The Permacote is an antimicrobial agent used in the RC as well as their lower tier Liner, the PM.
Linacoustic RC (Reinforced Coating) is a flexible glass duct liner, manufactured using resilient glass fibers bonded with a thermosetting resin. The smooth airstream surface is protected with a durable glass-mat facing that is coated with an EPA-registered antimicrobial agent, Permacote. This improves moisture resistance and helps protect the product against damage from mold or fungi growth. The edges of Linacoustic RC are also coated with Permacote.
Advantages of Permacote Acrylic Coating
- Improved 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 coating, Permacote, helps guard against the incursion of dust or dirt into the substrate, minimizing the potential for biological growth.
- Will Not Support Microbial Growth. Permacote is formulated with an immobilized, EPA-registered antimicrobial agent in order to, to protect the coating from damage caused by potential fungi or bacterial growth.
- Highly Resistant to Water. Linacoustic RC’s reinforced surface-coating provides superior resistance to incidental water penetration into the fiber glass wool core.
- Cleanability. If HVAC system cleaning is required, the airstream surface may be cleaned with industryrecognized dry methods. See the North American Insulation Manufacturers Association (NAIMA) “Cleaning Fibrous Glass Insulated Air Duct Systems.” (NAIMA)
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).
This helps contractors more productive on the job and occupants feel more comfortable in their building.
3 inch Linacoustic
New 3-in. liner should be valuable to contractors working in those climate zones 5-8. This insulation is designed specifically to meet the new code requirements set forth by the IECC in 2015 that mandate the use of R-12 insulation on ducts in unconditioned spaces. Prior to the new Linacoustic RC product, single-layer, flexible R-12 duct liner was not an available option for the market. As a result, contractors were forced to use two layers of insulation to meet the R-12 standard. The new R-12 duct liner meets the code in just one layer.
