  • Integrated adhesive strips
    Particularly practical are the integrated adhesive zones on both edges, enabling swift and reliable gluing of overlaps. At the same time, they also keep out cold air and moisture. This ensures more efficiency, comfort and cost savings

    The four-layer structure of the membrane comprises a spun-bonded fabric foil combination with integrated, strong grid reinforcing. This means that DELTA-XX PLUS® STRONG is especially robust and tear resistant. An advantage that makes installing the membrane considerably safer and also delivers long-term protection for the roof.
