ProGuard

ProGuard is a dual film polyethylene film with a high-tack adhesive designed designed to be placed over the opening of the ductwork during storage and transportation, to protect the inside of ductwork from dust, dirt, and other particles that can lead to poor indoor air quality. ProGuard is specially formulated to keep the film attached, leaving no residue when removed. Its unique manufacturing gives ProGuard the flexibility and workability of a thin film with the toughness of a thick 4.5 mil product.
