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..
Micro-Aire® Duct Board, Mat-Faced, Series: 475, 120 in Length, 48 in Width, 1-1/2 in Depth, For Use With: Ventilating and Air Conditioning System, Fiber Glass
Data/Spec Sheet-1- 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
- 5000 fpm air velocity
- Cleanability: 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
