Duct board with water repellant mat

Image Number 8 for United States Patent #7223455.

A duct board or duct liner comprises: an insulating layer formed from fibrous material bound with a resin binder, an outer facing layer adhered to an outer surface of the insulating layer, and a water repellant mat facing adhered to an interior surface of the insulating layer opposite the outer surface to form a duct board material. The mat facing provides sufficient water repellency to repel a mixture of about 40% isopropanol and about 60% water. The duct board or duct liner material may be formed into a tubular shape capable of conducting air, with the mat facing on the interior of the tubular shape.
