JOHNS MANVILLE linacoustic rc fiberglass duct liner


Johns Manville Johns Manville Linacoustic RC Fiberglass Duct Liner Johns Manville

Johns Manville Linacoustic® RC duct liner provides superior thermal and acoustical performance and improved handling during fabrication when lining metal ducts. Linacoustic RC’s 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. Manville's unique flame-attenuated technology yields a very controlled fine fiber characteristic that results in a fiberglass core unmatched by Manville's 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.


DESCRIPTION

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.

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 (refer to publication AHS-202).

USES

Linacoustic RC insulation is specifically designed for lining sheet metal ducts in air conditioning, heating and ventilating systems, providing superior acoustical and thermal performance.
