Ductmate’s new ProGuard is a film with a high-tack adhesive designed to protect the inside of ductwork from dust, dirt and other particles that can lead to poor indoor air quality. ProGuard, which is designed to be placed over the opening of the ductwork, has a specially formulated adhesive that keeps the film attached to the ductwork during storage and transportation, but leaves no residue when removed. ProGuard reports that its manufacturing process gives it the flexibility and workability of a thin film with the toughness of thicker products.
