Ultra*Duct™ Gold is a rigid board designed for HVAC ductwork systems. It has an airstream facing that significantly reduces the amount of nuisance dust generated during fabrication, compared to other standard duct boards, claims the company. The duct board is composed of resin-bonded glass fibers with a reinforced foil laminate air barrier vapor retarder facing applied to the outside surface and a fiberglass textile mat bonded to the airstream surface. According to the company, it can handle conditioned air temperatures up to 250 degrees F (121 degrees C), air velocities up to 5,000 fpm, and maximum internal pressures of ±2-inches (5-mm) water gauge. The duct board is available in 1- and 1-1/2-inch thicknesses.
