  • Integrated self-adhesive strips
    The integrated self-adhesive strips ensure that overlaps can be glued directly. They also prevent the penetration of moisture and cold air to the insulation, thereby ensuring best protection.
  • Extremely flexible
    DELTA-XX PLUS® LIGHT impresses with good malleability, meaning the membrane can also be applied conveniently for difficult details. The flexible material ensures greater security in the event of unintentional contact with the toe cap (ladder) and tools.
  • Prevents reflected glare
    The matt surface of DELTA-XX PLUS® LIGHT reduces troublesome glare. That makes work considerably more pleasant.
