The 90005696 Fiberglass Ductboard is produced from durable glass fibers, bonded with a thermosetting resin. The airstream side of Mat-Faced Micro-Aire Duct Board features a fiber glass mat for use at velocities up to 5,000 fpm (25.4 m/sec.).

The opposite side features a fire-resistant Foil-Scrim-Kraft facing extending the full width of the male edge as an integral closure flap for section joints. Mat-Faced Moicro-Aire Duct Board is molded with double-density, male/female edges for secure connections. It 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.

Advantages:

• Durable Air Stream Surface Mat-Faced Micro-Aire Duct Board exhibits superior toughness compared to standard fiber glass duct board. It provides increased resistance to damage that can occur from in shop handling, fabrication, job site shipping and installation.

Cleaning Firous Glass Insulated Air Duct Systems

• The airstream surface may be cleaned using standard industry-recognized dry methods.

Friendlier Feel

• The smooth mat facing creates a friendlier surface for fabrication and installation, and reduces exposure to normal construction dust.

Quiet Operation

• Fabricated Mat-Faced Micro-Aire duct systems noticeably decrease the audibility of crosstalk, equipment noise and eliminates the sounds associated with the expansion and contraction of sheet metal duct systems.
