ToughGard Duct Board is designed for fabrication into
supply and return air duct work for residential and commercial
heating, ventilating and air conditioning systems. This
durable, lightweight resin-bonded glass fiber board reduces
condensation, resists bacteria growth and provides a
quiet HVAC system. It also saves energy by combining
thermal efficiency with an exceptional low leakage rate.
Composed of durable, lightweight resin-bonded glass fiber board with a black
mat facing on the air stream surface and a built-in vapor retarder on the outside,
Duct Board can be fabricated into square, rectangular or multi-side sections.
