SOPRASTICK VENTI FF

Self-adhesive membrane with a vapour-pressure and tension dispersion system, composed of elastomer modified bitumen and a composite polyester reinforcement. Used as a base layer within a multi layer waterproofing system on surfaces where partial adhesion is required. The upper surface is protected by a thermofusible film. The lower surface is provided with self-adhesive bitumen stripes alternated with non-stick stripes protected by a silicone release film. The overlap is partly self-adhesive (to prevent flame transmission) and partly torchable with flame or hot air.
