Art.No. 55089


Self-adhesive SBS-modified bitumen membrane with aluminium composite, composite reinforcement and anti-slip surface

The membrane is eqipped with an additional torch-on selvedge to torch the side laps (e.g. if the temperature is below the recommended minimum application temperature). This prevents the below layer from thermal damages by torching.
