Product Features
Johns Manville Linacoustic® RC duct liner provides superior thermal and acoustical performance and improved handling during fabrication when lining metal ducts. Linacoustic RCs airstream surface is coated with our proprietary Permacote® coating, which provides a durable surface that is resistant to dust and dirt and provides added product protection against microbial growth. Our unique flame-attenuated technology yields a very controlled fine fiber characteristic that results in a fiber glass core unmatched by our competitors. This ensures consistently high performance and easy processing on a wide range of duct fabrication equipment. Building occupants benefit from less unwanted noise and more consistent temperatures for improved comfort.
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 (refer to publication AHS-202)
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 protective agent to protect the coating from potential growth of fungi and bacteria
Linacoustic® RC duct liner meets all requirements for fungi and bacterial resistance
Tests were conducted in accordance with ASTM C1338 and ASTM G21 (fungi testing) and ASTM G22 (bacteria resistance testing)
As with any type of surface, microbial growth may occur in accumulated duct system dirt, given certain conditions, This risk is minimized with proper design, filtration, maintenance and operation of the HVAC system
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
Applications: For lining sheet metal ducts in air conditioning, heating and ventilating systems, providing superior acoustical and thermal performance
