Designed for fabrication into supply and return air ductwork, this lightweight duct board is easy to install. Tough, durable and easy to clean, the fire-resistant black composite air stream surface and built-in vapor retarder resists microbial growth, thereby reducing the chance of condensation damage. ToughGard duct board is made of resin bonded glass fibers with a reinforced foil laminate air barrier/vapor retarder facing applied to the outside surface. The low leakage rate and increased thermal and acoustical propertiesimprove the overall quality of the indoor environment while delivering increased energy savings.
- The fiber glass acoustical insulation attenuates unwanted cross talk, air rush and equipment noise
- The exceptional low leakage rate (SMACNA class 6), in combination with the thermal efficiency of ToughGard and Ultra Duct black, means savings in energy and improved system performance
- The built-in vapor retarder on ToughGard and Ultra Duct black reduces the chance of condensation and the resulting chance of material and system damage caused by unwanted moisture
- ToughGard's tough air stream surface makes it resistant to fabrication, jobsite and installation damage and provides extra protection during system cleaning
- The air stream surface of CertainTeed duct board contains an EPA registered antimicrobial agent to reduce the potential of microbial growth that may affect this product
