SOPRASTICK VENTI FF
Self-adhesive membrane with a vapour-pressure and tension dispersion system, composed of SBS modified bitumen and a composite polyester reinforcement.
Used as an under 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.
