The ToughGard®2 textile duct liner has features and benefits specially designed to meet the energy requirements of Title 24 of California's Energy Efficiency Standards for Residential and Non-Residential Buildings. The newer variation of the duct liner includes two types: one that achieves thermal values rated at R-4.2 at 1 inch and the other rated at R-6.3 at 1.5 inches. The improved noise-reduction coefficients are 0.7 for the 1-inch duct liner and 0.9 for the 1.5-inch product. The duct liner's airstream surface repels liquid water that may enter a duct system. This surface contains an EPA-registered antimicrobial agent in order to reduce the potential of microbial growth that may affect the product.
