Basic Use: ToughGard™ Duct Board with Enhanced Surface is a rigid board designed for fabrication into supply and return air duct work for residential and commercial heating, ventilating air conditioning systems which operate at velocities up to 5,000 fpm (25.4 m/s) and temperatures up to 250°F (121°C) and maximum internal pressures of ± 2" (51mm) water gauge.

Benefits: ToughGard Duct Board with Enhanced Surface systems provide excellent thermal properties, absorbs unwanted crosstalk, equipment and air rush noise, and resists microbial growth. The ToughGard airstream surface is extremely tough and durable providing exceptional resistance to damage during fabrication, installation and cleaning, as well as allowing higher system operating velocities.
