Mat-Faced Micro-Aire® duct board is produced from strong glass fibers, bonded with a thermosetting resin. The airstream side of Mat-Faced Micro-Aire duct board features a black fiber glass mat, which minimizes visibility of the duct system at supply air and return air outlets while providing excellent durability in high-velocity conditions. The exterior surface features a fire-resistant foil-scrim-kraft facing extending the full width of the male edge to serve as an integral closure flap for section joints. Mat-Faced Micro-Aire duct board is molded with double-density, male/female edges for secure connections.
  • Features
  • Standards & Approvals
  • Application
Durable airstream surface - Mat-faced Micro-Aire® exhibits superior toughness compared to standard fiber glass duct board, It provides increased resistance to damage that can occur from in-shop handling, fabrication, jobsite shipping and installation
Low resistance to air flow - Mat-faced Micro-Aire® duct board has a smooth interior surface that offers minimal resistance to air flow
Quiet operation - Fabricated mat-faced Micro-Aire® duct systems noticeably decrease the audibility of crosstalk, equipment noise, and eliminate the sounds associated with the expansion and contraction of sheet metal duct systems
Will not support microbial growth - The airstream surface of mat-faced Micro-Aire® duct board is treated with an antimicrobial agent specifically registered with the EPA for HVAC applications to resist potential growth of fungus or bacteria on the airstream surface
Mat-faced Micro-Aire® duct board passes UL 181 mold growth resistance testing
Cleanability - If cleaning is necessary, the airstream surface may be cleaned using standard industry-recognized dry methods
Noise reduction coefficient (NRC): 0.85 (R6.5)
10% recycle content
Friendlier feel the smooth mat facing creates a friendlier surface for fabrication and installation and reduces exposure to normal construction dust
Mat-Faced Micro-Aire® duct board is ideal for fabrication into rectangular ductwork for use in heating, ventilating and air-conditioning systems in new commercial or residential construction, or for renovating older sheet metal systems
Mat-faced Micro-Aire® duct board should be kept clean and dry during storage, transport, fabrication, installation and system operation
