Diffusor Boardâ„¢ mat-faced fiberglass duct board is ideal for fabrication into rectangular ductwork for HVAC systems in new construction, as well as renovating old sheet metal systems, says the manufacturer. The company states that it is molded with double-density, male and female edges, to ensure more secure connections. The airstream surface is treated with an antimicrobial agent, designed to resist fungus or bacteria growth on the airstream surface. The duct board decreases the audibility of crosstalk and equipment noise, and it eliminates the sounds associated with the expansion and contraction of sheet metal duct systems, the manufacturer states.
