  • Permacote Linacoustic® R-300 helps improve indoor environmental quality by helping to control both temperature and sound
  • Permacote Linacoustic® R-300 has exceptional sound absorbing properties far exceeding the requirements of ASTM C1071
  • Duct transmitted noise, such as crosstalk and sound energy from air movement and mechanical equipment, is noticeably reduced
  • The tough, acrylic polymer Permacote coating helps guard against incursion of dust or dirt into the substrate, minimizing the potential for biological growth
  • Permacote coating is formulated with an immobilized, EPA registered, protective agent to protect the coating from potential growth of fungus and bacteria
  • Permacote Linacoustic® R-300 has been tested to the recommended maximum velocity of 6000 fpm (30.5 m/s)
  • Fiber erosion test results were determined using the Isokinetic Sampling Method described in Johns Manville fiber erosion testing fact sheet HSE-133FS
  • If necessary, the surface may be cleaned using standard industry recognized dry methods
  • North American Insulation Manufacturers Association (NAIMA) cleaning fibrous glass insulated air duct systems
  • The specially designed Permacote airstream surface enhances the ability of R 300 to resist damage from typical in-shop handling, fabrication and jobsite shipment
