    Roofing membrane, Roofing membrane for hard sheathing DELTA-XX PLUS® HEAVY

    The combination of layers with varying performance makes the breathable soft sheating and sarking sheet particularly robust – over the course of many years. Because its proven longevity ensures a lastingly secure roof. Its great robustness means it offers optimal protection during installation.

    The extremely resistant roofing membrane is tailored perfectly for use on roofs with formwork. Naturally, it is also suitable for use on fully insulated roofs without formwork.

    • Practical self-adhesive strips
      The integrated self-adhesive edging strip fast and secure adhesion of roofing membranes overlaps. This means that neither cold air nor moisture can enter the insulation, increasing efficiency.
    • Highly breathable
      The permeable functional layer between the spun fibre fabrics ensures very high breathability. Building moisture and condensation in the structure can therefore dry again swiftly. The breathability lies far above that of bitumen-based roofing membranes and many types of plastic sheeting.
    • Optimised for roofs with formwork
      The heavy and thick fabrics of DELTA-XX PLUS® HEAVY optimally protect the functional film of the roofing membrane on rough surfaces. This means that already during installation it is certain that the membrane will offer the roof truly long-lasting protection

     

    Application

    DELTA-XX PLUS® HEAVY is the robust solution for roofs with formwork and meets the requirements of ZVDH product data sheets UDB-A and USB-A. The roofing membrane can also be used as temporary roofing for the provisional protection of a roof. In addition, it is also suitable for use as base layer under metal roof coverings, fibre cement panels or slate and as façade membrane behind ventilated cladding with closed joints.
