Designed for fabrication into supply and return air duct work for both residential and commercial heating, ventilating and air conditioning systems. CertainTeed duct board products can be fabricated into square, rectangular or multisided sections. Standard, factory-molded male and female shiplap edges ensure tight and strong fabricated transverse joints.
- 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
