Ultra-Duct Gold is a rigid board designed for HVAC duct systems with an airstream facing that reduces the amount of nuisance dust generated during fabrication, according to the company. The mat airstream facing is also designed to improve handling, and the board can handle system operating at twice the velocity of the company's previous standard duct board products. The product is composed of resin-bonded glass fibers with a reinforced foil laminate air barrier vapor facing applied to the outside surface and a fiberglass textile mat bonded to the airstream surface.
