ELASTOFLEX SA P is a top-quality prefabricated SELF-ADHESIVE bitumen membrane produced using ADESO® technology, the innovative ELASTOMERIC (SBS) compound laminating system. In the ADESO® membranes, the exclusive SEALLap® polyurethane self-adhesive system further improves the bond along the side laps of overlapping membranes as they are applied. In the mineral versions, the ADESO® membranes feature the FASTLap® system, the head selvedge free from slate chippings, which allows a faster and easier application and a better sealing of the overlaps. ELASTOFLEX SA P is a membrane produced to the standards set by NAT® technology, the production system for the control of polymer matrix ageing in bitumen membranes. ELASTOFLEX SA P has a polyester nonwoven carrier, stabilized with glass strands parallel to the machine direction. The carrier gives good puncture resistance, dimensional stability, and tensile strength in all directions.
