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 multiside sections. Standard, factory-molded male and female shiplap edges ensure tight and strong fabricated transverse joints.

Composed of resin-bonded glass fibers with a reinforced foil laminate air barrier/vapor retarder facing applied to the outside surface and a textile fiber glass non-woven mat bonding to the air stream surface.

  • Quiet System: The fiber glass acoustical insulation attenuates unwanted crosstalk, air rush and equipment noise.
  • Lower Operating Costs: 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.
  • Reduces Condensation: 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.
  • Durability and Cleanability: ToughGard’s tough air stream surface makes it resistant to fabrication, job site and installation damage and provides extra protection during system cleaning. Ultra*Duct Black and ToughGard duct board can be cleaned effectively with industry recognized duct cleaning equipment and procedures as outlined in the North American Insulation Manufacturers Association (NAIMA) Duct Cleaning Guide. Proper design, filtration, maintenance and operation of the HVAC system will reduce the need for cleaning.
  • Resists Microbial Growth: 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. The antimicrobial properties are intended to only protect this product.

ToughGard and Ultra*Duct Black perform at air velocities of up to 5,000 fpm (25.4 m/s). Both also perform at maximum internal pressures of ± 2" (51 mm) water gauge, and 250°F (121°C).

Duct board products regularly meet the requirements of the following current specifications, standards and codes:
  • Material Specifications UL181 for Factory Made Air Ducts and Air Connectors, Class 1 Rigid. Closure systems must meet the requirements of UL 181A.
  • Fire Safety Standards NFPA 90A, NFPA 90B
  • Building Code ICC
  • GREENGUARD® Children & Schools

All fabrication, application and installation steps shall be in compliance with the NAIMA Fibrous Glass Duct Construction Standard or the SMACNA Fibrous Glass Duct Construction Standard and the project specification. Refer to CertainTeed installation manuals or CertainTeed specification data sheets for installation guidelines.

An inspection and preventative maintenance program for the HVAC system is recommended to ensure optimum performance.
