This is a waterproofing membrane reinforced with fiberglass, composed of modified asphalts with mineral fillers and special polymers that provide rigidity, stability, and flexibility to the product. The upper surface features an embossed and lacquered aluminum foil finish, with colored lacquer or transparent coating, giving it a protective and decorative final touch. The lower surface is made of fusible plastic. It is used for waterproofing: concrete roofs, metal roofs, tongue and groove, expansion joints (walls and foundations), and terraces where a colorful and protective finish is desired.
