Soprastick

Used as a vapour barrier for buildings with high moisture production.

Self-adhesive membrane composed of elastomer modified bitumen and a composite polyester reinforcement.

Used as a base layer in combination with a torched upper layer.

The upper surface is protected by a thermofusible film.

The overlap is partly self-adhesive (to prevent flame transmission) and partly torchable with flame or hot air. The self-adhesive lower surface is protected by a silicone release film.
