Certificate type
Styrene-butadiene-styrene (SBS) modified bitumen capsheet membrane with 180 g/m² composite polyester reinforcement.
Used as single layer waterproofing on surfaces where partial adhesion is required.
Membrane composed of styrene-butadiene-styrene (SBS) modified bitumen with composite polyester reinforcement. The upper surface is finished with slates, with the selvedge protected by a polypropene film. The lower surface has thermally activated SBS stripes alternated with non-stick stripes, protected by a thermofusible film.
