The tapes consist of two strips of aluminum, between which a polypropylene net with a high breathability is located. Specially contoured edges allow installation on any type of roofing material and are used for the efficient discharge of water from precipitation. The butyl coating placed on the banks allows permanent joining with the roofing. The tape can be used on porous and smooth surfaces, but note that the glued surface should be free of grease and dust.
