EPD: Bitumen roof waterproofing membrane, base layer, 2.6 mm, 4.09 kg/m2, SOPRASTICK VENTI NEO FF (SOPREMA NV)
Self-adhesive membrane with a vapour-pressure and tension dispersion system, composed of elastomer modified bitumen and a fiberglass-grid combination 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. Energy consumption and used ancillary materials during installation are considered and are based on the average installation scenario of the product. The installation phase includes 10% overlapping material. The membrane has a reference service life of 70 YEARS, if combined with Soprema top layer.
