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 fiberglass 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.
