Abstract
An improved fiber glass air duct board is provided for the manufacture of insulated air ducts. The board features an air surface facing means providing a smoother interior surface that engages the air flowing through the duct. The smoother surface afforded by the facing reduces friction loss of the air flowing through the ducts as well as reduces the accumulation of dust and dirt within the ducts. Further, the facing provides an additional means for treating the interior of the ducts with biocides to reduce the likelihood of microorganisms surviving in the interior walls of the duct. In the preferred method of manufacturing the duct made in accordance with the present invention, the surface facing is applied to the upper surface of the fiber glass before it is transferred into the flighted oven.
