Duct Wrap is composed of glass fibers bonded together with thermosetting resin. It helps to control heat loss and condensation during HVAC system operation. It can handle conditioned air at temperatures from 35-250°F for faced duct wrap and 35-350°F for unfaced wrap. It is a lightweight, foil faced, fire retardant blanket-type insulation with multiple uses. It has no fiberglass and does not itch or cause skin irritation. It is available with a 1″ or 2″ quilted fiberglass decoupler. It is also used to wrap noisy pipes and ducts to block the noise that transmits through the walls of the pipe or duct as air.
