- Absorbs Disturbing Sound. Permacote Linacoustic R-300 has exceptional soundabsorbing properties far exceeding the requirements of AS™ C1071. Ducttransmitted noise, such as crosstalk and sound energy from air movement and mechanical equipment, is noticeably reduced.
- Resistant to Dust and Dirt. The tough, acrylic polymer Permacote coating helps guard against incursion of dust or dirt into the substrate, minimizing the potentialfor 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 fungus and bacteria.
- Withstands High Velocity. Permacote Linacoustic R-300 has been tested to the recommended maximum velocity of 6,000 fpm (30.5 m/sec). Fiber erosion test results were determined using the Isokinetic Sampling Method described in Johns Manville Fiber Erosion Testing Fact Sheet HSE-133FS.
- Cleanability. If necessary, the surface may be cleaned using standard industry-recognized dry methods. See the North American Insulation ManufacturersAssociation (NAIMA) “Cleaning Fibrous Glass Insulated Air Duct Systems.â€
- Resists Damage. The specially designed Permacote airstream surface enhances the ability of R-300 to resist damage from typical in-shop handling, fabrication andjobsite shipment.
