Tack Bank Foil is a roll of flat, high-tack adhesive tape available between 100mm and 200mm widths. It provides a waterproof seal over roof joins and is commonly used where the roof sheet or roof structure joins the supporting building or where there are major intersections on stand-alone roofs (e.g. Pergolas).
The outer side is a 'lead look' matt-type finish, and the other is the hi-tack, sticky side. It is a thin layer of butyl tape that has the consistency of a very sticky putty, and once it touches a surface, it is 'on'. Once pressed in place, it is not designed to be lifted and moved, so care should be taken when placing it, and only remove the thin cover film when you are finally ready to fix it in place.
