damage: Linacoustic® RC duct liner's reinforced coating system is highly resistant to damage that can occur during in-shop handling, fabrication, jobsite shipping and installation
Noise reduction coefficient (NRC): 0.85 (R6)
Factory-applied edge coating edge coating is factory applied to the edges of the liner core, ensuring coverage of the leading edges per NAIMA/SMACNA requirements, shop fabrication cuts may be coated with SuperSeal® edge treatment
