Art.No. 51131


SBS-modified bitumen membrane with aluminium composite and glass-fibre reinforcement

The upper side is equipped with adhesive areas by thermal activation for the bonding of EPS thermal insulation.

Top side / Bottom side

Top side

Sand with integrated thermal activation stripes (foil)

Thermal activation selvedge of 10 cm on both sides (foil)

Bottom side


Intended use

  • Vapour control layer


Torch-on method

Side and end laps min. 10 cm overlap

The stick on of polystyrene insultation plates needs to be done immediately after thermal activation of the of the adhesive areas (by melting away the upperside foil with a burner)
