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 strength 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..

    • 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, air friction data is available from your johns manville representative by requesting AHS-165
    • 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
    • 250 deg F temperature
    • Clean ability - if cleaning is necessary, the airstream surface may be cleaned using standard industry recognized dry methods, see the north american insulation manufacturers association (NAIMA) cleaning fibrous glass insulated air duct systems
    • Friendlier feel the smooth mat facing creates a friendlier surface for fabrication and installation, and reduces exposure to normal construction dust
