Product Features
Applications: Air Conditioning, Heating and Ventilating System, Commercial and Residential Applications
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
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
10% recycle content
Friendlier feel the smooth mat facing creates a friendlier surface for fabrication and installation and reduces exposure to normal construction dust
Shipped With E3 PalletTM Technology - The E3 Pallet is designed to simplify repurposing our 4x8 and 4x10 pallets into more functional, 48x48 and 48x40 pallets (respectively)
